    Description: This is the Salmonid & Freshwater Fisheries Statistics for England & Wales 1992 produced by the National Rivers Authority (NRA) in 1994. This report is focused on the maintenance, improvement and development of fisheries of England and Wales. This report is the fourth compilation of salmon and migratory trout catch statistics for England and Wales published by the National Rivers Authority. For the years 1983-88, these statistics were published by the Ministry of Agriculture, Fisheries and Food (MAFF), Directorate of Fisheries Research in their Data Report Series. Other than for rod catches, the 1992 data have been presented in a broadly similar format to those of 1991, Presentation of the rod data however has changed considerably due to the introduction in January 1992 of the first National Rod Fishing Licence. This report makes a general review of different catches: Northumbria, Yorkshire, Anglian, Thames, Southern, Wessex, South West, Severn-Trent, Welsh and North West.

    Description: This is the River Ehen and Tributaries SSSI consultation Protocol for the Environment Agency with English Nature, produced in 1998. The Protocol is intended to provide for consistency of approach, to clarify responsibilities and help to streamline the statutory consultation and consenting procedures in which both organisations are involved. It provides guiding principles on the approach to management issues. Based on the operations likely to damage the special interest (OLDSI) which forms part of the SSSI notification, the protocol identified acceptable management activities which contribute to the special interest of the site and those which may adversely affect that interest. OLDSI includes activities such: land drainage consents, discharge consents, herbicides approvals, fish-stocking consents, fishing licences, abstraction and impoundment licences, consents to construct/test pump boreholes, integrated pollution Control Licences and Waste Management Licences, capital projects, flood defence maintenance works, water resources, fisheries, pollution control, ecology surveys and Recreation works.

    Description: This is the Acid waters in North West England: The effect of liming agricultural land on the chemistry and biology of the River Esk, North West England report produced by National Rivers Authority in 1992. This report focuses on the study of Acid Waters in the North West Region of England, UK, which began in 1982 and sampling was completed in October 1990. This work was initiated because of the observation of the simultaneous mortality of adult and juvenile salmon and sea-trout in both the River Esk and adjacent River Duddon in June 1980. Investigations at that time indicated that an "acid episode" was the most likely cause of this mortality. A land use study indicated that a reduction in agricultural liming may have been a major factor in the development of acid episodes and consequent fish kills in the River Esk and River Duddon. However there was no evidence that the mortalities of salmonids in the early 1980's were due to a reduction in agricultural liming. They were due to some other phenomenon such as a period of intense acid deposition.

    The history of contamination in sediments from the Mersey Estuary. Development of a chronology for the contamination of the Mersey Estuary by heavy metals and organochlorines (2021)

    Description: This is the history of contamination in sediments from the Mersey Estuary: Development of a chronology for the contamination of the Mersey Estuary by heavy metals and organochlorines Report produced by the Environment Agency in 1998. This report looks at the history of industrial contamination of the Mersey and Ribble Estuaries back to the early part of the last century, many decades before the start of monitoring programmes providing a remarkably detailed picture of very complex changes. There is a clear record in the sediment of the contamination by each heavy metal (including: Cu, Cr, Hg, Pb, Zn) and organochlorine chemical (including DDT isomers and PCB congeners) studied. The results of the study clearly show the increases in levels of contamination as industry expanded early last century followed by various improvements as this century progressed. Each pollutant has its own idiosyncratic pattern of change with some improvements predating modern environmental concerns whilst other changes seem to relate directly to recent improvements in legislative control. Overall, for the pollutants studied, the results clearly demonstrate the magnitude of improvement that has been achieved in what was a very polluted area. The only major reservation to this story is that despite the wide range of substances covered, many other potentially important pollutants remain to be studied in a similar manner.

    Description: This is the Mersey Estuary baseline survey: Analysis of macroinfaunal samples, literature review and database production report produced by the Environment Agency North West in 2002. This report presents an ecological review of the Mersey estuary along with an extensive bibliography of the available environmental literature for this system. The central objective of this programme has been to provide the information necessary to support the Environment Agency's review of existing and future consents (for discharges, abstractions etc) in the Mersey estuary. This review of consents was required because the Mersey had been designated as a Special Protection Area (SPA) under the EC Birds Directive. Therefore under Regulation 50 of the Conservation, the Environment Agency was responsible for reviewing any extant consent, or future applications, which may directly or indirectly, affected this SPA.

    Description: This is the Wetland resource evaluation and the NRA's role in its conservation: Resource assessment report produced by the National Rivers Authority in 1995. This R&D document provides a strategy for the assessment of the wetland resource of England and Wales. As a first step the report defines wetlands in their UK context. The following working definition is suggested: Wetland is land that has (or had until modified) a water level predominantly at, near, or up to 1.5 m above the ground surface for sufficient time during the year to allow hydrological processes to be a major influence on the soils and biota. These processes may be expressed in certain features, such as characteristic soils and vegetation. The report also summarises a hydrotopographical classification of wetlands. The report then develops a strategy for the establishment of a wetland resource Inventory based on a geographical information system (GIS) as a means of storing and manipulating site data from across England and Wales.

    Wetland resource evaluation and the NRA's role in its conservation. Classification of British wetlands (2021)

    Description: This is the Wetland resource evaluation and the NRA's role in its conservation: Classification of British wetlands report produced by the National Rivers Authority in 1995. This R&D document provides a clear classification for wetlands in England and Wales. The classification incorporates many of the existing ideas on the subject but avoids some of the problems associated with other classifications. A two-layered 'hydrotopographical' classification is proposed. The first layer identifies situation-types, i.e. the position the wetland occupies in the landscape, with special emphasis upon the principal sources of water. The second layer identifies hydrotopographical elements, i.e. units with distinctive water supply and, sometimes, distinctive topography in response to this. This system is seen as an independent, basic, classification upon which it is possible to superimpose additional, independent classifications based on other features (e.g. base-status, fertility, vegetation, management etc.). Some proposals for such additional classifications are provided.

    Description: This is the report on the strategic fisheries stock assessment survey of the minor catchments in South West Cumbria 1996 with particular reference to salmonids, produced by North West Water in 1994. The 1996 Minor Catchment survey indicates variations in salmonid production within these catchments. Survey results indicate that production may be reaching its limit in certain areas whilst others are underachieving and others are unsuitable for salmonid production. Trout production within the catchments is higher and more widespread than that of salmon. Water quality levels vary considerably between catchments and intra-annually within individual catchments. The need for selective habitat surveys, with a view to habitat improvement schemes (H.I.S) is discussed. This report formed a basis for subsequent reports, thus, allowing data comparisons and analysis of production level fluctuations. It was the most extensive assessment of these catchments to date, taking into account comparisons with the new National Database on salmonid production in England and Wales.

In 1996 the National Rivers Authority (NRA) report on the 1992 strategic stock assessment for the Upper Derwent catchment Jane Atkins recommended that should subsequent electrofishing show continued low densities, a survey of the invertebrate fauna should be undertaken to assess the food availability for salmonids, in order that lack of food could be ruled out as a contributory factor in their poor breeding success. Additionally the survey looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

    Description: This is the report on Habitats Directive, the Review of Consents Stage 1 and 2 by the Environment Agency of the South Pennine Moors cSAC/SPA.The Habitats Directive has the main aim to promote the maintenance of biodiversity by defining a common framework for the conservation of wild plants and animals and habitats of community interest. The Directive establishes a European ecological network known as "Natura 2000". The network comprises Special Areas of Conservation (SAC) and Special Protection Areas (SPA). In the section on Stage 1 or Screening Process of the Habitat Directive, it is identified the likely impacts upon the Rixton Clay Pits cSAC of a project, plan or activities, either alone or in combination with other projects, plans or activities, and considers whether these impacts are likely to be significant. In the section on Stage 2 or Appropiate Assessment of the Habitat Directive, it is considered the impact on the integrity of the Rixton Clay Pits cSAC of the projects, plans or activities, either alone or in combination with other projects, plans or activities, with respect to the site’s structure and function and its conservation objectives. Additionally, where these are adverse impacts, an assessment of the potential mitigation of those impacts. The criteria used in this report to identify relevant projects, plans or activities and their impacts are water quality discharge consents, waste management licences, abstraction licences, Integration Pollution Control (IPC) and Integrated Pollution Prevention Control (IPPC) permits. Proformas, hydrogeological and GIS maps are included in the review.

    Description: This is the Water Quality Monitoring in the Mersey Estuary report produced by the Environment Agency in 2001. This report focuses on the Water Quality Monitoring Programme held in the Mersey Estuary. Since the mid-1960s water samples have been collected at approximately monthly intervals along the length of the estuary between Warrington and New Brighton and in later years further off-shore. This data-set provides an invaluable resource to determine how the very large capital spending of recent years has resulted in the dramatic improvements in water quality that we are now able to record. Initially, the interest was focused on parameters such as dissolved oxygen, BOD, nutrients and suspended solids. Over the last decades, as analytical methods have improved, toxic metals and persistent organic compounds have been included in the routine monitoring programme at a limited number of sites. Moreover, with the introduction of the European Water Framework Directive monitoring programmes it was an opportune time to review the Mersey monitoring strategy. This revised monitoring programme required data from several other components (water, sediments, flora, fauna, fish and birds. This report also contains information about Routine monthly surveys, Special surveys, Chloralkali Directive, UKNMP, British Geological Survey, EDMAR and NERC Environmental Diagnostics Thematic Programme.

    Description: This is the report on the strategic fisheries stock assessment survey of the River Winster 1995 together with a coarse fish survey in 1994 and reference to the 1995 drought, produced by the Environment Agency North West in 1996. Salmonid production within the Winster catchment was dominated by trout although good densities of salmon juveniles were found on some main river sites. Despite suffering drought conditions for much of 1995, only salmon fry production appeared to have been affected. Coarse fish populations once found in the lower reaches of the Winster appear to have declined to very low levels with no fish sampled. This may be partly due to broken tidal gates allowing saline intrusion. It seems that the lower river was suited to the development of a recreational coarse fishery, now that the gates have been repaired. This report completes the strategic stock assessment surveys planned for the period 1992-1995. It represents the last major catchment that was surveyed to determine the current status of fisheries in the South and South West Cumbria areas.

    Description: This is the report on the Leven estuary project: Fisheries Department final report produced by the Environment Agency North West in 1997. This report contains information about Leven estuary, river Leven catchment, river Crake catchment and the Ulverston Discharges. The Leven estuary is characterised by being very shallow, and shares the extremely variable tides and currents that characterize the whole of Morecambe Bay. There was little detailed knowledge of the impact on the Leven estuary, and particularly its fisheries, of the discharges from Ulverston. There has been some concern expressed by the lave netsmen and the general public about the possible harmful effects of the effluents on the biology of the estuary. In the absence of a definite strategy for the protection and management of the estuary was born this project. The project involves water quality monitoring, effluent and estuary toxicity testing, tracking of effluent plumes, and salmonid tagging and tracking. The entire project commenced in June 1995 and was expected to reach a conclusion in March 1997. The information gained from the project was expected to contribute to the creation of a 'mixing zone' for the effluent, and to improve the environmental management of the estuary and protection of its fishery.

    Description: This is the Brown trout habitat assessment on the River Bela catchment produced by the Environment Agency North West in 1997. The Environment Agency (EA) and its predecessor the National Rivers Authority undertook strategic fish stock assessments in 1992 and 1995 on the River Bela catchment. These surveys found low numbers of brown trout {Salmo trutta) at some sites. Following this, habitat evaluation assessments were undertaken on the eleven poorest sites Factors probably responsible for declining trout populations on the three main tributaries of the Bela catchment include: Overgrazing by farm stock; Lack of suitable cover for parr; the absence of suitable spawning areas; existing potential of certain areas within the catchment not being utilised, due to poor dispersal. Habitat Improvement Schemes (H.I.S) are discussed and prioritised.

    Description: This is the report on the River Ehen salmonid fishery - current status and a summary of fisheries work during the period 1993-1996, produced by the Environment Agency North West in 1997. This report draws together a number of investigations and surveys undertaken following the 1993 Strategic fisheries survey of the River Ehen. It specifically details the historic catch data available for this catchment for both salmon and sea trout and examines the current stock levels based on this data. Concerns over sea trout stock levels are raised and a detailed examination of the possible limiting factors involved is included. Information from surveys on the River Keekle is analysed with reference to its potential for sea trout production both currently and with the proposed clean up on Oatlands tip. Salmon production in the historically acidified River Liza sub catchment is examined along with ways of boosting production further following recent reductions in acidic episodes. Future and current issues and actions required in the catchment are listed along with the responsible party and estimated costs involved.

    Description: This is the Cheshire stillwaters summary results 1999 from the Environment Agency North West. In May 1997, a Stillwaters meeting was held to discuss the way forward in stillwaters monitoring. It decided upon the establishment of a three year rolling programme, in which three stillwaters would be monitored three times a year, every third year. During 1999, stillwaters monitored for the third year of the Stillwaters Monitoring Programme were Tabley Mere, Comber Mere and Norbury Mere. Surveys of Petty Pool and Betley Mere continued for a second and third year respectively after water quality concerns were highlighted in previous end-of-year reports. Oak Mere was also surveyed for the third year running due to its unusual ecology. This year, the variety of parameters monitored was limited to algal, zooplankton and water chemical samples. Fisheries and marginal invertebrate surveys were not completed due to lack of resources.

    Description: This is the report on Lakes – Classification and Monitoring, a strategy for the classification of lakes by the National Rivers Authority.This report describes a scheme for the assessment and monitoring of water and ecological quality in standing waters, greater than about 1ha in area, in England and Wales although it is generally relevant to Northwest Europe. Thirteen hydrological, chemical and biological variables are used to characterize the standing water body in any current sampling. Statistical testing on the chemical variables showed that at least six samples during a year would be needed to produce a representative sampling mean; but in this scheme the choice of variables minimizes logistic cost by not using boat sampling and time costs by not demanding extensive taxonomic work. Standing waters are classified in a state-changed system in which the contemporary values of the variables are compared with a reference baseline state and then placed in categories of percentage change from this baseline. The scheme is presently designed for use at about five year intervals on all lakes greater than 2ha area plus additional lakes of significant amenity or conservation interest.

    Description: This is the Stillwaters monitoring programme. Summary results 2001 and 2002 from the Environment Agency North West. Until January 2001 the South Area Stillwaters Sampling Programme consisted of a rolling programme where five to six stillwaters were sampled three times a year (spring, summer and autumn). However, this method was not yielding the water quality information required for long term monitoring. Local weather conditions influence short-term water quality events, e.g. algal blooms, nutrient consumption, stratification, super-saturation etc, so results from one day sampling could only be regarded as individual ‘spot’ samples. Therefore year-on-year comparisons could not be made. It was decided that long-term water quality monitoring of the stillwaters would benefit more from sampling nutrient abundance over winter months. This would give an insight into the carry-over of nutrients available for algal growth the following year and so year-on-year productivity could be assessed. Survey results shown in this report were from: The Mere, Rostherne Mere, Melchett Mere, Tabley Mere, Tatton Mere, Hatchmere, Oak Mere, Black Lake, Chapel Mere, Bar Mere, Oss Mere, Marbury Big Mere, Comber Mere and Betley Mere.

In May 1997, a Stillwaters meeting was held to discuss the way forward in stillwaters monitoring. It decided upon the establishment of a three year rolling programme, in which three stillwaters would be monitored three times a year, every third year. The stillwaters where chosen due to water quality (i.e potential polluted / sensitive waters), fisheries and ecological interests. The Still waters chosen for the first year (1997) were Oak Mere, Betley Mere and Marbury Big Mere. The surveys were aimed to produce a comprehensive study of the still water through monitoring a variety of parameters. Algal, zooplankton and water chemical samples were taken three times a year, (April, July and September). In addition, fisheries surveys were taken in July and marginal invertebrate surveys taken in September.

    Description: Redd counting is an integral part of most Fishery Officers duties. The number and distribution of salmonid redds throughout salmonid catchments provides invaluable information on the range and extent of spawning by both salmon and sea trout. A project was initiated by the Fisheries Science and Management Team of Central Area, North West Region in England in liaison with the Flood Defence function. The main objective of this project was to assess redd count data for Central Area and attempt to quantify these data in order to produce a grading system that would highlight key salmonid spawning areas. By showing which were the main areas for salmon and sea trout spawning, better informed decisions could be made on whether or not in-stream Flood Defence works should be given the go-ahead. The main salmonid catchments in Central Area were broken into individual reaches, approximately 1 km in length. The number of redds in these individual reaches were then calculated and a density per lkm value was obtained for each reach. A grading system was devised which involved looking at the range of density per km values and dividing this by five to produce 5 classes, A - E. A sixth class (F) was used where the density per Ion value was 0.00. This grading system was calculated at two levels of detail. Grades for salmon and sea trout were produced for each individual catchment and also on an Area-wide level. Maps were produced using a range of colours to represent the grade for each reach. These maps provide a highly useful overview of the status of salmonid spawning for each catchment over individual years and highlight the key salmon and sea trout spawning areas in each catchment. These maps and the associated summary data should now provide Flood Defence and Fisheries staff with a fairly detailed overview of the status of spawning in any location within the. main salmonid catchments in Central Area. Although these maps are very useful they should only be used as a guide. The current practice of consulting with the local Fishery Officer should be continued to ensure that expert local knowledge is taken into account.

    Description: This report summarises the findings of a series of electric-fishing surveys carried out at four sites on the River Ribble from September 1997 to September 1998. The aims of these surveys were to assess the impact on juvenile salmonids of a pollution incident involving Synthetic Pyrethrin (SP) that occurred near High Birkwith I (SD 802 767) in September 1997.One of these sites was 2.65km upstream of the pollution whilst the remaining three were at varying distances downstream. Data was collected during surveys of the River Ribble in 1992, 97 and 98. The 1997 and 1998 surveys were carried out specifically to monitor for any possible effects of the SP discharge.Data are shown as grades derived from the National Fisheries Classification scheme (NFC). Results are given for the four salmonid life stages; 0+ trout, 〉0+ trout, 0+ salmon, 〉0+ salmon and also Total Salmonids.

This report looks at the survey carried out by the South Mersey Ecology Team prior to routine deweeding operations on the main River Gowy at the end of July, 1995. The survey covered Flood Defence Stretch References RGOW03 to RGOW16. These stretches were further divided into a series of 43 stretches, each one being approximately 500m in length for ease o f mapping by Ecology. Recommendations for each length have been cross-referenced with the Bill of Quantities where possible, e.g. retention o f margins. In Flood Defence stretch RGOW03, the South West Winter Wetland forms an important habitat for birds. In stretches RGOW04 to RGOW05, the Gowy Meadows and Ditches have been designated a Grade A, Site of Biological Importance, by Cheshire County Council due to the nature of the acidic grassland and diverse ditches. In stretches RGOWIO to RGOW11 the left bank forms Hockenhull Platts, Grade A Site of Biological Importance and County Trust Reserve. In stretches RGOW15 to RGOW16, the area from Mill Farm to the Shropshire Union Canal is a Grade A Site of Biological Importance. These sites are very sensitive and detailed recommendations for working practices can be found in the relevant sections o f the survey.

    Description: This is the NRA's role in wetland conservation report produced by the National Rivers Authority in 1995. This document is the third of a series of three R&D Notes produced as part of an integrated research programme addressing aspects of the NRA's role in wetland management and conservation. Chapter 1 considers the nature of the wetland resource and its definition. Chapter 2 presents the NRA's current legislative and policy framework relating to its role in wetland conservation. National and international legislation and agreements are considered, and particular attention is afforded to the potential implications of the 'Habitats Directive'. Chapter 4 presents key examples of operational casework involving wetlands. Differences in approach and external perceptions of the NRA's current and likely future role in wetland conservation are discussed within Chapter 5. Other issues highlighted in this report are: policy guidance required on NRA’s role in land drainage; standard of flood defence service for wetlands; cost-benefit analysis; strategies for halting and reversing the decline and degradation of wetland resource; and Catchment Management Planning.

    Description: This is the Cheshire stillwaters. Summary results of September 1998 from the Environment Agency, 1998. In May 1997, a Stillwaters meeting was held to discuss the way forward in stillwaters monitoring. It decided upon the establishment of a three year rolling programme, in which three stillwaters would be monitored three times a year, every third year. Oak Mere, Tatton Park Mere and Hatch Mere were surveyed between the 29th - 30th September as part of the three year rolling programme. Betley Mere, Petty Pool, Scotman's Flash and Pearson's Flash were also surveyed. Surveys also included algal and zooplankton samples, which are to be analysed by APEM and presented in the end of year report. The section on results contains information about water column profile; and nutrients (chlorophyll a; Phaeophytin; Nitrate and Nitrite; Ammonia; ortho-Phosphate; Silicate; and total Phosphorus).

    Description: This is the Cheshire Meres 1994 November surveys report produced by the National Rivers Authority in 1995. The report focuses on some of Cheshire meres, which were showing evidence of increasing eutrophication, commonly due to anthropogenic inputs. Concern for the deterioration of the water quality of still waters has been translated by incorporating these priorities into the NRA North West Regional Environmental Strategy for Stillwaters. The meres were also being investigated as possible polluted waters under the EC Nitrate Directive.The ultimate aim is to formulate lakes management options in order to help preserve North West still waters and minimise future restoration programmes. For such pro-active work to be carried out, sufficient background data must be available. It should then be possible to fully assess the current status of these lakes, identify seasonal trends and detect significant point/diffuse pollution inputs. These surveys were the first of a series, and it was intended to repeat similar surveys in Summer and Autumn 1995, and include a further 20 meres.

This report identified key rare and nuisance species of interest to the NRA and prioritised research needs to develop conservation strategies for these species. The NRA has in the past adopted a habitat maintenance and protection approach to conservation paying less attention at individual species. There is a risk that conservation based on a habitat management policy will no further the conservation of certain species. In addition, certain ‘nuisance’ species cause problems for conservation by having a negative impact on more valued species or ecosystems. Through the combination of the review of current legislation and literature and consultation with NRA staff, this project identified key rare and nuisance species of interest to the NRA and prioritised research needs to develop conservation strategies for these species.

This report is focused on the Phase 1 of the Species Management in Aquatic Habitats, based on the Development of priority lists of rare and nuisance species for the National Rivers Authority (NRA). Certain ‘nuisance’ species cause problems for conservation by having a negative impact on more valued species or ecosystems. This project was initiated as part of a programme of research to develop strategies for the management of both rare and nuisance species. This project identified key rare and nuisance species of interest to the NRA and prioritised research needs to develop conservation strategies for these species. A combined provisional list of almost a thousand rare species, a priority list of 58 species of potential interest and a priority list of nine nuisance species was developed by a process of literature review and from suggestions by NRA conservation staff.

    Description: The value of the natural resources of the White River Basin (Basin), AR isrecognized by the area's designation as a "Wetland of International Importance". TheBasin constitutes one of the Nation's largest remaining intact forested wetlandlandscapes, second only to the Atchafalya Basin. It supports the North Americancontinent's largest concentration of over-wintering mallard ducks, a world-class troutfishery, the last vestige of a big river fishery remaining in the Mississippi River Basin,and numerous threatened and endangered species. The continued viability of thiswetland ecosystem depends on the suitability of the hydrologic environment to theresident flora and fauna. Numerous modifications of the Basin hydrologic features in thepast century have seriously impaired the sustainability of these resources. The Basinwidealterations of hydrologic processes (e.g., impoundment and regulatory releases offlows and volumes in the upper reaches, navigational modifications of lower reaches, andconsumptive demands for agricultural use throughout) have affected the hydrology of thesystem profoundly. The result is highly regulated flows and stages, vastly alteredhydrologic patterns, over-stabilized water levels, and disruption of seasonal waterdistribution patterns. Given the critical nature of hydrology in regulating the structureand function of wetland ecosystems, the impacts have been devastating, particularly tothe critical bottomland hardwoods that support the Basin's fish and wildlife resources.To date these piece-meal, system-wide, hydrologic alterations have cornmutativelydegraded the habitat value of this resource for fish and wildlife in the Basin, and havelead to changes in their numbers and distributions. In spite of the enormous stakesinvolved, there has been no comprehensive characterization of the Basin hydrology.System alterations such as channel deepening, dam construction, water allocationplans, and flood control measures are currently pending. These projects will potentiallyhrther modify the hydrologic environments of the Basin, and no doubt require mitigationmeasures. In addition, there is genuine interest in restoring aspects of the Basin's historichydrologic regime within some set of reasonable limits. In order to proceed with thiseffort, the anticipated effects of these modifications and restorations on the Basin ecologyrequire thorough study of the area's historic hydrology, so that connectivity among Basinprecipitation patterns, flow fluctuations, and land use changes can be made. A basinhydrologic characterization is an initial component of this effort. The focus of this effortwas to determine and assemble the data set from which characterization of the hydrologicenvironments of the Basin using historic and recent water level, flow, (primarily byUSGS-WRD) at locations throughout the Basin could proceed.

    Description: Loxahatchee can be grouped into three zones according to the patterns of change of treeislands observed from 1950 to 1991. 1 ) the edge ofthe refuge adjacent to the canals, 2) the eastern interiorof the refuge, and 3) the western interior ofthe refuge. The general trend is for tree islandsAlong the edge of the refuge to have decreased insize, number, and percent cover, while those on theinterior increased in size, nunber, and percentcover.Results from this study illustrate the importanceof flow magnitude as well as hydroperiodand depth in stucturing patterns of tree islandswithin this peat wetland. Restoration of historichydroperiods and depths without historic flow patternsmay not be sufficient to restore or maintainthe historic pattern and function of the system. (60 pages)

    Description: We present a new modeling method for use in large-scale physical systems, such as the Everglades ecosystem.The current work that has been done in the ATLSS (Across-Trophic-Level System Simulation) project-whichfocuses on simulating key Everglades system components-relies on code integration. While this represents anecessary first step in analyzing the dynamics of species within the Everglades, it falls short of true modelintegration. We have constructed a methodology called object-oriented physical modeling (OOPM), which allowsa comprehensive knowledge representation to be constructedfor large-scale systems. OOPM enforces theidea that an implementation ofcomputer code can be accomplished in an incremental fashion by starting with aconceptual model and progressing to more detailed models. During this evolutionary procedure, a minimal amountof code is written, since the emphasis is on developing the conceptual model so that it not only represents theintuitive aspects ofthe model, but is also executable. OOPM provides a kind of "blueprint" for ecologists, biologistsand hydrologists to communicate and integrate models effectively. (14 page document)

    Description: This report describes and summarizes the results from a state-wide survey of Floridaresident saltwater anglers. The survey was designed to provide estimates of the economic valueanglers place on marginal changes in management of selected near-shore marine species.The Contingent valuation method was used to elicit angler willingness to pay for changesin management for redfish, seatrout , mullet, sheepshead, pompano. and king mackerel.Contingent valuation is a process in which respondents are presented with a detailed scenario thatdescribes an opportunity to express their willingness to pay for a proposed change in currentconditions. The process consists of three parts. First. the change in current conditions, or the"good" to be valued is described. Second, the payment method is described. The paymentmethod is usually closely related to typical methods of buying goods similar to the one to bevalued. Finally. the respondent is asked how much they would pay for the good described inthe scenario. A special saltwater fishing license stamp that would allow the holder to takeadvantage of the described management change was used as a payment mechanism. (PDF contains 147 pages.)

    Description: Work has begun on studying the factors responsible for productivityin the Florida springs, which are nearly constant temperature, constantchemical, steady state giant laboratories. Progress has been made on fiveaspects: qualitative description, quantitative description, completionof knowledge of chemical factors, measurement of productivity , developmentof productivity theory.Measurement of the primary productivity in Silver Springs and GreenCove Springs by two new methods: the raising of organisms in cages, and themeasurement of night & day differences in oxygen downstream agree roughly.Production in these springs is greater than previous production figures reportedfor marine, fresh water, and land areas. Instantaneous measures of production show large variations with season, time of day, cloud cover. Productionestimates range from 11,000 lbs per acre per year to 70,000 lbs. glucose peracre per year during daylight hours.Essential stability of the springs environment has been shown withrespect to temperature, phosphorus, and plant cover. A correlation of speciesnumber with lack of stability has been shown with insects. Quantitativestudies have shown very large plant base to pyramids of mass. Correlationof marine invasion with chlorinity has been shown. The essential aspects ofpH regulated phosphorus geochemistry in Florida have been outlined. Sometheoretical ideas on productivity have been evolved. Mapping of sessileorganisms in springs and taxonomic identification of dominants are halfcompleted. Plans for second six months include measurement of herbivoreand carnivore production rates and completion of food chain efficiencydeterminations in Silver Springs as a preparation for subsequentcomparisons between springs.

    Description: The effect of productivity on species variety has been studied by countsof diatom species on glass slides at favorable and unfavorable stations withinSilver Springs. Species variety has been presented in a measure that is independentof sample size, "species per cycle". This measure is based on the linear increase of accumulated species with logarithmic increase of individuals counted, which has been found approximately true for many kinds of populations in many communities. Diatom productivity was measured by the rate of chlorophyll accumulation. The poor station accumulated diatoms and chlorophyll slowly and was characterized by a large species variety. There was little change after 79 days. The rich station accumulated diatoms and chlorophyll rapidly and was characterized by a small species variety that decreased for 93 days as the density of the population increased. These results indicated that species variet was decreased by conditions of high productivity possibly through the action of high densities and competition.Twelve new diurnal production curves were obtained including two more on Silver Springs and one each for 10 different Florida Springs. A shallow oligohaline spring possessed the highest productivity of 58.0 gm/m2/day; a shaded and anerobic spring possessed the lowest producvitiy of 0.66 gm /m2/day. Findings in further studies in Silver Springs indicated a two fold diurnal chlorophyll fluctuation in the pseudoplankton going downstream, photosynthetic quotients corresponding to carbohydrate production on winter or heavily clouded days, and higher quotients corresponding to protein production on sunny, summer days; evidences that bell jar estimates of respiration in flowing water communities lead to underestimates; recalculation of mean depth of plant beds leads to a 5% estimate of photosynthetic efficiency for Silver Springs (rather than 8%). Correlated with a 20% decrease in the discharge associated with widespread drought in 1954-55 the oxygen of the main boil dropped from 2.5 ppm to 1.7 ppm. A production measurement by the diurnal oxygen and carbon-dioxide curve method was made in a somewhat isolated "boat basin." Efficiency of production in this stationary, plankton containing water of Silver Springs origin was about 1%. Further evidence was obtained of nitrate increase in water flowing from anaerobic springs over blue-green algae. The area based chlorophyll of the benthic Silver Springs community was similar to that in forests and lakes of Europe. (63 pages)

    Description: The recreational boating industry is an important component of Florida's economy. Previous Florida Sea Grant College supported research has documented this economic importance to the state's economy in 1980 (see Milon and Riddle, 1983, and Milon et al. 1983). Since that initial research, the manufacturing, retailing, and service sectors comprisingthe industry have continued to grow and prosper as the state's resident and tourist populations increased. This report is an update on the economic significance of the recreational boating industry in Florida since 1980 based on economic indicators of change within the industry. (21pp.)

    Description: Florida Sea Grant, having been involved in the developnent of the Florida soft crab fishery since 1978, decided that an evaluation of the status of this fishery was necessary to determine to what extent Sea GrantExtension activities would be needed to further its development. To that end, this author, in cooperation with Florida Sea Grant marine extension agents and specialists, conducted a survey of the 1983 soft crab producers.Out of 28 identified blue crab shedding operations known to be producing soft shell crabs in 1983, 22 (78.6%) cooperated in filling out a fishery questionnaire which included sections describing their shedding facility,harvest methods, product types, production and sales data, and production costs. The reminder of this paper will be the findings of that survey. (12pp.)

    Description: Nearest-neighbor analyses have been used with mapped data f or tests of spatial dispersion and association i n plant and animal ecology. This paper full describes a computer software package developed to use MonteCarlo trials instead of chi-squared distributions for assigning probabilities to observed values of nearest neighbor statistics. The program can factor-out the unique geometry of resources in a sample plot,which can affect locations of animals, thus testing for direct patternsamong the animals independent of their resource patterns. The Kappa statistic for association is a1 o calculated a1though its application has met with limited success. A users manual and the Fortran program languageis included. (80pp.)

    Description: A small but valuable live bait shrimp fishery has existed in Biscayne Bay since at least the early 1950s. In recent years there has been increasing pressure from recreational fishing and environmental groups to eliminate this fishery from the Bay because the fishing activity is generally thought to be deleterious to the environment and/or destructive to juvenile game fish.This study was initiated to update the existing knowledge of the bait shrimp fishery in Biscayne Bay and document historical trends in number of participants, fishingmethods, fishing area, seasonality, total catch, catch-per-unit-effort, disposition of the catch, and economics of the industry.

    Description: Shrimp melanosis, commonly known as 'blackspot' is aharmless but objectionable surface dicoloration caused bypolyphenoloxidase enzyme systems which remain active duringrefrigeration or ice storage. In the early 1950's sulfitingagents, particularily sodium bisulfite was first introduced to prevent or inhibit melanosis, thus yielding a more valuable harvest (1). Such use of sulfites was 'prior sanctioned1 by the U.S. Food and Drug Administration (FDA) in 1956 (2). More recent FDA decisions reaffirmed this practice, (3) but continuing regulatory scrutiny could restrict or eliminate the application of sulfite on shrimp. The regulatory action is prompted by an increasing concern for adverse 'allergic' reactions most common amongst hyper-(sulfite) sensitive asthmatics. Thus work was initiated to find alternatives to replace or reduce the amount of sulfites required to inhibitshrimp melanosis. This work would screen for possiblealternatives which would require subsequent verification with field tests and statistical evaluations. (21pp.)

    Description: The critical need to predict the turbidity in water due to fine-grained sediment suspensionunder wave action over mud deposits for sedimentation and erosion studies, as well assorbed contaminant transport, is well known. Since fall velocities of fine sediment particlesare very small, they can be easily transported by hydrodynamic flows such as waves andcurrents. The presence of these particles in the water column affects accoustic transmission,heat absorption and depth of the eutrophic zone (Luettich et al., 1989). Because these sedimentsalso have a strong affinity for sorbing nutrients and toxic chemicals, sediments whichhave been deposited on the bottom may function as a source of contaminants to the watercolumn if they are disturbed by eroding forces resulting, for instance, from wave action. Anoutstanding example of a water body for these problems is Lake Okeechobee, the largestshallow lake in Florida. This lake shows typical signs of artificial eutrophication mainly dueto increased phosphorus loading associated with the surrounding region. Resuspension of sediment at the bottom of Lake Okeechobee composed of fine-grainedmaterial has been examined. A sediment transport model was used to simulate likelytrends in the evolution of the vertical suspended sediment concentration profile resultingfrom wave action, and the corresponding eroded bed depth was calculated through massbalance. Requisite information on characteristic parameters and relationships related tofine sediment erodibility were derived from field sampling of bottom sediment in the lake,and through laboratory experiments using this sediment and lake water.

    Description: Marine fisheries in Florida encompass 109 finfishes andinvertebrate species, reflecting the state's diversity of coastaland ocean habitats. Management of Florida's valuable fisheriesnecessarily entails forecasting fluctuations in fished stocks.By understanding recruitment, the processes that result in thesurvival of fishes from early life history to the adult or exploitedstage, management potential can be improved. Respondingto an interest in recruitment expressed by Florida's academicscientists, the Florida Sea Grant College Program, in conjunctionwith the Florida Chapter of the American Fisheries Society,organized the workshop at Live Oak to determine the usefulness ofunderstanding recruitment, the likelihood of success and themechanism for proceeding.The document represents the collectivewisdom of many of Florida's leading scientists. It is designedto provide guidance for strategic planning in future fisheryresearch and management activities. (69pp. Keppel and Seaman (eds)

    Description: The Cabo Rojo Salt Flats, at the southwestern tip ofPuerto Rico, provide important autumn stopover and winteringhabitat for migratory shorebirds. I studied the abundanceand distribution of shorebirds and their food resources atthis site during autumn of 1990 and 1991.Small calidrids (primarily Calidris pusilla and C.mauri) were the most abundant shorebirds at the salt flats.The maximum weekly counts of small calidrids in 1990 (2,690)and 1991 (3,532) occurred in mid October. Calidrids foragedprimarily in the Fraternidad lagoon system; roosting tookplace most often at the neighboring Candelaria Lagoon.The macroinvertebrate prey important to calidrids in theFraternidad system were Dasyhelea (Diptera), Trichocorixa(Hemiptera), and Artemia (Anostraca). Changes in invertebrateabundance coincided with fluctuations in salinity. (100 page document)

    Description: West Indian manatees (Trichechus manatus) occur throughout the year inrivers, estuaries and coastal areas of Florida (Moore 1951, Hartman 1974,Irvine and Campbell 1978, Irvine et al. 1981). Manatees are widely dispersedalong the Gulf and Atlantic Coasts of the southeastern U.S. during the summermonths and aggregate at traditional warm water wintering sites during coolermonths (Hartman 1974, Powell and Waldron 1978, Rose and McCutcheon 1980,Rathbun et al. 1982, Powell and Rathbun 1983, Shane 1983). Their winterrange on the east coast of Florida extends as far north as Jacksonville(Hartman 1974, Rathbun et al. 1983, Kinnaird and Valade 1983) but manateesare sighted most frequently in the northeastern region of the peninsuladuring the summer months (Moore 1951, Hartman 1974, Irvine and Campbell1978). Recent evidence suggests that manatees in northeastern Florida arenot discrete subpopulations and that manatees make seasonal north/southmigrations along the eastern coastal waterways (Hartman 1974, Shane 1983,Rathbun et al. 1983, Kinnaird and Valade 1983).Northeastern Florida has the highest known manatee mortality in thestate, including the highest incidence of deaths due to collisions withboats, particularly in the St. Johns River and Brevard County (O'Shea et al.in prep.). It is difficult to develop wise management policies for thisregion because spatial and temporal use of northeastern Florida by manateeshas not been fully documented. The nature and extent of boat traffic alsohas not been described. I conducted aerial surveys for one complete year over the lower reachesof the St. Johns River and the northeastern section of the ICW (southernVolusia County to Kings Bay, Georgia) to document the spatial and temporalpatternLt~at characterize manatee use of northeast Florida, and to describethe nature and extent of boat traffic. The development of managementpractices based on these patterns should help minimize resource conflicts andpossibly reduce manatee boat/barge mortality. (60 page document)

    Description: This report documents breeding numbers, reproductive success, and foragingdispersion of long-legged wading birds in the Water Conservation Areas (WCAs) of theEverglades during the first six months of 1993. Briefly, the 1993 spring had abnormallyhigh water and windy conditions throughout the season, and produced poor nesting effort,low to moderate nesting success, and low production of young. Some species, like WoodStorks and White Ibises, did not nest at all in the WCAs. Others, like Great Egrets andTricolored Herons, showed considerably tenacity under the extremely poor nestingconditions. The 1993 season provided a rare chance to record the reproductive responses ofwading birds during sustained high water conditions. (108 page document)
