    An evaluation of the Investors in People Standard (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Human resource management journal 7 (1997), S. 0 
    Details
    ISSN: 1748-8583
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: The authors describe the Investors in People Standard and explain the process which organisations need to complete to gain the accolade Investor in People. A postal survey with 455 respondents is described and findings given. A total of 17 case studies were also conducted, as were seven interviews with key agencies in this field. The authors conclude that there is evidence of positive perception of the impact of human resource development (HRD) on organisational performance and that there is a common acceptance of certain strategies as best practice. There is also evidence that the adoption of a systematic process to adjusting training and development to business strategies results in a more normative commitment to employee development.

    Vegetation and soil recovery in wilderness campsites closed to visitor use (1986)
    Springer
    Environmental management 10 (1986), S. 375-380 
    Details
    ISSN: 1432-1009
    Keywords: Vegetation recovery ; Soil recovery ; Wilderness campsites ; Sequoia National Park ; Recreational impacts
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Recreational use of wilderness results in impacts to vegetation and soil in trails and campsites. Traditionally, campsite impact studies have compared campsites receiving various levels of use with unused control areas. Field studies in Sequoia National Park, California, indicate that the degree of impact to vegetation and soils also varies within campsites. The central areas of campsites, where trampling is concentrated, show lower plant species diversity, differences in relative species cover, more highly compacted soils, and lower soil nutrient concentrations than do peripheral, moderately trampled, and untrampled areas within the same campsite. Three years after closure to visitor use, the central areas show less increase in mean foliar plant cover, and soils remain more highly compacted than in previously moderately trampled areas of the same sites. Changes in relative species cover over time are used to assess both resiliency to trampling and species composition recovery within campsites closed to visitor use.

    Evaluating wilderness recreational opportunities: Application of an impact matrix (1992)
    Springer
    Environmental management 16 (1992), S. 397-403 
    Details
    ISSN: 1432-1009
    Keywords: Recreational opportunities spectrum ; Crowding ; Carrying capacity ; Impact matrix ; Campsite evaluation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract An inventory of the severity and spatial distribution of wilderness campsite impacts in Sequoia and Kings Canyon National Parks identified a total of 273 distinct nodes of campsites or “management areas.” A campsite impact matrix was developed to evaluate management areas based on total impacts (correlated to the total area of campsite development) and the density, or concentration, of impacts relative to each area's potentially campable area. The matrix is used to quantify potential recreational opportunities for wilderness visitors in a spectrum from areas offering low impact-dispersed camping to those areas offering high impact-concentrated camping. Wilderness managers can use this type of information to evaluate use distribution patterns, identify areas to increase or decrease use, and to identify areas needing site-specific regulations (e.g., one-night camping limits) to preserve wilderness resources and guarantee outstanding opportunities for solitude.

    Natural fire management in National Parks (1986)
    Springer
    Environmental management 10 (1986), S. 21-24 
    Details
    ISSN: 1432-1009
    Keywords: Fire history ; Fire management ; Natural fire ; National Park Service ; Resource management policy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract An evolving understanding of ecological processes, together with ambiguities in National Park Service policy, have led to multiple interpretations of the role of management in our large natural area National Parks. National Park Service management policies must be dynamic and responsive to changes in scientific knowledge and societal values. We propose that the principal aim of NPS resource management in natural areas is the unimpeded interaction of native ecosystem processes and structural elements. The case of the changing role of natural fire management is used as an example in developing this rationale.

    Effects of herbage removal on productivity of selected high-sierra meadow community types (1989)
    Springer
    Environmental management 13 (1989), S. 485-491 
    Details
    ISSN: 1432-1009
    Keywords: Grazing ; Sierra Nevada ; Stock use ; Subalpine meadows
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract We investigated the effects of herbage removal on three subalpine meadow plant communities in the Rock Creek drainage of Sequoia National Park, California, USA. In the xericCarex exserta Mkze. (short-hair sedge) type, annual aboveground productivity averaged 19 g/m2 in control plots (clipped once after plant senescence in late September) over a five-year period. Annual aboveground productivity was enhanced about 30%–35% when plots in this community type were clipped more frequently (i.e., “additional” herbage removal in the early, mid, and late seasons) during each of four treatment years but was reduced by 13%–19% during a fifth (recovery) year in which all but late September clipping was suspended. In a moderately mesicEleocharis pauciflora (Lightf.) Link. (few-flowered spike rush)-Calamagrostis breweri Thurb. (short-hair grass) type, control plot productivity averaged 115 g/m2/yr and was reduced by 20–30% by the additional herbage removal. A more mesicDeschampsia caespitosa (L.) Beauv. (tufted hairgrass)-Carex rostrata Stokes, (beaked sedge) type had the greatest mean above-ground productivity (169 g/m2/yr) but also showed damage (i.e., decrease in productivity by 15%–20%) caused by the additional herbage removal. These data suggest that longterm, intensive herbage removal may be more detrimental to moderately mesic and mesic subalpine meadow community types than to xeric types.

    Establishing backcountry use quotas: An example from Mineral King, California (1981)
    Springer
    Environmental management 5 (1981), S. 335-340 
    Details
    ISSN: 1432-1009
    Keywords: Use restrictbns ; Trailhead quotas ; Backcountry carrying capacities ; Permit use data
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Increasing levels of visitor use and consequent resource damage have necessitated that backcountry use restrictions be established in the Mineral King area of Sequoia National Park, California. In this paper we review the steps taken in developing a trailhead quota system. The availability of acceptable campsites, based on a detailed inventory of site distribution and impact, was used to quantitatively derive use capacities for each camp area. Wilderness permit data on visitor dispersal patterns from the major trailheads, including length of stay at each camp area, were then used to translate the area capacities into daily trailhead quotas that would assure that these capacities were not surpassed. The general approach is applicable to any backcountry area, although large complex areas may require the use of available computer simulation models.

    Wilderness permit accuracy: Differences between reported and actual use (1982)
    Springer
    Environmental management 6 (1982), S. 329-335 
    Details
    ISSN: 1432-1009
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Wilderness permits are valuable tools for recording backcountry use patterns. They provide a valuable basis upon which management decisions are made. Unfortunately, significant inaccuracies in reporting permit data result from noncompliance, transmission errors, and changes in visitor plans. Data from Sequoia and Kings Canyon National Parks in California show that in 1978, 97 percent of the parties obtained wilderness permits. Changes in visitor plans resulted in an over-reporting of total persons by 8 percent and of visitor nights by 23 percent. The latter was due primarily to shortening of trip length. Over-reporting was greatest when permits were issued well in advance of the trip. Backcountry managers should be aware of possible inaccuracies in permit data and may want to adjust for them under certain circumstances.
