    Notes: The objective of this study was to evaluate seven woody plant species on four growth media for their potential contribution to moose habitat and establishment of viable plant communities on a proposed mine site in southcentral Alaska. Populus balsamifera (balsam poplar), Salix alaxensis (feltleaf willow), S. barclayi (Barclay willow), S. bebbiana (Bebb willow), Alnus tenuifolia (thinleaf alder), Betula papyrifera (paper birch), and Picea glauca (white spruce) were selected for their functions in moose habitat, ease of propagation, and presence in the existing native vegetation. Three native soils were selected for biological characteristics such as different potential to form mycorrhizae and to regenerate local plant species, both of which are governed partly by existing vegetation. The fourth growth medium, glacial till or overburden, was expected to have little or no biological activity. A mining disturbance was simulated on three sites by removing existing vegetation from the plots, stripping the native soils, and then spreading these soil materials over the respective study plots. Rooted cuttings of the Salicaceae and nursery seedlings of the other species were planted in each of the four growth media. Height and survival of all plant species were greater on the three soil media than on the glacial till during the second and third years. Percentage of ectomycorrhizal infection on transplants was similar among growth media, although lower ectomycorrhizal infection occurred on volunteers in grassland soils than in the other growth media. Browsable plants were produced within three years on the disturbed native soils but not on the glacial till.

    Notes: Native grasses may be used for multiple, sometimes conflicting, goals in revegetation projects. Woody plants are frequently desired for moose browse and timber in Alaska, but naturally occurring Calamagrostis canadensis (bluejoint reedgrass) hinders the establishment of these desired species. Seven grass cultivars of Alaskan origin were evaluated for their ability (1) to stabilize the soil, (2) to reduce regeneration of C. canadensis, (3) to allow openings for natural colonization, and (4) to permit establishment of desirable rooted cuttings. Cultivars tested are “Arctared” Festuca rubra (red fescue), “Alyeska”Arctagrostis latifolia (polar-grass), “Nugget”Poa pratensis (bluegrass) “Norcoast”Deschampsia beringensis (Bering hairgrass), “Nortran”Deschampsia caespitosa (tufted hairgrass), “Gruening” Poa alpina (alpine bluegrass), and “Sourdough” Calamagrostis canadensis. These were tested as single species and in multi-species mixtures, with two seeding rates of the multi-species mixture (0.5, 0.25 seeds/cm2). Experimental plots included unfertilized, unfertilized with rooted Salicaceae cuttings, and fertilized (350 kg/ha 20:20:10). A control plot was not seeded. After three growing seasons, Nortran D. caespitosa and Arctared F. rubra were the most successful cultivars. They provided 87% to 98% of the seeded-species cover for soil stabilization and suppressed C. canadensis on the fertilized subplots without reducing species diversity. Gruening Poa alpina was less than 3 cm tall, and it helped stabilize the site without interfering with woody plant establishment. Although cuttings were shorter under some seed treatments compared to the nonseeded control, heights of cuttings were not related to cover of seeded cultivars (r = 0.09, p 〉 0.55) but were positively correlated with total vascular plant cover (r= 0.61, p 〈 0.001).

    Plant growth and ectomycorrhiza formation by transplants on deglaciated land near Exit Glacier, Alaska (1999)

    Notes: Abstract  Ectomycorrhiza (EM) formation on plant roots in successional communities may vary with plant species, plant age, and age of vegetation after disturbance. To evaluate differences in mycorrhizal fungus communities on roots of same-aged seedlings across a deglaciated chronosequence, indoor-grown bioassay plants of four dominant species Epilobium latifolium L. (dwarf fireweed), Populus balsamifera ssp. trichocarpa (Torr.&Gray) Hult. (black cottonwood), Alnus sinuata (Regel) Rydb. (Sitka alder), and Picea sitchensis (Bong.) Carr. (Sitka spruce) were transplanted into five successional stages (Barren, Isolated Plant, Patchy, Alder, and Cottonwood) following deglaciation near Exit Glacier, Alaska. The species were selected for their successional status and mycorrhiza formation potential [EM or arbuscular mycorrhiza (AM) or both]. Seedlings were transplanted in June 1992, and half were harvested at the ends of the two subsequent growing seasons. The EM communities on P. balsamifera differed across the chronosequence while those of the other species did not. Morphotype B dominated the EM on P. balsamifera after the Barren stage, and the greatest EM colonization was in the Isolated Plant and Patchy stages. No AM were found. The EM observed on even-aged seedlings in this study were a subset of the EM found on naturally occurring plants (seedlings to mature trees) in a prior study, and some were common to multiple plant species. Most plant growth responses were not significant across stages or were inconsistent among plant species.

    Use of soil transfer for reforestation on abandoned mined lands in Alaska (1993)

    Notes: Abstract Soil transfers, presumed to contain mycorrhizal fungal inoculum from a native plant community, were applied to rooted cuttings and volunteer plants of Populus balsamifera L. to improve their growth on an abandoned mined site in south central Alaska. The objectives of the study were to determine (1) if these soil transfers could be substituted for additional P fertilizer when applied with a base level of NP fertilizer to improve growth, and (2) if P added to treatments receiving a base level of NP fertilizer and soil transfer would suppress mycorrhizal formation. Physical dimensions of plants were measured near the beginning and end of each of two growing seasons. Several plants per plot were harvested at the end of year 2 to determine mycorrhizal formation, current growth, and leaf nutrient concentrations. Plant height was significantly increased only when soil transfer and additional P treatments were combined. Response to additions of P fertilization alone or soil transfer alone were not significantly different from each other. Current twig growth increased with either treatment alone or both combined. Soil transfer on cuttings resulted in more ectomycorrhizal formation than either the control or additional P. Leaf N concentrations on cuttings and volunteers increased when plants were treated with soil transfer. Similar growth responses were achieved by soil transfers or additional P, but mycorrhizal formation was improved with the soil transfer treatments. P added to the base level plus soil transfer did not suppress or improve mycorrhizal formation compared to that with soil transfer alone.

    Notes: Abstract Soil transfers from an intermediate successional site and a mature forest site were applied to Populus balsamifera L. cuttings and Alnus crispa (Ait.) Pursh seedlings placed on an abandoned mined site in south central Alaska to improve plant establishment. Mycorrhizal fungi in the soil transfers from the two successional stages were hypothesized to have different effects on plant species that colonize disturbed sites at different times or on different substrates. The site consisted of coarse, dry, low-nutrient spoils and was naturally colonized by scattered P. balsamifera but not A. crispa, although seed sources for both were adjacent to the site. Physical dimensions of the transplanted seedlings and cuttings were measured at the beginning and end of each growing season. Selected plants were harvested at the end of the 2-year study and examined for mycorrhizal formation, current growth, and leaf tissue nutrient concentrations. Both plant species were taller when treated with the soil transfers from the mature forest than with soils from the intermediate site although the increase for A. crispa was greater. Physical dimensions, current growth, and nutrient concentrations were greater when A. crispa was treated with the mature soil transfer compared with the intermediate soil transfer. Mycorrhizae which infected Alnus were predominantly a brown woody type, while other types accounted for greater relative mycorrhizal infection percentage on Populus. Insufficient quantities of mycorrhizal inoculum of suitable species, as well as low moisture and low nutrient conditions, may be factors limiting A. crispa colonization on primary disturbed sites in south central Alaska.
