Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar
Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar
Poverty, Gender, and Youth
This issue of SEEDS focuses on ways in which women have been involved in a government forest conservation and restoration program in Nepal. As is common with many large-scale projects with a general impact, women were not a direct focus of the project's original design. As activities got underway, however, both the Nepali staff and their expatriate colleagues quickly realized that the direct involvement of women was crucial to the success of the project's participatory strategy. Over the initial five years, 1980 to 1985, a number of approaches to addressing women's needs and generating their active participation were tried. The …

Microhabitat Selection And Diel Movements Of Juvenile Rainbow Trout (Salmo Gairdneri) Introduced Into Mid-Elevation Reservoirs In Utah, Wayne A. Wurtsbaugh, Roger Tabor
Microhabitat Selection And Diel Movements Of Juvenile Rainbow Trout (Salmo Gairdneri) Introduced Into Mid-Elevation Reservoirs In Utah, Wayne A. Wurtsbaugh, Roger Tabor
Watershed Sciences Faculty Publications
The distribution and movement patterns of fingerling rainbow trout stocked into reservoirs in Utah were investigated with · SCUBA observations and by vertical gill netting. For several weeks after stocking, fingerling trout (ca. 80 mm standard length) were strongly oriented to the shore, and selected habitats providing cover. During the underwater observations, no fish were seen below depths of 2 meters. Two weeks after stocking, the fingerlings were most abundant under docks near where they were planted, indicating that dispersal was relatively slow. Jacob's electivity indices for natural substrates in water 0-1.5 meter deep were in sand, gravel, cobble, boulders …
Importance Of Predation By Adult Trout On Mortality Rates Of Fingerling Rainbow Trout Stocked In East Canyon Reservoir, Utah, Wayne A. Wurtsbaugh
Importance Of Predation By Adult Trout On Mortality Rates Of Fingerling Rainbow Trout Stocked In East Canyon Reservoir, Utah, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
Personnel from Utah State University, working in cooperation with the Utah Division of Wildlife Resources and the Utah Cooperative Fish and Wildlife Research Unit, are attempting to determine various sources of mortality of fingerling rainbow trout (Salmo gairdneri) stocked into mid-elevation reservoirs in the State. Returns of planted fish are often much below desired levels. Angler surveys indicate that in East Canyon Reservoir, fishermen harvest only about 30% of the fingerling trout stocked, and this is a much higher return than in many other waters.

Harvested And Grazed Lupin Stubbles On Following Wheat South Carrabin., J W. Bowden
Experimental Summaries - Plant Research
Location: South Carrabin lease block
Harvested and grazed lupin stubbles on following wheat. Trial 86M8
This trial is difficult to analyze statistically because of the treatment changes induced by sheep breaking in to some of the plots. Further, lupin grain yields were not very high and so differences between harvested and unharvested treatments are not large. Also the grazing intensity was not very severe (except on the unintentionally grazed plots) and so the effect of grazing is also relatively small.

Evaluation Of New Pasture Legume Species In Terms Of Summer Feeding Value And Effects On Wool Production., S E. Flecker, C W. Thorn, J. B. Rowe, Tess Casson
Experimental Summaries - Plant Research
86KA71, Pasture legumes improve the feeding value of summer pastures in a mediterranean-type environment by maintaining the protein intake of grazing animals over the dry summer period, much of which comes from the ingestion of legume burr (A.D. Wilson and N.L. Hindley, 1968). Some of the most important species of pasture legumes to have been released commercially are Trifolium subterraneum (sub.clover), Medicago truncatula (barrel medic) and Medicago polymorpha (burr medic) (D.B. Purser, G.B. Taylor and W.J. Collins, 1987). What little information is available on the feeding value of these species suggests that barrel medic pod (H. Brownlee, 1973) and dry …
