Mule Deer Diets On A Chained And Seeded Central Utah Pinyon-Juniper Range, United States Department Of Agriculture, Forest Service
Mule Deer Diets On A Chained And Seeded Central Utah Pinyon-Juniper Range, United States Department Of Agriculture, Forest Service
Forestry
Study of the seasonal use by mule deer of some native and introduced species on a pinyon-juniper restoration project showed that woody species made up the bulk of pellet samples, followed by forbs and grasses. Land managers are advised on seeding and grazing practices for enhancing big game habitats.
Response Of Grass Species To Tree Harvesting In Singleleaf Pinyon-Utah Juniper Stands, United States Department Of Agriculture, Forest Service
Response Of Grass Species To Tree Harvesting In Singleleaf Pinyon-Utah Juniper Stands, United States Department Of Agriculture, Forest Service
Forestry
Cover, yield, and nutrient concentrations of grasses were sampled on tree-harvested and nonharvested plots on north, west, and south aspects of a singleleaf pinyon (Pinus monophylla)-Utah juniper (Juniperus osteosperma) stand. Grass cover increased rapidly the first 2 years following tree harvest, but the rate of increase declined over the next 2 years. Grass yield varied among aspects and soil microsites on tree-harvested plots but not on the nonharvested plots where tree competition masked aspect and microsite effects. All grass species had greater yield and greater percentage nitrogen and phosphorus on harvested than on nonharvested plots. Low digestibility of some species …
Soil Water And Temperature In Harvested And Nonharvested Pinyon-Juniper Stands, United States Department Of Agriculture, Forest Service
Soil Water And Temperature In Harvested And Nonharvested Pinyon-Juniper Stands, United States Department Of Agriculture, Forest Service
Forestry
Tree harvesting increased soil water content, but the effect diminished over 4 years. The mean increase in soil water content was 2 to 4 percent the first year following harvest and 0 to 3 percent after 4 years. Although tree harvesting released soil water previously used by tree species, other biotic and abiotic demands increased. We speculate postharvest increases in wind and solar energy at the ground surface and increased understory transpiration in part explain the decline in soil water content differences between harvested and nonharvested plots over time.
Pinyon-Juniper Volume Equations For The Central Rocky Mountain States, United States Department Of Agriculture, Forest Service
Pinyon-Juniper Volume Equations For The Central Rocky Mountain States, United States Department Of Agriculture, Forest Service
Forestry
Gross cubic foot volume equations are now available for pinyon-juniper and several other woodland species in Nevada, Idaho, Utah, Colorado, Wyoming, and South Dakota. The volume equations are based on data collected as a subsample of woodland inventories conducted by Federal and State land management agencies. In these inventories, volumes of 4,705 trees were estimated by a visual sampling method.
