Effects Of Mule Deer Grazing On Alfalfa Seed Production, Dennis D. Austin, Philip J. Urness
Effects Of Mule Deer Grazing On Alfalfa Seed Production, Dennis D. Austin, Philip J. Urness
Great Plains Wildlife Damage Control Workshop Proceedings
Evaluation of crop loss caused by mule deer (Odocoileus hemionus) grazing on alfalfa grown for seed harvest was studied in northern Utah. Results indicated (1) wire baskets used to protect non-grazed plots did not affect alfalfa production, and (2) alfalfa seed crop loss was directly correlated with alfalfa hay crop loss. Consequently, methods used to evaluate crop loss to alfalfa hay may be applied to alfalfa seed.
Predation Of Big Game And Livestock In The Texas Trans-Pecos, S. Kemble Canon
Predation Of Big Game And Livestock In The Texas Trans-Pecos, S. Kemble Canon
Great Plains Wildlife Damage Control Workshop Proceedings
Predation of livestock and big game remains a matter of concern for ranch managers and operators in the Trans-Pecos. Current evidence indicates that mountain lions (Felis concolor), bobcats (Lynx rufus), and coyotes (Canis latrans) are the primary predators involved, although little information is available on bobcats. A gradual shift from sheep to cattle management has resulted in a corresponding decrease in the intensity of predator control efforts for livestock protection. However, potential lease hunting income has renewed predator control efforts for protection of the 3 primary big game species, pronghorn antelope (Antilocapra americana), …
Wild Ungulate Depredation On Winter Wheat: Effects On Grain Yield, Dennis D. Austin, Philip J. Urness
Wild Ungulate Depredation On Winter Wheat: Effects On Grain Yield, Dennis D. Austin, Philip J. Urness
Great Plains Wildlife Damage Control Workshop Proceedings
The effects of big game grazing of winter wheat on grain yield were studied during 12 trials in northern Utah between 1990-92. Differences in yield were measured for each trial using 20 sets of 1-m2 plots protected and variously grazed by mule deer (Odocoileus hemionus), pronghorn (Antilocapra americana) and Rocky Mountain elk (Cervus elaphus) in a randomized block design along the edges of sampled fields. Plots were hand cut at the beginning of commercial harvest. Grazing impacts were indexed by nighttime counts of game animals, pellet-group counts, and ocular estimates of percent track …
