Vitals Rates And Seasonal Movements Of Two Isolated Greater Sage-Grouse Populations In Utah's West Desert, Jason D. Robinson, Terry A. Messmer Jan 2013

Vitals Rates And Seasonal Movements Of Two Isolated Greater Sage-Grouse Populations In Utah's West Desert, Jason D. Robinson, Terry A. Messmer

Human–Wildlife Interactions

Declines in greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) populations in Utah over the last century parallel range-wide trends. However, little is known about the ecology of sage-grouse populations that inhabit Utah’s naturally fragmented habitats. Utah’s West Desert sage-grouse populations occupy sagebrush (Artemisia spp.) habitats that are geographically separated by the Great Salt Lake, and largely confined to the Sheeprock and Deep Creek watersheds. From 2005 to 2006, we monitored sage-grouse that were radio-collared in each watershed to determine the factors affecting the vital rates in these isolated populations. Livestock grazing by domestic cattle was the dominate land use ...


Livestock Predation By Common Leopard In Binsar Wildlife Sanctuary, India: Human-Wildlife Conflicts And Conservation Issues, Chandra Prakash Kala, Kishor Kumar Kothari Jan 2013

Livestock Predation By Common Leopard In Binsar Wildlife Sanctuary, India: Human-Wildlife Conflicts And Conservation Issues, Chandra Prakash Kala, Kishor Kumar Kothari

Human–Wildlife Interactions

We investigate livestock predation by the common leopard (Panthera pardus) and emerging conflicts between this species, local people, and wildlife authorities at the Binsar Wildlife Sanctuary in the Himalayan region of India. We scrutinized secondary data that were collected by wildlife authorities; we also conducted informal interviews of villagers living within sanctuary, and wildlife staff to understand various human–leopard conflicts. Leopard density was approximately 0.33/km2 in the sanctuary. Leopards killed 1,763 domestic animals, about 90% of which were cattle, during a 14-year period. Within the sanctuary, leopards killed 1 person and injured 9 others. This high ...


Winter Habitat Use By Juvenile Greater Sage-Grouse On Parker Mountain, Utah: Implications For Sagebrush Management, Danny Caudill, Terry A. Messmer, Brent Bibles, Michael R. Guttery Jan 2013

Winter Habitat Use By Juvenile Greater Sage-Grouse On Parker Mountain, Utah: Implications For Sagebrush Management, Danny Caudill, Terry A. Messmer, Brent Bibles, Michael R. Guttery

Human–Wildlife Interactions

Greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) are entirely dependent on sagebrush (Artemisia spp.) for food and cover during winter. Loss or fragmentation of important wintering areas could have a disproportionate affect on population size. We radio-marked and monitored 91 juvenile sage-grouse in south-central Utah from 2008 to 2010. Thirty-four individuals survived to winter (January to March) and were used to evaluate winter habitat use. Resource use was calculated using kernel density estimation of radio-marked individuals and compared to available habitat using a G-test. We found that juvenile sage-grouse used winter habitats characterized by 0 to 5% slopes regardless of aspect ...
