Sage-Grouse and Indirect Interactions: Potential Implications of Coyote Control on Sage-Grouse Populations
Coyotes (Canis latrans) are lethally controlled throughout the range of Greater Sage-Grouse (Centrocercus urophasianus) and it has been suggested that such control may benefit sage-grouse. However, the perceived benefits of control are based on the direct effects of coyotes on sage-grouse and largely ignore potential indirect interactions. Here, we summarize some of the evidence for direct effe...
متن کاملConsiderations for Sage-Grouse Management Objectives
In March 2010, the U.S. Fish and Wildlife Service (FWS) identified the greater sage-grouse (Centrocercus urophasianus; sage-grouse) as a candidate species for protection under the Endangered Species Act (ESA) because of habitat loss and fragmentation and that regulatory mechanisms needed to protect the species and its habitat were inadequate. However, after further review of on-going range wide...
متن کاملSage-grouse Nesting and Brood Habitat Use in Southern Canada
Greater sage-grouse (Centrocercus urophasianus) populations have declined from 66 to 92% during the last 30 years in Canada, where they are listed as endangered. We used radiotelemetry to examine greater sage-grouse nest and brood habitat use in Alberta and assess the relationship between habitat and the population decline. We also identified the patch size at which sage-grouse were selecting n...
متن کاملLek Organization in Sage Grouse: Variations on a Territorial Theme
-During a 5-year study of Sage Grouse (Centrocercus urophasianus) in eastern California, displaying males abandoned territoriality throughout one breeding season and did so intermittently in three others. Abandonment followed a severe winter and was correlated with a change from location-dependent to hierarchical dominance relationships between males. Intermittent territorial breakdowns occurre...
متن کاملTHE STATUS OF SAGE GROUSE (Centrocercus urophasianus urophasianus) IN CANADA
The sage grouse (Crentrocercus urophasianus) is the largest North American grouse and depends on sagebrush (Artemisia spp.) for diet and protective cover. The association with sagebrush limits the range of sage grouse to the range of sagebrush. As a result of the loss of native sagebrush-grasslands, the range of sage grouse has decreased by over 50% since the turn of the century. Sage grouse ar...
