Greater Sage-grouse natal dispersal and brood augmentation with captive-reared chicks
In response to population declines, recent research on greater sage-grouse (Centrocercus urophasianus) has focused on the population ecology, habitat relationships, and response to management practices by this species. However, the mechanisms,…
Development of landscape scale resource selection models for the management of Gunnison sage-grouse in the Gunnison Basin population
Gunnison sage-grouse (Centrocercus minimus) have declined substantially from their historica range and were listed as threatened by the U. S. Fish and Wildlife Service in November of 2014. GUSG are distributed into seven isolated populations in…
Gunnison sage-grouse captive-rearing
Gunnison sage-grouse (Centrocercus minimus, hereafter GUSG) is a species of concern in Colorado. Two conservation issues addressed in the Gunnison Sage-grouse Rangewide Plan (RCP) are the population persistence of GUSG (especially the small…
Greater sage-grouse research in the Parachute-Piceance-Roan Region of western Colorado. Part I: assessment of greater sage-grouse response to pinyon-juniper removal
Large-scale changes to sagebrush habitats throughout western North America have led to growing concern for conservation of greater sage-grouse (Centrocercus urophasianus) and repeated petitions to list the species under the Endangered Species Act.…
Foraging ecology of nonbreeding ducks and other waterbirds in the South Platte River Basin
Attracting and holding large populations of waterfowl are goals of habitat management for nonbreeding waterfowl. Currently, many habitat planners use bioenergetics approaches to guide habitat planning for nonbreeding waterfowl and shorebirds. In…
Columbian sharp-tailed grouse chick and juvenile radio transmitter evaluation
The Columbian sharp-tailed grouse (CSTG, Tympanuchus phasianellus columbianus) is one of six subspecies of sharp-tailed grouse in North America. CSTG currently occupy 10% of their former range due to habitat loss. Since the initiation of the…
Comparative recruitment rates of mountain plovers (Charadrius montanus) in eastern Colorado
The mountain plover (Charadrius montanus) is a migratory shorebird which breeds on the shortgrass prairies of Colorado, Wyoming, and Montana. Continental population trends suggest a steady decline over the past century. Colorado is considered the…
Raptor data integration, species distribution, and suggestions for monitoring
Where they exist, raptor monitoring databases have generated important insights into various aspects of raptor ecology, and can provide a sound foundation for specific management priorities for individual species or within the larger context of…
Pilot study to evaluate avian response to conservation reserve program mid-contract management practices in northeastern Colorado
The Conservation Reserve Program (CRP) is a government program in which landowners are paid to maintain grass cover on land that was, and would otherwise be, used for row-crop agriculture. Overall, the CRP has had many documented benefits to…
Using GPS satellite transmitters to estimate survival, detectability on leks, lek attendance, inter-lek movements, and breeding season habitat use of male greater sage-grouse in northwestern Colorado
Implementing effective monitoring and mitigation strategies is crucial for conserving populations of sensitive wildlife species. Concern over the status of greater sage-grouse (Centrocercus urophasianus) populations has increased both range-wide and…
