Relationship of Lesser Prairie- Chicken Lek Presence and Density to Grassland Conservation Programs
ثبت نشده
چکیده
Amount of grassland and CRP combined was significantly associated with lek density at multiple spatial scales. This association, however, was not in the predicted direction. Low -density lek points had more surrounding grassland and CRP than did high-density lek points or no lek points. Thus, amount of grassland and CRP alone may not be enough to conserve lesser prairie-chickens; condition of grasslands may be more important.

Review of the Historical and Present Status of the Lesser Prairie-chicken (Tympanuchus pallidicinctus) in Texas
Historically, the lesser prairie-chicken (Tympanuchus pallidicinctus) occurred in sandy rangeland throughout the northeastern and southwestern (Permian Basin) regions of the Texas Panhandle. Analyses of the historical distribution showed a large reduction in the range of the species in Texas between 1963 and 1980 (78% or 1,070,426 ha), particularly in the southwestern and east-central panhandle...
متن کاملEffects of Lek Age on Age Structure and Attendance of Lesser Prairie-Chickens (Tympanuchus pallidicinctus)
—We used data from lesser prairie-chickens captured on leks to test the hypothesis that age structure of attending birds is reflected in lek age (i.e., years of continuous attendance). As leks become older the age structure of attending birds becomes dominated by adults. Average lek size (number of attending males) was not affected by lek age. Establishment of satellite leks (leks # 2 y of cons...
متن کاملResponses of male Greater Prairie-Chickens to wind energy development
Renewable energy resources have received increased attention because of impacts of fossil fuels on global climate change. In Kansas, USA, optimal sites for wind energy development often overlap with preferred habitats of the Greater Prairie-Chicken (Tympanuchus cupido), a lek-mating prairie grouse of conservation concern. We tested for potential effects of energy development on male Greater Pra...
متن کاملDynamic Disturbance Processes Create Dynamic Lek Site Selection in a Prairie Grouse
It is well understood that landscape processes can affect habitat selection patterns, movements, and species persistence. These selection patterns may be altered or even eliminated as a result of changes in disturbance regimes and a concomitant management focus on uniform, moderate disturbance across landscapes. To assess how restored landscape heterogeneity influences habitat selection pattern...
متن کاملPredicting Greater Prairie-Chicken Lek Site Suitability to Inform Conservation Actions
The demands of a growing human population dictates that expansion of energy infrastructure, roads, and other development frequently takes place in native rangelands. Particularly, transmission lines and roads commonly divide rural landscapes and increase fragmentation. This has direct and indirect consequences on native wildlife that can be mitigated through thoughtful planning and proactive ap...
