Estimated number of breeding pairs of LeConte's sparrow based on the amount of grass, trees, and/or hay in the landscape. Landscape scale varied from 1/4- to 2-mile radius depending on the species. Pair estimates were calculated for grass patches >=1 ha, extrapolated to 40-ac cells, then smoothed by averaging over a 1-mile radius. Models were based on point count surveys conducted in 2003-2005 throughout the Tallgrass Prairie Pothole Region. Point count locations were stratified by cover type, the amount of grass in the landscape, and USFWS Wetland Management District boundaries. Landcover data were derived from 2000 Thematic Mapper imagery. Grid values = number of breeding pairs per 30-m pixel.

Within grassland communities of the GPLCC one such key indicator species is the Lesser Prairie-chicken (Tympanuchus pallidinctus). Lesser Prairie-chicken range extends across the southern portion of the GPLCC area throughout Texas, Oklahoma, New Mexico, and Kansas. Lesser Prairie-chickens are a good target species because they are widely distributed across the southern GPLCC, are a species of conservation concern, have large home ranges, and are likely sensitive to anthropogenic disturbances. Similarly, the Greater Prairie-chicken (Tympanuchus cupido), is a species of conservation concern, with large home range, distributed across the northern portion of the GPLCC including portions of Oklahoma, Kansas, Nebraska,...

Reports document development of models and Decision Support Tools (DSTs) that inform conservation delivery for easements and habitat management within the Flint Hills Legacy Conservation Area (LCA) that address population and habitat objectives for surrogate species. Objectives include: 1) survey Henslow’s sparrow throughout the LCA; 2) gather habitat data along survey routes; 3) develop Flint Hills wide relative probability of occurrence, density, and habitat models for Henslow’s sparrows based on data gathered; and 4) apply models to create spatially explicit desicion support tools for use in the FWS Flint Hills LCA prioritization system, Region 6 surrogate species, and to support US FWS Partners for Fish & Wildlife...

Synopsis: Reviews information on grassland bird habitat requirements including a focus on the importance of grassland cover, size of contiguous patches, and other landscape factors. Some species require large blocks of unbroken grassland habitat for nesting. In general, where large blocks of undisturbed grassland occur, grassland birds are able to fulfill most of their requirements during the nesting season. For many bird species, these habitats provide winter and migration cover as well. The more grassland available in an area, particularly in large unbroken blocks, the greater the number of area-sensitive grassland birds the area is able to support. Pastures and crop fields also often provide attractive cover...

Grassland birds have declined more rapidly than any other group of land birds in North America in the last 50 years, with populations of Spragues Pipit, Chestnut-collared and Thick-billed Longspur, and Bairds Sparrow having declined 65-94% during this period. Developing strategic conservation plans for grassland birds requires an understanding of their individual population ecology, along with their community dynamics amongst species. Few studies have focused on understanding how adult density during the breeding season relates to nesting performance (e.g., nest density and nest success) and how abiotic and biotic factors influence these individual demographics. This proposed work complements concurrent studies...

Unconventional oil development in the Bakken shale region has increased rapidly as a result of new technologies. This region also supports a particularly high density and diversity of grassland bird species, which are declining across North America. We examined grassland bird response to unconventional oil extraction sites (i.e. developed with hydraulic fracturing and horizontal drilling) and associated roads in North Dakota. Our goal was to quantify the amount of habitat that was indirectly degraded by oil development, as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 149 m of roads (95% CI: 4 – 294 m), 267 m of single-bore well pads (95% CI: 157 – 377 m), and 150 m of multi-bore...

Grassland birds have declined more rapidly than any other group of land birds in North America in the last 50 years, with populations of Spragues Pipit, Chestnut-collared and Thick-billed Longspur, and Bairds Sparrow having declined 65-94% during this period. This proposed cross-programmatic collaborative project between Migratory Birds and Refuges will expand on a growing network of Motus automated radio telemetry receivers (stations) to provide the first fine-scale quantitative assessment of the migratory period for regional priority grassland songbirds, which will inform key knowledge gaps about migration routes and stopover locations. Data collected via Motus automated telemetry tracking will allow the FWS and...

Synopsis: This paper summarizes significant findings from literature related to the effect of noise on wildlife, emphasizing the effects of road traffic noise on birds. Many studies from the United States and the Netherlands indicate that road noise has a negative effect on bird populations, particularly during breeding season in a variety of species. In this paper, ‘effect distances’—distances at which bird density decreases—are reported at a range of two to three thousand meters from the road. Effect distances tend to increase with traffic density, being the greatest near large, multilane highways. In a study of woodland species, 26 of 43 (60%) were found to show a decrease in population densities with effect...

Conclusions: When isolated, larger patch size correlates with higher species density and occurence in area-sensitive grassland birds Thresholds/Learnings: Synopsis: This paper examines the influence of landscape fragmentation and isolation of Conservation Reserve Program (CRP) grasslands on grassland breeding bird populations in the northern Great Plains states. The study explores the relationship between species occurrence and density, and patch size by tracking 15 bird species on 303 restored grassland areas. Locating CRP grassland fields near existing grasslands, or establishing one large CRP field rather than several small fields, benefits area-sensitive grassland bird species. Caveats: Inconsistent findings...

While we assessed the vulnerability of a number of different wildlife and plant species to climate change, none of those species exhibited high vulnerability to changes projected for the region and there was limited differentiation in vulnerability between the individual species. Given this shared level of vulnerability to climate change, we chose to focus our adaptation planning on grassland birds as they represent a large group with a diversity of habitat needs. These birds are obligate grassland wildlife species which have great potential to act as indicators for habitat quality since different species have distinct habitat structure needs. Participants in the adaptation planning workshop agreed that if the GP...

With the ultimate goal of conserving and restoring threatened native grassland prairies and the wildlife that depend on them, the National Audubon Society (Audubon) is facilitating a landscape conservation design for the grassland birds in the greater Chicago region. As a first step in this process standardized avian point count surveys conducted primarily by citizen volunteers were combined with landcover composition and configuration, soils, and vegetation productivity data to model abundance of five grassland bird species. Models were updated with additional data and expert review in 2015 and now provide map outputs of existing grassland bird habitat and population estimates for species of conservation concern...
