Modeling the distribution of migratory bird stopovers to inform landscape-scale siting of wind development. [PDF]

PLoS ONE, 2013
Conservation of migratory birds requires understanding the distribution of and potential threats to their migratory habitats. However, although migratory birds are protected under international treaties, few maps have been available to represent ...

The Influence of Grazing Systems on Bird Species Richness and Density in the Nebraska Sandhills

Diversity, 2023
Grazing is the de facto method of habitat management used in much of the Nebraska Sandhills. Ranchers use a variety of grazing systems, and our goal was to evaluate the effects of systems on grassland birds.

History of grassland birds in eastern North America [PDF]

, 1999
Until recently the severe decline in the populations of many species of grassland birds in eastern North America has aroused relatively little concern or conservation action.

Effect of highways on breeding birds: Example of Hulunbeier, China

Global Ecology and Conservation, 2021
Roads have diverse influences on surrounding biodiversity, especially birds. Here, we evaluated the ecological influences of a highway on avian diversity in the Erka Wetland Reserve (Inner Mongolia, China) to guide future road construction projects. Here,

The Conservation Reserve Program and Grassland Birds

Conservation Biology, 1993
Several bird species that breed in the temperate grasslands of North America, many of which winter in the Neotropics, declined in abundance during the past quarter century. The Lark Bunting (see Table 1 for scientific names) and Grasshopper Sparrow, as examples, declined by about half during that period, as indexed by the U.S. Fish and Wildlife Service'

The role of grazing management practices and tussock-forming plants on grassland birds in the Argentine Pampas

Discover Conservation
The structure of vegetation significantly impacts grassland birds. In temperate Southeastern South America (SESA), different cattle grazing practices shape grassland vegetation structure, influencing bird abundance and richness. We studied SESA grassland

Grassland birds and dairy farms in the northeastern United States

Wildlife Society Bulletin, 2014
Although grassland birds are declining throughout their North American range, and these declines are associated with agricultural land conversion or intensification, no broad‐scale market‐based conservation plan has been enacted.

Quantifying avian relative abundance and ecosystem service value to identify conservation opportunities in the Midwestern U.S.

Avian Conservation and Ecology, 2016
Grassland birds are highly imperiled because of historical habitat loss and ongoing conversion of grasslands to agricultural and urban land uses. Therefore, prioritizing and further justifying conservation action in remaining grasslands is critical to ...

Converting CRP grasslands to cropland, grazing land, or hayland: Effects on breeding bird abundances in the northern Great Plains of the United States

Global Ecology and Conservation, 2023
Recent declines of grassland bird populations in North America are linked to habitat loss and fragmentation associated with agricultural practices. One tool used to conserve soil, water and wildlife habitat on agricultural fields is the U.S.
