Demography and site fidelity of a grassland bird, the Henslow's Sparrow, in powerline right-of-way habitat

Journal of Field Ornithology, 2022
Grassland birds are among the fastest declining avian species in North America, primarily due to habitat loss. In the southeastern United States, much grassland and open savanna habitat has been converted to timber production or agriculture, neither of ...

Additionality in Grassland Easements to Provide Migratory Bird Habitat in the Northern Plains

Journal of Agricultural and Resource Economics, 2017
Native grassland in the Prairie Pothole Region (PPR) is important habitat for migratory birds, particularly ducks. Much of this grassland is at risk for conversion to cropland. Permanent easements, managed by the U.S.

Influence of agricultural management, sward structure and food resources on grassland field use by birds in lowland England. [PDF]

, 2005
Agricultural management of grassland in lowland Britain has changed fundamentally in the last 50 years, resulting in spatial and structural uniformity within the pastoral landscape.

Planted Grasslands and Native Sod Prairie: Equivalent Habitat for Grassland Birds?

Western North American Naturalist, 2009
Little is known about how avian relationships to tracts of native sod prairie compare with avian relation- ships to single and multiple species of cool- and warm-season grassland plantings. We compared grassland bird species richness and density in 5 grassland cover types (n = 97) in the tallgrass prairie region of eastern South Dakota and west- ern ...

Home ranges and hatching success of threatened Eurasian curlew in north-eastern Europe relates to habitat type: Natural vs. agricultural landscapes

Global Ecology and Conservation
Farmland birds are among the most threatened species in Europe, largely as a result of the intensification of agriculture leading to widespread biodiversity losses.

Bird community patterns in sub–Mediterranean pastures: the effects of shrub cover and grazing intensity

Animal Biodiversity and Conservation, 2011
Shrubs are widely considered a threat to grassland biodiversity. We investigated the effects of shrub cover and grazing intensity on bird communities in sub–Mediterranean pastures in Bulgaria.

Do roads lead to grassland degradation or restoration? A case study in Inner Mongolia, China [PDF]

, 2011
We use satellite remote sensing data of grassland cover in Inner Mongolia, China to test whether the existence of and the size of roads in 1995 is associated with the nature of the grassland in 2000 and/or if it affects the rate of change of the ...
