Quick Answer
For sustainable upland bird populations, a minimum of 10-20 acres of habitat per 100 acres of agricultural land is recommended, with a mix of native grasses, shrubs, and forbs to provide diverse nesting cover and food sources.
Habitat Requirements for Upland Birds
Research has shown that native grass restoration is critical for maintaining healthy upland bird populations. To achieve this, it’s essential to restore a mix of native warm-season grasses, such as big bluestem and switchgrass, which provide excellent nesting cover and food sources for birds like the bobwhite quail and prairie chicken.
CRP and Native Grass Restoration
The Conservation Reserve Program (CRP) has been instrumental in promoting native grass restoration, particularly in the Great Plains region. By enrolling marginal agricultural land into CRP, landowners can establish native grasses, which in turn provide vital habitat for upland birds. For example, a 100-acre field can be planted with a mix of native grasses, including 40% big bluestem, 30% switchgrass, and 30% little bluestem, to create a diverse and resilient ecosystem.
Minimum Habitat Requirements
A study by the Pheasants Forever organization found that a minimum of 10-20 acres of habitat per 100 acres of agricultural land is required to support sustainable upland bird populations. This habitat should include a mix of native grasses, shrubs, and forbs, as well as a source of water, such as a pond or stream. By achieving this level of habitat diversity and density, landowners can create a thriving ecosystem that supports a wide range of upland bird species.
