Habitat fragmentation is considered to be a leading cause that is responsible for the long-term population declines of Northern Bobwhites. There are numerous factors responsible for habitat fragmentation such as expanding suburbanization, intensification of agricultural and forestry practices, and invasions of exotic plants; the unifying theme is how people use land for settlement and the production of food and fiber. As patches of habitat become smaller and more isolated, populations experience a lower probability of persistence that results in local extinctions, which can lead to larger, and perhaps even regional extinctions. However, we lack a strong empirical and quantified basis that describes the numerical...

The northern bobwhite (Colinus virginianus) has experienced range wide declines over the last several decades, primarily because of reduction to habitat through loss and fragmentation. For studies on population decline and habitat, spatial scale is very important: the effects of habitat structure at local spatial scales may depend on the larger landscape scale, and patterns may be more evident at different scales. As northern bobwhite populations continue to decline, there is a need for studies that address habitat changes and their impact on northern bobwhite population trends and persistence at three spatial scales (regional, county, and home range). Our goal was to assess changes in habitat and land use and their...
