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...

Habitat fragmentation and degradation are considered to be a leading causes of long-term population declines of Northern Bobwhites and many other species of grassland birds, such as Eastern Meadowlark. Research is needed to understand the factors causing habitat loss and fragmentation and to identify the areas that are high-probability candidates for successful restoration so that optimal decisions can be made. For example, uncertainty exists regarding the impacts of energy development activities or climate change that affect significant portions of wildlife populations in the GCP LCC. Furthermore, changing land ownership coupled with woody shrub and exotic grass encroachment have reduced the amount and quality...

Capacity to prioritize barrier removals in the Great Lakes basin is currently limited by lack of data on the passability of road crossings and dams for both unwanted invasive species and desirable native migratory fishes. Building upon our initial barrier inventory, this project has two key elements. First, we are testing whether our landscape statistical models accurately predict the upstream limits of fish migrations along the Wisconsin coast of Lake Michigan. This involves intensive field work to determine the actual upstream limits of suckers, pike, and steelhead during the spring migration. Second, we are collecting systematic data on the size and condition of dams throughout the Lake Michigan basin. These...
