The U. S. Geological Survey (USGS) is offering a funding opportunity to a CESU partner to support a study of grassland bird communities under a changing climate.

Over the last half-century, populations of grassland birds declined by more than any other bird group in North America.

is because native grasslands have largely been converted to agricultural row crops, and the remaining prairies have become degraded through altered fire regimes, woody encroachment, the spread of invasive plants, and human development.

Land managers and conservation organizations are racing to preserve and restore these ecosystems to stem further loss of grassland birds.

Given limited resources, bird habitat models are needed to help managers prioritize where conservation efforts will be most effective.

In addition to habitat loss and degradation of native grasslands, increasing greenhouse gas emissions will likely change temperatures and rainfall patterns across the Great Plains.

This changing climate is expected to alter vegetation communities and the bird species that depend on them.

To date, predictions of bird response to a changing climate have focused on changes in temperature and precipitation, but vegetation productivity also depends on factors such as vegetation type and soils.

By studying how vegetation influences grassland birds across the western Great Plains, are creating maps of projected bird distribution, given vegetation and land-use change under multiple future climate scenarios.

Predictive bird distribution maps will help land managers and other decision-makers understand how the site-level projects fit within regional and climatic contexts.

A web-based application and raining modules accompanying these maps will increase capacity among Federal, State, Tribal, and private partners in their conservation planning under a changing climate.
