The Appalachian Mountain Joint Venture worked with partners to develop new Forest Management Guidelines for improving the condition of Appalachian hardwood forests for Cerulean Warbler. This species’ population has plummeted by nearly 70% over the last half century, with the loss and degradation of large areas of mature deciduous forest contributing to those declines. The new guidelines provide land managers with recommendations for conserving and enhancing habitat. The guide is based largely on the Cooperative Cerulean Warbler Forest Management Project in the states of Ohio, West Virginia, Tennessee, and Kentucky, which provides partner organizations with resources to assist wildlife managers and biologists in timber management decision-making.
