A survey of current breeding habitats: Chapter 5 in Status, ecology and conservation of the Southwestern Willow Flycatcher (RMRS-GTR-60)

The distribution and abundance of a species across a landscape depends, in part, on the distribution and abundance of appropriate habitat. If basic resource needs such as food, water, and cover are not present, then that species is excluded from the area. Scarcity of appropriate habitat is generally the key reason for the status of most rare and endangered species. An understanding of an endangered species’ habitat characteristics is crucial to effective management, conservation and recovery.
