ABSTRACT / Military installations provide important native habitat for songbirds, including many species that have experienced population declines in recent decades. As part of the Land Condition Trend Analysis (LCTA) program to
Many songbirds that breed in North America have undergone population declines in recent years, particularly those that nest in shrublands and grasslands (Askins 1993; Vickery and others 1999; Vickery and Herkert 2001). Populations are influenced by many factors, yet habitat loss and degradation (e.g., fragKEY WORDS: Index of relative difference; Landbirds; LCTA; Military installations; Population monitoring; Species richness Published online January 12, 2005. *Author to whom correspondence should be addressed; email:
