Abstract
This study was initiated to develop cause and effect relationships between Army training activities and bird populations throughout the continental United States. Installations in Kentucky, Louisiana, Texas, and Washington were selected as representative of diverse ecosystems and of extent of training. Birds were separated into 31 guilds to assist in the analysis between different ecosystems. The results showed that (1) guild theory can be useful in impact analyses within and between ecosystems, (2) tracked vehicles disturb bird populations because of habitat alteration and reduction, (3) the change in biomass ranged from 20.9to–55.3 percent and is dependent on the extent of training and ecosystem type, and (4) species replacement should be a major concern, with nine endemic species being replaced by three endemic and two introduced species. Because of similarities between tracked vehicle training and some construction activities, much of this information may be useful for analysis of civilian activities as well as military.
