Book Description
The southeastern myotis (Myotis austroriparius) is a medium-sized bat with grayish-brown, woolly fur. This species primarily is found in the southeastern United States. Its range extends from southeastern North Carolina south to peninsular Florida, west to eastern Texas and Oklahoma, and north to western Kentucky, southern Illinois, and southern Indiana. The southeastern myotis is considered a species of special concern because of significant population declines. It migrates between cooler winter caves used as hibernacula and warmer summer caves used for rearing young. In noncave regions, the southeastern myotis roosts in large hollow trees or man-made structures. The southeastern myotis has been documented on at least two military installations in the southeastern United States. This report is one of a series of Species Profiles being developed for threatened, endangered, and sensitive species inhabiting southeastern United States plant communities found on military installations.

Book Description
The gray bat (Myotis grisescens) is a medium-sized bat with gray or chestnut-brown fur. The species was listed as Federally endangered in 1976 throughout its range by the U.S. Fish and Wildlife Service, primarily due to human disturbance, environ- mental disturbance, and impoundment of waterways. Gray bats are year-round cave residents but migrate between caves in wintering and summering areas of the midwestern and southeastern United States. Populations are mainly concentrated in Alabama, Arkansas, Missouri, Tennessee, and Kentucky. The species was been documented on one military installation in the southeastern United States; installations with suitable habitat in other sections of the United States should also benefit from this profile. This report is one of a series of Species Profiles being developed for threatened, endangered, and sensitive species inhabiting southeastern United States plant communities. The work is being conducted as part of the Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP). The report is designed to supplement information provided in plant community management reports for major United States plant communities found on military installations. Information provided on the gray bat includes status, life history and ecology, habitat requirements, impacts and causes of decline, habitat assessment techniques, inventory and monitoring, and management and protection.

Book Description
The gray bat (Myotis grisescens) is a federally listed endangered species known to occur on several U.S. Army installations in the eastern United States. Seven Army installations and one Air Force base have documented gray bat populations, and these facilities have undertaken programs to protect roosting and foraging sites important to the species. This report reviews the status of the gray bat throughout its range and assesses the population status of gray bats at major hibernacula in Arkansas, Missouri, Kentucky, and Tennessee. Survey records obtained from state agencies showed that in recent years gray bat populations have increased significantly in most primary summer and winter caves. In 2005 the Army cooperated with the U.S. Fish and Wildlife Service and other state and Federal agencies to undertake a range-wide survey of primary gray bat hibernacula. Hibernacula surveys were conducted from December 2005 - January 2007 in ii caves considered to be critical wintering sites. Results of the survey showed stable to increasing population levels across the species' range. Additionally, a Department of Defense Legacy project was implemented to support conservation efforts to assist with recovery of the gray bat. The project funded improvements and protection of several cave sites in Tennessee and Kentucky, hibernacula surveys of selected caves, and summer surveys of maternity caves in Tennessee. The Army Threatened and Endangered Species Research Program also provided support for these tasks. The current range-wide population of the gray bat is estimated at approximately 3.4 million bats.

Book Description
This document is one in a series of technical notes produced by the U.S. Army Engineer Research and Development Center (ERDC) under the Ecosystem Management and Restoration Research Program (EMRRP). The technical notes identify sensitive species potentially impacted by U.S. Army Corps of Engineers (Corps) reservoir operations and are products of the EMRRP work unit entitled "Reservoir Operations - Impacts on Habitats of Target Species" (Dickerson, Martin, and Allen 1999; Kasul, Martin, and Allen 2000). This document is one of a group of technical notes that provide information on selected bat species that have the potential to occur on Corps projects in the eastern United States and be impacted by Corps activities. It is linked to a technical note (ERDC TN-EMRRP-SI-24), which presents an overview of general habitat requirements, impacts, and management needs for these species. For management purposes, the endangered gray bat (Myotis grisescens) (Figure 1) is considered a riparian species because it may forage over water or in riparian zones surrounding streams and lakes on Corps lands during summer months. This technical note describes the distribution, legal status, ecology, potential impacts, and management guidelines for the gray bat.
