Determination of characteristics of trees and habitats used by different bat species is necessary to complete a basic understanding of the ecology and interactions of tree-roosting bats and to develop management plans for forested areas. During the summers of 1999 and 2000, 5 male Indiana bats (Myotis sodalis) and 2 male and 5 female northern bats (M. septentrionalis) were mist-netted and subsequently radio-tracked to 14 and 21 roost trees, respectively, on the Wayne National Forest (NF) in Ohio.

This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.

The Northern Cumberland Plateau contains both extensive stretches of hardwood forests and remarkable biodiversity. The presences of unique and threatened wildlife species, including the Indiana bat (Myotis sodalis), have made the Plateau an area of concern. Future changes in forest conditions, ranging from declining timber markets to drastic increases in timber harvests, could prove to have significant impacts on M. sodalis. A study of M. sodalis occupancy on the Plateau indicated that although the species was difficult to detect and may not be very common on the Plateau, it could potentially be very sensitive to human disturbance. Although only a reduction in the probability of detection resulted from increased human activity, prolonged disturbance could also reduce occurrence of the species. In order to better understand a larger area of concern for the species, a map was created to designate areas with high potential for M. sodalis maternity roosts. Based on expert opinions, the Analytical Hierarchy Process (AHP) was utilized to compare and rank habitat characteristics. Upland and riparian hardwood stands were determined to be the most important for the species' maternity roosts, while developed and agricultural areas were determined to be the least important. Several areas across Tennessee's Northern Cumberland Plateau were defined as having high potential for M. sodalis maternity roosts. Both the presence and potential for the species in the Plateau, combined with the changing forest dynamics in the Plateau, have made the area a special concern for forest, ecosystem and M. sodalis management.
