We thank Jim Bolte and Kenneth Greenlee for their hospitality during WHC’s site visit. The WILDLIFE HABITAT COUNCIL (WHC) is an independent, nonprofit assemblage of corporations, conservation organizations, and individuals dedicated to protecting and enhancing wildlife habitat. Created in 1988 and based in the greater Washington DC area, WHC strives to promote responsible environmental stewardship within the corporate management culture through the provision of expertise and resources to companies concerned with the protection of wildlife habitat on private landholdings. Over 2 million acres of private land is currently managed for wildlife through WHC- assisted projects in North America and around the world. WHC also works to broaden understanding of wildlife values through the incorporation of environmental education, volunteer participation, and community outreach programs.

We also recommend that discretion be used when distributing this document to others. This report is intended solely as a guidance tool for implementing wildlife habitat enhancement programs on corporate sites. WHC therefore cannot assume responsibility for local, state, and federal regulatory programs and authorizations. WHC strongly recommends that site managers consult with state and federal experts with regard to regulatory requirements in the region prior to implementing any activity in a regulated habitat. WHC can assist with the identification of appropriate regulatory contacts, if necessary.
