The Fire Effects Information System (FEIS) is a computer-based, menu-driven encyclopedia of fire effects and general ecological information for plant species, wildlife species, and plant communities. It provides interpreted, summarized information in an easy-to-use format and will soon be available at any location with computer-to-computer communication capabilities. When fully operational, FEIS will be national in scope. At present its main emphasis is on aridland shrubs and associated vegetation. New information is being added on continuing basis. A list of FEIS contents to date and a sample output are included.
