The Sierra Nevada Ecosystem Project was requested by Congress in the Conference Report for Interior and Related Agencies 1993 Appropriation Act (H.R. 5503), which authorized funds for a "scientific review of the remaining old growth in the national forests of the Sierra Nevada in California, and for a study of the entire Sierra Nevada ecosystem by an independent panel of scientists, with expertise in diverse areas related to this issue."

This publication is a digital version of the set of reports titled Sierra Nevada Ecosystem Project, Final Report to Congress published in paper form by the Centers for Water and Wildland Resources of the University of California, Davis. The reports consist of Wildland Resources Center Report No. 39 (Summary), No. 36 (Vol. I - Assessment summaries and management strategies), No. 37 (Vol. II - Assessments and scientific basis for management options), No. 38 (Vol. III - Assessments, commissioned reports, and background information), and No. 40 (Addendum). Vol. IV is a computer-based catalogue of all public databases, maps, and other digitally stored information used in the project. Vol. IV materials are listed under the SNEP name and available on the Internet from the Alexandria Project at the University of California at Santa Barbara and the California Environmental Resource Evaluation System (CERES) project of the Resources Agency of the state of California (see links below).
