Acknowledgments
This inventory was completed with the cooperation and assistance of many
organizations and individuals. The Washington Department of Natural Resources

identification. County assessors provided ownership information. Ecologists within
the National Forest System trained crews in plant identification and ecosystem
classification. Timber companies and many individuals allowed access to their
forest lands.
