Rare Plant Associations, Oregon Dunes National Recreation Area, Sutton Recreation Area, and Heceta Sand Dunes ACEC/ONA

摘要

In 2011, USFS requested the services of Portland State University's Oregon BiodiversityudInformation Center (ORBIC) to update its assessment of rare plant associations that occur onudcoastal sand dunes. The study area in this report includes dune habitats on the Siuslaw National Forest's Oregon Dunes National Recreation Area (NRA), the Sutton Recreation Area (RA) north of Florence, and BLM's Heceta Dunes Area of Critical Environmental Concern/ Outstanding Natural Area (ACEC/ONA) adjacent to the Sutton unit. The report focuses on plant associations occurring on sand dunes and does not include rare plant or animal habitat issues.udMethods
