The park maintains an herbarium in the museum collection for the purpose of research, education and interpretation, and to serve as a record of the plants of the Point Reyes Peninsula. Additional specimens are desirable to complete the herbarium collection, especially from the GGNRA North District lands The collection is expected to grow as a result of park activities and scholarly research.
Each species of seed plant growing in the park, native and non-native, should be represented by an herbarium specimen, including fruit and flower and root whenever possible, with additional specimens illustrating regional differences within Point Reyes and important variations in form, color, or hybrids. Each species of moss, liverwort, hornwort, algae, fern and fern ally should also be represented by a characteristic specimen.
At least one new to science species of lichen has been recently found on the Peninsula and the collection is expected to grow.
