The Seashore has more than ten nonnative species of animals such as mammals, reptiles, and marine organisms. Of the over 900 species of plants in Point Reyes National Seashore, approximately 300 are nonnative. Of those, at least thirty are invasive enough to threaten the diversity of native plant communities in the Seashore. The Seashore also supports fifty-one special status (rare) plant species, many of which are directly affected by invasive nonnative species. Exotic species can have severe impacts on natural plants and animals and ecosystems.
Parks like Point Reyes are specifically mandated to control exotic species "up to and including eradication" of a population if that species does not meet an identified park purpose and if such control is "prudent and feasible." Only through the removal of exotics and other changes resulting from human disturbance can the NPS return its park units to the most natural condition possible and meet its mandate to preserve them in this condition for future generations.

Pacific Coast Science and Learning Center Research Project Summaries
From 2006 to 2009, Pacific Coast Science and Learning Center (PCSLC) communication interns assisted scientists conducting research through the PCSLC and the San Francisco Bay Area Inventory & Monitoring Network to produce a series of Resource Project Summaries, five of which were, in part, about non-native species at Point Reyes. These two-page summaries provide information about the questions that the researchers hoped to answer, details about the project and methods, and the results of the research projects in a way that is easy to understand.
