Ice Plant (Carpobrotus edulis) is an extremely invasive species from South Africa.

The Seashore has more than 10 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 30 are invasive enough to threaten the diversity of native plant communities in the Seashore. The Seashore also supports 51 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.
