Channel Islands
General Description
Situated west of Los Angeles,
the Channel Islands Biosphere Reserve represents one of the last examples of
natural Mediterranean ecosystems in North America and some of the few remaining
natural southern California coastal ecosystems. Characteristic features are
coastal sage scrub communities on the islands and exceptionally pristine
tidepools on the marine terraces surrounding them.
All of the islands have been altered to a greater or lesser extent by human
activities, including fires, farming and livestock grazing, fishing and numerous
house and road constructions. Many dominant plant species have been introduced
as well as animals such as black rat (Rattus rattus) and European rabbit (Oryctolagus
cuniculus). Manipulative research on exotic plants and animals is underway to
determine their impacts and to develop effective management actions to eliminate
their impacts. Unregulated tourism on the islands is another management problem.
The Channel Islands National Park, which is situated within the biosphere
reserve, maintains a visitor center and there are numerous educational programs
available. The local communities participate in management decisions through
public workshops and hearings and a local Fish and Game Commission.
