Channel Islands Snapshot Report

The seventh report in the South Coast Snapshot Series, Monitoring California’s Channel Islands, highlights several monitoring projects being conducted by various agencies and organizations in marine ecosystems around the Channel Islands. Monitoring these islands complements the ten state-funded marine protected area (MPA) baseline monitoring projects in the region to provide a more thorough understanding of South Coast marine environments.

Studies have found increased biomass of targeted and non-targeted species inside and outside of northern Channel Island MPAs since implementation in 2003, though response varied across the islands. Long-term monitoring will allow us to continue to track these changes over time and gain an understanding of the underlying causes.

This snapshot report, and the entire South Coast Snapshot Series, provides a foundation for rigorous science-informed decisions in the region. It is key ingredient in the State of the California South Coast Region report, which provides a comprehensive ecological and socioeconomic baseline characterization of the region.
