1. CCE List of Critical Ecosystem Services
Charge from Terry Chapin: Based on the discussion at the workshop, please send me a revised list of the 6 most critical ecosystem services at your site (critical in the sense that people most rely on or value, or that potentially underpin other important ecosystem services; that may be vulnerable because the trend in the service has been towards degradation; lack of technological substitutes; and/or may be unique to a particular site, or only delivered locally (no off-site substitutes).
For each of these services please provide a brief description (phrase) explaining why you think it is critical at your site. Please do not include any supporting services in your list of critical services; we will assume that all supporting services are subsumed and essential for the services directly used by people (provisioning, regulating, cultural).
Food The Southern California nearshore and coastal Zone supports various fisheries, both commercial and recreational, ranging from sea urchins collected by divers, live fish from the rocky benthic to trawling for pelagic fish.

2. CCE List of Interacting Ecosystem Services
Charge from Terry Chapin: Please send me one or more (up to 3) clusters, each consisting of three interacting critical services at your site that will help us identify key synergies, tradeoffs, and interactions. Please explain briefly how the three services within each cluster interact at your site.
Water purification recreation pest regulation
& generation: Tradeoffs are made between the amount of
treated and untreated sewage allowed into the ocean and impacts of this on
recreation via beach closures and degradation of the environment. It is possible that the increasing trend of
harmful algal blooms along the
Natural Hazard abatement & generation cultural identity recreation: To prevent erosion of the coastline homeowners increasingly demand that seawalls are build to protect buildings close to the beach. Seawalls, however, lead to a degradation of the beaches which negatively impacts use of the beaches by locals and tourists.
