Services Relevance
to Site
Baseline Level Estimated Impacts of Classification Value Weighting Scale of Benefits Confidence
Lower Intermediate  Upper
Fish for human consumption Low, contributes to the food web  Stocks not at MSY Nil Nil  Minimal - Low, small increase in fish stocks possible  Low Minimal Moderate
Fish for non-human consumption Stocks reduced from potential maximum
Gas and climate regulation Minimal, in coastal areas Minimal  Nil Low Nil  High
