Coll and Tiree Special Protection Area: business and regulatory impact assessment

An assessment of the business and regulatory impacts of classifying the Coll and Tiree Special Protection Area.


Appendix A - Ecosystem Services Benefits, Coll and Tiree

Summary of Ecosystem Services Benefits arising from Classification of the Site as an SPA
Services Relevance
to Site
Baseline Level Estimated Impacts of Classification Value Weighting Scale of Benefits Confidence
Lower Intermediate Upper
Fish for human consumption Moderate, benthic habitat contributes to the food web web Stocks not at MSY Minimal Low, recovery of fish stocks possible in medium to long term from protection of benthic features (e.g. shellfish beds). Low Low Moderate, ecosystem response is uncertain
Fish for non-human consumption Stocks reduced from potential maximum
Gas and climate regulation Minimal, in coastal areas Minimal Nil Low Nil High
Non-use value of natural environment Moderate, bird species, and contribution of the site to MPA network, have non-use value. Non-use value of the site may decline Minimal Low, maintain features of site Moderate, protection of features of site from decline, and/or allowing some recovery Moderate, contributes to maintaining marine biodiversity in areas where significant non-use values identified by Kenter et al. (2013), e.g. Skye to Mull MPA. Low - Moderate Moderate, extent of features, responses to management measures, and value to society all uncertain
Recreation Moderate, features have recreational value, but there are substitutes. Value of site may decline Minimal, protection of features of site Low - Moderate, protection of features of site that contribute to recreation, possibly allowing some recovery Low, for individual features. Moderate for opportunity to understand response of range of features to management. Low Low – Moderate, extent to which research uses site in future uncertain.
Research and Education Moderate, features have research value, but there are substitutes Value of site may decline Minimal, protection of features of site Low, protection of key characteristics of site from decline, improving future research opportunities. Classification may play role in communicating management needs. Low Low Moderate, extent to which research uses site in future uncertain.
Total value of changes in ecosystem services Minimal - low for lower and intermediate scenarios, Minimal - moderate for upper scenario. Low Moderate
