An assessment of the business and regulatory impacts of classifying the Sound of Gigha SPA.


Appendix A - Ecosystem Services Benefits, Sound of Gigha

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, contributes to the food web. Stocks not at MSY Nil Low, recovery of fish stocks possible in medium to long term from protection of benthic features Moderate, recovery of fish stocks possible in medium to long term due to extent of protection of benthic features Low Minimal - Low Moderate
Fish for non-human consumption Stocks reduced from potential maximum
Gas and climate regulation Minimal Minimal Nil Low Nil High
Non-use value of natural environment Moderate, bird species, and contribution of the site to SPA 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, possibly allowing some recovery Low - Moderate, range of features contributes to maintaining marine biodiversity Low 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 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, Low – moderate for upper scenario. Low Moderate
