Epibiota remote monitoring from digital imagery: Interpretation guidelines.

Abstract

There is increasing recognition that the effective acquisition and interpretation of underwater video and still image data for biodiversity is growing in importance. Numerous organisations (e.g. Statutory Nature Conservation Bodies (SNCBs), Inshore Fisheries Conservation Authorities (IFCAs), environmental consultancy agencies, industry and academic institutes) are now engaged in this work for a variety of different purposes, including:  Marine habitat mapping of physical seabed habitats and features in support of a variety of national and international initiatives, e.g. Integrated Mapping For the Sustainable Development of Ireland's Marine Resource (INFOMAR).  Characterisation of the epibiotic attributes of seabed habitats and features e.g. in support of the Marine Strategy Framework Directive, Water Framework Directive, designation of Marine Protected Areas (MPAs, European and National), marine development applications and licensing.  Monitoring trends in seabed habitat features and their associated epibiotic communities, e.g. in support of monitoring the effectiveness of management measures implemented to achieve given conservation objectives within MPAs and also to assess and monitor predicted impacts for given marine developments and the effectiveness of mitigation measures implemented. The guidelines in this document provide a summary of current best practice for the interpretation of video and stills imaging data of benthic substrata and epibenthic species to ensure that data are interpreted to fulfil the objectives of a survey. These guidelines form part of the epibiota component of the NMBAQC scheme, reporting to the Healthy and Biologically Diverse Seas Evidence Group (HBDSEG) under the UK’s Marine Monitoring and Assessment Strategy (UKMMAS).
