Intertidal and Lagoon Macrofauna and Flora of Poole Harbour
Editors: Humphreys, J.
Poole Harbour, on the south coast of England, is one of Europe’s largest estuaries and is an important economic hub and centre for waterborne recreation. Here we describe intertidal and lagoon habitats, document an inventory (2002–21) of macrofauna and flora and make comparisons with earlier reviews. Since 2002, over 300 species have been recorded within intertidal mudflats, sandflats, lagoon habitats and upon hard substrata, approximately 9% of which are not native to the British Isles. These local stocks and assets comprised of living things represent part of the harbour’s ‘Natural Capital’ and provide ecosystem services. Time-series data since the 1970s are presented that indicate the range of popula - tion variability of important species, with some trends apparent. These can help managers determine the likelihood of ‘tipping points’ within the ecosystem. Robust and consistent benthic monitoring protocols combined with high resolution imagery of the harbour will improve the quality of data and aid the interpretation of future surveys.
