An investigation of benthic recovery and climate change resilience in the Englishman River estuary

SNAPSHOT: A benthic monitoring program will be added in 2018 to the ongoing Englishman River Estuary recovery study, situated on the east coast of Vancouver Island. This will complement investigations which have been ongoing, prior to and following the removal of a berm during 2017. Changes in salinity patterns, flow regimes, channel morphology, elevation, sediment size, and vegetation distribution are being assessed and these variables will be used to map distinctive areas of the estuary. Benthic samples will be collected from representative areas and monitored over the long term. Relative and total abundance, species diversity, biomass, and various derivatives of these data, such as mean body weight, dominant faunal groups by weight and abundance, and species diversity/richness indices will be used to assess changes in the benthos following berm removal, and to determine community resiliency to climate change. The study will be used to develop protocol for a BC coastal wide estuary monitoring program investigating ecosystem resilience to climate change. It is being led by members of the West Coast Conservation Land Management Program and is supported by The Nature Trust of BC, The Habitat Conservation Trust Foundation, Ducks Unlimited, Ministry of Forests, Lands, Natural Resource Operations and Rural Development, Environment and Climate Change Canada, Fisheries and Oceans Canada, BC Conservation Foundation and stewardship groups
