Invertebrates, Amphibians and Reptiles
An important component of the aquatic ecosystem, invertebrates are consumers and providers, detritivores, predators and prey. Water quality can be estimated by their presence and species composition within the waterbody. They are a useful predictor of fish activity and the composition of the fish assemblage. Invertebrate assemblage composition can be used as an indicator of pollution, particularly chronic pollution events. Invertebrates are also an important food source for fish species. Within the aquatic system, many terrestrial invertebrates start out life under the water, before completing their life cycle above the surface. BFJ have considerable experience in invertebrate sampling and species identification. We work with the water industry, corporate and civil engineering sectors as well as NGO’s, rivers trusts, local interest groups, and fisheries to provide effective surveys that generate accurate data on the invertebrate composition of the waterbody.
We also carry out surveys for macro-invertebrates such as native white-clawed crayfish and invasive species, such as signal crayfish. We undertake trapping and torch searches,
as well as counts and density estimates.We provide full reporting services, data analysis, recommendations, habitat design, creation and implementation and mitigation measures to ensure the native crayfish is adequately protected while assisting with planning and development opportunities, simultaneously improving crayfish habitat.
We venture out of the aquatic environment to survey terrestrial invertebrates too. We undertake dragonfly and damselfly surveys and provide riverine fly life assessments.Within the river corridor we also undertake surveys for amphibians and reptiles.
