We offer aquatic ecology monitoring services for a range of freshwater environments across the United Kingdom. Our ecologists are highly experienced in collection and analysis of ecological data, and we can advise on the most appropriate survey methods to fit your requirements. We currently offer:
Macroinvertebrate Sampling and Analysis
Freshwater macroinvertebrates are useful indicators of waterbody health and biological water quality. They have a range of sensitivities and tolerances to different environmental disturbances. Classifications based on macroinvertebrate community structure and relative abundances are a key part of Water Framework Directive (WFD) targets. We provide macroinvertebrate sampling and analysis services in standing and running water habitats. Our services include standard methodologies such as kick and sweep sampling alongside more bespoke options such as Surber and dredge sampling. We offer taxonomic analysis of samples to either family or species level.
Our macrophyte surveyors are Environment Agency accredited
We provide specialist macrophyte surveys for a range of clients for a variety of purposes. These include Water Framework Directive (WFD) monitoring, condition assessment of designated sites (SSSI/SPA/SAC/RAMSAR) using the Common Standards Monitoring (CSM) methodology, Mean Trophic Rank (MTR) and bespoke surveys.
Macrophytes are often used as a clear indicator of the impact of increased nutrients in rivers and standing waterbodies. They are also affected by a range of pressures which include water abstraction, flow impoundment, channel modification and acidification. The assemblage and coverage of macrophytes present in a river indicate how well that river is functioning and this can be compared against predicted combinations, quantity and coverage of macrophytes expected to be present depending on the waterbody type and its water quality.
Macrophyte communities can form important components of statutory designated sites and surveys will inform condition assessments. Surveys can also identify rare and protected plant species that may be of particular conservation concern.
River Corridor Survey and River Habitat Survey
River Corridor Survey (RCS) and River Habitat Survey (RHS) are methods of mapping the ecological and physical characteristics of a stretch of river, its banks and the land close by. RCS/RHS are designed to map and evaluate the river corridor. They can be used for a variety of reasons including: determining the impacts of works in or near rivers, assessing the conservation value of a river and identifying opportunities to rehabilitate and enhance degraded habitats.
Data quality is of the utmost importance to us, and consequently we ensure all surveyors meet the relevant technical standard for any fieldwork being carried out. When conducting fieldwork our experienced RCS surveyors follow the guidelines given in the National Rivers Authority’s Conservation Technical Handbook 1 (1992).
