Coastal grazing marsh is a recognised Habitat of Principal Importance; listed in Section 41 of the Natural Environment and Rural Communities (NERC) Act, 2006.
Brackish water ditch habitats have distinct floral and faunal assemblages. Though these tend to be less species-rich than their freshwater counterparts, they support a range of species with a high fidelity to this habitat.
The limited extent of coastal brackish habitat means species faithful to these habitats are often nationally scarce.
Reasons for surveying these habitats include the assessment of the conservation value or sensitivity of a site, to monitor the impact of discharges, to map areas of contamination, and to monitor the presence of protected or introduced species.
Estuarine habitats can be surveyed in collaboration with Aquatonics Ltd.
Survey methodology is tailored to meet the needs of the project.
