Otter Survey Tracks

The experienced ecologists at Acer Ecology are able to perform otter surveys across Carmarthenshire, including Carmarthen, Ammanford, Burry Port, Kidwelly, Llansteffan and Newcastle Emlyn. We also have the capacity to take on surveys in Pembrokeshire, Ceredigion and Swansea.

Otters and their habitats are fully protected under UK and European law.

Developments affecting otters, or their resting places, require a European Protected Species Licence prior to the commencement of bank-side works. It is therefore important to detect the presence of otters at an early stage in the planning process, as this could save you both time and money in the long run.

Otter surveys are not seasonally constrained and can be undertaken throughout the year, although they can be limited by vegetation cover and weather conditions.

Otters and Mitigation Strategies

Mitigation for otters can include locating site compounds away from riverine habitat, restricting lighting in the area near the watercourse at night and excluding construction workers from these areas. If a proposed development is likely to result in the significant loss of habitat, mitigation may involve the creation of habitat and the construction of artificial otter holts in sections of the watercourse which will remain unaffected by the works. Sympathetic bridge design and the installation of otter-proof fencing along existing or new roads may also be required to ensure that otters are not forced onto any nearby carriageways during times of high water.

Our ecologists have designed successful mitigation strategies for developments found to be in close proximity to otter habitat, allowing the developments to go ahead with minimal disruption.
