Protected Species Surveys

As well as standard surveys we can provide detailed ecological assessments, population estimates and behavioural studies of protected species. Our reports provide detailed impact avoidance guidelines and mitigation proposals to meet the requirements of NatureScot licensing and the planning process.
We can supervise the implementation of mitigation measures including design, build and restoration of habitats and species translocations.

Some of our protected animal species in Scotland are:

• Badgers
• Bats
• Barn owls
• Otters
• Red squirrels
• Great crested newts
• Water voles
• White-clawed crayfish
• Species of reptiles
• Species of birds
• Dormice

You can find a full list of Scotland’s protected species on the NatureScot website at: https://www.nature.scot/professional-advice/protected-areas-and-species/protected-species/protected-species-z-guide/

In addition to bat and badger surveys, we are often asked to conduct otter surveys.

Otter surveys

The Eurasian otter is the only native UK otter species, and is fully protected under the Conservation (Natural Habitats, &c.) Regulations 1994.
An otter survey may be required as part of the planning process, particularly if the development will affect a water body (river, stream, lake etc). Otters are highly territorial animals with large home ranges. Depending on the quality of the habitat and availability of food, males can range along rivers for 35km.

We carry out an otter survey by walking over the site and surrounding area, particularly close to water bodies, to look for evidence of otters such as dung (spraints), tracks and feeding remains. We will also look for otter slides (into water), holts (underground dens) or couches (above ground sites where otters rest during the day). The survey can be carried out at any time of the year, but it is often easier to find evidence during spring. However, as otter activity varies according to the season, it may be necessary to conduct several surveys throughout the year to establish to extent of the potential impact on the otters.

Once we’ve completed the survey, we will make an assessment of the likely impact of the proposed development on any otter population found. We’ll make recommendations in our report for mitigating the impact of the development and protecting the otter population. This may include such measures as:

• leaving a buffer zone along a river
• building viaducts or underpasses to allow otters to cross new roads
• installing mammal ledges on bridges and culverts to allow the otter to move alongside water bodies.

Otter licences

You may need a licence to examine otter structures, use cameras near holts, or conduct research that might disturb otters. Developers can apply for a licence to allow proposed development works that might affect otters. We can apply to NatureScot for a licence on your behalf.
Most land management practices are unlikely to affect otters or their holts, couches or other places of shelter. But land managers must consider any structures used by otters, as these are protected even when not in use.

If you have any questions regarding otters or other protected species on your land, give us a call and we will be happy to advise you.
