Clients often commission ESL to undertake a reptile survey where they are known to be present in an area or when habitats are suitable for reptile species, this is usually determined by one of our expert ecologists.
The survey methodology includes a walked transect survey, deploying and checking artificial refugia. The walking survey involves the ecologist walking a pre-determined transect line along side all eco-tones where reptiles would most likely be found basking. Along this route, the ecologist will check the previously laid artificial refugia along with any natural refugia and this is repeated on several occasions over the season.
Reptile surveys should ideally be undertaken at very specific times to maximise detectability, which is generally between April and May. Late August to late September can also be useful for seeing juvenile animals but July and early August are generally less favourable months for surveying due to the days being hotter. Peak air temperature should be between 9-20°C. Bright sunshine is favourable on cooler days and hazy or intermittent sunshine is favourable when warmer.
Our ecologists advise on a wide spread array of reptile survey and mitigation. They undertake the necessary works to ensure a successful outcomes for client and wildlife alike. We design Mitigation on a site by site and species basis. Recent mitigation projects include grass snake, great crested newt and common lizard.
To avoid any delay to your schedule it’s important to plan for the survey season right at the beginning of your planning and development process, this means getting us involved early. Mitigation should only be undertaken when reptile species are active and not during the hibernation periods. This means there could be a delay if your don’t schedule in your reptile survey early enough.
