Ecology Surveys for Water Support Main

Three Valleys Water

Keystone were commissioned to undertake Badger, Great Crested Newt and reptile surveys of the proposed alignment of a 3.4km support main. Ecologists carried out Great Crested Newt Habitat Suitability Index assessments of seventeen waterbodies within 250m of the proposed alignment followed by presence/absence surveys of seven waterbodies with the potential to support Great Crested Newts. Ecologists searched all habitat within 100m of the proposed alignment for signs of Badger activity and following an assessment of suitable reptile habitat, refugia were set out prior to the commencement of seven-day presence/absence surveys, which were extended to fifteen days where reptiles were found to gain an indication of population size.
