The development site in Lydden had a reptile report by the same author of the one for Westmount recording a high population of slow worms, which as it is an undeveloped site adjacent to farmland and less than half a mile from an internationally important nature reserve is not surprising.
There is now an anti-slow worm fence around the whole site, and all resident slow worms are supposed to have been rehomed in suitable housing outside the site. That is standard procedure for these type of situations. (Stop
, this is serious
