Mae mesurau wedi cael eu rhoi ar waith i leihau effaith amgylcheddol y cynllun, i wella bioamrywiaeth yn yr ardal, gan gynnwys lleoedd diogel i fywyd gwyllt. Plannwyd 170,000 o blanhigion, gan ddarparu tua 14 hectar o rywogaethau brodorol newydd, coetiroedd a phrysgwydd, yn ogystal â thros 20 cilometr o wrychoedd newydd.
Measures have been put in place to minimise the environmental impact of the scheme to improve and enhance biodiversity in the area, including safe passages for wildlife. 170,000 plants, providing around 14 hectares of new native species, woodlands and scrub, as well as over 20 kilometres of new hedgerows were also planted.
