Coity Wallia Commons Biodiversity Enhancement Project

Raising awareness of issues through education and community engagement.
Improving priority habitats with particular emphasis on shrill carder bee, high brown fritillary and marsh fritillary.
Contributing to the local economy.


Coity Wallia Commons Biodiversity Enhancement Project was the Biffa Award Flagship Project for 2010.

The primary aim of the project was to restore and reconnect 1,063 hectares of priority habitats on Cefn Hirgoed and Mynydd y Gaer commons north of Bridgend.

With particular emphasis on management for the Marsh fritillary, High Brown Fritillary, the Bog Bush Cricket and the Shrill Carder Bee.

Coity Wallia Commons are close to the conurbation of Bridgend and are subject to anti-social behaviour.
