The Wrexham County Borough includes areas of lowland and upland and the range of habitats and species associated with them.

The lowland areas have over 2000 ponds covering in total one square kilometre. These ponds are an important habitat for the protect species such as the great crested newt and the silver diving beetle, an extremely rare invertebrate only recently found in Wales. The County Borough has one of the largest breeding populations of great crested newts. The area includes Wales’s largest lowland bog, which is currently being restored after years of peat extraction for horticultural and gardening purposes. The bog contains many rare creatures and plants such as bog rosemary and water voles.

The uplands areas include the Berwyn and Ruabon Mountains with blanket bog and heath and support black grouse.

The Wrexham Biodiversity Group meets four times a year and is a partnership of government bodies, groups, charities and individuals.

The group implements the Wrexham Local Biodiversity Action Plan, which they produced in 2002.

Biodiversity Projects which the group is involved in include River habitat enhancement and otter holt construction, pond surveying and management, moorland bird survey and derelict land grassland survey as well as numerous educational and awareness raising projects.
