INVERTEBRATES
The variety of habitats within the site has resulted in a wide range of invertebrates, including species found in woodlands, open grassland and wetland areas.

FISH
The pools and small lakes close to the southern edge of Cliffe Wood contain Carp, Perch, Bream and Tench.

The River Dearne, at one time one of the most polluted rivers in the region, now has greatly improved water quality and supports Brown Trout.

The variety of both wooded and non-wooded areas on the site supports a wide range of bird species including Collared Dove, Cuckoo, Green Woodpecker, Wren, Mistle Thrush and Treecreeper. In addition, the area supports Song Thrush, a declining species.

There is a wide range of warblers, including Whitethroat and Lesser Whitethroat, Garden Warbler, Blackcap, Chiffchaff and Willow Warbler; and a variety of tit species including Great Tit, Blue Tit, Long-tailed Tit, Willow Tit and Coal Tit. Finches found on the site include Chaffinch, Greenfinch, Goldfinch, Linnet, Redpoll and Bullfinch.

Birds of prey that search the area for food include Sparrowhawk and Kestrel. Mown grassy rides, which are a favourite haunt of Magpies and Jays, occur in many parts of the site.

Mallard, Coot and Moorhen are permanent residents of the pools and small lakes close to the southern edge of Cliffe Wood, and Kingfisher can be seen along the course of the River Dearne. Other bird species associated with the lakes and other wetland areas on the edge of the wood include Little Grebe, Great-crested Grebe and Canada Goose.

MAMMALS
The Oak/Birch woodland is rich is wildlife, including Fox, Rabbit and Grey Squirrel, the latter feeding on acorns.

The mixed plantation area in the west of the site provides an ideal habitat for mammals such as Wood Mouse and Bank Vole.
