The park is a mainly grassland area with a small wood, hedgerows and two play areas. Deans Brook, which crosses the park, has been dammed to create an ornamental lake. The lake has a fringe of vegetation dominated by great and lesser reedmace. Coots, moorhens and mallards breed on the lake, and it also supports amphibians and dragonflies.
The woodland of oak and hazel is clearly old, as are some of the hedges, and there are plants indicative of ancient woodland, such as wood-sedge. Parts of the grassland are herb rich, with wild flowers such as cuckooflower.
There is access to the park from Edgware Way, Fairmead Crescent and Riverdene.
Stoneyfields Park and Deans Brook are a Site of Borough Importance for Nature Conservation, Grade II.
