You are now entering the Alderney Recreation Ground which provides 15 hectares of open space within a suburban environment.
The site is bordered to the north by the Bourne Valley Local Nature Reserve, which has national and international conservation designations.
Water flows into the pond from woodland streams and is then piped under the Recreation Ground.
The pond is important for amphibians, supporting large numbers of common frog, smooth newt and palmate newt. Ponds throughout the Bourne Valley are very important for dragonflies and damselflies.
The woodland is fairly open and dominated by willow, which likes the wet conditions. The stream runs through the woods and contains plants such as pondweed.
