About the reserve
The area of mixed woodland and grassland clearings known as The Warren is abundant in dragonflies thanks to the large pond and wetland area nestled in its centre.
The reserve is composed predominantly of oak and silver birch woodland on sandy soils with rhododendron, and with a ground flora of bracken and wildflowers. It was once part of Kevington Manor Estate.
Near the railway cutting to the north of the site, some small areas of acid grassland are home to rare London plants.
