Sevenoaks Gravel Pits

Sevenoaks Gravel Pits is a 73.7-hectare biological Site of Special Scientific Interest on the northern outskirts of Sevenoaks in Kent. It is managed by Kent Wildlife Trust as the Sevenoaks Wildlife Reserve and Jeffery Harrison Visitor Centre.
The site was converted from gravel-pit to nature reserve by the Harrison family - particularly Jeffery Harrison, after whom the visitor centre is named. As such, the site is almost totally man-made - nearly all trees on the site were manually planted, and the lakes and ponds were created by excavating and flooding former gravel workings with water from the River Darent. As such, the site represented the first such conversion of a gravel-pit anywhere in the United Kingdom.
