About the reserve

This large, ex-gravel pit is made up of a main lake with gently sloping banks, shallow areas of water and ponds, low lying islands, a large scrape and a fringe of reeds surrounded by grassland and wet woodland. This is ideal habitat for wintering birds: goosander, wigeon and gadwall reach nationally important numbers, joined by large numbers of roosting lapwing and golden plover. 

Wading birds use the scrape and the shallow lake margins. Oystercatcher, ringed plover, little ringed plover and redshank stay to breed, while whimbrel, turnstone and common sandpiper often pass through during migration. Numerous pairs of common tern nest in a colony on the islands, so we cut back vegetation each autumn to keep them safe, and every few years we re-profile the wader scrape.

Otters are rare but regular visitors to the reserve, while the taller reeds and rushes around the lake may reveal the ball-shaped woven nests of harvest mice. Sixteen species of dragonflies and damselflies have been recorded here and it is one of the best places to see the uncommon hairy dragonfly, which dances around the edges of Marigold Pond in May and June. Late spring sees hobbies hunting insects over the reserve.

Kim’s Corner, a fragment of species-rich neutral grassland, is a good place to watch butterflies. In late summer, it comes alive with the songs of grasshoppers and crickets. We haycut in summer, followed by sheep grazing. To maintain the open natures of the lake banks, we coppice willow. We also cut back other vegetation and remove encroaching scrub.
