Habitat

About

Bolton-on-Swale has been landscaped and allowed to flood to provide suitable habitat for many wetland bird species. Tree planting and scrub along the lake margin has further diversified the site for birds. During the winter months the number of ducks and wading birds increase and nationally important numbers of wigeon use the site. The wigeon are joined by goldeneye, pochard, tufted duck, lapwing, golden plover, teal and shoveler. The wetland can attract some interesting passage migrants such as green sandpiper, artic and black terns, greenshank and ruff in late summer/autumn.

The grass is grazed short by sheep belonging to a local farmer, assisted by a large mixed flock of greylag and Canada geese.

The large islands in the lake have mainly been overtaken by bushes and trees. Clearing will provide nesting opportunities for wading birds such as oystercatcher which already here, and encourage other species. Great crested grebes, coots and moorhrens all breed around the lake.

The site is managed by a tenant farmer but access is provided via a path leading to two hides providing views over the main lake.
