The Special Protection Area (SPA) of the Upper Nene Valley Gravel Pits covers both Nene Wetlands & Summer Leys and provides safe wintering grounds for over 20,000 water birds. Open panoramic views are key for several key wintering species such as Lapwing and Golden Plover who are particularly vulnerable whilst roosting and feeding.
In August 2023, lake edges around Dragonfly Lake at the Nene Wetlands underwent reprofiling works to soften the steep sided edges. Steep sided edges to the water may not seem much to us, but to a small wading bird they conceal potential dangers. Predators such as Fox, American Mink and even Otters use this cover to stalk their prey. Re-profiling these steep edges to create a gentler gradient between the lake and the adjacent grasslands allows these birds a wide panoramic view which helps them feel safe. This gradient also provides the perfect depths for increased feeding opportunities.
Fantastically, survey data from Wetland Bird Surveys (WeBS), which is conducted once a month from September to March, has shown a dramatic increase of Lapwing using the area. Their numbers have increased from an average of 70 birds per survey to 209, an increase of 265%! It's great when the benefits of reserves work are expressed in survey data so conclusively.
