One Percenters at Beddington Farmlands
Green Sandpiper (Up to 1% of the British wintering population is hosted at Beddington)
The latest British Birds (Vol 104) contains the most recent overwinter population estimates of British Waterbirds with new 1% threshold figures. If an individual site contains 1% or more of a species wintering population then it is of conservation significance. At Beddington there are three species that fall into this category.
Greeen Sandpiper (1% threshold is 9): Upto 11 in the winter of 2007 (last published bird report)
Caspian Gull (1% threshold is 1): At least 4 in the winter months of 2007.
Lesser Black Backed Gull (1% threshold is 1,200): Highest count of 2580 in March 2007.
