Predator management is key at Kingfishers Bridge. Small numbers of predators can quickly decimate ground nesting species, especially waders. A predator fence surrounds the the Cam Washes SSSI and 150 acres of the main wetland Project. The fence has a primary structure of stock fencing but with rabbit netting clipped to it reducing the access size to 25mm. The rabbit netting folds out at the base to form a skirt preventing burrowing animals digging underneath. Live electric wires at the top of the netting and at 15cm intervals above it prevent predators climbing or jumping the fence. Whilst primarily designed to be a fox deterrent fence it is extremely effective against all ground predators with the strength to exclude badgers and the fine tolerances to limit predators as small as stoats. Corvids are also controlled at Kingfishers Bridge. Magpies are prolific egg thieves and are controlled through the use of Larsen traps in the spring before wader breeding starts. Carrion Crows will predate wader chicks and eggs if they get the chance, numbers are controlled through the use of ladder traps or shooting with silenced rifles.
