An update..I note from numerous accounts on a Yateley Facebook page that adders are making themselves known on the Common and also on the northern side of the airfield between the runways. Breedings seems popular at the moment, amid the adders, apparently numerous dogs have been bitten some fatally. Staying at home I've missed my walks on the sadly disused runways but recall vividly almost treading on an adder on one of the numerous pathways through the tangle that much of Blackbushe grown into. Beware, they've got sharp teeth!!
