How to count squirrels

Nature A new project at the Forestry Commission:

"Andrew Brockbank, National Trust Property Manager at Formby, says: "Red squirrels would feature on many people’s list of favourite British wildlife and we hope that this exciting new project may help secure their future. The recent major outbreak of squirrelpox presents a unique window of opportunity for research and the tragic loss of red squirrels at Formby could ultimately provide insights which help red squirrel conservation in the future.""

We used see many, many reds in Sefton Park but now it's all greys, some of them tame enough to greet us looking for food as we leave home.
