... are they actually as dangerous as i was led to believe they were when i was a kid?
With most wildlife there are probably a lot more of them around than you think.
Unfortunately, from my trips around the country collecting adder DNA this year, they are on a sharp decline and in a much worse situation than we first thought. These heath fires have also wiped out entire colonies which were once rich strongholds for them.
... small populations are not sustainable genetically. They are also being isolated to small pockets within large areas of wilderness because of heathland restoration projects and RSPB clearance schemes. ...

Yeah - I saw Upton Heath got toasted. I lived nearby in Lytchett Matravers for about a year and arson accounted for at least two burns on Upton Heath while we were there. I read that whole populations of lizards were wiped out but I guess Jonathan can confirm/scotch that rumour.
We don't see any adders up here, as they are sensible where weather is concerned...
