Cheers for the report.
Definitely a privilege to visit that site far away from everything and where you wouldn't really expect to see adders. I've visited it a couple of times while sampling Zootoca populations and recognise the locations in the photos. The adders are huge and the largest I saw was 86cm and 260g. I really like how some have a very wide zigzag pattern.

Cheers

Hello Martti, I think you met some people on the last expedition in 2005 or 2006?
The mentioned they met you when looking for Zootoca.

86 cm is huge, was that a female?
Maybe its a bit hasty to conclude that there arent any 1m giants.... After all we only had about two and a half days with good conditions and "only" found about 20 snakes.

regards

Jimmy

20 adders in 2 days ? that´s really amazing , as they have less natural predators , they behave like other adders when they see people, or you can get closer ?

They often bask in the open, probably because lack of many predators, so sometimes its possible to get close. And due to colder climate maybe they are forced to expose themselves to the sun, instead of basking under vegetation. We saw some snakes with injured tails, and according to Stefan the odd fox, marten or eagle maybe can take a snake for prey, but many snakeeating predators for example buzzard is absent this far up north.
