Switzerland: introduced Dice Snakes
![Post Post](./styles/prosilver/imageset/icon_post_target.gif)
Saturday I have been at the SIGS (Swiss tortoise and turtle association) meeting in Luzern.
Sunday morning we visited the introduced Natrix tessellata population at the northern banks of lake Alpnach.
Before a few years, when they start to build the walking and biking trail they have made a counting, marking, capture and recapture and came to a result of approx. 2´000 snakes.
Nowadays there are a lot more.
and there will be many more in future..........
also the Podarcis muralis are introduced!
