Beavers
Beavers are fairly common in parts of Poland, and on a recent recce visit (report here) there I was lucky enough to be taken to see a beaver and to see evidence of where they are active.
Beavers get going at dusk, which is why the picture to the right isn't that clear, but the evidence of their activities was. It was a pond near a farm, with a small viewing screen to reduce disturbance to the beavers, which were plainly encouraged.
To see a beaver was terrific, but an equally fascinating experience was to see an area of flooded woodland in the celebrated primeval forest at Białowieża (below).
We couldn't see beavers: it was daytime, after all, but there was plenty of evidence. A beaver dam here - you couldn't get near it - has raised water levels, creating a sequence of pools and killing many trees. We found a footprint. But the pictures below and bottom right show the most obvious signs of their presence.
Dead timber - standing or fallen - is well-known for its value to wildlife so there's no doubt in my mind that the beavers here have created a network of valuable micro-habitats. We chanced across a wild boar piglet drinking. Dozens of ruddy darter dragonflies buzzed around: this one settled.

There are more pictures of Białowieża forest here.
There is also a chance to see beavers on our Cévennes holiday, where there is a reintroduction project on the river Dourbie.
Should beavers be reintroduced to the UK? Sure!
