So what is it with SNH that they should complain that the free beavers of the river Tay in Scotland have not followed the IUCN guidelines? They are, after all, only guidelines, not protocols.
Now, here is a sight that mystified me. I think that an otter has played around. By the time that I saw this the temperature was rising and the ice was turning to slush.
In the meantime we learn that a 'volunteer' has been appointed to trap the beavers in the Tay. It seems that a particular lodge has been marked for the trapper's attention and SNH's spies have ascertained that it is occupied by one adult and two yearlings. The lodge is said to be near Blairgowrie which, I suppose, means that the lodge is on the river Ericht, a tributary of the Isla, itself a tributary of the Tay.
Here is that same pool a couple of days later.
Here is an email from my excellent friend, Jean-Pierre Choisy, ecologist for the Parc Regional of the Vercors.
