Continuing with the theme of the athletic beaver, here are some photos I took recently of a fallen sycamore that had been ringed by beavers and had then fallen to a winter wind- note the bottom right hand corner of the picture. The tree fell last winter, I think and is held up against another sycamore that beavers have ringed, but which has not fallen yet. The fallen tree has been barked for a certain distance along its trunk, so you may imagine my surprise when I saw that beavers were still interested in it.
Has a beaver mounted the trunk from the bank?
I think it must have and has then padded up the trunk of the tree.
But what has it won in the way of nutrition?
Lichens here, but what about the lower parts of the trunk that have been gnawed?
Perhaps slightly acidic water gives a vinegary taste? Do slime moulds have a flavour?
