Last Sunday, before social-distancing rules really kicked in, H and I went for a walk down to the Dubh Loch in Knapdale, just to see what the beavers had been up to over the winter. Answer: plenty. Here are some photos of what was easily-seen and which shows examples of beaver signs for those who’ve not seen them before.
Yes, busy as as beaver is a thing.

The beavers’ technique for building dams shows well here, where they’ve reinforced the Dubh Loch dam.

This whole area is flooded, or at least much wetter, than it was before the beavers dammed the Dubh Loch. Standing trees have died and are falling, opening the whole area up.

This ditch has been used by the beavers as a canal – in fact, it has been dammed further along to improve it. They’ve been feeding on some of the sticks here at the end of it.
