The photographs have not installed themselves quite as I had planned. 'Before' should have been above and 'After' should have come below. But there it is. The brisk wind from the North-East took those two stems of the birch tree in the end. I wonder how long it will be before the third trunk goes. I took the photograph to the left of the two shots of the beaver pond on my way to the Burnieshed Two, the wild boars that are still living in the Den there. What a splendid example of a snag. As you can see, it is pockmarked with holes that a woodpecker has drilled.
The day before yesterday Professor John Thorpe, a retired fisheries' biologist with a special interest in salmon, came to visi . This was a most rewarding visit for me because here was was someone with a very keen ecological understanding. Not for him observations about impacts and damage done to trees by beavers, but instructive remarks about the dynamic nature of the riparian ecotone and the importance of dead wood for biodiversity and productivity of the freshwater ecosystem.
