BBC2 today had 45 minutes about beavers in the Tetons Nat Park and their management problems. Blocked road culverts and waterlogged areas due to flooding across land with gentle gradients and the beavers put in a 3 or 4 foot high barrage across. Sequences of ponds have no effect on reducing flooding in winter as you simply have a series of filled up baths leading one to another. Having a spate is just turning up the tap into bath one and the flow goes down the system uninterupted.
While the landowners hate them, beaver ponds are often very good fishing. In the summer when stream flow diminish or completely dry up , beaver ponds often offer the only deep cold Water for fish to reside in.

The Knapdale trial has hardly been a great success. First group imported and there were prerelease losses in quarantine. 16 remaing released in 2009/10 and 8 died within six years. In 2016 the RZSS said that there was a serious risk to those remaining dying out so reinforcements were brought in from the flourishing but illegally released Tayside population. 17 were moved over and of those 5 have died and one cannot located and is missing, probably dead. So 6 out of 17 of group two have gone inside of three years.
Some about to be released into enclosed 35 acres by NT back end of Haslemere. Streams are quite small in that area....but are many large ponds created from streams by landowners. Hmm.

The NT will not manage to contain them, or activists will cut the fencing. What consultation took place with neighbours?

Not a lot one would imagine. I watched the beeb2 documentary, one of the concerns expressed by the landowners it featured was the threat to specimen trees posed by beavers. A pair of beavers can cut down up to 200 trees a year which doesn't sound too good for riparian habitat in the kind of heavily modified, managed river environments the UK contains.
