From john at lawton.me.uk Mon Apr 4 11:51:01 2016 From: john at lawton.me.uk (John Lawton) Date: Mon, 4 Apr 2016 11:51:01 +0100 Subject: [Announce] Cam Valley Summer Walk Tuesday 24 May Message-ID: <57024715.4070506@lawton.me.uk> From the Cam Valley Forum: Dear Members and Supporters, You are warmly invited to join us on *Tuesday 24 May at 6.30pm* for a walk along the *Bourn Brook*. Our leader will be *Vince Lea of the Country Restoration Trust* who is exceptionally well placed to show us its state in the modern world. *The starting point will be at grid reference TL40605461 which is just south of Barton where* *the minor road to Haslingfield has branched off the A603 and crosses the Bourn Brook itself.* *Vince writes that *we will proceed westwards along the north bank, with a detour to look at features on the south bank. There is about 2km of brook in that direction, so plenty to look at, and anyone who wants to turn back at any time can do so. As usual with rivers, we have to do the same route out and back! We shall see some of the problems created by dredging the course of the brook in the past - there is an old meander loop which has been left high and (usually) dry, but we have added cobblestones to the dredged channel to raise the level and oxygenate the water. Around the course of the Bourn Brook, all farmland has been restored to hay meadows, reducing siltation and runoff into the watercourse. There are many veteran willow pollards which we are restoring. Depending on how far people can manage to walk in a couple of hours, we should be able to get to the more distant reaches where a few Black Poplars have been planted. It is likely that Himalayan Balsam will be starting to show itself in places, despite our efforts to control it. Along the Bourn Brook there is still a lot of seed resources keeping it going. I will also show the mink rafts and the latest technology in trapping. Assuming it's a nice evening we are very likely to see Barn Owls towards the end of the walk, Kingfishers are always a possibility, and otter signs. Some invertebrate sampling if participants are interested. *To help with planning it would be a great help if you would kindly reply to this email (if the idea of the walk appeals) to register an interest.* With thanks, David Brooks From john at lawton.me.uk Mon Apr 4 11:51:01 2016 From: john at lawton.me.uk (John Lawton) Date: Mon, 4 Apr 2016 11:51:01 +0100 Subject: [Announce] Cam Valley Summer Walk Tuesday 24 May Message-ID: <57024715.4070506@lawton.me.uk> From the Cam Valley Forum: Dear Members and Supporters, You are warmly invited to join us on *Tuesday 24 May at 6.30pm* for a walk along the *Bourn Brook*.
