Chairman’s Letter Suffolk Wildlife Trust’s Chairman Magazines Out of the blue I had a call from the new Chairman, Sir A special word of thanks goes out to our magazine Kenneth Carlisle who said he was trying to meet all the distributors and deliverers who manfully struggled with groups and as he couldn’t make our AGM, could he the above mentioned book which created an extra thick come to meet the team. I readily agreed and he sat in on and weighty envelope which declined to go through and contributed to our next committee meeting. I think many an older style letterbox. Don’t despair though as it’s good that he wants to be involved and not just be a you will be pleased to know that forthcoming issues will figurehead. be even lighter than previously, as the Natural World has been dropped with only extracts going in our Wildlife AGM magazine. The AGM came and went with the election of the same Suffolk Show committee; no new (young?) blood came forth to drag us screaming into 2012! I hope many of you managed to go to the Suffolk Show and to visit the SWT marquee and wildlife area.

Dave Munday 4 Ipswich Group Newsletter Alton Water 21st May, 2011 by Harry Price When Ipswich became short of water in the 1960’s it was decided to create a new reservoir between Tattingstone and Holbrook. In 1978 a bridge at Lemons Hill was built Mike Ewart to avoid the village of Tattingstone being split in two © once the reservoir was filled. It was here that a party from Ipswich SWT met up with members of the Shotley Peninsula SWT group to be taken on a guided tour, led by members of the Shotley group. Ann, Alison and Mike are enthusiastic volunteers, eager to explain the work done by themselves and others to monitor and care for the natural environment of the area covered by the water and its surroundings, which are owned and administered by Anglian Water. The lake is ringed by a surfaced path, some eight miles long, for walkers and cyclists. There are also side paths leading to the water’s edge and to observation hides, The new hide at Alton Water specially constructed by the volunteers for Alton Water is a naturalist’s paradise. What until 33 years ago was farmland has now developed into areas of woodland, The water itself is never far away. The eastern end is carefully managed so as to leave places of bushy available for (non-motorised) water sports such as sailing undergrowth, beloved by nightingales (we heard a and wind surfing, but the middle and western parts are couple).

The shore- © Mike Ewart line is punctuated by many narrow inlets, where Greylag, Canada geese and Great Crested grebes abound. In one such inlet an unusual ripple in the water revealed a grass snake swimming into the shelter of the reeds. Alton Water is of course man-made, and the numbers of cyclists and walkers along the track as well as the well-filled car park at the Visitors’ Centre testify to its popularity, so human pressure on its environment is considerable. But none of this detracted from the peace and beauty of the area and we were greatly impressed by the continued work being done by the volunteers as well as Anglian Water to make this a lively and viable wildlife habitat. Our thanks go to Pam Ireland and our guides for setting Volunteers constructing a floating raft for nesting Terns up a delightful and fascinating afternoon. see www.altonwildlife.co.uk 5 Ipswich Group Newsletter The Wall - a butterfly we are losing from the Ipswich area by Rob Parker, Butterfly Recorder for Suffolk The Wall, or Wall Brown, Lasiommata megera, has been allocated to the UK BAP category of ‘Research Only’, in recognition of the inadequately understood decline of this formerly common resident. Over the past 30 years it has lost 38% of its UK distribution, following a similar Stephen Hammeersley pattern to the Grayling and becoming more coastal. In © Suffolk it is no longer found as a garden butterfly in the centre of the county and is retreating eastwards at an alarming rate. There have been occasional records from the Rushmere, Bixley and Purdis Farm areas over the past five years but sightings have been very thin around Ipswich in the past three years.
