Fifty-two boxes were surveyed once a month April to November, contents recorded and registered with The County Ecologist, SeWBREC, NRW and NDMP. Early in the season Tits had nested in 22, 42% of boxes, this year there were Slugs many boxes and in October one box contained 6 Woodmice.
Our heaviest Dormouse, in October, was 31gms (a good hibernation weight) and the lightest, June, a group of four grey young with their eyes just open which weighed together were found to be 28gms, an average of 7gms.
Our numbers, May/Nov, had been going up 2009 ~ 33, 2010 ~ 89, 2011 ~ 108 but the 2012 figure is only 41. This decrease has been mirrored across much of the country due to the inclement weather.
