Third Year of Monitoring
~
After a successful 2010 season we went into our third year full of optomism. Recent cold winters and the provision of Nest Boxes providing secure shelter from predators, have combined to show an increase in recorded Dormice numbers.
The 2009 survey found an average of 8.7 dormice per survey, 2010 12.7 and over the same period in 2011 14 dormice per survey.

Box Surveys
~
Eight monthly surveys were conducted, April to November, with the contents recorded and registered with The County Ecologist, SeWBREC, NRW and NDMP. In April Blue and Great Tits had nested in 33 of the boxes a Wren in another with four hosting Solitary Wasp nests. *September's survey had to be curtailed due to rain, 27 boxes were checked. In October 17 boxes were occupied by woodmice. Dormice activity was found in all areas of the reserve.
