2012 seems to have been a bit mixed for dormice around the
country but at Monkwood it’s been one of the best years yet!
Things started well with a successful grant from Peoples
Trust for Endangered Species to help pay for 65 new dormice nest boxes to
follow up a tube survey of the perimeter of the wood in 2010-2011 that found
signs of dormice all around the wood.
10 of these boxes were used to replace some existing worn
out or squirrel-damaged ones at the north end of Monkwood and the rest enabled
us to set up a new run of boxes in an area of younger growth at the south end
of the wood. The new boxes went up at the end of March and had only been up for
a few weeks before we found a torpid female dormouse during our check in June.
Dormice hibernate fully during the winter but during the
summer, and particularly during spring when there is less food around, they can
go into a deep sleep known as torpor to save energy and so are often found fast
asleep at this time of year. After a couple of minutes in the hand they will
start to wake up but sometimes are relaxed enough to go back to sleep again!
Instant winner of the ‘Cutest animal in the wood’ award!

In August we found just one female dormouse in the same box
as 2 months earlier but showing little increase in weight and we began to
suspect that all the rain was keeping the dormice in at nights and affecting
feeding and breeding.
We needn’t have worried though - by September the dormice
were back and we found a few more nests
and two males and one female in another of the new southern boxes. All
three were a good weight for the time of year and beginning to fatten up for
hibernation. Judging from the weight and fur colour, one of the males was a
juvenile born earlier in the year and a good sign that some young were being
born and finding enough to eat.

This was all confirmed last week in our October check. Apart
from a few nests we didn’t find any dormice in the southern boxes but found
three juveniles in one of the northern boxes. Again these were all at a good
weight ready to go into hibernation in the next few weeks.
Many thanks to PTES for funding the new boxes and to all
those who have helped with the checks this year. Particular thanks must go to
the Trust for the management work during the last few years as the regenerating
scrub patches provide excellent dormouse habitat and the population seems to be
responding accordingly.
Hopefully 2013 will be even better.
