Bats!  Petersham Common provides a link for bats moving from roosts in Richmond Park to feeding grounds along the River Thames.  Bats follow critical flight paths that link protected sheltered spaces (trees, hedgerows, no street lighting) and we have 6 bat boxes on the Common (along with about 75 bird boxes).  We hope to carry out bat surveys with the London Bat Trust in 2021 to better understand the importance of the Woods to bats.  This requires licenses from DEFRA and includes catching and placing micro GPS trackers to understand their movements.  The trackers fall off the bats after a few days.  In this context if you are a night owl and like staying up all night to monitor bats then please make contact.
