3 October 2009, Belair Park, London
OPAL teamed up with New Leaf to carry out some air surveys in Belair Park.
New Leaf was founded in 2005 by Vinnie O'Connell. It works with young offenders and encourages them to get more involved in nature.
The group has spent the last few years reviving a derelict strip of railway into a unique garden and museum dedicated to the swedish naturalist, Carl Linnaeus.
