Devonshire Road Nature Reserve have a blog which can only be a good thing:
In 1998, a new group of local residents and naturalists formed the Friends of Devonshire Road Nature Reserve, to develop and manage Devonshire Road.
Devonshire Road is open on the last Sunday of every month, from 2pm to 5pm (or dusk in winter). There is also an active group of volunteers who help out on most Wednesdays and Thursdays.
The three or four times I’ve been to the reserve I’ve been amazed at the fact it’s in Lewisham at all, somehow it doesn’t feel like it when you’re in there far away from the hustle and bustle of city life.
With thanks to Michael for bringing the blog to my attention.
