Butterflies are indicator species. This means they can be used to monitor the health of the local environment, and also govern how you manage a site for wildlife.
A Butterfly Transect has also been set up at Harmony Woods, a site owned and managed by Andover Trees United (http://www.andovertrees.org.uk/Andover_Trees/Home.html).
All this data feeds into Butterfly Conservation (http://butterfly-conservation.org/). If you wish to take part in the local surveys please contact us for more details.
