Two other spectacular and scarce species occur locally, the Purple Emperor and the Silver-washed Fritillary.
Two fields at the top of Tilletts Lane are the focus for our conservation efforts, with all the priority species having been sighted there, making the site of both County and National importance. In all, 33 species of butterfly have been recorded in the Tilletts Lane Butterfly Fields. A full list can be found here
With the kind permission of the landowner, Jonathan Lucas and tenant farmer, Dominic Gardner, these fields have been informally set aside from agricultural use so the site can be monitored and managed for butterflies.
Since 2010, regular surveys have been conducted on a weekly basis between April and September to record numbers, locations and species of flying butterflies. The results of these surveys are submitted to the National Butterfly Conservation database.
Although the primary focus is on butterflies all local fauna and flora are being encouraged, so in 2011 the Warnham Society helped fund the erection of a new Barn Owl box on the site.
