But for volunteers and staff, maintaining these perfect conditions is a full-time challenge. Every Wildlife Reserve is important – and the Island’s Ningwood Common is no exception. In fact, as the only home of the last remaining natural population in Britain of the rare reddish buff moth, it holds a unique place among the Wildlife Trust’s reserves. The reddish buff moth thrives on Ningwood’s warm heathland, making the most of its fairly short sward and high density of sawwort, the food plant of the caterpillar. The current challenge is to ensure these favourable conditions continue to exist. To maintain this vital habitat takes significant human endeavour as well as careful management of the other species likely to call Ningwood home.

These hardy beasts will help break into the scrub and browse the thorny new shoots and tough aggressive grasses that encroach onto the best areas for the moth. Aside from the reddish buff moth, other important species found on site include small pearl bordered, dark green and In the past nightjars were regularly recorded on the heathland. However, as Ningwood became a regular area for local dog walkers, the dogs frequently flushed the birds and they eventually disappeared. Even though they are on the decline generally throughout their range in Britain, it is hoped that better control of dogs and the extension of more suitable habitat through the scrub clearance may encourage nightjars back to Ningwood.
