Bohemia Bog is one of the most important botanical sites of the Island. It is a transition mire of little over 0.1ha and is believed to be the only site on the Island where Pale Butterwort is found and the carnivorous Sundew is also present. In recent years this unique habitat has been disappearing under bramble and gorse. However, now thanks to the intervention of the Hampshire and IW Wildlife Trust the scrub is being removed to enable the sympathetic management of the site for its wildlife value.
