the high venn's plateau thus is rich in flora and fauna some of which have become rare and threatened in the last more than three centuries. the heathers and turf moors in the reserve have a significant role to maintain biodiversity for the rare and threatened flora and fauna as it ensures regulation of the water balance and maintains value of the landscape. however, since the 17th century, peat cutting, drainage, inappropriate spruce plantations, infestation of the ground by the purple moor-grass, a herb, had caused problems for the ecology of the region. these negative aspects are now being rectified by special projects titled "life-nature project".
