WILDLIFE AND CONSERVATION North of Hartington, the river Dove follows the boundary between the limestone (on the Derbyshire bank) and the shales (on the Staffordshire bank). This affects the vegetation and wildlife, so that different species can be found on each side of the river. South of Hartington, it is in the limestone dales that the most varied and interesting wildlife is found.
Dovedale Wood is one of the best ashwoods in the country (but not open to the public). Ancient woodlands like these have much more wildlife value than plantations or other new woodland. Rocks and screes which have resulted from the effect of frost on the cliffs above, have developed specialised flora with mosses, lichens and flowers such as Herb Robert. If movement stops, eventually screes become flower rich grasslands, or woodland, with a great variety of attractive flowers. The flowers encourage a range of insects including butterflies and moths. The best grassland has been maintained by sheep grazing. The reduction in sheep grazing in some dales over the last 100 years has allowed scrub (shrubs such as hawthorn) and long grasses, to grow. The National Trust have cut back shrubs which hid famous rock features and have re-introduced sheep grazing. One area that has recently been cleared is around the Twelve Apostles (famous rocks). On the shale area north of Hartington, the cuckoo flower is common on the grassland. This provides food for the caterpillars of the orange-tip butterfly. Herons often feed in the quiet, northern stretches of the river. Trout, dippers, grey wagtails, moorhens and water voles can be seen in, on and by the river. |
