This cache is the third of our "Around Middleton" hides, and is placed with the kind permission of Derbyshire Wildlife Trust.
Please heed the following:
- the nature reserve is a Site of Special Scientific Interest and also a Special Area of Conservation under European Law - please respect as such. The cache does not require anything to be disturbed or climbed over.
- stick to the designated, obvious footpaths in the area to avoid mineshafts; these are normally capped, but may be liable to soil movement.
- dogs to be kept on leads in the reserve.
Perched high on a hillside above Cromford and Wirksworth - Middleton is a village with a long history of mining and quarrying.
It is surrounded by the scars of industry yet steeped in history and bursting with community spirit.
Founded in Saxon times as a farming hamlet around an unusually high spring, the village developed in the 17th and 18th centuries as a lead-mining centre (like nearby Wirksworth) and a few of the older buildings in the upper part of the village date from this period.
This reserve is part of an ancient lead mining area.
The name Gang Mine comes from the word 'gangue', meaning waste, for the waste minerals which were dumped around the shafts. The lead spoil heaps are of little agricultural use, and only a small number of plants are able to tolerate the high concentration of minerals.
Among the species that thrive here are the nationally rare spring sandwort, and alpine pennycress. Both are locally known as leadwort. The lead spoil grades into other open areas. In some, lichens dominate the ground cover, while in others colonising species such as kidney vetch and thyme dominate. These open areas provide ideal conditions for ground-hunting invertebrates such as wolf spiders and ground beetles.
Away from the lead spoil heaps the habitat is mostly unimproved neutral grassland with a variety of flowers such as yarrow, mouse-ear hawkweed and bush vetch and occasional pyramidal orchid. The dew pond, a traditional drinking place for livestock, has been restored and adds an interesting feature to the reserve, providing permanent water, a valuable habitat for amphibians including the rare great crested newt.
Metal-rich grasslands such as Gang Mine are uncommon across Europe and because of this the area has been designated not only as a Site of Special Scientific Interest but also under European Law as a Special Area of Conservation.
