Plantation woodlands around Langsett Reservoir first depicted 1967. Earlier maps show probable parliamentary enclosure of Midhope Moors. Date of parliamentary enclosure of land in Midhope uncertain. English (1985, 98) lists an Act of Parliament for Upper Midhope in 1818 but records that "Award never completed". The date of origin of the moorland is uncertain but it had probably developed in this area by the Roman period (see Bevan 2003 for discussion of environmental evidence in the area).
