In the decade before the war the Forestry Commission took practical steps to meet the increasing needs of the population for large tracts of wild country to be put at their disposal for recreational purposes by establishing Forest Parks, the first such Forest Park being that of Argyll, created by the Forestry Commission with the co-operation of Glasgow Corporation in 1936. Other Forest Parks in Wales and England followed shortly afterwards; Snowdonia in 1937 and the Forest of Dean in 1938; and several others have since been established. Dartmoor National Park was created in 1951, with its bound aries extending well beyond those of the ancient Royal Forest of Dartmoor and the adjacent open moorland and commons.
