 The first conifer plantations were planted at Wentwood in 1880, and most of the native trees were felled during World War I to provide timber for props and supports for the trenches.When the area was replanted by the Forestry Commission in the 1950s and 1960s, the original broadleaved deciduous trees were largely replaced with non-native conifers, damaging the woodland habitat.More recently, broadleaved trees have been allowed to grow back.
