During both World Wars, many civilian women took up jobs in agriculture, replacing those men who went to war. The women who worked for the Women's Land Army (WLA) were commonly known as Land Girls. In forestry, Women's Timber Corps were known as Lumber Jills. At the height of the First World War the Land Army had a full-time membership of 23,000 members. The number exceeded 80,000 during the Second World War.
