The New Forest Act 1877 confirmed the historic rights of the Commoners and prohibited the enclosure of more than at any time. It also reconstituted the Court of Verderers as representatives of the Commoners (rather than the Crown). Felling of broadleaved trees, and their replacement by conifers, began during the First World War to meet the wartime demand for wood. Further encroachments were made during the Second World War. This process is being reversed in places, with some plantations being returned to heathland or broadleaved woodland. Rhododendron remains a problem.
