Brownsea Island It is within the South Dorset constituency of the House of Commons and the South West England constituency of the European Parliament. Brownsea Island has built up on a bare sand and mud bank deposited in the shallow harbour. Ecological succession has taken place on the island to create topsoil able to support ecosystems. The nature reserve on the island is leased from the National Trust by Dorset Wildlife Trust. This reserve includes a brackish lagoon and area of woodland. Other ecosystems on the island include salt marsh, reedbed, two freshwater lakes, alder carr, coniferous woodland, deciduous woodland and arboretum.
Brownsea Island Scout camp by Olave Baden-Powell, when the island became a nature conservation area owned by the National Trust. In 1973, a Scout Jamboree was held on the island with 600 Scouts. The worldwide centenary of Scouting took place at the Brownsea Island Scout camp, celebrated on 1 August 2007, the 100th anniversary of the start of the first encampment. Activities by The Scout Association at the campsite included four Scout camps and a Sunrise Ceremony. Named after this one, there is also a Brownsea Island in The Summit Bechtel Reserve in West Virginia, USA, a training, Scouting, and adventure centre. Robert Baden-Powell
