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 Castle, flanked by two large information posters, and beside it is a copy of B-P's footprint. In May 2000, twenty trees were planted, one for each boys who attended. During the planting ceremony, the Scout Chief Commissioner for England, along with representatives of the Scouts and the Guides, planted the trees on the seaward side of the original site. The trees were designed to act as a permanent memorial to the camp, as well as providing a series of future windbreaks against coastal winds. After the death of owner Charles van Raalte in 1907, his wife Florence stayed on Brownsea
