Short History of the site
The arboretum site is located in the Sintra Cascais Natural Park. The terrain is public property, administrated by Parques de Sintra Monte da Lua (PSML). PSML showed great interest when presented with the possibility to install the proposed structure. Collaborating with PSML, which has several ongoing projects in forestry research and environmental education, allows for the structure to be properly maintained, for educational and REINFFORCE research porpuse,. The arboretum is divided in 2 groups of parcels, located inside 2 walled sites : -P1, in Tapada das Roças previously occupied by Acacia sp. and Pitosporum undulatum.; -P2, in Tapada do Mouco, previously occupied by Eucalyptus globulus, Acacia sp. and Pitosporum undulatum. Soil preparation for arboretum installation was initiated in June 2012, consisting mainly in cutting Acacia sp., Pitosporum undulatum, and spontaneous vegetation removal/ control.
