Short History of the site

The arboretum site is located in Universidade de Trás-os-Montes e Alto Douro (UTAD) terrain, administrated by the University. , which showed great interest when presented with the possibility of installing the proposed structure. UTAD is engaged in forestry research and teaching, so this collaboration will guarantee that site management and monitoring tasks will be performed more proficiently. The arboretum is divided into 2 parcels, separated from each other by a 3m wide dirt road. The parcels are: -P1, 1,5 ha, previously occupied by Castanea sativa stand and pasture, with seasonal water line running through it ; -P2, 1 ha, previously occupied by Pinus pinaster stand. Soil preparation for arboreta installation was initiated in December 2011, consisting mainly in cutting the C. sativa and P. pinaster trees, and spontaneous vegetation removal/ control. Site was used for forest production and pasture.
