A mature forest of pine, cypress, eucalyptus and other non-native trees covers the higher areas of the Presidio. The army planted these trees from the 1880s through the 1940s in order to make the area appear larger with more relief, to limit visibility within the Presidio, and to beautify the post. Signature groves of the planted cultural forest are being maintained and replanted as the old trees die or blow over, but native plants are also being restored to outlying areas where the forest has expanded out of its original boundaries.
