O Sobreiro(1991)

This documentary, having as its central character the cork tree, aims primarily to stir universal interest in saving and preserving nature, by pointing to the important role that a tree may play on a people’s identity. A wide variety of themes are covered, including the tree’s biology and phylogenesis; the ecosystems, with which it is associated; the animals that support it; its evolution and ecological contribution to its habitat; the symbolism that has inspired astists, poets and writers; the economic and cultural factors that have regulated its expansion, and are currently placing the species in jeopardy... Accompanying the cork tree during the four seasons, this documentary portrays a version of Portugal’s history and the culture of its people.
