High pruning in CAF introduced. The company has identified El Alamo’s poplar exemplars of two species with conserva- plantations tion problems in the Maule region: Crino­ dendron patagua, which is classified as vulnerable, and Sophora microphylla, which is classified as rare.Dasyphyllum diacanthoides, a typical tree species of the Valdivia Forest, and Nothofagus obli­ qua, representing deciduous forests, are also found in the company’s holdings. Similarly, although the CAF El Alamo holdings are modified environments focusing on forest production, they have a significant diversity of wildlife, with a total of 50 animal species having been recorded. The high diversity of wildlife is basically a result of the maintenance of conservation zones. The company has identified a total of nine animal species in conservation categories: black spiny- chest frog (Alsodes nodosus), Chilean slender snake (Tachymenis chilensis), wreath tree iguana (Liolaemus lem­ niscatus), little grison (Galictis cuja), buff-necked ibis (Theristicus caudatus), Andean gull (Larus serranus), Argentine gray fox (Pseudalopex griseus), four- B.

CONCLUSION Poplar has been cultivated in central Chile and specifically in the munici- pality of Retiro for at least 150 years. During this time plantation practices and management have continuously improved from both the technical and environmental points of view. Since 1913 CAF El Alamo has fully
