Reforestation Success in Central México: Factors Determining Survival and Early Growth
Successful reforestation programs are requisite components of any forest industry; failure to establish new forests can lead to deforestation. The objective of this project was to examine factors influencing reforestation success in Central México, encompassing the Federal District and State of México. Seven plantations, established in 1995 with five conifer species, were monitored for 2 yr. Survival after 2 yr ranged from 15 percent to 86 percent. Most of the mortality was related to human activities, including fire, livestock grazing, and agricultural cultivation. Nevertheless, seedling quality was an important component of both seedling survival and subsequent growth. A minimum seedling diameter of 4 mm (0.16 in.) is required for adequate survival, but the target seedling diameter should be 6 mm (0.25 in.) for Cupressus and 8 mm (0.32 in.) for Pinus to ensure highest survival and growth.
