Silvicultural Systems for Big-Leaf Mahogany Plantationstle account of the long-term development of stands or subsequent rotations and cannot properly be called silvicultural systems. As existing plantations begin to mature, the need to consider establishing the next rotation grows, and, therefore, the need to adopt a suitable silvicultural system. Where

Structure and Dynamics of Mahogany Plantations in Puerto Ricoincludes nine plantations at seven sites from dry to wet life zones, two soil parent materials (limestone and volcanic), three plantation designs (block, line, and taungya), and plantation ages from 18 to 64 years. Mahogany grew well regardless of plantation design or soil parent material but the sp

Mahogany Planting and Research in Puerto Rico and the U.S. Virgin Islandsmall-leaf mahogany on St. Croix, Virgin Islands, were in about 1790. Big-leaf mahogany was apparently introduced in Puerto Rico in 1904. The Pacific coast mahogany, arriving much later, has not performed well and grows only in research plots. The hybrid between big-leaf and small-leaf mahogany was f

Genetic Variation in Natural Mahogany Populations in Boliviad; the multilocus outcrossing estimate was . = 1.038 (SE = 0.024). Mahogany thus con forms to the model emerging from other genetic studies of tropical trees: a long-lived woody species, with a highly outcrossed breeding system that generates the potential for significant pollen movement, and high v

Twenty Mahogany Provenances Under Different Conditions in Puerto Rico and the U.S. Virgin Islandsal breadth observed in the species of mahogany. Although most of the variation was caused by environmental effects, phenotypic plasticity was not adaptive for the traits examined and thus possibly did not contribute to the species ecological range. These findings suggested a strategy for conserving

Hurricane Damage to Mahogany Crowns Associated with Seed Sourcell-leaf mahogany and the northern sources of big-leaf mahogany were the most resistant to storm damage; Pacific coast mahogany and the southern sources of big-leaf mahogany were most affected. Crown recovery, measured by change in percentage of the estimated full crown complement over the 4-year per
