The variation in height growth was apparently explained by the capacity of the plants to acquire nitrogen because shorter plants had lower concentrations of foliar N than did taller ones.

Regeneration, Growth, and Sustainability of Mahogany in México’s Yucatán Forests Assuming constant growth, a big-leaf mahogany requires 122 years, on average, to reach the 55-cm minimum cutting diameter, although the fastest-growing trees may do so in 82 years. The current selective harvesting system, based on a 25-year cutting cycle, cannot be expected to ensure sustainable ha

Silvicultural Systems for Big-Leaf Mahogany Plantationswood system in Sri Lanka and a group selection system in St. Lucia have been more carefully developed. The proposed systems are described in detail. Successful long-term management of big-leaf mahogany plantations depends on choosing a system that accommodates both the light requirements of the spec
