摘要：

Diameter and height measurements of alder (Alnus jorullensis syn. A. acuminata) were taken in 16 stands of known age in sierran Ecuador. Stem volume was estimated based on these measurements and an empirical equation developed in Costa Rica. An empirical relationship between stem volume and tree age for alder in Ecuador was then developed. Managing alder on 1 hectare of farmland and 1 hectare of pasture land on a 20-year rotation with one thinning at 10 years would yield a total tree volume of 372.8 cu m, which would provide wood for fuel, construction, and other wood products. Actual fuelwood consumption for Saraguro, Loja, Ecuador was calculated to be 3.5 m3/year per household. © 1990 Kluwer Academic Publishers.
