龙脑香混交林是世界上最高产材的森林之一。森林区域以占主导地位的树冠树科Dipterocarpaceae命名，其中两个主要属（Dipterocarpus，Shorea）通常代表不成比例的断面积。与拉丁美洲和非洲相比，非洲的每公顷可销售木材的现存量要高得多，但它们也是第一个被过度开发和退化的地区（1970年至今）。大多数现在仅限于高地地区，如果要成功管理，需要各种恢复技术。本研究介绍了斯里兰卡西南部的一个财政上可行的管理制度的造林。我们的研究表明，管理木材和非木材森林产品（NTFP）的富集种植相结合的林地可以与最具竞争力的相邻土地利用-茶园。通过对非木材森林产品和木材的管理，森林管理人员有了新的机会来解决高等级和土地用途转换的老问题。此外，与其他竞争性土地使用价值相比，为包括水质和产量在内的生态系统服务付费以及碳信用额将使森林价值翻一番。
Mixed dipterocarp forests (MDF) were one of the most timber productive forests in the world. The forest region is named after the dominant canopy tree family Dipterocarpaceae within which two major genera (Dipterocarpus, Shorea) usually represent a disproportionate amount of the basal area. Compared with Latin America and Africa, MDF have much higher standing volumes of merchantable timber per hectare, but they were also the first to be over exploited and degraded (1970-ongoing). Most are now restricted to upland regions and require various restorative techniques if they are to be successfully managed. This study describes the silviculture of a financially viable management regime for southwest Sri Lanka. Our studies demonstrate that managing MDF for a combination of timber and enrichment plantings of nontimber forest products (NTFP) can be comparable to the most competitive adjacent land use – tea plantations. By managing for NTFP and timber, forest managers have new opportunities to solve the old problems of high-grading and land-use conversion. In addition, payments for ecosystems services that include water quality and yield, and credits for carbon would double forest value when compared with other competing land use values.
