9508683 Holl This project constitutes the initial phase of a long-term study of tropical moist forest recovery from human-induced disturbance. The goals of this study are to better understand factors limiting the recovery of tropical moist forest ecosystems from human disturbance and to develop practical methods for accelerating such recovery. Surveys of vegetation, soil, microclimatic variables, and seed rain of primary forest, secondary forest, and agricultural land will provide baseline data on differences between these habitats from which to measure recovery of disturbed habitats. These data will also serve to generate hypotheses about factors potentially limiting recovery that will be tested following the planning period. %%% Strategies for accelerating recovery will be tested in small-scale manipulative plots. Initial experiments will focus on accelerating recovery by augmenting seed dispersal and ameliorating stressful microclimatic conditions. Mapping of land-use types in this area will provide a database for development of further studies of forest recovery. Jointly, these activities will serve as the basis for developing a large-scale research project of tropical moist forest restoration. ***

这个项目是热带潮湿森林从人为干扰中恢复的长期研究的初始阶段。本研究的目的是更好地了解限制热带潮湿森林生态系统从人为干扰中恢复的因素，并制定加速这种恢复的实用方法。对原生林、次生林和农田的植被、土壤、小气候变量和种子雨的调查将提供这些栖息地之间差异的基线数据，以此来衡量受干扰栖息地的恢复情况。这些数据还将有助于产生关于可能限制采收率的因素的假设，这些因素将在规划期后进行测试。加速恢复的策略将在小规模操作地块中进行测试。最初的实验将集中在通过增加种子传播和改善紧张的小气候条件来加速恢复。绘制这一地区土地利用类型的地图将为进一步研究森林恢复提供一个数据库。这些活动将共同成为制定热带潮湿森林恢复大型研究项目的基础。＊＊＊
