Tropical Secondary Forests (SFs) are vulnerable forest systems growing in areas that have been subject to unsustainable human activities leading to deforestation. SFs account for swathes of tropical forest landscapes that have lost their capacity to provide a high level of goods and services. They are also located in highly dynamic and human-pressured landscapes and are vulnerable to natural and human-induced catastrophic events, such as hurricanes or fires. Without appropriate silvicultural management to increase their economic value and restore their ecological functions, they often become degraded and are sometimes cleared for more short-term economically productive activities. Given the increasing demand for tropical timber in recent decades that will continue in the near future, we suggest that active restoration geared towards wood production is an opportunity for SF conservation. Promoting sustainable wood production -i.e. associated with other environmental services- in these disturbed forest ecosystems is also a way to reduce logging pressure on the remaining intact primary tropical forests, indeed, this may be the most important reason to enhance active restoration aimed at wood production in tropical SFs worldwide. Future research in forest ecology and management should produce experimental evidence of enhanced production of wood and ecosystem services in SFs through appropriate silvicultural experimentations.

热带次生森林（SFs）是脆弱的森林系统，生长在遭受不可持续人类活动导致森林砍伐的地区。SF造成大量热带森林景观丧失了提供高水平商品和服务的能力。它们还位于高度动态和人为压力的景观中，容易遭受自然和人为灾难性事件的影响，例如飓风或火灾。如果没有适当的营林管理来增加其经济价值并恢复其生态功能，它们往往会退化，有时会被清除以从事更短期的经济生产活动。鉴于最近几十年来对热带木材的需求不断增长，并且这种需求在不久的将来还将持续，我们建议针对木材生产的积极修复是SF养护的机会。在这些受干扰的森林生态系统中促进可持续的木材生产（即与其他环境服务相关联）也是减轻剩余的完整原始热带森林伐木压力的一种方法，的确，这可能是加强针对木材生产的积极恢复的最重要原因在全球热带SF中。未来有关森林生态和管理的研究应通过适当的造林试验，为加强小规模生产中木材和生态系统服务的生产提供实验证据。与其他环境服务相关联-在这些受干扰的森林生态系统中，这也是减轻剩余的完整原始热带森林上伐木压力的一种方式，的确，这可能是加强针对全球热带SF木材生产的积极恢复的最重要原因。未来森林生态学和管理研究应通过适当的造林试验，为加强小规模森林木材和生态系统服务的生产提供实验证据。与其他环境服务相关联-在这些受干扰的森林生态系统中，这也是减轻剩余的完整原始热带森林上伐木压力的一种方式，的确，这可能是加强针对全球热带SF木材生产的积极恢复的最重要原因。未来有关森林生态和管理的研究应通过适当的造林试验，为加强小规模生产中木材和生态系统服务的生产提供实验证据。
