Based on a set of reference indicators, a tool was designed for the evaluation “ex post” of sustainability of units of managed natural forests in Costa Rica. This set was developed using a hierarchical structure of principles, criteria and indicators of sustainability. The resulting reference list consists of 5 principles, 12 criteria and 30 indicators, classified as essential by a group of experts in forest management in Costa Rica. The set of indicators allows studying the dimensions and attributes that delimit the sustainability of the ecosystems. The selection procedure and the likely contribution of this set to forest management addresses, firstly, the economic, social, ecosystemic and institutional conditions of Costa Rica. However, the set of indicators is useful for other regions of the world, previous adaptation of the threshold values to the local conditions of the ecosystem. Additionally, the ecosystemic dimension (productivity, stability, adaptability) is ratified as a condition of first order for the sustainability, but the experts reinforce the idea that the institutional dimension (equity and governance) is a challenge for the evaluation of sustainability.

基于一组参考指标，设计了一种用于“事后评估”的工具。“哥斯达黎加受管理的天然林单位的可持续性”。该集合是使用原则，标准和可持续性指标的分层结构开发的。最终的参考清单包括5条原则，12条标准和30项指标，被哥斯达黎加的森林管理专家组分类为必不可少的。这套指标允许研究限制生态系统可持续性的维度和属性。选择程序及其对森林管理的可能贡献首先涉及哥斯达黎加的经济，社会，生态和体制条件。但是，这组指标对世界其他地区很有用，因为之前已根据生态系统的当地条件调整了阈值。另外，
