In 1990 four Peace Corps Volunteers in Costa Rica completed their service and started a private reforestation project. The goal was to see if a small tree plantation could be profitable compared with traditional land uses. This article discusses the economics of the first 15 years of the project, using actual cash flows, and makes projections for financial outcomes. We documented the yearly expenses and revenues (cash flows) for operating a small tropical woodlot, costs and/or revenues from the specific woodlot management operations, and profit projections over the 25-year life of the project. We used realized growth rates, milling costs, and wood sale prices to show that small-scale reforestation with mixtures of native species can be financially profitable, both for an investor and a farmer/landowner.

哥斯达黎加本地物种小规模热带重新造林的财务分析

1990年，哥斯达黎加的四名和平队志愿者完成了他们的服务并开始了私人重新造林项目。目标是看看与传统的土地利用相比，小型种植园是否可以盈利。本文使用实际现金流量讨论了该项目前 15 年的经济情况，并对财务成果进行了预测。我们记录了经营小型热带林地的年度费用和收入（现金流）、特定林地管理业务的成本和/或收入，以及项目 25 年生命周期的利润预测。我们使用已实现的增长率、铣削成本和木材销售价格来表明，对于投资者和农民/土地所有者来说，混合本地物种的小规模重新造林可以带来经济利润。
