Key message: Three options are proposed to improve the accuracy of national forest biomass estimates and decrease the uncertainty related to tree model selection depending on available data and national contexts. Introduction: Different tree volume and biomass equations result in different estimates. At national scale, differences of estimates can be important while they constitute the basis to guide policies and measures, particularly in the context of climate change mitigation. Method: Few countries have developed national tree volume and biomass equation databases and have explored its potential to decrease uncertainty of volume and biomasttags estimates. With the launch of the GlobAllomeTree webplatform, most countries in the world could have access to country-specific databases. The aim of this article is to recommend approaches for assessing tree and forest volume and biomass at national level with the lowest uncertainty. The article highlights the crucial need to link allometric equation development with national forest inventory planning efforts. Results: Models must represent the tree population considered. Data availability; technical, financial, and human capacities; and biophysical context, among other factors, will influence the calculation process. Conclusion: Three options are proposed to improve accuracy of national forest assessment depending on identified contexts. Further improvements could be obtained through improved forest stratification and additional non-destructive field campaigns. © 2015, The Author(s).

We present an analysis of the implementation of the main conservation policies in the Reventazón Model Forest in Costa Rica, and its contribution to the sustainability of environmental services. The existing environmental legislation has helped to curtail environmental degradation and loss of forest cover. The Reventazón Model Forest is an initiative created as a means of implementing Costa Rica's commitment to the application of the ecosystem approach, and has served as a framework for putting into practice sustainable development policies with broad participation by communities in Cartago Province. The Payment for Environmental Services (PES) program has played a role in forest conservation and reforestation in 9% of the Model Forest. The challenge now is to increase the impact of this program in the Reventazón Model Forest, above all in the biological corridors, and we analyze some of the causes that could be limiting the PES program.

The Costa Rican Program of Payments for Environmental Services (PPES) is a global pioneering financing policy mechanism for the promotion of forest protection and expansion. This program currently transfers a significant amount of money to indigenous territories; however, its performance has not been comprehensively evaluated. In this study we assessed for the first time in a comprehensive manner the performance of this national program in an indigenous territory. We created and validated, with the aid of a panel of experts, an evaluation instrument that contains social, economic, and environmental criteria and indicators. After applying the instrument in the Talamanca-Cabecar indigenous territory (TCIT), the PPES obtained 48.7 percent, accomplishing significant results in aspects framed within the goals of sustainable development. We found that the TCIT allocates most of the payment money into capacity building, which has resulted in substantive improvements in their negotiation, management, and leadership skills; this in turn helps to attract investments from other public and private entities, protecting and promoting its natural capital. As similar programs are adopted in multiple countries based on the Costa Rican example, this study provides an important methodological contribution to enlighten future environmental and socioeconomic financing policies aiming to support indigenous territories. © 2014 Elsevier B.V.
