Secondary cloud forests in Mexico (SCF)
Sustainable management potential of secondary cloud forests in Mexico
Secondary cloud forests are gaining increased importance. Given the high ecological significance of cloud forests, specifically in the tropics, their re-establishment and the use of secondary cloud forests needs an improved scientific basis. This project uses the case of Mexico to asses challenges and benefits of their management, to study their ecology and based on this provide recommendations for their sustainable management.
Background and Objective
The sustainable management of Secondary Cloud Forests (SCF) poses many challenges, including the lack of legal definitions for secondary forests and the absence of effective policy instruments and economic incentives for landowners. There are also natural limitations of the system, due to small commercial timber volume for species in the established market economic profitability is reduced and this condition can deter management for the provision of timber. However, it remains an open question what is the economic value of the management of SCF for the production of timber. The lack of information for the management of SCF species adds to the constraints to support the development of management schemes. Sustainable management of SCF requires an understanding of forest dynamics; the influence of environmental factors on the growth rates of native tree species and tree regeneration dynamics, a critical establishment phase, are poorly known. While the natural recovery can occur, it can be frequently limited and in such cases restoration strategies are required.
The main goal of this project is to advance our understanding of the dynamics and potential for sustainable management of SCF by: (1) assessing the main challenges and benefits for sustainable management in Mexico, (2) estimating the potential productivity of timber and its economic value, (3) advancing the understanding of natural tree recruitment, and (4) evaluating the success of restoration plantings.
