Foliar herbivory and leaf traits of five native tree species in a young plantation of Central Panama

Background

Timber plantations often provide economic incentives for land owners to restore abandoned pastures or agricultural land to forest, yet the threat of insect herbivory can diminish these new plantations and compromise the efforts. This study seeks to understand the extent of these threats on tree plantations in Panama.

A Survey of Small-Scale Farmers Using Trees in Pastures in Herrera Province, Panama

background

The Herrera Province on the Azuero Peninsula of Panamá has experienced significant deforestation for the purpose of cattle ranching.

research goal & methods

The goal of the study was to determine more information about the use of trees in smallholder cow pastures. Herreran pasture owners were interviewed about the different uses for trees in their pastures as well as the variety of tree species.

Pure and Mixed Forest Plantations with Native Species of the Dry Tropics of Costa Rica: A Comparison of Growth and Productivity

background

This research monitored the growth and survival of 13 natives species in pure and mixed-species plantations, and compared the results to measurements of T. grandis, an exotic species commonly planted in the area.

The Agua Salud Project, Central Panama

Background

The Agua Salud Project is located in the watershed that includes and surrounds the Panama Canal, an engineering feat that largely relies on natural hydrological systems. Much of this watershed has been deforested, thus an official policy has been put into place to reforest and regain ecosystem services. This project seeks to utilize the globalize role of the canal to bring attention to the ecosystem services of the region.

Restoration of dry tropical forests in Central America: A review of pattern and process

Background

Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

An Evaluation of Farmers' Experiences Planting Native Trees in Rural Panama: Implications for Reforestation with Native Species in Agricultural Landscapes

background

The Panamanian government has created reforestation incentive programs to encourage farmers to plant trees in order to restore ecosystem services to degraded lands. However, many farmers and landowners choose not to participate in these programs. Additionally, many such incentive programs result in large plantations of non-native species. In 2001, the Smithsonian Tropical Research Institute created a native species reforestation project known as PRORENA (Proyecto de Reforestación con Especias Nativas) to study strategies for successful native species reforestation in a social, economic, and scientific context.
