Tropical Montane Forest Restoration in Costa Rica: Overcoming Bariers to Dispersal and Establishment

Background

The article addressed different types of environmental and ecological factors limiting forest regeneration on a tropical montane abandoned pasture in Costa Rica, and the subsequent forest restoration strategies that could be feasible.  The authors sought to answer the following questions: 1) What factors limit tropical forest recovery in abandoned pasture? and (2) How can we use this information to design strategies to facilitate ecosystem recovery?

Woody Plant Diversity and Structure of Shade-Grown-Coffee Plantations in Northern Chiapas, Mexico

background

This article presents research on coffee stand structure and diversity, with data collected from 61 coffee plots in Chiapas, Mexico.

Research Goals & Methods

The following variables were measured: coffee density, slope, plot aspect, the number of individuals of each shade species (divided into 9 diametric classes), number of strata, species use, and presence of woody plant species.

Local and Regional Environmental Variation Influences the Growth of Tropical Trees in Selection Trials in the Republic of Panama

background

This study evaluates the effect of varying site conditions on the basal area of 21 neotropical and 2 exotic tree species at three different sites in Panama. 

Research Goals & Methods

Seedlings were planted in 2003 in randomized blocks and measured for basal diameter, height, live crown length, and crown diameter each year from 2004 to 2006.

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.

Initial Performance and Reforestation Potential of 24 Tropical Tree Species Planted Across a Precipitation Gradient in the Republic of Panama

background

The authors of this study  planted trees from 22 native species and two exotic species to use in selection trials testing the growth and survivability of trees in plantations in three different sites.

Research Goals & Methods

The sites were chosen for their precipitation gradient from Soberania National Park (2226mm mean annual rainfall), Los Santos (1946mm rainfall), and Rio Hato (1107mm rainfall). Survival, basal diameter, height, crown diameter and wood volume index (VI) were calculated after two years of growth.

Biomass Distribution Among Tropical Tree Species Grown Under Differing Regional Climates

background

This study presents results from species selection trials in Panama as part of the PRORENA project, which examined the most effective species and methods for Panamanian government-supported reforestation projects.

research goal & methods

In 2003, 16 native and 2 exotic species were planted in single-species plots with a 3m x 3m spacing of trees at two different sites (one seasonally wet, one more dry). All plots were thinned to 50% of their original density at two years after plantation establishment, and the thinned trees were measured for biomass and biomass partitioning.
