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

Testing Applied Nucleation as a Strategy to Facilitate Tropical Forest RecoveryBackgroundThis study considers applied nucleation, or the intensive planting of small patches of a mixture of successional species, as a degraded tropical forest restoration strategy. This approach catalyzes the natural regeneration of the surrounding matrix and larger landscape and could provide a less expensive alternative to the more common, and expensive, plantation-style approach. This study claims to be the first to directly compare tree recruitment beneath these two restoration approaches. Open access copy available |
Seed rain under tree islands planted to restore degraded lands in a tropical agricultural landscapeBackgroundPlanting native tree seedlings is the predominant restoration strategy for accelerating forest succession on degraded lands. However, planting tree “islands” is less costly and labor intensive than establishing larger plantations and simulates the nucleation process of succession. Tree islands can attract seed dispersers to gradually spread restoration patterns from the islands. Restoration design can be informed by assessing the effect of potential planting arrangements on seed dispersal by birds and bats and determining the influence of surrounding forest cover.

Woody Plant Diversity and Structure of Shade-Grown-Coffee Plantations in Northern Chiapas, MexicobackgroundThis article presents research on coffee stand structure and diversity, with data collected from 61 coffee plots in Chiapas, Mexico. Research Goals & MethodsThe 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.

Coffee yields and soil nutrients under the shades of Inga sp. vs. multiple species in Chiapas, MexicoBackgroundThe type of canopy structure that provides shade to shade-grown coffee may make a difference in production. While Mexican coffee producers have often sought to replace a natural diverse canopy with Inga latibracteata alone, the benefits of either method for yield and for ease of management have not been adequately studied.
