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.

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.

Methods of Facilitating Reforestation of Tropical Degraded Land with the Native Timber Tree, Terminalia amazonia

background

In tropical dry regions, like Costa Rica, it is critical to reforest degraded farms in order to reduce erosion and increase soil fertility. This paper explores the results of an 8-year long experiment in Southern Costa Rica that sought to identify ways to reforest such land economically.

Growth of native forest species planted on abandoned pasture land in Costa Rica

Background

Reforestation programs in Costa Rica have largely utilized only four tree species. This study tests growth rates and form of eleven additional tree species native to the humid tropics, including five N-fixing species and six non-N-fixing species.

Direct Seeding of Late-Successional Trees to Restore Tropical Montane Forest

background

This study measures seed germination, seedling establishment, survival, growth and foliar nutrient content of five late-successional tree species which were directly seeded into three different habitats representing different stages of succession in tropical montane Costa Rica.The study also compares the costs of direct seeding with locally collected seeds with planting nursery-raised seedlings.

Planting Seedlings in Tree Islands Versus Plantations as a Large-Scale Tropical Forest Restoration Strategy

background

This research compares the growth and mortality of 4 tree species (2 native to Costa Rica and 2 native to northwestern South America) in the reforestation of abandoned agricultural land in Costa Rica.

Performance of an Improved Fallow System in the Peruvian Amazon—Modelling Approach

background

This research compares the ecological and economic potential of an improved leguminous tree fallow (using Inga edulis) to the traditional grass fallow (dominated by Imperata brasiliensis) in central Peru.

Biomass Growth and Farmer Knowledge of Inga edulis in Peruvian Amazon

background

This study develops an equation for diameter-based biomass estimation of Inga edulis. The tree is widely grown in the Peruvian Amazon as a naturally occurring early-successional tree and in small farms and gardens for fruit and fuelwood.

Participatory Domestication of Agroforestry Trees: An Example from the Peruvian Amazon

background

This paper describes a program through the International Centre for Research in Agroforestry (ICRAF) to work with farming communities to domesticate native tree species for use in agroforestry and the conservation of tree diversity in their forests.

Patch Size Effects on Avian Foraging Behaviour: Implications for Tropical Forest Restoration Design

background

This study looks at bird behavior in restoration sites in southern Costa Rica. While multiple studies examine the presence of birds in restored forest, few studies examine behavior in these sites.
