Landscape Rehabilitation of Degraded Tropical Forest Ecosystems: Case Study of the CIFOR/Japan Project in Indonesia and Peru

background

The CIFOR/Japan project on tropical forest restoration involves three principal components: 1) evaluation of logging impacts on forest systems, 2) development of methods for the restoration of logged and degraded forests, and 3) development of silvicultural practices for degraded forests.

Fire in the Seasonal Semideciduous Forest: Impact and Regeneration at Forest Edges

background

This study looks at a fragment of semi-deciduous forest in Brazil to determine the effects of fire on vegetation at varying distances from the fragment’s edge, as well as the recovery of forest structure and species diversity after fire.

Seed development, yield and quality of two palm species growing in different tropical forest types in SE Brazil: implications for ecological restoration

Background

Natural forest remnants have been set as seed production fields to supply seeds of native tree species for tropical forest restoration, but the effect of different forest types on seed production has not been accessed to date for palm species. This study reports on seed development, yield, and quality of two palm species in different tropical forest types in SE Brazil.

Effects of Different Light Levels on the Initial Growth and Photosynthesis of Croton urucurana Baill. in Southeastern Brazil

background

This study measures the effect of different levels of shading on growth, chlorophyll concentration, and photosynthetic rate of Croton urucurana, a pioneer species potentially important in reforestation efforts in riparian forests of Brazil.

The Apparent Paradox of Reestablishing Species Richness on Degraded Lands with Tree Monocultures

background

This article discusses the use of tropical tree plantations as an approach to rehabilitation of degraded landscapes. For extremely degraded sites, the use of plantations may provide the proper shade, microclimate and protection for other species to colonize the understory. Research on the use of plantations in restoration is discussed, with examples primarily from Puerto Rico.

Growth and effects of thinning of mixed and pure plantations with native trees in humid tropical Costa Rica

Background

As reforestation with native tree species gains in popularity, more information about proper management is needed. This study examines the growth and responses to thinning of ten native species in mixed and pure-species plantations in the Caribbean Lowlands of Costa Rica.

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.

Temporary Storage of Jussara Palm Seeds: Effects of Time, Temperature and Pulp on Germination and Vigor

background

The seeds of the jussara palm (Euterpe edulis) are recalcitrant and immediate sowing is not always possible after harvest; hence, research that examines the ability of the seeds to be stored and the effect of this storage on germination proves important.

Performance of forest plantations in small and medium-sized farms in the Atlantic lowlands of Costa Rica

Background

While exotic trees are typically used in plantations throughout the tropics, there has been recognition that certain native species are also suitable. This study aims to compare the viability of both native and exotic tree species for plantation use.
