Rehabilitation of Degraded Forest with Shorea leprosula and S. selanica Cuttings

background

This article describes limits to dipterocarp-based reforestation due to irregular flowering pattern, short seed storage period, and uncertain planting techniques in Southeast Asia. In West Java, Indonesia, the authors test the effectiveness of vegetative propagation for two species of fast-growing dipterocarps: Shorea leprosula and Shorea selanica.

Reasons for reforestation success and failure with three mangrove species in Colombia

Background

This study examines the mortality and growth rates of the propagules, seedlings and saplings of three native mangrove species (A. germinans, L. racemosa, and R. mangle) in order to determine the ecological factors that influence tree growth and survival in deforested mangroves with restored hydrologic conditions on the Caribbean coast of Colombia.

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.

Growing agroforestry trees: Farmers’ experiences with individual and group nurseries in Claveria, Philippines

Background

In the 1990s, a Landcare movement formed in Claveria, South Philippines, establishing community nurseries for fruit and timber trees based on a growing interest in promoting agroforestry and soil conservation. Ten years after the formation of these nurseries, the authors interviewed growers about the successes and limitations of that effort.

The Role of Animal Seed Dispersal in Accelerating Native Forest Regeneration on Degraded Tropical Lands

background

This article reviews the role of seed-dispersal in forest regeneration. In natural forest, species with animal-dispersed species tend to predominated in both early and mid-stages of succession, while wind-dispersed species tend to be vines and canopy species. The implications of wind versus animal seed dispersal are briefly summarized.

Studies on the Seed Biology of 100 Native Species of Trees in a Seasonal Moist Tropical Forest, Panama, Central America

Background

Since 1998, the Panama Canal Watershed has experienced a decline in forest cover. The watershed ensures a functioning canal, thus there has been a significant investment in resources to reforest and restore the region. While these projects have focused primarily on native species, there has been issues with seed-handling.

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.

Sustaining Tropical Forest Resources: Reforestation of Degraded Lands

background

This government report provides background material on tropical reforestation and discusses techniques to reforest degraded tropical lands. It considers species planting issues such as: native v. exotic species, monoculture v. polyculture, single purpose v. multipurpose trees, and genetic improvement and plant breeding.
