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.

Institutional Issues and Political Challenges in Scaling Up Agroforestry: The Case of Landcare in the Philippines

background

This paper presents the results of case studies of four municipalities in the Philippines participating in the Landcare agroforestry program which benefited from differing levels of institutional, technical, and government support. The paper assesses how effectively the Landcare program was able to scale up based on differing levels of support.

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.

Restoration of Degraded Tropical Forest Landscapes

Background

The rapid loss and degradation of tropical forests has been one of the defining features of the 20th century, with an estimated 350 million ha deforested and another 500 million ha (primary and secondary forest) in degraded status. There have been three major responses to this process: expanding protected areas; improving agricultural productivity on cultivated and abandoned lands; and plantation-style reforestation using a very limited number of species. These methods have proven unsuccessful in slowing the rate of deforestation or providing adequately for livelihoods.

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.

What Role Should Government Regulation Play in Ecological Restoration? Ongoing Debate in São Paulo State, Brazil

background

This article addresses the degree of detail that should be present in legislation dealing with reforestation and restoration, and if there is a relationship between technical content/scope of regulation and success of projects. The relationship between law and reforestation is also discussed. In São Paulo state, legislation establishes precise reforestation requirements, such as the use of a minimum of 80 species of native trees and the presence of specific proportions of functional groups. This is the only existing legislation known by the authors with this degree of technical detail.

Growth Increments of Indigenous Species Planted in Secondary Forest Area

Background

Appropriate species selection for reforestation of degraded lands in the tropics makes a great difference in survival rates and success in establishing secondary forest. Indigenous species used in reforestation are not always able to survive in their native landscapes based on the degree of site degradation. This paper reports on growth increments of five tree species indigenous to Malaysia five years after planting.

Rehabilitation of Tropical Rainforests Based on Indigenous Species for Degraded Areas in Sarawak, Malaysia

background

This study describes the success of native species planted in areas of abandoned shifting cultivation in Sarawak, Malaysia.

Research Goals & Methods

Site contitions in which species were planted included:  open conditions, including severely eroded and compacted areas and man-made mounds, and shady conditions. Growth and survival was recorded for 60-72 months, depending on the site

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.
