Species-Specific Tree Water Use Characteristics in Reforestation Stands in the Philippines

Background

The need for reforestation is becoming increasingly evident in countries like the Philippines where deforestation has lead to a scarcity of wood and other forest commodities. One concern with reforestation is the reduction in streamflow and groundwater recharge as trees move water from the ground into the atmosphere.

Research Goals & Methods

This study seeks to investigate the sap flux responses and tree water use in two 12-year-old multi-species stands.

The Reforestation Value Chain for the Philippines

background

This paper describes the reasons for the failure of reforestation projects in the Philippines and the potential actions to improve success. When reforestation is focused narrowly on tree plantings, they can last for a few years (mostly 3) but then are easily cut by farmers who want to resume farming, by people in need of wood, or by people feeling that the reforestation was unjust. Most reforestation projects do not have plans beyond tree establishment.

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.

Community Reforestation in the Philippines: An Evaluation of Community Contracts

background

Since the 1950s, the Phillipines has lost over 15 million hectares of tropical forest. While there has been continued efforts to halt these trends and reforest the loss areas, there has been many barriers; thus the country recently turned to private and community-based efforts. This study is a review of two reforestation projects in the Philippines that were contracted through private entities rather than government agencies.

Growth, carbon sequestration, and management of native tree plantations in humid regions of Costa Rica

Background

The Costa Rican government has provided incentives for reforestation programs since 1986 and initiated a Payment for Environmental Services program in 1996. These incentives yielded native species reforestation programs throughout the country. This study examines growth, carbon sequestration, and management of seven native tree species (Vochysia guatemalensis, Vochysia ferruginea, Hyeronima alchorneoides, Calophyllum brasiliense, Terminalia amazonia, Virola koschnyi, and Dipteryx panamensis) in single-species plantations managed by small landowners.

Regeneration of Native Plant Species in Restored Forests on Degraded Lands in Singapore

background

This article presents the natural regeneration of woody species in the understory of 1 year-old and 4-year old plantation in Singapore.

Research Goals & Methods

Although the the site was cleared, except for remnant trees,before planting, the rootmatt of the fern Dicranopteris was left in the plots. One plot within each site had the rootmat manually removed. Regeneration of species greater than 10 cm in length were counted and identified.
