ERECON, Ministry of Environment Cambodia, UNU: Kampong Cham province, Mondol Kiri province, and Battam Bang province, Cambodia

Background

Deforestation has been a signficant issue in Cambodia since the 1970s due to agricultural expansion and unstable political eras. This has caused severe flooding or drought downstream, environmental degradation and loss of biodiversity. Relatively recently, there has been an increasingly call to promote restoration and conservation of environment and sustainable use and management of natural resources.

Reforestation of mangroves after severe impacts of herbicides during the the Viet Nam war: the case of Can Gio

Background

Due to years of armed conflict and the extensive use of toxic chemicals in Vietnam in the 1960s, tens of thousands of hectares of mangrove forests were destroyed. In 1978, the People's Committee of Ho Chi Minhi City recognized this lost and began investing in reforestation efforts.

Forest in the Air Project

Background

As a joint venture by Conservation International and Daikin, the Forest in the Air Project works in Gunung Gede Pangrango National Park in Indonesia. The forest is not only home to a variety of flora and fauna but also provides critical ecosystem services. Like other forests in Indonesia, the park is under threat from agriculture and other human activities, such as illegal logging.

Fallow to Forest: Applying Indigenous and Scientific Knowledge of Swidden Cultivation to Tropical Forest Restoration

Background

This study analyzed vegetation at two sites of shifting cultivation by Lawa and Karen indigenous people in the Mae Chaem watershed in 1-year, 3-year and 6-year fallow fields, with an area of natural forest as a control comparison.

Biodiversity–Productivity Relationships in Small-Scale Mixed-Species Plantations Using Native Species in Leyte Province, Philippines

background

The growth of tropical reforestation in recent decades has given rise to a debate between the relative productivity, biodiversity, and general merits of mixed-species vs. single-species plantations. To further investigate the relationship between tree species diversity, productivity, and abiotic factors such as climate and soil, this study investigated the growth of mixed-species plantations in Leyte province in the Philippines. These smallholder plantations were planted in 1992 to meet social, economic, and environmental needs through the Rainforestation Farming system.

Early Effects of Four Fast-Growing Tree Species and Their Planting Density on Ground Vegetation in Imperata grasslands

background

This study aims to test the success of fast-growing exotics tree species and alternative planting densities on the development of ground vegetation. The study was conducted in Riam Kiwa, South Kalimantan, Indonesia in Imperata grasslands. The four fast-growing exotic tree species used in the study were Acacia mangium, Acacia crassicarpa, Gmelina arborea, and Paraserianthes falcataria.

Degraded Lands Worth Protecting: the Biological Importance of Southeast Asia's Repeatedly Logged Forests.

Background

The study examines the impacts of second logging cycles on biodiversity by comparing species richness, species composition and population-level responses of birds and dung beetle species across unlogged forest, first rotation forest, and second rotation forest in Sabah, Malaysia.

Research Goals & Methods

The authors sample 18 sites, 6 for each forest type, over a two year period. They use point count and mist net censuses for bird species and pitfall traps to count dung beetles.

Nurse Plant Theory and its Application in Ecological Restoration in Lower Subtropics of China

background

This study examines the mechanisms of the nurse tree effect and ecological factors that influence tree nursing and its relationship to ecological restoration.

Research Goals & Methods

The authors list different pairs of nurse and target tree species, including the broad description of such pairs and research findings of case studies in several locations in lower subtropical China. They also examine the positive and negative feedback loops between nurse trees and target species and explain why the nursing effect occurs.

Monitoring Forest Degradation in Tropical Regions by Remote Sensing: Some Methodological Issues

Background

This review examines different remote sensing techniques to monitor vegetation cover at a regional scale. The objective was to discuss implications related to monitoring of open forest degradation.

Research Goals & Methods

Techniques include methods to track both spatial and temporal changes in structure and function associated with land use change.
