Towards an Ecology-Based Strategy for the Reforestation of Imperata cylindrica Grasslands in East Kalimantan

background

This chapter assesses an ecology-based strategy to accelerate the reforestation of grassland towards a dipterocarp-dominated plantation with natural regeneration occuring.

Growth of dipterocarp seedlings in artificial gaps: An experiment in a logged-over rainforest in South Kalimantan, Indonesia

Background

Regeneration of dipterocarps following logging has become a crucial issue in tropical forest management. Secondary forest frequently and rapidly replaces dipterocarps in large logged-over patches. If unmanaged, these secondary forest patches are often composed of unmerchantable early-succession species. It has been hypothesized that dipterocarps grow most successfully in small gaps.

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

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 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.

Enrichment Planting of Dipterocarps in Logged-Over Secondary Forests: Effect of Width, Direction and Maintenance Method of Planting Line on Selected Shorea Species

background

In this study, three different planting design experiements were conducted using three Dipterocarp tree species planted in a heavily logged area of South Kalimantan. The area was logged in 1979 and used for shifting cultivation until 1988.

Performance of 45 Native Tree Species on Degraded Lands in Singapore

background

This paper evaluates research on the reforestation potential of 45 native tree species in Singapore, with a specific focus on identifying species that can quickly form a closed canopy.

Research Goals & Methods

Annual growth rate and survival was calculated for saplings (total 1640) planted between 1999 and 2004 on seven different sites, 3 dry, 2 average, 2 wet.

Survival and Growth of Under-Planted Trees: A Meta-Analysis Across four Biomes

background

This article is a meta-analysis synthesizing the results of survival and growth of under-planted trees in forests in tropical, temperate coastal, boreal, and temperate deciduous forests. Additionally, the survival and growth of these underplanted trees are evaluated according to the silvicultural treatment affecting density of the overstory: uncut, dense shelterwood, intermediate density shelterwood, light density shelterwood, clear cut.
