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.

Ecological Considerations for Using Dipterocarps for Restoration of Lowland Rainforest in Southeast Asia

background

In this article, the authors present ecological factors that should be considered when engaging in dipterocarp forest restoration in Southeast Asia. Because many dipterocarps are insect-pollinated, have poor seed dispersal, have low density of reproductive adults, and have recalcitrant seeds, planting of nursery-reared tree seedlings could increase the ability of dipterocarp forests to regenerate.

Tropical Montane Forest Restoration in Costa Rica: Overcoming Barriers to Dispersal and Establishment

background

Due to the rapid pace of tropical deforestation, it is essential to design restoration experiments that both further basic knowledge of tropical ecology and inform management strategies to facilitate recovery of these ecosystems. This study synthesizes the results of recent research on tropical montane forest recovery in abandoned pasture in Costa Rica to address limitations on tropical forest recovery in abandoned pasture and designing strategies to facilitate ecosystem recovery.

Factors Limiting Tropical Rain Forest Regeneration in Abandoned Pasture: Seed Rain, Seed Germination, Microclimate, and Soil

background

This research evaluates the ability of seeds to be dispersed into and germinate in areas of abandoned pasture.

Research Goals & Methods

Seed rain, germination of tree seedlings, percent herbaceous and woody cover, soil moisture, phosphorous, air temperature, and other microclimate conditions were tested in plots located 250m and 25m from the forest edge as well as within the primary forest.

Ulu Masen REDD+ initiative, Aceh, Indonesia

Background

The area of the Ulu Masen Conservation Area has been degraded due to an illegal logging boom after the tsunami as well as increasing agricultural expansion. The Ulu Masen REDD+ initiative was developed by the Government of Aceh (GoA) to address these issues.

Canopy development in tropical tree plantations: a comparison of species mixtures and monocultures

Background

The establishment of plantation monocultures has dominated much of the intensive forest management practiced in the humid tropics of the Americas, with most forestry research and practice concentrating on a small number of non-indigenous species. Growing interest exists in modifying these practices both by creating mixed-species plantations and by making greater use of native tree species.

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.
