8th Ro Suhardi Faculty of Forestry, Gadjah Mada University Indonesia Abstract Natural forest of dipterocarps in Indonesia is decreasing at an estimated rate of about 1.6 to 2.3 million ha per year and Indonesia need more than 50 million cubic meter of dipterocarps especially to supply its industries, house construction and maintain its timber exports. Areas planted oil palm have been increasing every year and more investors are willing to invest in oil palm plantation rather than … [Read more...]

Supriyanto and U.S. Irawan SEAMEO BIOTROP, Bogor, Indonesia Abstract Frequent forest fires, shifting cultivation, illegal logging, and over-extraction of timber resources, have destroyed most of Indonesia’s natural forests. It is important to replant the degraded forest using high-quality seedlings. Enrichment planting is the cheapest way to plant the degraded areas, without disturbing the soil structure, and biodiversity composition. The recommended species are generally from … [Read more...]

Introduction Many species of dipterocarps are emergence trees and are classified as shade tolerance species. Their seeds normally germinate under the canopy shade and their seedlings could stay ‘dormant’ in the seedling bank while waiting for a gap to be created. Low light condition (1-5% sunlight), with high proportions of long-wavelength red and infrared light, is insufficient to sustain the seedling growth and development. Thus, the availability of gaps is critical for the … [Read more...]

The irregular management practices and regeneration problems resulted in the degradation of natural forest population of this species. In order to conserve the natural forest of D. retusus and to ensure the sustainable supply of raw … [Read more...]

Abstract Wild mushrooms are annually harvested for food from dry and wet dipterocarp forests of northern Thailand. Most of the species gathered fruit in association with host trees and form symbiotic associations know as ectomycorrhizas. This paper documents the diversity of ectomycorrhizal (ECM) fungi and collection as food. Forest fungi were collected from dipterocarp-dominated (mostly Dipterocarpus and Shorea spp.) primary and secondary forests in four provinces of northern Thailand, Chiang … [Read more...]
