Solution for planting protective forest shelterbelts in the sandy land area along the coast of Vietnam
December 9, 2010 by
Dang Van Thuyet Science and Planning Division Forest Science Institute of Vietnam Vietnam has a coastline of 3260km, running from Mong Cai to Ha Tien over 25 provinces and cities. This is a harsh ecology, causing sand hazards and a powerful mobile menace to crops and people living on coastal sandy areas. This article is drawn from the results of research investigating, evaluating, arranging and monitoring experiments on afforestation and integrated analysis of … [Read more...]
The results of research on seedling propagation of Garcinia fagraeoides and Cinnamomum balansae species by seeds and cuttings
December 9, 2010 by
Ha Van Tiep Northwest Center for Forestry Science and Production Garcinia fagraeoides species belongs to the Clusiaceae family and Cinnamomum balansae species in Lauraceae family. Both are big indigenous tree species with high ecological and economic value in the Northwest region of Vietnam. Presently, two of these species are extremely degraded in nature by unplanned harvesting, and there is limited natural regeneration due to exhausted mother trees. Therefore, studying … [Read more...]

Research on basic biophysiology characteristics of Lithocarpus ducampii AND Machilus odoratissima
December 8, 2010 by
Ha Thi Mung1, Le Quoc Huy2 (1: Research Center on Forest Ecology and Environment 2: Center for Biotechnology in Forestry) Two woody tree species, Lithocarpus ducampii A.Camus and Machilus odoratissima Ness, which have high a economic value are being harvested excessively. Both of them are suitable trees chosen for planting in Vietnam, especially for improving poor forest. Some researchers have studied Lithocarpus ducampii and Machilus odoratissima since … [Read more...]
Evaluation of resources and endangerment of forest tree species of Vietnam
December 8, 2010 by
Nguyen Hoang Nghia Forest Science Institute of Vietnam There are more than 50 conifer species in Vietnam, of which 33 of them are native, so they occupy a priority place in conservation and development programs. Most conifer species occur in very difficult site and climatic conditions; natural forest is still degraded or fragmented, and natural regeneration is bad, therefore genetic conservation of conifer species requires a high priority. Quite a high number of conifers of … [Read more...]
Completmentary survey of species compositton for main Bambo species in Vietnam
December 8, 2010 by
Le Viet Lam Forest Plant Resource Research Division Forest science institute of Vietnam Vietnam has been extensively explored for botanical specimens and ecological understanding. Plant specimens are housed in a number of international herbaria but the information on the taxonomy of Vietnamese bamboos is very limited. The systematic study of bamboos is a very difficult task due to unpredictable and sudden flowering and scarce seed production. Most of the works are based on … [Read more...]
