Research on investment rate for protection forest establishment with some main native forest tree species in projects of programme 327<\/p>\n

Summary:<\/em>. The paper presents results of a research on investment rate for protection forest establishment with some main native forest tree species in projects of programme 327 nation \u2014 wide.<\/p>\n

Through studying investment rate in 30 forest plantation models in 4 regions to be protected (9 ecological zones) in 15 provinces and cities typically implementing projects of programme 327 the author evaluates the accomplishments and the remaining problems to be overcome regarding economics, techniques, models,\u2026; taking in to account the opinions of scientists, consultants as well as of the labourers the author presents the results of calculation of investment rate on planting, tending, management and protection of 1 hectare of forest in both planting systems (pure and mixed planting). Some recommendations are then made by the author on silvicultural techniques such as supplementation of procedures and technical measures and on economics such as economic and technical norms in forest planting and frame of investment rates for each forest economic zone in the whole country.<\/p>\n
