Reassessment of Forest Area and it's Scoring as a Permanent Production Forest
(IOP Conference Series: Earth and Environmental Science, 2018-05-08)Along with the increasing demand for tropical timber, the need for wood raw materials is not enough just to rely on natural forests, and therefore in the early 1990s began to be developed timber estates concessions. The ... -
Study on Land Rehabilitation at Mined Lands of PT Trubaindo Coal Mining, West Kutai, East Kalimantan
(Indonesian Wood Researc Society (IWoRS), 2013-11-09)In many cases, mined lands is not immediately ready to support plant growths due to bad drainages, soil structure disturbances, high temperature, uncontrollable overland flow, high erosion rate, lack understanding of ... -
Impact of logging and forest fires on soil erosion in tropical humid forest in East Kalimantan
(Center for International Forestry Research (CIFOR), 2001-02-02)Logging and/or forest fires cause a direct impact of reducing vegetation cover, and in many cases create a pre-condition for the increase of soil erosion rates during high rainfall. Such an increase in soil erosion rate ... -
