TIMBER HARVESTING


PLANNING THE INTRICACIES OF TIMBER HARVESTING

Raw data are gathered and collected through fieldwork, whereas, complementary data are derived from aerial photographs and satellite data from SPOT and Landsat TM images. Varied data images are compiled into Forest Inventory database, enabling forest managers to layout short-term and long-term timber harvesting schemes that will eventually ensure the continuous supply of logs to the downstream wood processing plant.

Before preparing its 10- year master plan (RKUPHHK), Sarpatim conducted a comprehensive forest inventory (IHMB) to determine the condition of its timber stands as a means of monitoring the trend of sustainability of the stocks in natural forest (IUPHHK).

For detailed and precise annual operations plan, a 100% census of trees having diameter of 20 and up cm is conducted simultaneously on the ground with the topographic survey.

Results are then plotted in computers using Geographic Information System software generate tree location and contour maps at 1:1000 scale. The map will be a tool and guide for the Forester to design effective and efficient forest road construction and an essential and accurate guide for tree fallers too. With it as handy device, they could minimize and reduce residual tree damages before and after felling operations.

The harvesting/operations plan is an essential tool for good forest management because it establishes the basis for transparent accountability of activities. It is reviewed and approved by the Provincial Forestry Agency where the concession is located.

Global Positioning System technology is likewise used to pinpoint areas cruised with accuracy and for monitoring data collection.


HARVESTING TIMBER WITH CARE

Reduced Impact Logging (RIL) techniques in timber harvesting is applied in the concession's harvesting operations in order to further minimize the negative impact on the remaining/residual timber stock, soil, water quality and quantity and on the environment; to enhance the efficiency of the company's performance in timber harvesting operations. It is also designed to optimize the utilization of timber and ensure that log volume recovery is maximized as well as optimize timber product output with maximum cost efficiency.

The preparation of the harvesting operations plan contributes largely to the success of RIL in significantly reducing logging damage on forest ecosystems. The harvest planning process takes into account the ecological, environmental and socio-economic features of the concession.
