Figure 3.2: Forest Stratum Map of FMU 17A3.2 Forest InventoryAn inventory of timber resources was carried out over a period of 12 months, from April2003 to March 2004, covering all production compartments in FMU 17A. The inventorymethod used plots arranged continuously along a linear strip of up to 1 km in length. Alltrees > 40 cm dbh were enumerated on 10 x 20 m plots along the strip, while PotentialCrop Trees (PCTs = well-formed commercial trees with a minimum diameter of 5 cm)were selected within nested 10 x 10 m plots. Each compartment was inventoriedindependently using 3-6 linear strip lines, resulting in stand and stock tables forindividual compartments.The SFD assumes the standard that a compartment can be harvested when there is aminimum of 15 good quality commercial trees over 60 cm dbh per hectare. The SFD hasprojected the growth and mortality of each compartment in FMU 17A and has estimatedthe potential year of harvest for each compartment (see Appendix E). The projectionsshow that there will not be any harvesting within the next 10 years as much of the areahas been heavily logged over.15
