that provides the main forest structure and largely contributes to the stem numbers andbasal area. Dipterocarp species are also dominating the residual forest canopy.Figure 2.4: Original forest formation in FMU 17AThe second largest formation is ultramafic forest (UF), which once covered an area of13,403 ha (27 % of FMU 17A), mainly found in Sg. Pinangah FR. The ultramafic soils arecategorized as marginal, deficient in phosphorus, potassium and calcium; usually containhigh concentrations of magnesium, chromium, cobalt and nickel. These areas are usuallypredominated by a series of high ridges, steep slopes (above 25°) and V-shaped valleys.The coverage of lowland and upland UF areas are 5,896 ha (12 %) and 6,574 ha (13 %) ofthe total FMU 17A area, respectively.On higher elevations, the lower montane forest covers at least 114 ha or 0.2 % of FMU17A. In alluvial fans, which derive from upland or montane ultramafic soils, usuallyassociated with streams (Binalik Association), the forest is classified as lowland Alluvial-Ultramafic Forest. This forest naturally shows a broken canopy structure with amixture of tree species commonly found in MDF and UF, and pockets of open areainfested with climbing bamboos. To a small extent, the forest occurred on broad alluvialterraces to gentle undulating terrain. Collectively, the forest covered an area of 808 ha(1.6 % of total FMU 17A area). The Upland Kerapah-Ultramafic Forest, (1,128 ha) or 2.311
% of the total FMU 17A area is restricted to the northwest and extends to Tawai FRwith flat to gently sloping terrain.2.4.2 Diversity of FloraA survey conducted by the Forest Research Centre (FRC) has recorded a total number of1,502 plant species/taxa from 140 plant families (including those retrieved from theherbarium specimen record at SAN). Of these, a total of 160 species are endemic toBorneo, including 21 species that are endemic to Sabah. Most of the plant species underthis category are confined to ultramafic substrates around Sabah (e.g. Ulu Tungud, Mt.Silam, Kinabalu etc.). However, none of the species recorded from the survey is endemicto FMU 17A. Some fruit trees, like Durian (Durio spp.), Kawang (Shorea mecistopteryxand Shorea pilosa), Mango (Mangifera spp.), and Rambutan (Nephelium spp.) were found inthe area.Past logging activities are believed to have increased the threat to those plants thatwere identified or categorized as threatened species. Most of the identified endangeredspecies from the study are from the Dipterocarp family.2.5 Past Management2.5.1 Timber production and implicationsCommercial exploitation in FMU 17A started as early as the 1970s’. This forestexploitation continued until the year 2002. The issuance of short-term logging licensesat very short intervals, as well as poor logging practices, have resulted in over-logging.Historic records of the volumes of commercial timber extracted from FMU 17A are notcomplete. However, it is estimated that more than 6.0 million m³ of commercial timberwere removed from Tangkulap Forest Reserve since the early 70s’ equating to an averageof 120m3/ha being extracted.As such most of the forest area is considered degraded and would need timber standimprovement to enable harvesting to resume within the next 20 years. The main focus ofthe management system will be through restoration of severely degraded areas based onintensive methods such as planting of fast growing native species in blocks of about 30ha or less to form a mosaic of planted and natural regenerating forest areas.12
