| Summary: | Malaysian forests are familiar for their diversity in flora and fauna species which have
economic value. The most significant factor that contribute to the increase in economic
values in a forest area is its timber resources. The total areas of jungle reserves in this state
is 241,568.2 hectares, or 30.5% from total state forest. Diversification of sources of high
value timber in the forest reserve will invite the intrusion of illegal loggers, which will
have negative impacts on the ecosystem. Thus, a study was conducted in Virgin Jungle
Reserve at Sungai Lalang forest in Compartment 24 (C.24) and Ulu Gombak forest in
Compartment 23 (C.23) in Selangor. The study objectives were to identify the composition
of trees, to estimate the stumpage value based on the current market value, and to estimate
the total stumpage value in the forest catchment areas. Data was collected by counting
every tree with a diameter more than 10 cm as sample data. Estimated stumpage values
were measured by calculating timber values based on current market price which is
different for each species. 418 trees with 224 species, 130 genus and 50 families per hectare
in C.24 were enumerated. The most abundant species in C.24 was Elateriopermum tapos,
while the largest families included Euphorbiaceae, Dipterocarpaceae and Lauraceae. The
stumpage value of tree species diversity in this compartment was RM 194,520.70 per
hectare. Meanwhile, 402 trees with 190 species, 108 genus and 46 families per hectare
were enumerated in C.23. The most abundant species was Aidia densiflora while the
largest families were Euphorbiaceae, Rubiaceae and Lauraceae. The stumpage value of
tree species diversity in this compartment was RM 147,360.00 per hectare. Selangor’s
policy that has put a stop in issuing logging licenses in 2009 is seen as bringing positive
impacts, whereby the study findings have seen an increase in species value, biological
diversity and stumpage value in both study areas compared to previous studies. |
