| 总结: | The study was conducted in Ayer Hitam Forest Reserve (AHFR), Puchong,
Selangor to assess the floristic composition, stand attributes (including basal
area, stem density, volume, above-ground biomass) and the tree species
distribution. Besides that, the study aims to recognize the conservation status
of tree species, potential increment of the species within the sampling area
and it regenerating level by using the summation method.
The enumeration of trees >5 cm dbh in the 5-ha plot recorded 6,621 trees
which belong to 50 families, 148 genera and 319 species. Euphorbiaceae in
this plot was found dominant in genera and tree stems but Myristicaceae has
the most number of species with 27 species. Agrostistachys longifolia var.
longifolia recorded 7.0% of all trees was the highest in stem number.
Shannon-Weiner diversity i ndex, H' of the area was calculated at 4.74. I n this
study, 4.4% of the endemic species for Peninsular Malaysia and 9.4% of the
tree species was recorded for the first time for the state of Selangor. Only
Artocarpus lowii was identified as uncommon and Canarium sumatranum is a
rare species occurring in this area.
Ayer Hitam Forest Reserve stratification and the stand density could be
divided into five classes. The secondary species found occurring in this plot
was 4.1% of the tree species. The total basal area, volume and aboveground
biomass of the trees in 5-ha plot was 161.7 m2, 6,316.5 m3 and
1,777.2 t respectively. Every addition of a hectare in the contiguous area in
t h e AHFR shows that there is an increase accumulative num ber o f species
with the ranges of 9-35 species. |
