KEANEKARAGAMAN JENIS VEGETASI PENYUSUN TEMBAWANG DI DESA NGARAK KECAMATAN MANDOR KABUPATEN LANDAK
Abstract: Tembawang is a
system of land use by Dayak tribe community in West Kalimantan which is
considered as unique ecosystem because it holds very high value. Tembawang in
Ngarak has been converted into shifting cultivation and tree felling so that
caused the reduction of vegetation type in the tembawang. This study aims to
examine the diversity of vegetation species found in tembawang in Ngarak,
Mandor Sub district of Landak District. The benefit of the research is to
provide information on the diversity of vegetation types found in tembawang in
Ngarak. The results showed that the diversity of vegetation type of
constituents in Ngarak village there were 54 species of vegetation grouped into
22 families identified. Levels of seedlings in hill tembawang 21 species, while
in tembawang lowland 6 species. The level of stake in hill tembawang 22
species, while in the lowland tembawang 16 species. Level pole in hill
tembawang 14 species, while in tembawang lowland 11 species. The tree level in
the hill tembawang 18 species, while in the lowland tembawang 11 species. The
dominance index (C) for all growth rates in Ngarak village has low index of
dominance because it is still far from the highest dominance value (C = 1),
while the diversity index (H ') in hill tembawang shows diversity level which
is classified as abundant 1 ≤ H '≤ 3 except at the pole level, the diversity is
low because of the value of 0.84.
