KEANEKARAGAMAN VEGETASI DI HUTAN LINDUNG GUNUNG SEMAHUNG DESA SAHAM KECAMATAN SENGAH TEMILA KABUPATEN LANDAK
ABSTRACT: Efforts to inventory
the wealth of forest resources are still needed. There are stillmany areas that
have potential especially plants than can be utilezed in order to preserver the
forest. Thisresearch aims to determine the Diversity of Vegetation that exist
in the Protected Forest ofGunung Semahung, Village of Saham, Sengah Temila
Sub-district, Landak District. This research uses survey method by placing
double plot where sampling is placed in accordancewith the predetermined
direction. The research plots are systematically laid out. Number ofpaths made
as lines with a length of 1000 meters, each path there are 25 plot observationsmade
in accordance with the direction of the compass, so the overallarea is 2 Ha. 20
x 20 mobservation plot to measure tree level, 10 x 10 m for measuring pole
level, 5 x 5 m formeasuring stake level and 2 x 2 m to measure seedling level.
The distance between plots is 20 m.The data obtained are then calculated
relative density and density, relative frequency andfrequency, dominance and
relative dominance, to obtain an Important Value Index (INP).Further calculated
Dominance Index (C), Type Diversity Index (H) and Tpe Abudance Index (E). The
Important Value Index (INP) at the dominant seedling level is Garcinia
xanthochymus(16,39). The Important Value Index (INP) at the most dominant
stakes is the Durio zibethinus(15,68). The Important Value Index (INP) at the
most dominant pole level is the Shorea acuminatissima (19,59). The Important
Value Index (INP) at the most dominant tree level is theDiosphyros maingayi
(36,36). The highest Dominity Index at the tree level is 0,1747. Thehighest
Diversity Index at the stakes level is 1.5510. The highest Type Abundance Index
at thepole level is 0.9625.
