ABSTRACT

The research aim to detects the structure and composition of nature forest vegetation in
Trisula Resort of Bromo Tengger Semeru National Park. This watchfulness is carried out at Trisula
Resort nature forest of Bromo Tengger Semeru National Park, broadly 5.222,737 ha, in June 2011.
The methods that used is stripe method federation and line compartment method so that in
stripes made sample terracing. The vast sample compartment to each growth level covers: seedling
of the size compartment 2 x 2 m, saplings of the size compartment 5 x 5 m, pole or little tree of the
size compartment 10 x 10 m, and tree of the size compartment 20 x 20 m. And then in this compartment
done kind identification, total, count diameter (dbh), and tall.
The forest vegetation structure at Trisula Resort of Bromo Tengger Semeru National Park in
several blocks that is Amprong, Jarak Ijo and Coban Trisula, show tropical forest generality, where
does tree closeness of the size smaller always higher compared of the size larger ones tree. Conditon
be dinamic cycle existence instruction as tropical forests individuality in general. Recorded as much
as 178 species from 77 kins in sample as big as 0.208 ha, several found flora endemic BTN-BTS like
Magnolia blumei PRANTL, Cyathea tenggerensis (R.) Copel, and Cephaelis ipecachuanha TUSSAC.
While formation and forest composition in ngadas block show secondary forest conditon. in this
block chockablock ground covers has expansive and flame resistant like Imperata cylndrica L. ,
Eupatorium odoratum L., and many kind of Scrubs. Strightened kinds like Casuarina junghuhniana
Miq. , Acacia decurrens Willd. , Albizia lophanta (Willd)., and Vaccinium varingifolium (Bl.) Miq.,
be kinds general are met at these area. Then highest important values that has by several kinds in
each block, show that kinds has part level or big importance as the communities composition
composers part. The highest kind of variety level for stage seedlings up to tree that by variety index
in Coban Trisula block, that is in tree as big as 3,7, with similiarity as big as 0,95, furthermore in
pole as big as 3,56 with similiarity as big as 1, then in pole as big as 3,3 with similiarity as big as 0,9
and latest in seedling with value 2,8 with similiarity index as big as 1, while highest kind unity level
for ground covers found in block amprong with value 3,53 and similiarity index as big as 0,89.
