Abstract:
Revegetation with woody plants is a strategic effort to avoid the negative impacts
of coal mining and at the same time improve the utilization of ex-mining land. This study aimed
to analyze the dominance, diversity, and evenness of woody plant species planted in the
reclamation area of PT. Adaro Indonesia. At 4 locations of reclamation area,paths consisting of
10 plotswere made. In each plot (20 x 20) m2
, only 1 plot (10 x 10) m2
, only 1 plot (5 x 5) m2
, and
only 1 plot (2 x 2) m2 were successively made. The plot (20 x 20) m2 was used to record tree
level, (10 x 10) m2
for the pole level, (5 x 5) m2
for the sapling level, and (2 x 2) m2
for the
seedling level. Dominance was determined by important value index, while diversity and
evenness were based on the Shannon index. Fourteen of the 21 woody plant species were
intentionally planted and the remaining 7 species grew spontaneously. Of the 14 species,
64.29% were legumes and 35.71% non-legumes. The dominance, diversity and evenness vary
according to their level of growth and location. The highest species diversity does not always
coincide with the highest species evenness.
