KOMPOSISI JENIS TUMBUHAN BAWAH DI LAHAN REVEGETASI PASCA TAMBANG BATU BARA
Abstract: One component of the
tropical rainforest ecosystem is the understorey plants. The presence of
understorey plants in post-coal mines will accelerate restoring disturbed
forest land. This research aims to determine the condition of both understorey
and natural pioneer species at the post-coalmine land, in terms of species
richness and its diversity. The data was collected by using the ploted-line
method, mainly over revegetated land. The result of understorey species at
revegetated land is 43 species, while from its surrounding is even 71 species respectively. The data
showed that the number of understorey species at revegetated land is lower than
its sorrounding. The condition is probably close related to the prior status of
mining land as plantation and limited production forest. However, in compare
with baseline data at the early time of revegetation activity, the number of understorey
species was more diverse at the time of study. During inventory at the
revegetation land was also found four species of pioneer plants namely
Homalanthus populneus, Macaranga gigantea, Macaranga tanarius, and Trema
orientalis. Post-coalmining land is looking as
severe degraded land following intensivelly managed, those consequenly
bring through a limited number of understorey species
