BIODIVERSITY OF PLANTS AND BIRDS IN RECLAMATION AREA OF PT BUKIT ASAM, MUARA ENIM, SOUTH SUMATERA
ABSTRACT: Mining activities
will reduce species diversity, whereas forest reclamation would restore the
species diversity, which was previously a forested area. This research was
conducted in PT Bukit Asam area, in 6 locations, and in natural forest, as a
comparison. The objective of this research was identifying biodiversity of
plants and birds in a reclamation area which had different planting years
through an approach of diversity indices of vegetation and birds (H'), index of
species similarity of plants and birds, and leaf area index (LAI). Research
results showed that secondary succession occurred in the reclamation area. The
value of plant diversity index in reclamation area of 1995 planting year
exhibited diversity values which approached that of natural forest, except for
undergrowth vegetation. Index of plant species similarity between reclamation
area and natural forest did not show any presence of similar communities, but
the reclamation area of 1995 planting year exhibited values of plant species
similarity indices at all strata, ranging from undergrowth vegetation,
seedlings, saplings, poles, and trees. Index of bird diversity in reclamation
area of planting the year 1998 possessed the highest value and approached that
of natural forest, namely 2.43. Reclamation area of 1998 planting year
possessed the highest similarity index of bird species, namely 50%. Reclamation
area of the planting year 1995 possessed LAI which approached natural forest,
namely 1.89. The older the planting
year, the larger was the value of LAI, except for the disturbed reclamation
area, namely reclamation area of 1996 planting year and reclamation area of
2001 planting year.
