Species Diversity of Undergrowth Vegetation in Former Silica and Limestone Mining Land at PT Holcim Indonesia Tbk, West Java Indonesia

Ceng Asmarahman, Sri Wilarso Budi R, Imam Wahyudi, Erdy Santoso

Abstract


Open pit mining causes damage on ground cover vegetation, increase of erosion rate, decrease of land productivity, and decrease of soil fertility. Revegetation activity needs long period of time, so there is a need for planting of cover crops. The objective of cover crop planting is protecting soil from erosion.

The objectives of this research were learning species composition, species diversity and potency of undergrowth vegetation to be utilized as cover crop. Composition of undergrowth vegetation in ex-limestone mining land was higher as compared with that in ex-silica mining land. Species diversity (H) in each research location was categorized as moderate. Species evenness (E) in the two research locations were categorized as high. Species richness (R1) in the two research locations were categorized as high. Dominance index (C) in the two research locations were categorized as low. Soil properties in each location were categorized as not so fertile. Nutrient elements occurring in the two research locations were categorized as low.


Keywords
