Abstract

Macrophytic species diversity was studied in crude oil contaminated and non-contaminated sites within the Upper Burhidihing Reserve Forest. Species richness was 57 and 86 in contaminated and non-contaminated sites respectively. On the basis of importance value index (IVI), Cynodon dactylon (13.92), Cyperus cyperoides (12.75), Imperata cylindrica (10.01) were dominant ground-flora herbs in former sites. The IVI value of Axonopus compressus (7.90) was high in non-contaminated land. The distribution of most of macrophytes in contaminated areas was contiguous, in contrast to regular distribution of most of ground flora in other sites. The value of concentration of dominance (C) of the macrophytic flora at both sites was lower and index of diversity (H) was higher. The index of dissimilarity between the vegetation groups was high indicating the effect of crude oil contamination on vegetation.
