| dc.description.abstract | The intrusions of weedy and exotic species into disturbed and undisturbed peat swamp forests can cause a major problem which need proper attention. The study on the diversity and ecology of weeds in 20 swamp forests of Peninsula Malaysia has found that the agricultural areas on reclaimed peat swamps have the highest diversity and composition of weedy species compared with other types of peatland forests. A total of 54 families, which comprising of 97 genera dan 132 species have been recorded from ten peat swamps and ten freshwater swamps. Broad-leaves weeds are the most dominant type of weedy species recorded with 33 families, 54 genera and 69 species. Clidermia hirta and Melastoma malabathricum (Melastomataceae) are the most dominant species. in tenn of their presence at all study sites. Three noxious aquatic weeds, Salvinia molesta, Hydrilla verticillata and Lemna perpusilla have been recorded in peat swamp and fresh water swamp areas. The intrusion of the most noxious semi aquatic weed, Mimosa pigra in two sites of peat swamps and one site of freshwater swamp have shown that the distrubution of this species is still under controlled. However continous monitoring should be conducted to ensure that this particular species will not poses a threat to the population of endemic species and also will not spread to other areas. The comparision between peat swamp forests and freshwater swamps has shown that freshwater swamps harbour more weedy species number (135 species) than the peat swamp areas. The Clustering and Principle Component Analysis revealed the similarity of types, sources and phase of disturbances between the study sites based on presences and also distribution of weedy species in the study locations. | en_US |
