Fragmented forest in tropical landscape--the case of the State of Selangor, Malaysia
This paper presents the pattern and changes of fragmented forest in relation with changes of total forest cover in the state of Selangor in three decades.In this study, inventoried forest cover maps of Selangor in 1971/1972, 1981/1982 and 1991/1992 produced by the Forestry Department of Peninsular Malaysia were digitized to examine the changes in area and number of fragmented forest.Results showed that in 1971/ 1972, 16 fragmented forests were identified in Selangor.All fragmented forests were identified as dipterocarp forest.A decade later the number of fragmented forests increased by approximately 44% (23).Of the 23 fragmented forests, two were peat swamp forests whereas the remaining were dipterocarp forests.In 1991/1992 the number of fragmented forests (12) was reduced by 47.8%.Two of the fragmented forests were identified as peat swamp forest, seven dipterocarp forest and the other three was mixed of dipterocarp forests and plantation forests.Fragmentation of both dipterocarp and peat swamp forests occurred profoundly during the period between 1971/1972 and 1981/1982, which consequently increased the number of fragmented forests compared with before the period of 1971/1972 where fragmentation happened only at dipterocarp forests.However, many fragmented forests vanished between the 1981/1982 and 1991/1992 periods.
