Peat swamp forests in Sabah Malaysia are an endangered ecosystem. Forest fires log extraction activities urban and agricultural activities have reduced the area of natural peat swamp vegetation of Sabah. In the Klias Peninsula Malaysia forest fires in 1997-98 have destroyed about 100 ha of peat swamp vegetation. In March 2005 Sabah Forestry Department established a demonstration plot for the rehabilitation of burnt peat swamp vegetation. Eight 8 tree species namely Nauclea subdita Dyera polyphylla Dryobalanops beccarrii Lophopetalum multinervium Alstonia spatulata Gonystylus bancanus Hopea pentanervia and Mitragyna speciosa were selected based on the availability of planting materials. High density planting of seedlings was practised with a total of 4 469 seedlings planted on a 4 ha plot of burnt area in March 2005. During the assessment in July 2010 about 48 of the total seedlings planted survived. This is equivalent to 538 seedlings that had survived per hectare. Thus far based on the growth and survivorship Alstonia spatulata Dryobalanops beccarii Hopea pentanervia and Lophopetalum multinervium demonstrated encouraging performance. The availability of sufficient light is still the most important factor that influences the growth and mortality of seedlings.

Abstract

Peat swamp forests in Sabah Malaysia are an endangered ecosystem. Forest fires log extraction activities urban and agricultural activities have reduced the area of natural peat swamp vegetation of Sabah. In the Klias Peninsula Malaysia forest fires in 1997-98 have destroyed about 100 ha of peat swamp vegetation. In March 2005 Sabah Forestry Department established a demonstration plot for the rehabilitation of burnt peat swamp vegetation. Eight 8 tree species namely Nauclea subdita Dyera polyphylla Dryobalanops beccarrii Lophopetalum multinervium Alstonia spatulata Gonystylus bancanus Hopea pentanervia and Mitragyna speciosa were selected based on the availability of planting materials. High density planting of seedlings was practised with a total of 4 469 seedlings planted on a 4 ha plot of burnt area in March 2005. During the assessment in July 2010 about 48 of the total seedlings planted survived. This is equivalent to 538 seedlings that had survived per hectare. Thus far based on the growth and survivorship Alstonia spatulata Dryobalanops beccarii Hopea pentanervia and Lophopetalum multinervium demonstrated encouraging performance. The availability of sufficient light is still the most important factor that influences the growth and mortality of seedlings. Several issues related to the rehabilitation activities carried out are discussed.
