Tay Soon Poh, . and P. B. L. Srivastava, . Crop composition and density after thinnings and before final felling in the Matang Mangrove Reserve Perak. pp. 95-104. ISSN 0126-6128

The study reports the composition of the crop and growth pattern of important species in terms of height density diam eter and basal area during the rotation period in some productive stands of the Matang Mangrove Reserve of Peninsular Malaysia. In all seven stands representing areas before thinning I thinning II thinning III and before final felling were sampled. A ll the sites were potential Rhizophora spp. stands belonging to Watsons inundation classes II and III. The crop was almost pure and uniform dom inated by Rhizophora apiculata. Brugiera parviflora the most important associate was found to constitute less than 10 per cent o f the crop in most of the sampled plots. On an average there were 3236 2107 1321 and 830 stem s per hectare before thinning I II III and final felling respectively. Mean DBH fo r the respective stages were 8.28 cm 9.65 cm 13.90 cm and 17.45cm. When compared with earlier estimates it appears that there is a large scale mortality between 2 and 15 years of crop. There is a need to study the mortality rate and its causes during this period which might have a bearing on the thinning schedules and rotation period.

Abstract

The study reports the composition of the crop and growth pattern of important species in terms of height density diam eter and basal area during the rotation period in some productive stands of the Matang Mangrove Reserve of Peninsular Malaysia. In all seven stands representing areas before thinning I thinning II thinning III and before final felling were sampled. A ll the sites were potential Rhizophora spp. stands belonging to Watsons inundation classes II and III. The crop was almost pure and uniform dom inated by Rhizophora apiculata. Brugiera parviflora the most important associate was found to constitute less than 10 per cent o f the crop in most of the sampled plots. On an average there were 3236 2107 1321 and 830 stem s per hectare before thinning I II III and final felling respectively. Mean DBH fo r the respective stages were 8.28 cm 9.65 cm 13.90 cm and 17.45cm. When compared with earlier estimates it appears that there is a large scale mortality between 2 and 15 years of crop. There is a need to study the mortality rate and its causes during this period which might have a bearing on the thinning schedules and rotation period.
