Tree species composition of mixed dipterocarp and intermediate kerangas-alluvial forest : a case study at Mount Jagoi, Bau, Sarawak
Three different forests of Jagoi were involved in this study. These are the undisturbed forest of Jagoi, Pinungan, at 235 – 281 m altitude, the logged-over dipterocarp forest, Dorod Spolup, at 198 – 205 m altitude, and the heath forest, Dorod Po Aup, at 35 – 65 m altitude. Po Aup was also represent...

| Summary: | Three different forests of Jagoi were involved in this study. These are the undisturbed forest of Jagoi, Pinungan, at 235 – 281 m altitude, the logged-over dipterocarp forest, Dorod Spolup, at 198 – 205 m altitude, and the heath forest, Dorod Po Aup, at 35 –
65 m altitude. Po Aup was also represented by alluvial riparian forest. Dipterocarpus rigidus, Artocarpus odoratissimus, and Hevea brasiliensis dominated at respective locality. Species diversity was greatest at Spolup as expected of a disturbed forest. Though lacking in volume, Spolup achieved decent regeneration in 20 years but comparison with the conditions prior to logging
cannot be done due to lack of pre-logging documentation of the area. The strata between Pinungan and Spolup have similarities. In addition, the heath forest of Po Aup also depicted similar strata to both of the dipterocarp forest studied. The complexity of Po Aup heath forest can be distinguished by the number of individual, its volume, species composition and its variation from typical heath forest. Reasons for this is unknown and finding out would require a bigger plot size to fully examine all attributes of Po Aup heath forest. |
