Tree basal area for 20 species according increasing order of Basal area in Sungai Pinang Permanent Forest Reserve in Pulau Pangkor
Source publication
Tree species composition and structure of a coastal hill forest in Sungai Pinang Permanent Forest Reserve in Pulau Pangkor at Perak was studied based on the data from five 1-hectare plots. All stems with a diameter at breast height (dbh) ? 5cm enumerated, identified and their height weremeasured. The mean stem density was 659 (stems ha -1 ), and a...

Natural regeneration status of native tree species of Himchari National Park (HNP) was assessed through stratified random sampling method during January 2017 to May 2018. For regeneration study, about 51 subplots (5m×5m) were taken at the centre of each of the 51 sample quadrats (20m x 20m). A total of 760 seedlings of 41 species under 21 families...
Mt. Tago Range in Bukidnon has been subjected to deforestation and forest fragmentation due to logging ca. 35-40 years ago or as direct result of land conversion for agriculture, human settlements and wildlife product harvesting. It is currently not a protected area. This study aimed to provide data on the tree species diversity, structure, composi...
A forest inventory was conducted in lowland rainforest on the southwestern border of Manongarivo Special Reserve, nothwestern Madagascar. At 220 m elevation, a one hectare area (20 X 500 m) was sampled for all trees with a dbh of 10 cm or more. 90 species represented by 728 individuals, with a total basal area of 22.4 m2ha, were recorded in the plo...

... Previous researches on tree species distribution and diversity on Malaysian Peninsular islands were collectively done at Tioman (Latiff et al., 1999), Langkawi (Rohaiza, 2011), Pangkor (Ghollasimood et al., 2011) and Redang (Khairil et al., 2012). Besides research on tree species diversity and composition at Pulau Perhentian had also been conducted recently by Pesiu et al., (2015) and Pardi et al., (2018). ...
... A recent study by Pardi et al., (2018) also found Rubiaceae was the most abundance family followed by Ebenaceae and Guttiferae at Perhentian Islands. Similar result also was reported by Ghollasimood et al. (2011) which Rubiaceae was the most abundance family at a coastal hill forest in Pangkor Island. Rubiaceae is reported as one of the five most species-rich flowering plant families, and it is not surprising because this family is widely distributed in tropical region (Whitmore 1984;. ...
Perhentian Island is a famous ecotourism site in Terengganu, Peninsular Malaysia. However, the increase in tourism activities such as chalets development and deforestation had contributed to habitat degradation in some areas on Perhentian Island. A study was conducted to determine the composition, diversity and aboveground biomass of the trees species at the coastal and inland forest of Perhentian Island, Terengganu. Three plots of 20 x 30 m were established on each inland and coastal forest of the island which altogether study plot was 0.36-hectare and all trees with the size of one cm diameter and above were recorded. Inland forest has higher individuals with 844 individuals representing 70 species from 48 genera and 30 families. A total of 367 individuals, representing 93 species from 71 genera and 30 families were recorded at the coastal forest. The Shannon-Weiner Diversity Index (H') was high in both forest plots with 3.20 (H 'max = 4.25) at the inland forest and 3.97 (H' max = 4.53) at the coastal forest. The Shannon Evenness Index (E') in the inland forest plots was 0.71 and 0.88 at coastal forest. The total above-ground biomass at the inland forest was higher than the coastal forest with 600.51 t/ha and 364.01 t/ha respectively. Seven tree species which considered endemic to East Coast Peninsular to Malaysia were found at Perhentian Island. Besides, a total of 23 species of 125 species recorded found were listed in the IUCN Red Data Book.
... Overall, the most speciose family within the 0.5-ha plot was the Rubiaceae (11 species) followed by Ebenaceae (9 species) and Guttiferae (8 species) while 8 families were singletons (represented by only one species) which were Apocynaceae, Celastraceae, Elaeocarpaceae, Fagaceae, Ixonanthaceae, Lecythidaceae, Oxalidaceae and Simaroubaceae. Similar observation have also reported Rubiaceae as the most speciose family of a coastal hill forest in Perak [24] as well as in the oldest forest reserve in Bukit Nanas Forest Reserve, Malaysia [25]. This is not surprising because Rubiaceae is reported as one of the five most species-rich flowering plant families comprising of 13,000 species; 620 genera, more than 40 tribes, and three subfamilies that is widely distributed at all continents including on the Antarctic Continent but most taxa occured in tropical or subtropical areas. ...
The Perhentian Island Archipelago comprising of 11 small islands is located in the state of Terengganu are among the biodiversity rich localities in Peninsular Malaysia. Perhentian Besar with approximately 867 hectares is one of the inhabited island and become the centre of tourism besides Perhentian Kecil. Island is well known as a place for many endemic and endangered living organism as previously demonstrated on other similar forested islands in Southeast Asia. However, there is little attention and effort of protection has been received by the terrestrial ecosystems that reside nearby the coastal. Thus, the present study investigates on tree diversity, stand structure and community composition in the island of Perhentian Besar, Terengganu. Forest plot of 0.5 hectare was established to analyze the floristic composition of tree taxa. The plot was divided into 10 subplots of 25m x 20m. All trees with 5cm diameter breast height (dbh) and above were tagged, measured for dbh size, recorded and identified. Voucher specimens were taken for further verification purposes. A total of 102 tree species were recorded comprising of 28 families and 65 genera. Rubiaceae had the highest number of species (11 species) and with regards to relative dominance, Shorea leprosula (Dipterocarpaceae) gave the highest importance value index (IVi) for species with a value of 8.45%. The Shannon-Weiner Diversity Index (H’) was considered high in the present study with 3.94 (H’max = 4.62) and the Evenness Index (E) value of 0.85 indicated that all species in the present study are almost equally abundant. The forest stand structure had a reverse J-shaped curve for tree size-class distributions as frequently observed in many natural forests, which indicated that the forest stand in the study site had a good recruitment patterns and also a main feature of matured forest in Peninsular Malaysia. The present study will help us to understand the pattern of tree species composition, diversity and forest ecosystem dynamic in Pulau Perhentian Besar.
