“…Pandy and Shukla (2003) stated reverse J distribution, indicative of uneven-aged stands among several dbh classes that correspond to the condition of natural forest and regeneration of trees and Rozas (2006) revealed this is in accordance with the idealized well-balanced population structure of the forests.…”

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 total of 45 families, 102 genera, 181 species, 3319 individuals were presented in the five 1-ha plot; this comprises 6.3% species, 19.2% genera and 42% families of the total tree taxa found in Peninsular Malaysia. Based on IVI, Vatica maingayi,Xanthophyllum affine,Vatica pauciflorawere the most dominant tree species. The families of Dipterocarpaceae, Polygalaceae,Guttiferae and Myrtaceae were among the most important families with high FIV. Based on dbh class, nearly 50% of the trees were distributed in the lower diameter class(5-15cm). According to heightlife-form categories, 53% of stems were belonged to small trees (7-15m). Species accumulation curve showedan asymptote at the third hectare.Keywords: Coastal hill forest, Importance value index, Basal area, Malaysia IntroductionTropical rainforest in five major regions (Corlett and Primack 2006), have the most diverse terrestrial ecosystems (Turner 2001) and extremely important for conserving biodiversity for the local and regional development and also for sustainable use of forests (Neshim et al.2009).Malaysian forests harbour a very large portion of diversity and forests have an important role in the country socio-economic development and environmental conservation (Nizam Khan and Zakaria 2005).This diversity is under great threat with total forested area in Peninsular Malaysia with 44.7% of its land area (Abdul Rashid 2005). There are 16 forest types based on altitude and soil types and distributed from the coastal lines to the mountain (Whitmore and Sayar 1992).The flora of Peninsular Malaysia contains the floristic elements of the Sunda Shelf and also of the mainland Asiatic species from seasonal climates (Saw and Chung 2004) and has been studied by several botanists. The first effort was done by Ridley (1922Ridley ( -1925 by Flora of the Malay Peninsula, while Whitmore and Ng (1972-1989) prepared the forest trees of Peninsular Malaysia in the Tree Flora of Malaya (Vol. 1 to IV).The current checklist catalogues reveals, Peninsular Malaysia has about 8893 taxa (species, subspecies and varieties) covering around 8200 native and 690 naturalised species (Sawet al. 2009) but the flora is not completely known and continuous botanical inventories is an on-going process.Tree species constitute a large proportion of the flora of the Malay Peninsula. From 8096 species that comprise the native flora of the Malay Peninsula (Turner, 1997), 2830 species are trees (35%) in which are distributed in 106 families and 532 genera (Ng 1991).Coastal hill forests are the climax vegetation. The main difference between the hill dipterocarp forests and lowland forests is the specific composition of the dominant of the upper str...

“…The Simpson index for subtropical pine agroforestry site is less stabilized and less active from a functional point of view(Odum and Saunders 1963).According to an investigation byMajumdar et al (2014), the natural forest site included 7,134 individuals overall, with a mean density of 648.55 stems per hectare. Tree density 422 individual ha-1 was observed to be higher in Doboka reserve forest than managed Sal Forest of Gorakhpur (404 individual ha¹)(Pandey and Shukla, 2003) and close to 438 individual per hectare recorded for moist Sal Forest in West Bengal (Kushwaha and Nandy, 2012) 484 individual per hectare recorded for Himalayan lowland Sal Forest.According to ndings fromWebb and Sah (2003),Pandey and Shukla (2003), the stand density of the low disturbed forest type was comparable with other Sal forests of India and Nepal Paul et al (2013). also reported that the highest IVI in Sal followed by Sinduri and the lowest IVI was found in Amloki preceded by Sisu which is very similar to the present study.…”

The rich plant biodiversity found in tropical regions faces significant threats due to extensive human activities. Factors such as deforestation, habitat deterioration, human settlement, excessive resource exploitation, the introduction of invasive species, pollution, and the interconnected effects of global climate change collectively contribute to a substantial negative impact on biodiversity in these areas. The study aimed to assess plant diversity in Madhupur Sal Forest, Bangladesh, comparing agroforestry, social forestry, and natural Sal Forest sites. Using 90 random 10 × 10 m² plots, 47 species were recorded, including 31 trees, 5 shrubs, 6 herbs, and 5 climbers. Anacardiaceae, Arecaceae, Euphorbiaceae, and Fabaceae were prominent families, each with a species richness of 3. Agroforestry exhibited the highest species richness (14), Shannon-Wiener index (1.37), and Simpson's index (2.41) among plantation sites, surpassing social forestry. Social forestry, however, showed higher tree stand density (1673 trees/ha), tree basal area (28.67 m²/ha), and species evenness (0.67) than agroforestry. The natural Sal Forest site displayed the highest species richness (33), tree basal area (41.21 m²/ha), Shannon-Wiener index (2.15), and species evenness (0.78). Overlapping species occurred between agroforestry and social forestry (5 species), and agroforestry and natural Sal Forest (1 species), resulting in a higher similarity index (19%) for the former. No species overlapped between social forestry and natural Sal Forest. The study concluded that natural Sal Forest exhibited the highest diversity (2.15), while agroforestry proved beneficial for biodiversity compared to bare land.
