Influence of the Edge Effect and Other Selected Abiotic Factors on Tree Seedling Density and Species Richness in a Tropical Forest in Singapore
Influence of the Edge Effect and Other Selected Abiotic Factors on Tree Seedling Density and Species Richness in a Tropical Forest in Singapore Galen Tiong Ji Liang, Eun Jung Min, Jeremy Yu King Yan NUS High School of Mathematics & Science Little Green Dot Student Research Grant PROJECT REPORT submitted to Nature Society (Singapore) Junior College Category Year 4 & 5 2810 words 1 Influence of the Edge Effect and Other Selected Abiotic Factors on Tree Seedling Density and Species Richness in a Tropical Forest in Singapore Tiong Ji Liang Galen1, Eun Jung Min1, Jeremy Yu King Yan1, Alex Yee Thiam Koon2 Lee Siak Cheong1, Hugh Tan Tiang Wah2 1NUS High School of Mathematics and Science, 330 Clementi Avenue 1, Singapore 129953 2Botany Laboratory, Department of Biological Sciences, National University of Singapore 14 Science Drive 4, Singapore 117543 Abstract Though the edge effect in tropical forests is a well-researched topic, studies pertaining to its influence on seedling dynamics are rare. We examined the effect of distance-to-edge and environmental variables on seedling density and species richness. We constructed 48 1 × 1 m seed plot quadrats in the MacRitchie Reservoir forest area, where we measured leaf litter depth, canopy cover and soil pH. All woody stemmed seedlings > 20 cm to < 1.3 m tall were tagged, identified and were measured for their basal stem diameter and height. Our analyses demonstrated that the edge effect influenced seedling species richness but not density, with lower species richness observed in the edge compared to the forest interior. Overall, seedling density was affected by canopy cover, leaf litter, the cover-litter interaction term, while species richness was primarily influenced by distance to edge and canopy cover. -

Awang Noor Faculty of Forestry, Universiti Putra Malaysia 43400, Serdang, Selangor, Malaysia Tel: 98-915-756-2704 E-mail: [email protected] Received: September 7, 2010 Accepted: September 20, 2010 doi:10.5539/jas.v3n3p111 Abstract Vascular plant species and diversity of a coastal hill forest in Sungai Pinang Permanent Forest Reserve in Pulau Pangkor at Perak were studied based on the data from five one hectare plots. All vascular plants were enumerated and identified. Importance value index (IVI) was computed to characterize the floristic composition. To capture different aspects of species diversity, we considered five different indices. The mean stem density was 7585 stems per ha. In total 36797 vascular plants representing 348 species belong to 227 genera in 89 families were identified within 5-ha of a coastal hill forest that is comprises 4.2% species, 10.7% genera and 34.7% families of the total taxa found in Peninsular Malaysia. Based on IVI, Agrostistachys longifolia (IVI 1245), Eugeissona tristis (IVI 890), Calophyllum wallichianum (IVI 807), followed by Taenitis blechnoides (IVI 784) were the most dominant species. The most speciose rich families were Rubiaceae having 27 species, followed by Dipterocarpaceae (21 species), Euphorbiaceae (20 species) and Palmae (14 species). According to growth forms, 57% of all species were trees, 13% shrubs, 10% herbs, 9% lianas, 4% palms, 3.5% climbers and 3% ferns. -

FOREST ASSESSMENT OF LOWER SUGUT FOREST RESERVES FOREST ASSESSMENT OF LOWER SUGUT FOREST RESERVE Reuben Nilus & John B. Sugau Sabah Forestry Department February 2015 INTRODUCTION Lower Sugut Forest Reserve (LSFR) is a Class I Protection Forest with a total area of 8,680 ha (Fig. 1). The Beluran District Forestry Office administers the reserve. The Forestry Department through the Forest Research Centre has conducted forest quality assessment in Lower Sugut FR from the 22th till 27th September 2014. The objective of the survey is to determine vegetation quality in the various forest types. This information will provide forest ecosystems background for Lower Sugut Forest Management Unit. STUDY SITE Location and access Lower Sugut FR is situated about 75 km northwest of Sandakan town (Fig. 1). It is geographically located between latitude 06° 16’ 44.9”–06° 24’ 32.3” N and longitude 117° 02’ 19.6”–117° 21’ 14.9” E. The reserve can be accessed through Sapi–Nangoh highway and traverse through IJM oil palm estate; and also through the sea by boat. Soil There are seven major soil association underlie Lower Sugut FR (Fig. 2). About 69% of the FMU is affected by high water table: 30% under tidal influenced and the soil is categorised as Weston association; 39% under freshwater influenced and categorised as Sapi (26%), Kinabatangan (12%) and Klias (15 ha) soil associations. The other soil associations that consider as dryland, such as Maliau and Tanjung Aru associations that underlie 19% and 11% of the reserve area, respectively, are categorised as intermediate fertily in plant nutrient aspect (Acres et al., 1975). -
The Taxonomy and Conservation of Palaquium in Brunei
The taxonomy and conservation of Palaquium in Brunei F. Culverhouse 2013 Thesis submitted in partial fulfillment for the MSc in the Biodiversity and Taxonomy of Plants ii Abstract The genus Palaquium Blanco. represents over half the Sapotaceae species found in Brunei and is an important component of Brunei’s forests, growing in six of the seven major forest types. This thesis provides an updated checklist of Palaquium from Brunei and includes a new species record for Brunei. For the first time all but one Palaquium species found in Brunei now have herbarium specimens collected from Brunei cited. A taxonomic account for the 20 species of Palaquium found in Brunei is provided and includes a genus description, full species descriptions, distribution maps and a key to the species. All herbarium specimens collected from Brunei in the BRUN, E and K herbaria have been added to the PADME Sapotaceae data base and, where possible, these have been georeferenced and images of specimens added. Using the distribution data gathered and literature based information of forest threats in Brunei conservation assessments for all species have been produced using IUCN criteria and categories. Problems associated with the lack of material for some species and limited distribution data is discussed as is the importance of taxonomic expertise and clean distribution data for accurate and full species descriptions and conservation assessments. iii Acknowledgements I would like to thank my supervisor Peter Wilkie, for your guidance, patience, and your infectious enthusiasm for the subject. I am grateful to Dr Rahayu Sukri and Mr Joffre Haji Ali Ahmad for allowing me to visit the Brunei National Herbarium to see the Sapotaceae collection. -
PROGRAMME 11 to 15 July 2016 Royal Botanic Garden Edinburgh CLASSIFY CULTIVATE CONSERVE WELCOME MESSAGE
SYMPOSIUM PROGRAMME 11 to 15 July 2016 Royal Botanic Garden Edinburgh CLASSIFY CULTIVATE CONSERVE WELCOME MESSAGE On behalf of the organising committee it is my great pleasure to welcome you to Edinburgh, the Royal Botanic Garden Edinburgh and the 10th International Flora Malesiana Symposium. This year’s symposium brings together taxonomists, horticulturists and conservationists from across the world to discuss their research and conservation activities on the plant diversity of the Malesian region. The theme of this year’s symposium is ‘Classify, Cultivate, Conserve’. At the heart of the symposium is the taxonomic research which underpins all biodiversity research, in particular publications that document and help us better understand the massive diversity of the region. In this symposium we also want to highlight and celebrate the role that horticulture has had in helping us understand this diversity and how it contributes to conservation actions. We hope that by bringing taxonomists, horticulturists and conservationists together in a single symposium, we will better understand the needs of each other and how to be more efficient and effective in helping describe and protect the plant diversity of the region. The symposium is about bringing people together who are passionate about Malesian plants, and about inspiring them to go forward to develop and deliver new and exciting research and conservation projects. It is also about meeting old friends and making new ones. We hope that the scientific and social programme we have put together will encourage you to do both. Finally I would like to thank the Directors of the Royal Botanic Garden for supporting the symposium, the organising committee for their hard work over the past 6 months for making the symposium possible and all delegates for submitting a great range of talks and posters, which we are sure will make for a fantastic symposium. -

Stand Profile Topography of a Primary Hill Dipterocarp Forest in Peninsular Malaysia
Journal of Tropical Forest Science 29(2): 137–150 (2017) Saiful I & Latiff A STAND PROFILE TOPOGRAPHY OF A PRIMARY HILL DIPTEROCARP FOREST IN PENINSULAR MALAYSIA I Saiful* & A Latiff 1Department of Botany, Faculty of Science and Technology, Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor Darul Ehsan, Malaysia *[email protected] Submitted November 2015; accepted November 2016 A stratified systematic sampling along the gradient directed transect was conducted in a primary hill dipterocarp forest in Ulu Muda Forest Reserve, Kedah, Peninsular Malaysia to study the variations of forest profiles in relation to topography. The structural variations are presented in 14 profile diagrams. Forest profiles showed 2–3 tree-canopy layers, depicting the mosaic of structural phases. The most distinguishing structural variation among the profiles was the higher canopy on gently sloping ridgetops with comparatively dense middle storey and scattered emergent trees. Another structural variation was the low stature of the forest on hillsides, with main canopy heights averaging to 22.8 m. Ridgetop profiles were generally vertically continuous, whereas on hillsides there were vertical discontinuities, mainly due to tree fall gaps. Structural pattern described in other studies elsewhere did not match the profiles of the study site, possibly due to the fact that previously published forest profiles were on level ground. As it appeared in the profiles of the study site, the presence of rare species is a contribution to the maintenance of forest structure. Thus the conservation of rare species should be a concern for the management. Keywords: Forest profiles, emergent, canopy layer, understory, tree fall gap INTRODUCTION Natural forests in Malaysia are estimated to Literature shows a dearth of knowledge and cover 19.26 million ha (58.6% of the total information on the basic ecology and silviculture land area) (Anonymous 1992). -
