Association Of Shorea Platyclados With Dominant Trees In Martelu Purba Nature Reserve

Abstract

Shorea platyclados, known to the public as Meranti Bukit, is one of the species whose existence S. platyclados Slooten ex Foxw. or what is known by the local name Meranti Bukit is a type of meranti tree that has fast growth and is recommended as a plant for forest and land rehabilitation activities. S. platyclados is threatened in nature and is included in the Near Threatened (NT) its category based on the IUCN Redlist. Conservation efforts are needed to better understand natural habitat conditions and increase the population of S. platyclados in nature with an ecological approach. An association is a common kind of community that is present in many places and occurs under similar circumstances.. Associations are characterized by having a similar floristic composition, having a uniform physiognomy, and their distribution having a unique habitat. Studies on plant associations around S. platyclados have yet to be revealed so a more in-depth ecological analysis is needed to determine the relationship between S. platyclados and other plants around it. The purpose of this study was to analyze the association between S. platyclados and the dominant trees in the Martelu Purba Nature Reserve area. Using the 2x2 Contingency Table, association analysis was performed on the primary constituent species with an IVI of ≥10%.. The results of the analysis of the type of association between S.platyclados and the dominant tree showed positive for Charcoal and Akhirsap species, while for Modang, Beringin, and Kemenyan species negative association.
