Abstract

Research on Rhacophorus barisani (Harvey, Pemberton & Smith, 2002) has been limited since its formal description in 2002. Since 2017, the IUCN has classified the Barisan Tree Frog as Least Concern, and this species is endemic to the mountain forests of the Bukit Barisan Mountains in Sumatra. Published records are limited to distribution notes and photographs, with no previous reports from Karo Regency, North Sumatra. This study was conducted between September and November 2023 in the Bukit Barisan Grand Forest Park (Tahura) and Gunung Sibuatan Protected Forest. The methods used were Visual Encounter Survey-Night Stream (VES-NS) and purposive sampling. This species was described morphologically and morphometrically, and habitat suitability data were recorded based on abiotic parameters. R. barisani was found in flowing water habitats and still water pools within the forest. R. barisani has three distinct dorsal color patterns: a light brown base color with a yellowish-brown color on the back that does not reach the sides of the body; a uniform yellowish-brown base color with yellow edges and a distinct dorsal pattern and black bands on the limbs; a green base color with scattered brown or black protuberances on the back, and a snout-vent length ranging from 41.9 to 65.7 mm. The habitat suitability of this species occupies riparian and lotic areas. Critically, we confirm that this species is the first record in Karo Regency, representing a new local discovery.

Abstract

Rubiaceae is a common forest plant family in Indonesia, including in many community-managed village forests such as the Serdang Village Forest in Barusjahe, Karo, North Sumatra. A thorough inventory of rubiaceous species is needed to understand their composition and usage by local people. This study aims to list all Rubiaceae species, understand their morphological characteristics, and document their utilization in the village forest. The exploration identified 18 species of Rubiaceae from 12 different genera. Nine species are utilized by the local community: four species as traditional medicine, two species as ornamental plants, one species for firewood, and one species for house/garden posts and household tools. This research enhances the understanding of Rubiaceae species and their uses in the Desa Serdang village forest.

Abstract

Background: Universities play a critical role in the development of urban ecosystems, which include artificial forests, parks, and green open spaces. Medan State University is one of the campuses in Medan City, North Sumatra, that boasts a significant amount of green open space. In order to identify and prioritize the conservation of woody plant species, data collection is necessary. Methodology: The method employed exploration, which involves the recording of all woody plants and their presentation in a qualitative descriptive format. Findings: The data on woody plants in the green open spaces of Medan State University are categorized into 2 subdivisions, 48 families, and 146 species, as indicated by the study's findings. Contribution: Protective plants, medicinal plants, spices, fresh fruits, and ornamental plants are all utilized. It is anticipated that the findings of this investigation will serve as a reference for future research on woody plants in urban green open spaces
