Abstract

Historically, and based on the latest conditions, Samboja Research Forest has a fairly high vulnerability to the presence of invasive species that can interfere with ecosystem stability and forest succession. However, data collection and risk assessment of invasive species have not been conducted in the forest area. T h e study was c arried out t o support the management of Samboja Research Forest , particularly in controlling invasive species. The study was conducted with exploration techniques in open areas , secondary forests , and primary forests . T he density and frequency data of invasive plants we re obtained using random plots in secondary and primary forest areas. The results showed the presence of 52 invasive plant species in the Samboja Research Forest area with dominance by shrubs and herbs. B ased on plants distribution and density , four crucial invasive plant species in Samboja Research Forest were identified , namely: Acacia mangium, Spathodea campanulata, Miconia crenata , and Piper aduncum. The management of invasive species wa s carried out in two stages, short term, through manual weeding, and in the long term, with the prevention, eradication, and periodic risk assessment. Keywords: invasive alien species, Kalimantan, eradication, Spathodea campanulata

从历史上看，基于最新的条件，Samboja研究林对入侵物种的存在具有相当高的脆弱性，这些入侵物种会干扰生态系统的稳定性和森林的演替。然而，目前尚未开展林区入侵物种的数据收集和风险评估。这项研究是为了支持Samboja研究林的管理，特别是在控制入侵物种方面。本研究采用勘探技术在开阔地区、次生林和原始林进行。在次生林和原生林的随机样地获取入侵植物的密度和频率数据。结果表明，三宝加研究林区共有52种外来入侵植物，以灌木和草本植物为主。根据植物的分布和密度，确定了三宝加研究林的4种重要入侵植物，分别是:相思(Acacia mangium)、鸡血花(spthodea campanulata)、绿毛鼠(Miconia crenata)和灰椒(Piper aduncum)。入侵物种的管理分两个阶段进行，短期通过人工除草，长期通过预防、根除和定期风险评估。关键词:外来入侵物种;加里曼丹;根除

期刊介绍： The Journal of Symbolic Logic publishes research in mathematical logic and its applications of the highest quality. Papers are expected to exhibit innovation and not merely be minor variations on established work. They should also be of interest to a broad audience. JSL has been, since its establishment in 1936, the leading journal in the world devoted to mathematical logic. Its prestige derives from its longevity and from the standard of submissions -- which, combined with the standards of reviewing, all contribute to the fact that it receives more citations than any other journal in logic.
