Tumbuhan asing invasif merupakan salah satu ancaman bagi keanekaragaman hayati Indonesia. Tumbuhan ini dapat mengubah ekosistem dengan mendominasi lanskap. Mengingat besarnya dampak yang dapat ditimbulkan oleh invasi tumbuhan di kawasan konservasi, maka perlu dilakukan inventarisasi jenis-jenis tumbuhan yang berpotensi invasif di Taman Nasional Way Kambas (TNWK), sehingga dampak negatif dari invasi akan mudah di cegah. Inventarisasi dilakukan dengan membuat plot analisis vegetasi pada empat tipe vegetasi di TNWK, yaitu vegetasi hutan, vegetasi hutan campuran, vegetasi rawa dan vegetasi alang-alang. Berdasarkan hasil analisis vegetasi, diperoleh 11 jenis tumbuhan berpotensi invasif di TNWK, yaitu Actinoscirpus grossus, Clidemia hirta, Chromolaena odorata, Fimbristylis ovata, Hyptis capitata, Imperata cylindrica, Isachne globosa, Lantana camara, Melaleuca leucadendron, Melastoma malabathricum, dan Mimosa pigra. Invasive alien plant species are a threat to Indonesia's biodiversity. These plants can change ecosystems by dominating landscapes. Given the magnitude of the impact that can be caused by plant invasions in conservation areas, it is necessary to carry out an inventory of potentially invasive plant species in Way Kambas National Park (TNWK), so that the negative impacts of these invasions can be easily prevented. . The inventory was carried out by plotting vegetation analysis on four types of vegetation in TNWK, namely forest vegetation, mixed forest vegetation, swamp vegetation, and alang-alang vegetation. Based on the results of the vegetation analysis, 11 species of plants that have the potential to be invasive in TNWK were found, namely Actinoscirpus grossus, Clidemia hirta, Chromolaena odorata, Fimbristylis ovata, Hyptis capitata, Imperata cylindrica, Isachne globosa, Lantana camara, Melaleuca leucadendron, Melastoma malabathricum, dan Mimosa pigra.
