Daftar Isi:
- The downstream area of Unda River Watershed located in Klungkung Regency has experienced succession due to the eruption of Mount Agung in 1963. The ecosystem in the downstream area of the Unda River also experienced anthropogenic succession due to human activities which affected the plant species that composing the vegetation. This study aims to observe the floristic composition of vegetation in the downstream area of the Unda River. The research was conducted by exploration method in three types of ecosystems: lowland forest, marshes, and beaches. The results show the floristic composition in the downstream of Unda River composed by 163 plant species, classified in 48 families and 128 genera. The major growth form is small herb (47 species), grass (35 species), and tree (31 species). Fabaceae is the plant family with the most abundant species, followed by Poaceae and Cyperaceae. Based on the research zones, the lowland forest has the highest number of plant species (120 species), while the beach zone has the lowest (82 species). The ecosystem stability in the downstream area of Unda River can be disturbed by the existence of invasive species, such as Eichhornia crassipes, Chromolaena odorata, Lantana camara, Ipomoea carnea, Vachellia farnesiana, and Typha angustifolia.
- Kawasan hilir Daerah Aliran Sungai (DAS) Unda yang terletak di Kabupaten Klungkung telah mengalami suksesi akibat letusan Gunung Agung pada tahun 1963. Ekosistem di kawasan hilir Sungai Unda juga mengalami suksesi antropogenik akibat aktivitas manusia. Proses suksesi tersebut berdampak terhadap spesies tumbuhan penyusun vegetasi di kawasan tersebut. Penelitian ini bertujuan untuk mempelajari komposisi floristik vegetasi di kawasan hilir Sungai Unda. Penelitian dilakukan dengan metode jelajah pada tiga tipe ekosistem, yaitu ekosistem hutan dataran rendah, lahan tergenang, dan pantai. Hasil penelitian menunjukkan bahwa komposisi floristik di kawasan hilir Sungai Unda terdiri dari 163 jenis tumbuhan yang terbagi ke dalam 48 suku dan 128 marga. Bentuk hidup spesies tumbuhan didominasi oleh herba kecil (47 spesies), rumput (35 spesies), dan pohon (31 spesies). Fabaceae adalah suku dengan jumlah spesies terbanyak, diikuti oleh suku Poaceae dan Cyperaceae. Berdasarkan zona penelitian, hutan dataran rendah memiliki jumlah spesies terbanyak (120 spesies), sedangkan zona pantai paling sedikit (82 spesies). Stabilitas ekosistem di Kawasan Sungai Unda dapat terganggu oleh beberapa spesies tumbuhan invasif seperti eceng gondok (Eichhornia crassipes), kirinyuh (Chromolaena odorata), tembelekan (Lantana camara), kangkung pagar (Ipomoea carnea), akasia duri (Vachellia farnesiana), dan ekor kucing (Typha angustifolia).
