Keanekaragaman dan Pola Sebaran Spesies Tumbuhan Asing Invasif di Resort Andongrejo Taman Nasional Meru Betiri

Abstract

Spesies tumbuhan asing invasif (IAS) merupakan spesies tumbuhan yang tumbuh baik secara liar ataupun hasil introduksi di luar habitat alaminya yang keberadaannya dapat mengganggu spesies lokal. Introduksi spesies asing invasif di zona rehabilitasi dan penyebaran spesies yang tumbuh secara liar di Taman Nasional Meru Betiri berpotensi invasif. Penelitian ini bertujuan untuk mengidentifikasi komposisi vegetasi, keanekaragaman spesies tumbuhan asing invasif, dan pola sebaran tumbuhan asing invasif di Resort Andongrejo Taman Nasional Meru Betiri. Metode pengumpulan data yang dilakukan yaitu dengan analisis vegetasi, observasi lapang, dan studi literatur yang kemudian dianalisis secara kuantitatif. Berdasarkan hasil analisis spesies tumbuhan asing invasif yang terdapat di Resort Andongrejo teridentifikasi sebanyak 24 spesies memiliki pola sebaran mengelompok diantaranya pada zona rehabilitasi teridentifikasi 24 spesies dan zona rimba teridentifikasi 9 spesies dengan dominansi tertinggi pada spesies Chromolaena odorata dan Mikania micrantha.

Invasive alien species (IAS) are plant species that grow either wild or introduced outside their natural habitat and whose presence can disturb local species. The introduction of invasive alien species in the rehabilitation zone of Meru Betiri National Park has the potential to be invasive. This research aims to do identify the composition of vegetation, the diversity of invasive alien species (IAS), and the distribution patterns of IAS at the Andongrejo Resort, Meru Betiri National Park. The data collection method used was vegetation analysis, field observation, and literature study which was then analyzed quantitatively. Based on the results of the analysis of IAS found at the Andongrejo Resort, 24 species were identified that had a clumped distribution pattern, including in the rehabilitation zone 24 species were identified and 9 species were identified in the jungle zone with the highest dominance being the species Chromolaena odorata and Mikania micrantha.
