BAB VI KESIMPULAN DAN SARAN
6.1 Kesimpulan
1. Spesies tumbuhan asing invasif di Cagar Alam Kamojang teridentifikasi
sebanyak 13 spesies dari 8 famili yaitu Ageratum conyzoides Asteraceae, Rubus moluccanus Rosaceae, Clidemia hirta Melastomaceae, Cynodon
dactylon Poaceae, Panicum repens Poaceae, Mimosa pudica Fabaceae, Mimosa pigra Fabaceae, Austroeupatorium inulifolium
Asteraceae, Passiflora edulis Passifloraceae, Lantana camara Verbenaceae, Mikania micrantha Asteraceae, Piper aduncum
Piperaceae dan Ageratina riparia Asteraceae. Berdasarkan indeks nilai pentingnya, spesies tumbuhan invasif yang mendominasi di Cagar Alam
Kamojang terdiri dari A. inulifolium 67,37, A. riparia 46,15 dan L. camara 15,37.
2. Pola sebaran spasial spesies tumbuhan asing invasif berdasarkan indeks
Morisita dan hasil interpolasi IDW cenderung mengelompok pada kondisi kawasan yang relatif terbuka kecuali untuk spesies A. inulifolium yang
menyebar secara merata di Cagar Alam Kamojang. 3.
Faktor jarak dari jalan hanya mempengaruhi sebaran jumlah individu A. inulifolium dengan model persamaan y = 20,911 + 0,055x, sedangkan
faktor jarak dari jalan tidak mempengaruhi sebaran jumlah individu spesies A. riparia dan L. camara di Cagar Alam Kamojang.
6.2 Saran
1. Perlu dilakukan upaya pengendalian secara manual terhadap spesies
tumbuhan asing invasif terutama spesies A. inulifolium, A. riparia dan L. camara di lokasi yang memiliki permudaan spesies pohon lokal di Cagar
Alam Kamojang. 2.
Perlu dilakukan penelitian lanjutan mengenai distribusi spesies tumbuhan asing invasif berdasarkan ketinggian tempat dan kondisi keterbukaan
lahan.
