Ketiga tipe tersebut karakteristik yang ditunjukkan oleh struktur komposisi spesies tumbuhan berbeda. Meskipun demikian, kajian terhadap berbeda di suatu lingkup area masih sangat terbatas. Penelitian ini bertujuan untuk membandingkan komunitas pada menggunakan metode plot dilanjutkan dengan analisis vegetasi. Berdasarkan hasil vegetasi, hutan pohon terbanyak (16 spesies). Pada bentuk pertumbuhan tiang, kopi riparian sama-sama 13 spesies. Untuk pancang, Jenis INP (Indeks Nilai Penting) tertinggi adalah Tabernaemontana sphaerocarpa (48,31%) pohon, Polyscias nodosa (80,34%) Areca triandra (129,66%) pancang. perkebunan, Magnolia champaca (85,33%) Leucaena leucocephala (74,61%) Coffea arabica (166,30%) riparian, Swietenia mahagoni (79,51%) tiang (68,45%), serta Gliricidia sepium pancang (40,93%). Indeks Keanekaragaman, ketiga nilai rentang 1-3 termasuk dalam keanekaragaman sedang. Dominasi < 0,5 menunjukkan tidak ada dominasi jenis, Keseragaman > sebaran jenis merata.
