ABSTRAKTelah dilakukan penelitian mengenai lumut epifit di dua lokasi berbeda di
Universitas Indonesia (UI). Penelitian bertujuan untuk membandingkan
keragaman lumut epifit di hutan kota dan tepi jalan utama kampus. Terdapat 12
plot berukuran 25 x 25 m2 yang tersebar di hutan kota, sedangkan pada tepi jalan
utama kampus tersebar 9 transek garis sepanjang 50 m. Pada setiap plot dan
transek diambil 5 individu pohon sebagai sampel pohon inang. Subplot berukuran
15 x 15 cm2 yang berjumlah 8 subplot ditempatkan pada pada setiap pangkal
batang sampel pohon inang (0--200 cm). Hasil yang diperoleh menunjukkan
bahwa terdapat 23 spesies lumut epifit yang terdiri atas 21 spesies di hutan kota
dan 14 spesies ditemukan di tepi jalan utama kampus. Kesamaan komunitas
lumut epifit antara hutan kota dan tepi jalan utama kampus termasuk kategori
tinggi (Indeks kesamaan Sorenson = 0,73). Octoblepharum albidum merupakan
spesies dominan di hutan kota, sedangkan Calymperes tenerum dominan pada tepi
jalan utama kampus. Keragaman lumut epifit pada kedua lokasi tersebut tidak
berbeda signifikan dan termasuk kategori rendah berdasarkan indeks keragaman
Shanon Wiener (H?< 2).
AbstractResearch on epiphytic bryophytes has been conducted in two different
sites located in Universitas Indonesia (UI). Those sites were urban forest and
vegetation on main street margin of the campus. This study was carried out to
compare diversity of the bryophyte at both sites. Twelve plots of 25 x 25 m2 were
establish at the forest, while nine of 50 m line transect were made at the street
margin. Five trees of each plot or line transect were sampled. Eight sub plots of
15 x 15 cm2 were placed on each trunk base (0--200 cm) of the tree sampels. The
results obtained 23 species of epiphytic bryophytes, 21 species occured in the
forest and 14 species were found at street margin. The similarity of bryophyte
community between the forest and street margin based on Sorenson Similarity
were high (0.73). Octoblepharum albidum was the dominant species at the forest,
while Calymperes tenerum was dominant at the street margin. The diversity of
epiphyte bryophyte at both sites were categorized low based on Shannon Wiener
index (H?< 2), however there was not significantly different between those place.
