Kawasan Kaki Gunung Leuser Kedah berbatasan dengan lahan masyarakat, rentan mengalami alih fungsi lahan dan pemburuan liar sehingga menyebabkan keberadaan populasi dan habitat siamang tertekan. Tujuan penelitian ini adalah untuk mengetahui karakteristik habitat siamang (Symphalangus syndactylus Raffles, 1841) dan jenis pohon menjadi habitat siamang. Jenis penelitian ini adalah kualitatif dengan metode survey eksploratif, yaitu menjelajah lokasi-lokasi yang menjadi habitat habitat siamang. Hasil penelitian menunjukkan bahwa Siamang memilih habitat dengan kriteria (a) jumlah sarang 1,65 batang/plot; (b) jumlah pohon pakan 0,85 batang/plot; (c) ketinggian pohon 22,5 meter; (d) ketinggian sarang 17,8 meter; (e) suhu udara 18,50C, (f) kelembaban udara 70,85%; (g) rata-rata penutupan tajuk adalah 87,85%, (h) ketersediaan tempat bergantung 8,75 batang/plot, (i) kemiringan lahan 14,750 dan jarak antar konopi pohon 86,84%. Jenis tumbuhan bersarang siamang diperoleh 45 jenis, 22 suku dan 328 individu. Ketersediaan pohon pakan, tempat bergantung, penutupan tajuk dan suhu udara seimbang. Kesimpulan penelitian ini adalah karakteristik habitat bersarang siamang dengan tinggi rata-rata 17,8 meter, ditemukan hampir setiap plot, suhu dan kelembaban udara optimum, penutupan tajuk 87,85, tempat bergantung terbilang optimum karena jarak antar kanopi sangat dekat, kemiringan lahan rata-rata 14,750.

The foot of Mount Leuser Kedah area is bordered by community land, vulnerable to land conversion and poaching which causes the existence of gibbon populations and habitat to be depressed. The purpose of this study was to determine the habitat characteristics of the gibbons (Symphalangus syndactylus Raffles, 1841) and the types of trees that make them gibbon habitat. This type of research is qualitative with an exploratory survey method, namely exploring locations that are the habitat of gibbons. The results showed that Siamang chose habitat with criteria (a) number of nests of 1.65 stems/plot; (b) number of forage trees 0.85 stems/plot; (c) the height of the tree is 22.5 meters; (d) nest height of 17.8 meters; (e) air temperature 18.50C, (f) air humidity 70.85%; (g) the average canopy cover was 87.85%, (h) the availability of dependent sites was 8.75 stems/plot, (i) the slope of the land was 14.750 and the distance between tree crowns was 86.84%. Types of gibbon nesting plants obtained 45 species, 22 families and 328 individuals. Availability of forage trees, hanging places, canopy closure and air temperature are balanced. The conclusions of this study are the characteristics of gibbon nesting habitat with an average height of 17.8 meters, found in almost every plot, optimum temperature and humidity, canopy closure of 87.85, optimal hanging places because the distance between the canopies is very close, the average slope of the land average 14,750.
