Penelitian ini bertujuan untuk menginventarisasi jenis-jenis reptil serta menganalisis tingkat keanekaragaman, kekayaan, dan kemerataan spesies pada tiga tipe habitat berbeda di Stasiun Penelitian Suaq Belimbing, Kabupaten Aceh Selatan. Survei dilakukan menggunakan metode Visual Encounter Survey (VES) dan jalur transek yang tersebar di habitat riparian, rawa, dan bukit. Parameter lingkungan biofisik seperti suhu udara, suhu permukaan, kelembapan, dan ketinggian turut dicatat sebagai variabel ekologis pendukung. Hasil penelitian mencatat 29 jenis reptil dari 11 famili. Habitat riparian menunjukkan indeks keanekaragaman tertinggi (H’ = 2,69), diikuti habitat bukit (H’ = 2,48), dan habitat rawa (H’ = 2,28). Selain itu, indeks kekayaan dan kemerataan juga bervariasi antartipe habitat. Faktor lingkungan seperti kelembapan tinggi dan suhu yang stabil secara signifikan memengaruhi distribusi dan aktivitas spesies. Temuan ini menunjukkan bahwa kawasan SP. Suaq Belimbing memiliki kualitas ekologis yang baik dan berfungsi sebagai habitat penting bagi keanekaragaman reptil. Data yang diperoleh diharapkan menjadi dasar bagi upaya konservasi dan pengelolaan keanekaragaman hayati secara berkelanjutan.

This study aimed to inventory reptile species and analyze their diversity, richness, and evenness across three different habitat types at the Suaq Belimbing Research Station, South Aceh Regency. The survey employed Visual Encounter Survey (VES) methods combined with line transects distributed in riparian, swamp, and hill habitats. Biophysical environmental parameters such as air temperature, surface temperature, humidity, and elevation were recorded as supporting ecological variables. A total of 29 reptile species from 11 families were documented. The riparian habitat showed the highest diversity index (H’ = 2.69), followed by the hill habitat (H’ = 2.48), and the swamp habitat (H’ = 2.28). Species richness and evenness also varied across habitats. Environmental factors such as high humidity and stable temperature significantly influenced species distribution and activity. These findings indicate that the Suaq Belimbing area maintains high ecological quality and serves as a crucial habitat for reptile biodiversity. The data generated is expected to serve as a foundation for conservation efforts and sustainable biodiversity management.
