ABSTRACT
A brief study of the amphibian fauna of Bubu Permanent Forest Reserve, Perak, which constitutes the southernmost part of the Bintang Hijau Forest Reserve, was carried out from 18 to 21 December 2006 to determine the diversity and density estimate of amphibian species in the area. Field parties comprising seven persons searched and collected amphibians froma small stream, the Dal River, in Compartments 6 and 7 of the Bubu Permanent Forest Reserve, from 2000 hrs to 2300 hrs for three consecutive nights. A total of 79 individual frogs from 13 species in five families were recorded. The five most abundant species were Hyalrana nicobariensis, H. labialis, Pedostibes hosii, Phrynoides aspera and Amolops larutensis. Six other species were considered rare, namely Limnonectes doriae, H. picturata, Odorrana hosii, Polypedates leucomystax and Rhacophorus bimaculatus. Preliminary analysis of the data showed that the estimated populations of H. nicobariensis, H. labialis and P. hosii are 23, 13 and 10 individuals per 100 meters of river length, respectively. Due to the brief nature of the study, and the small area covered, the number of species is considered relatively moderate. More than 95% of frogs collected are forest species that require clean and pollution-free habitats to survive. This shows that the Dal River is apristine river flowing from the Gunung Bubu range. It originated from a virgin jungle, hence it has clear waters with a minimum amount of pollution and disturbance. We hope that the relevant authorities will preserve it as it is for the benefit of future generations and more importantly, for the continued survival of the amphibian fauna.
ABSTRAK
Satu kajian ringkas tentang fauna amfibia di Hutan Simpan Kekal Bubu, Perak, iaitu bahagian yang paling selatan daripada Hutan Simpan Bintang Hijau, telah dijalankan dari 18 hingga 21 Disember 2006, untuk menentukan kepelbagaian dan anggaran populasi spesies amfibia di situ. Kumpulan pencari yang terdiri daripada tujuh orang telah mencari dan memungut haiwan amfibia daripada sebuah sungai kecil, Sungai Dal, di dalam Kompartmen 6 dan 7 Hutan Simpan Kekal Bubu, dari jam 2000 hingga jam 2300 untuk selama tiga malam berturut-turut. Sejumlah 79 individu katak dari 13 spesies dalam lima famili telah direkodkan. Lima spesies katak yang paling limpah ialah Hyalrana nicobariensis, H. labialis, Pedostibes hosii, Phrynoides aspera dan Amolops larutensis. Enam spesies lain adalah dianggap jarang ditemui iaitu Limnonectes doriae, H. picturata, Odorrana hosii, Polypedates leucomystax dan Rhacophorus bimaculatus. Analisis awal data menunjukkan bahawa anggaran kepadatan untuk H. nicobariensis, H. labialis dan P. hosii adalah masing-masing 23, 13 dan 10 individu per 100 meter panjang sungai. Disebabkan oleh kajian ini ringkas dan kawasan kajian yang kecil, bilangan spesies adalah sederhana. Lebih daripada 95% katak yang ditangkap adalah spesies hutan yang memerlukan habitat tidak tercemar untuk hidup. Ini membuktikan bahawa Sungai Dal adalah sungai yang berpunca dari hutan dara Gunung Bubu, di mana air nyatidak tercemar atau terganggu. Diharapkan agar pihak berwajib dapat memeliharakan kawasan ini untuk kepentingan genarasi akan datang dan lebih lagi untuk kemandirian fauna amfibia di situ.
