Diversity of Bird Species in the Oil Palm Plantation on Peat
Bettycopa Amit*, Andrew Alek Tuen**, Khalid Haron* and Mohd Haniff Harun*Oil palm plantation on peat creates an alternative habitat for birds to live in. In order to find out the diversity of bird species dwelling in this oil palm habitat, surveys were carried out in a seven-year old oil palm plantation established on peat soil near Betong, Sarawak between August 2010 to October 2011. The survey was done by observation and mist netting methods. A total of 463 individual birds belonging to 42 species were recorded and this represents approximately 7% of the total species known to occur in Borneo. More than 50% of the birds recorded in oil palm plantation are feeding on insects. Besides that, wetland birds and birds of prey were also recorded in this habitat. Among the 42 species sampled, Yellow-vented Bulbul (23.3%) was the most dominant species. Twenty-six percent of the birds recorded in oil palm plantation are categorised as protected birds under the Sarawak Wild Life Protection Ordinance (1998). Our results suggest that the seven-year old oil palm plantation in Betong, Sarawak had a reasonably good community of birds. More sampling works are needed in order to study the population gradient over time to gain a better understanding on bird response to dynamic change.
Ladang sawit di paya gambut mewujudkan habitat alternatif kepada burung untuk didiami. Dalam usaha untuk mengetahui kepelbagaian spesies burung yang tinggal di habitat ini, kaji selidik telah dijalankan antara Ogos 2010 hingga Oktober 2011 di ladang sawit berusia tujuh tahun yang terletak di kawasan paya gambut, Betong, Sarawak. Kajian ini dijalankan dengan menggunakan kaedah pemerhatian dan jaring samar. Sebanyak 463 individu dari 42 spesies burung telah direkodkan dan ini mewakili lebih kurang 7% daripada jumlah spesies yang telah direkodkan di Borneo. Lebih daripada 50% burung di ladang sawit yang makan serangga. Selain itu, burung tanah paya dan burung pemangsa juga telah direkodkan di habitat ini. Di antara 42 spesies burung ini, Merbah Kapur (23.3%) adalah spesies yang paling dominan di habitat ini. Dua puluh enam peratus daripada burung di ladang sawit dikategorikan sebagai burung yang dilindungi di bawah Ordinan Perlindungan Hidupan Liar Sarawak (1998). Keputusan ini menunjukkan bahawa ladang sawit berusia tujuh tahun di Betong, Sarawak, mempunyai komuniti kepelbagaian spesies burung yang baik. Kajian yang lebih mendalam amatlah diperlukan untuk mengkaji kecerunan populasi burung dari semasa ke semasa untuk mendapatkan pemahaman yang lebih baik mengenai tindak balas burung terhadap perubahan dinamik ini.
