Abstract

Leucopsar rothschildi (Jalak Bali) is an endemic bird species that only be found in the forests of the western of Bali Island. Wild catching and declining forest are the main factors of the declining population. The National Park of West Bali is the last bastion. The habit of living for activity and nesting in the trees make the importance of tree stand to be preserved. Therefore, this study was conducted to analyze the utilizations characteristics of trees by the birds in their original habitat in SPTN III West Bali National Park. The method used was concentration count to observe the characteristics utilization of trees and canopy. Behavior in their natural habitat was observed using Ad Libitum method. Data analysis was conducted by calculating percentage in each part of the usage of canopy and behavior type. The use of the canopy of trees in SPTN III of Labuhan Lalang TNBB by the birds for Tanjung Gelap was more frequent in the upper canopy (TA) section, in Labuhan Lalang more often in the middle canopy (TT) and the middle side canopy (TTt). Frequently activity in the canopy of SPTN III Labuhan Lalang by the birds was social activity.

Abstract

The land use in Argopuro Mountain is very diverse but not much information on the existence of wildlife, especially bird species that important role in helping the regeneration of natural forests and has not been documented its existence. The purpose of this study to determine the diversity of bird species in some land use around the area of Mount Argopuro. Data collection of species and number of birds using stratified systematic sampling with point counts method on each land use planted forest, protected forest, mountain rainforest, savanna and pine forest in the area of Argopura Mountain. Data analysis was done to calculating the diversity index of Shannon bird species. Medium index diversity of bird species was found in planted forest (2.6) and protected forest (2.48); the lowest in the pine forest (1.64), the mountains rainforest (1.96) and savanna (0.68).

Abstract

Keberadaan hutan lindung yang tersisa di kawasan Malang Selatan sangat rentan akan kerusakan habitat satwa liar akibat tingginya aktivitas manusia. Keberadaan kukang Jawa (Nycticebus javanicus) saat ini mampu bertahan hidup pada kawasan yang dikeliling oleh aktivitas manusia yang tinggi. Oleh karena itu, pengaruh aktivitas manusia terhadap keberadaan kukang Jawa yang ada di hutan lindung RPH Sumbermanjing Kulon, Jawa Timur perlu diketahui. Pengambilan data titik keberadaan individu kukang Jawa dilakukan secara langsung dan tidak langsung. Wawancara dengan masyarakat dan pencatatan bentuk aktivitas manusia di sekitar hutan lindung RPH Sumbermanjing Kulon, Jawa Timur juga dilakukan untuk mengambil data. Analisis data dilakukan dengan mengukur jarak antara keberadaan kukang Jawa dengan keberadaan aktivitas masyarakat menggunakan program ArcGis 10.3. Berdasarkan perjumpaan langsung dan informasi dari masyarakat ditemukan enam individu kukang Jawa. Kukang Jawa cenderung ditemukanjauh dari pemukiman dan jalan setapak, namun ditemukan dekat dengan jalan utama dan wisata pantai yang berada di sekitar hutan lindung. Oleh karena itu, keutuhan kawasan hutan lindung perlu tetap dijaga dari segala bentuk aktivitas manusia yang tinggi.
