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.

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).

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.

R. zollingeriana Kds. di Indonesia dapat ditemui di Taman Nasional Meru Betiri, Jawa Timur yang memang memiliki keanekaragaman vegetasi yang melimpah. Penelitian ini bertujuan untuk mengidentfikasi persebaran dan habitat R. zollingeriana Kds., serta asosiasi antara R. zollingeriana Kds. dengan spesies lain yang ada di plot permanen Blok Krecek Resort Bandealit Taman Nasional Meru Betiri. Persebaran dan habitat R. zollingeriana Kds. dikaji melalui analisis vegetasi dengan menghitung Indeks Nilai Penting (INP), Indeks Kesamaan, Indeks Keragaman, Indeks Kekayaan, dan Indeks Kemerataan, serta melakukan analisis terhadap kondisi abiotik yang meliputi jenis tanah, kelembaban tanah, kelerengan, ketebalan seresah, dan pH tanah. Asosiasi antara R. zollingeriana Kds. dengan spesies lain dikaji melalui analisis kontingensi, uji chi square (x2), dan uji tingkat kekuatan asosiasi. Tercatat sebanyak 4 individu R. zollingeriana Kds. yang mengelompok pada plot 1.

Areas with natural forest potential that are still preserved have the potential to birdwatching activities, a concept of sustainable tourism to preserve the environment and increase the participation of local communities. Protected forests in the South Malang area are natural forests which are still protected by habitat conditions for wild animals, especially for bird species. The purpose of this study was to determine the potential development of a birdwatching track based on the distribution of birds in the Protected Forest Area of Sumbermanjing Kulon KPH Malang. Make a path of observation and identify the types of birds found in protected forests. Knowing the community's response to birdwatching activities around protected forests through interviews. Data analysis was done by making a map of the distribution of maps and the potential of the observation pathway using the ArcGis 10.3 program. There are 51 species of birds with 3.4 species diversity (H ') in the high category. The potential of 22 birdwatching routes with mostly flat road conditions (59%), sloping (23%) and steep (18%). Bird species that can be found in 6 species of birds for each observation pathway. Knowledge of respondents related to the ability to recognize 3-5 species of birds 40%, recognize 70% birdwatching activities, and 83% of respondents' agree with the development of birdwatching as a tourism.

IUPHHK-RE PT Ekosistem Khatulistiwa Lestari is the habitat of various wildlife species, comprises of a restoration forest area surrounded by production forest and oil palm plantations. The threats of damages from illegal logging and land clearing activities tend to threaten the wildlife existence. Therefore, this study aims to determine the distribution and diversity of bird species in PT Ekosistem Khatulistiwa Lestari. The study was conducted from January - February 2019, and data collection was conducted using the IPA (Index Ponctualle deAbondance) method. Furthermore, data analysis used diversity index, evenness index, and species similarity with dendrogram analysis using SPSS 21. The results showed that the highest bird species were found in mangroves (32 species), old swamp scrubs (26 species), young swamp scrubs (24 species), plantations (13 species), and settlement (15 species) habitats. Meanwhile, the diversity index of bird species in the five habitat types is classified as medium diversity. Species evenness with the highest value is settlement (E = 0.93). The dendrogram image of the settlement area showed bird species, which can be found in the other four habitats. Keywords: diversity, bird distribution, West Borneo, dendrogram

The Protected Forest of RPH (Forest Management Resort) Sumbermanjing Kulon is an area, which is susceptible to land conversion due to human activities, such as road construction and tourism. These conditions might harm the habitat of several animals and disturb their movements, specifically in the mammal group. Therefore, the purpose of this research is to determine the distribution and diversity of mammals as the basis for the proper management of the RPH. This research was conducted on a variety of forest habitats located on plot 97A, which covers an area of 331.5 Ha. Moreover, data were collected by creating line transects in this location and then analyzed by constructing a map of the mammals' distribution using the Shannon-Winer diversity index, evenness, and species richness. According to the results, 23 species of mammals were scattered in three types of habitats. The low category of mammal species diversity index was discovered in the mangrove forest (0.69), while the tropical rainforest (2.48) and coastal forest (2.18 were moderate). Furthermore, the mammal species evenness index in the lowland tropical rainforest, mangrove, and coastal forests indicated relatively even results while the highest mammal species richness index was detected in the lowland tropical rainforest. The mammal diversity results can be used by area managers for sustainable management.
