We carried out a survey of Nahan’s Partridge Ptilopachus nahani in the Ugandan forests of Mabira, Bugoma, and Budongo from December 2016 to December 2017, using a point count method employing a call playback technique.  The aim was to establish the population status of this globally threatened species, which was last surveyed in 2003.  Separate analyses of the number of groups per point and those involving use of the Distance Program yielded the same density estimates, indicating that either method reliably estimates the density of the species.  The density estimates for the three reserves were 31.6, 25.2, and 13.3 groups per km2 for Bugoma, Budongo, and Mabira forest reserves, respectively.  In the last 14 years, it appears that the density of the species for Uganda has increased from 16.3 to 23.4 groups per km2, which when extrapolated translates to 16,000 and 23,000 groups, respectively.  This represents a 44% increase in density, or a group growth rate of 450 per year.  The lowest density and population increment was registered in Mabira and we attribute this to the apparently high incidence of disturbance and degradation of this forest compared to the other two.  Since Mabira, Bugoma, and Budongo are the only remaining large tropical rainforest reserves in Uganda, strengthening their conservation or upgrading their conservation status to national parks is required to save the species.

Wildlife diversity (amphibians, reptiles, birds and mammals) of Kashimpur Union in Gazipur Sadar Upazila under Gazipur district was studied from May, 2015 to March, 2016. A total of 110 species of wildlife belonging to 58 families under 19 orders were recorded. Among them, 6 (5.45%) species were amphibians, 14 (12.72%) reptiles, 72 (65.45%) birds and 18 (16.38%) were mammals. Among the amphibians, 5 (83.33%) species were frogs and only one (16.67%) was toad; of reptiles, 7 (50%) species were lizards, 5 (35.71%) snakes and 2 (14.29%) were tortoises. Of the birds, 39 (54.16%) species were passerines and remaining 33 (45.84%) were non-passerines. Resident status shows that 66 (91.62%) species were resident, 5 (7.00%) migrants and 1 (1.38%) species were vagrant. Among the mammals, 8 (44.45%) species were rodents, 4 (22.22%) flying mammals and 6 (33.33%) species were carnivorous mammals. The relative abundance shows that 10 (9.09%) species were very common, 24 (21.81%) common, 31 (28.19%) fairly common and 45 (40.91%) species were few. Considering the conservation status, 5 species were near threatened and 105 were the least concern nationally. According to Shannon-Wiener (H = 3.287) and Simpson's (D = 0.942) diversity indices, diversity of birds was higher than the other wildlife observed. Some potential threats on wildlife diversity were identified such as habitat degradation and fragmentation, expansion of agricultural lands and urbanization. Therefore, conservation and management are necessary in order to protect the diversity of existing wildlife and their population in the study area. Asiat. Soc.

SummaryThe Hainan Hill-partridge Arborophila ardens is endemic to the island of Hainan, which lies off the south coast of China. Distinct subspecies of the Silver Pheasant Lophura nyethemera xvhiteheadi and Grey Peacock-pheasant Polyplectron bicalcaratum katsumatae are also endemic to the island. All three taxa are considered endangered and are very poorly known in the wild. Surveys of remaining patches of forest were undertaken between 1987 and 1994 during which local people were interviewed and some forest areas were visited. The hill-partridge was confirmed from three blocks of forest and reported from a further four. The Silver Pheasant was found in six areas of forest and probably occurs in all remaining patches of well-developed secondary and primary forest. The Grey Peacock-pheasant was recorded in five forests and reported from a further four. The hill-partridge was more restricted in its habitat use than the other two species, the latter using well-developed secondary forest in addition to primary forests. Provisional density estimates made at Ba Wang Ling National Nature Reserve were 6–8 Hainan Hill-partridges/km2, 7.5 Silver Pheasants/km2 and 3.75 Grey Peacock-pheasants/km2.

Abstract Birds are habitat specialist, i.e. often selects habitat that offers ample services such as a variety of food resources, safe breeding and less disturb sites to satisfy their needs. We aimed to ascertain the conservation status of avian assemblages inhabited in six different coniferous forests. The study employed the point count method to determine the avian assemblages in each forest type. The surveys were conducted employing the distance sampling point count method and determining the floristic composition through direct visual estimation from January 2018 to March 2019. In total, 2465 bird individuals representing 57 species and 29 families were observed in six coniferous forests. Twelve tree species, nine shrub species, and 14 grass species were identified in the forests. Except for the Streptopelia turtur (vulnerable), all bird species are listed as “least concern” according to the IUCN Red List Category and Criteria 2019–2. Notably, the relative abundance of bird assemblages among six coniferous habitats was significantly different (F5, 293 = 22.8, p < 0.05). The CAP results reflected that bird diversity indices varied coniferous forests. Strikingly, dry–temperate coniferous forest (BG) was densely populated (5.831 ± 0.694 birds•ha−1) as compared to other habitats. These findings suggested that subtropical coniferous forests are cradles of life for a wide array of avian assemblages and hence should be declared as protected forests to enhance avian assemblages in this region.

No bryophyte conservation programs are in place in Australia as the knowledge of bryophytes is poor, especially of their habitat preferences and distribution. The conservation of species against habitats is discussed and it is maintained on present evidence that areas conserved for vascular plants and/or animal habitats, as national parks and forest reserves, in most cases would adequately conserve bryophytes.

Point Count Method

The island of Buru in Maluku province, Indonesia was visited in November and December 1989. Using a point count method, we assessed the conservation status of the island's restricted-range lowland birds by examining their abundance and habitat associations. Thirteen of Buru's 19 lowland restricted-range species were recorded during the fieldwork. Of these we assign nine (White-eyed Imperial Pigeon Ducula perspicillata, Moluccan Red Lory Eos bornea, Bum Racquet-tail Prioniturus mada, Black-tipped Monarch Monarcha loricatus, White-naped Monarch Monarcha pileatus, Dark-grey Flycatcher Myiagra galeata, Flame-breasted Flowerpecker Dicaeum erythrothorax, Bum Yellow White-eye Zosterops buruensis and Black-faced Friarbird Philemon moluccensis) to IUCN's Safe/Low risk category of threat, on the basis of their large populations, widespread occurrence on Bum and association with non-pristine habitats. We recommend that the remaining six of the recorded species remain Data-deficient but some of these (e.g. Blue-fronted Lorikeet Charmosyna toxopei and Bum Cuckoo-shrike Coracina fortis) may be Vulnerable. While data on the birds which we did not record are obviously needed, we suggest that the amount of forest remaining, the abundance of many species and their tolerance of selectively logged forests bodes well for the immediate future of the bulk of Buru's lowland avifauna.

AbstractWildlife managers require status and distribution information for informed decisions. Recognizing the tiger's globally threatened status and potential as an umbrella species for protection of forested landscapes, camera trap surveys for tigers and other large mammals have been conducted since 1997 in Peninsular Malaysia with the aim of assessing the population status of tigers in the Peninsula. Results from surveys at nine sites between December 1997 and December 1999 are reported here. Tigers were confirmed from six sites in the Main Range and Greater Taman Negara landscape, with multiple locations inside putative priority tiger areas. Although the data were collected 8 years ago, they are supplemented with more recent information, including tiger-human conflict investigations during 2000–2005 that indicate tiger persistence at these sites. Tiger density estimates were 0.51–1.95 tigers per 100 km2. With results from other surveys, this suggests a national population of up to several hundred tigers. A thorough survey, with sufficient resources, should be carried out in the future to derive a more reliable tiger population estimate for Malaysia. Key threats are habitat loss and fragmentation, hunting of prey, commercial trade in tiger parts, and harassment and displacement. Recommendations for the recovery of tigers in Peninsular Malaysia are provided.

Abstract. Sudaryanto FX, Hardini J, Kalih LATTWS, Asrori MM, Suana IW. 2019. Bird communities and vegetation composition in Nusa Penida, Bali, Indonesia. Biodiversitas 20: 3676-3683. A study on bird community and vegetation composition in Nusa Penida was carried out to determine its diversity, conservation status, and habitat as an effort to conserve and develop birdwatching ecotourism in Nusa Penida. The study was conducted in Tembeling forest and Ped agroforestry. By using the point count method, we found 80 species of birds: 70 species in Tembeling forest and 79 species in Ped agroforestry. Fourteen species of birds are protected by Indonesian law. According to the IUCN Red List of Threatened Species, four species are Critically Endangered and one species is classified as Near Threatened. We also found eight species of migratory birds. Diversity of birds in Nusa Penida was high. Individuals of each bird species was spread evenly, except Hirundo rustica, Hirundo tahitica and Streptopelia chinensis were dominant. Twenty-five species of trees were found in Tembeling, while in Ped were found 22 species. These vegetations were provided birds with good resources for foraging, resting, and nesting.

Birds are important species that play a role in maintaining ecosystem stability. The land-use functions by humans can cause decreasing diversity of bird species. The purpose of this study was to identify species richness, species diversity, and conservation status of birds in Maron Beach, Semarang. The research was conducted in January 2017 using the point count method by five points. Observations were made at 06.00 - 10.00 WIB with a duration of 15-30 minutes for each point. The results showed that there were 42 bird species from 20 families. The species richness index (R1) showed a 6.629 value which is classified as a high category. Diversity index (H ') showed 2,915 value which is classified as a medium category. Conservation status of bird species that were protected by PP No. 7 1999, there were 7 bird species. Protected bird conservation status by P 106 2018, there were 3 bird species. The conservation status by IUCN is classified into 2 categories, that were Near Threatened (NT) and Least Concern (LC). The conservation status of international trade according to CITES indicates that no species are included in the list, but most of the bird species are traded locally.
