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.

The main threat to white-tailed mice is hunting for sale. The study used the transect line method, two transect lines were made in primary forest and two transect lines were made in secondary forest, the length of the transect line was 2 km in width and 20 m in width. The results showed that in primary forest white-tailed mice made use of stratum B of (7.59%), and stratum C was (92.40%). Whereas in the secondary forest white tail rats only use the C stratum, which is equal to 100%. Activities carried out by white-tailed rats were in primary forests, foraging for (56.96%), moving activities by (30.37%), eating activities by (5.06%), and resting activities at (7.59 %). In secondary forests, white-tailed mice looked for food (54.79%), shifting activity (15.06%), eating activities (2.73%), and resting activities (27.39%).Keywords: white-tailed mice, activity, forest strates, Klabat Mountain

AbstractThe Sulawesi civet Macrogalidia musschenbroekii is endemic to the Indonesian island of Sulawesi, where it is the largest mammalian predator. Limited field data means that little is known about the species’ distribution, habitat preferences, conservation status and needs, but it is believed to depend on primary forest. We conducted camera-trap surveys across the forests of North Sulawesi, including in two of its main protected areas: Bogani Nani Wartabone National Park and Tangkoko Nature Reserve. From 148 camera trap stations and 10,371 trap nights, Sulawesi civets were recorded 17 times at 12 stations, and in almost equal numbers in primary forest, secondary forest and farmland, including the first photographic records from both the National Park and Nature Reserve. We also collected data on the Malay civet Viverra tangalunga, an introduced species of Viverridae and potential competitor. Our records (n = 21) revealed that it is established in secondary forest; it only co-occurred twice with the Sulawesi civet. With a lapse of > 20 years since the last field record of the Sulawesi civet, our findings offer new insight into its status and new enthusiasm within the provincial government for its conservation, which has led to an extension of camera-trap research into neighbouring Gorontalo province.

This paper discusses the preliminary results of the first comprehensive survey of the spiders of the Bukit Timah Nature Reserve (BTNR) in Singapore. Two plots were established in each of the three zones of vegetation, viz., primary forest, old secondary forest, and maturing secondary forest. They were repeatedly sampled over an 18-month period. Sorting of the collection so far suggests that the three vegetation zones harbour rather different spider assemblages. Only ~9% of the total spider fauna recovered was shared by all three zones. The results have also yielded a preliminary picture of dominance, abundance and rarity. Although first intended to obtain a baseline for future quantitative analyses, the survey became a testing ground to modify and refine methodology so as to conduct future quantitative surveys with greater scientific rigour. Taxonomic work on the samples so far shows that the spiders in the BTNR span over 43 families, of which six families are listed for the first time in Singapore. The tally is summarised in an interim checklist of BTNR spiders. The checklist, with a total of 317 entries, shows that there are 158 described species of spiders in BTNR, of which 25 species are new records for Singapore. Another 159 morphospecies are provisionally recognised as distinct species, some of which may be new to science. Our observations during the survey have allowed us to provide a narrative of BTNR spider diversity against a backdrop of their microhabitat specialisation.

Point Count Method

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.

The western Angola Endemic Bird Area has 14 range-restricted species. Little is known about the conservation status of the region's birds due to the civil war that has raged in Angola for the last 27 years. The greatest diversity of restricted-range species is found in Cuanza Sul province, and given the uncertainty about their current status, many of these species are listed as Threatened. In this paper we report the first significant ornithological visits to the Gabela region since 1974. We visited an extensive scarp forest patch at Kumbira Primero, near Conda, as well as smaller forest areas along the Sumbe–Gabela and Sumbe–Seles roads. Most of the threatened species were relocated, including several species not seen since the 1970s. Gabela Bush-shrike Laniarius amboimensis was common and Monteiro's Bush-shrike Malaconotus monteiri was fairly common in degraded secondary forest, old coffee plantations and primary forest at Kumbira. Pulitzer's Longbill Macrosphenus pulitzeri was fairly common at higher elevations at Kumbira as well as in the dense understorey of secondary forest west of Seles. Gabela Akalat Sheppardia gabela was less common, with only three birds found at Kumbira and one near Seles, but may have been overlooked. Only one group of eight Gabela Helmet-shrike Prionops gabela was recorded, in open woodland at the base of the scarp between Kumbira and Seles. Angola Cave-chat Xenocopsychus ansorgei was found on the rocky slopes above the forest at Kumbira. We describe the first sound recordings for five threatened species, which will help future systematic surveys of the region's forests. Vocal evidence confirms the close relationship between Gabela Bush-shrike and Lühder's Bush-shrike L. luehderi. The most pressing need is to assess the extent of remaining forests, map the distribution of key species of conservation concern, and then draft a strategy to conserve key habitat blocks.

AbstractThe distribution of the endemic threatened plant Camellia changii Ye (Family Theaceae) is restricted to a small area in southern China, and little else is known about its status in the wild. To provide information for the conservation of C. changii we investigated its distribution, population size and structure, and habitat, and assessed its conservation status. Surveys confirmed that the species grows in a narrow band along both sides of a 4 km long segment of a stream in Ehuangzhang Nature Reserve, under the discontinuous canopy of a secondary evergreen broadleaved forest on well-drained, acidic sandy loam soil. We found a total of 1,039 individuals of C. changii. The population has a high flowering rate but a low seed-setting rate. The population appears to be in decline because no seedlings and few young plants were evident. Our findings indicate that C. changii should be categorized as Critically Endangered on the IUCN Red List. We have recommended an integrated species-conservation plan for the species that includes patrolling the Ehuangzhang Nature Reserve to prevent plant removal, establishing an ex situ living collection that contains the entire wild genetic diversity (accomplished by grafting of short cuttings from all wild individuals), facilitating propagation for commercial use, and implementing reintroduction to augment the wild population.

SummaryThe critically endangered Sichuan Hill-partridge Arborophila rufipectus occupies a restricted range in south-central China. Field surveys within this range were undertaken using line transects in 1996 and 1997. Calling males were recorded from nine subtropical forest tracts within an area totalling 1,793 km2 and consisting of primary, natural secondary and replanted broadleaf forest between 1,100 and 2,235 m elevation. The only sightings obtained were in primary forest. The mean density of calling males estimated from data collected during transect surveys was 0.48 ± 0.06 and 0.24 ± 0.16 calling birds km−2 in 1996 and 1997 respectively. There was no difference in density estimates for calling males between primary forest and secondary/replanted broadleaf forest. The principal threat to the continued survival of the species is clear-felling of primary forest, but clear-felled areas are often replanted with native broadleaf trees and records of Sichuan Hill-partridge calls in such plantations offers hope for its future survival. Forest management should be modified to make forestry practices more sympathetic to the conservation of the Sichuan Hill-partridge.

Artain is a village located opposite the Riam Kanan reservoir in Aranio District, Banjar Regency, South Kalimantan Province. There are various types of habitat in the Village, from the edge of a reservoir to primary forest which is thought to be home to various birds species, which over time has the potential to degrade or change due to human activity which then reduces its quality and function as habitat for many birds species. It is necessary to research the diversity and evenness of birds in each habitat type in Artain, so that the existence of various bird species can be known. The research was conducted from May to June 2020, the method used in the study was the cruising circumference point, which is determining the observation point and its radius and then making observations by exploring the observation path continue. The results showed that there were 9 types of bird's habitat in Artain, they are Settlements, Periphery Reservoirs, Shrubs, Mixed Gardens, Rubber Gardens, Reeds, Fields, Secondary Forests, and Primary Forests. The lowest diversity value (H' = 1.25) was identified in field habitats and the highest (H' = 3.17) in scrub habitats, meaning that the level of diversity in all habitats was classified as moderate. The lowest evenness value in secondary forest habitats (E = 0.80) and the highest is mixed garden habitats and rubber gardens (E = 0.97), which means that evenness in each habitat is in the high category.
