Population size, distribution and status of the remote and Critically Endangered Bawean deer Axis kuhlii

Conservation of rare ungulates requires reliable population size estimates and distribution maps for prioritizing investments and assessing the effectiveness of conservation measures. We used both camera trapping and a random encounter model approach, and faecal pellet group counts, to update the range and population size of the Bawean deer Axis kuhlii in the Bawean Island Nature Reserve and Wildlife Sanctuary, Indonesia. We studied 2-month periods to fulfil the assumption of population closure. Both methods provided similar population density estimates (higher in the dry season) of c. 227–416 individuals. The estimated range of the species is significantly narrower than previously reported. The main threats (habitat loss as a result of illegal logging, and disturbance by dogs and hunters) are ongoing. Based on these results we suggest that the species should retain its Critically Endangered status on the IUCN Red List.

The objective of this research was to identify various kinds of Orchidaceae epiphytes and their porophyte in the logged over forest of 12 hectares within Malinau Research Forest (MRF-CIFOR) Seturan – Ddistrict of Long Loreh, Malinau.Regency. The research found 37 species with 2, 4 individual orchids epiphytes at each phorophyte. The Bulbopphyllum beccariu Rchb.f. is the most one orchids epiphytes at the crown and at the bark trees. The Dominant Index Species (C) at the crown ,.04141 and at the bark 0,34551. The Various Index of Species (H) at the crown 1,3801 and at the bark 0,46975. The Similarity Index of spcies from Shφrensen(ISs) at the crown 16,22.

Benefit of camera trapping for surveying the critically endangered Bawean deer Axis kuhlii (Temminck, 1836)

Despite being one of the rarest deer in the world, the critically endangered Bawean deer Axis kuhlii has received little conservation attention. Fauna monitoring is usually limited by lack of resource; therefore, the choice of a relevant methodology is fundamental to maximize the cost–benefit ratio. We compared the performance and cost of three direct and indirect methods to survey Bawean deer in protected areas of Bawean Island. Camera trapping provided a high number of records of Bawean deer (118 for 5500 camera days) and ascertained identifications of several other species. The number of photographs increased with the dry season. Transect sampling was time-consuming in the field for a poor result (two records for 19.200 h). Faecal pellet group count was more successful (80 pellet groups for 9.600 h of fieldwork). Camera traps are expensive to buy, but they lighten the field work and provide much data for further analyses.
