The Penan Benalui were nomads living in the forest of the interior part of Borneo until they settled down in villages in the 1960s. During the fieldwork in a Penan Benalui village in 2002, about 560 species of wild plants were collected and their ethnobotanical features were documented. Informants could identify most of the plants and gave about 550 local names. About 75% of the plants were reported to be in use and there were about 70 different uses. The difference in ethnobotanical knowledge was large between men and women of the younger generation. Men knew plants better than women. This was probably because men still go to the forests very often for hunting and gathering while women spend more time in the village.

They had similar numbers of plant names, but the Penan used seven times more binomial names than the Baka. Plant diversity patterns and the total numbers of useful plants were similar among the study sites, and thus cannot explain the difference. There is some evidence that the Baka have been replacing their plant names with borrowed ones of farmer languages, probably reducing the number of binomial names. The two groups exhibited rich knowledge of useful plants, especially for various kinds of tools and light construction. The Baka, however, reported six times more plants for medicinal purposes than the Penan. It is generally considered that a nomadic way of life is relatively free from infectious diseases, but both of the study groups settled several decades ago. The Penan could visit a clinic in a nearby village, while the Baka needed to treat health problems by themselves. At the same time, the Baka had a broad and flexible idea of medicine and they were also less selective in choosing the medicinal plants than the Penan. Furthermore, the medicinal practice of the Baka had a social role. These factors should have contributed in their search for new medicinal plants

Birds often have symbolic meanings and are related to traditional culture and belief systems (e.g., Feld 1988; Hagiwara 1996). In Borneo, people practice bird augury, and it affects people’s activities (e.g., Hose and McDougall 1901; Richards 1971; Jensen 1974; Sather 1984). Birds also economically contribute to people’s life. Bird’s nests and hornbill’s casques, for example, have been traded by local people of Borneo to Chinese traders (Freeman 1999). Birds contribute to people’s culture and economy and at the same time use habitats created by human activities. Traditional coffee agroforests have proved to create a complex habitat and support a rich avifauna. (Moguel and Toledo 1999). Different human management of lands results in different compositions of birds even under the same area (Kataoka, Iwata, and Pr...

However, the measures for improving the maintenance of biodiversity and high biomass are not well evaluated. For this study, we established vegetation plots in the Anap Sustainable Development Unit (ASDU) in Bintulu, Sarawak, including the Anap-Muput Forest Management Unit (AMFMU), in order to investigate the distribution of above-ground biomass and tree species diversity. Using a Landsat image, we mapped the distribution of above-ground biomass all over the ASDU as of 2009. This distribution of above-ground biomass inside the AMFMU was not well correlated with the time that had elapsed since the last cycle of logging. The topography of the area may in fact be a more important factor. In total, 986 tree species were recorded i...

(Rubiaceae) is a genus of small dioecious trees that grow in primary and disturbed forests and in open places. Of the 49 described species, 23 occur in Borneo, 19 in the Philippine islands, and 7 in Sulawesi. Praravinia is allied to Urophyllum Jack ex Wall. and cannot be distinguished from Urophyllum only by vegetative characters. Praravinia differs from Urophyllum sensu Bremekamp in having fasciculate or solitary inflorescences (umbellate or solitary in the latter), sessile or subsessile flowers (pedicellate in the latter), heteromerous calyx and corolla (isomerous in the latter), and straight white hairs on the corolla throat (torulose pale yellow hairs in the latter) (Bremekamp 1940a, 1940b, 1940c). Based on phylogenetic analyses of DNA, Maschalocorymbus Bremek., Pleiocarpidia K. Schum., and Pravinaria Bremek. were recently subsumed under Urophyllum (Smedmark & Bremer 2011, Govaerts et al. 2016). Urophyllum is now more diverse, while Praravinia differs from it only in the heteromerous calyx and corolla. Molecular systematic studies suggest that Praravinia may not be phylogenetically separable from Urophyllum, although only one species of Praravinia, not the type species, was included in the analyses (Smedmark et al. 2008, Smedmark & Bremer 2011). Further study is necessary

They have a detailed classification system for wild plants and recognize many useful wild plants, but their use knowledge is relatively simple and differs from that of Bornean farmers. Men are more knowledgeable than women about forest plants. Men often hunt in the forest and collect forest products, whereas women spend most of their time in the village. This suggests that ethnobotanical knowledge is closely related to forest activities. At the same time, the Penan Benalui have more than enough knowledge from a utilitarian point of view, and gaining knowledge depends to some extent on personal experience. The nature of the Penan Benalui classification of wild plants does not support previous theories regarding the relationships among use, classification, and nomenclature of organisms. It is possible that nomenclature patterns affect the classification mechanism.
