The Bornean ground-cuckoo is categorized as Lower Risk: near threatened and the Bornean peacock-pheasant as Endangered on the IUCN Red List (Collar et al., 2001; IUCN, 2003), with most of the confirmed records concentrated in the central part of the island. From the scant data available it seems that both species are generally confined to the low-lying forest below 500 m altitude, a habitat that once covered a considerable part of the island. Over the last decade, however, the decrease of lowland forest on Borneo, and especially alluvial forest, has been dramatic. It has been suggested that this habitat type will have been lost to logging, plantation development and forest fires by the end of this decade (Jepson et al., 2001). The impact of uncontrolled forest fires is especially severe, with millions of hectares of forested land affected over the last decades (Siegert et al., 2001). For effective conservation of the Bornean ground-cuckoo and the Bornean peacock-pheasant it is of utmost importance to gain greater insight into their habitat preferences and how to effectively manage forest areas for their requirements.
