All members of the genus Isodendrion are known by the common Hawaiian name of aupaka. Lipochaeta venosa and Isodendrion hosakae are found at all sites where they were historically known, and L. venosa is found at one additional site. Currently, these species are found in the cattle pastures of Parker Ranch and the adjacent Hawaiian Home Lands. The area is typically dry and windy, and the soil is well drained and composed largely of volcanic cinder or ash material. There are an estimate five populations of L. venosa with about 2,200 individuals, and three populations of I. hosakae including about 350-375 individual plants.
Research needs to be conducted to determine habitat requirements for both species.
Management efforts are aimed at preventing grazing and wildfire on habitat for one or both of these plant species. No seeds of these two species exist in any seed banks. None at present time.
