Scientific Name: Phyllostegia kaalaensis
Species Authority: H.St.John
Taxonomic Notes: Information from NatureServe (2003): "According to a personal communication cited in the Federal Register of Oct. 2, 1995, Warren Wagner concurs with St.John (who apparently described Phyllostegia kaalaensis in 1987) that P. kaalaensis is a valid, taxonomically distinct species. Kartesz (1999) recognizes it."

Major Threat(s): Threats include pigs, introduced alien plant species. There is also a possible threat from fire.

Conservation Actions [top]

Conservation Actions: The Army has adopted a fire management plan that includes realigning targets and establishing firebreaks. These actions may aid in protecting this species from the threat of fire. The completion of a boundary fence on the south and southeast perimeter of Makua Valley, along with continued goat control efforts, should help to protect this species from goat damage. This species is being successfully propagated at the National Tropical Botanical Garden , the Waimea Arboretum, at DOFAW's mid-elevation Nike facility at Pahole (B. Garnett, G. Koob, D. Orr, and S. Smith, pers. comm. 1997). Federally and state-listed as an endangered species.
