Cheirodendron dominii is assessed as Endangered. Its estimated population is 17,000 individuals among only five subpopulations in four separate, threat-based locations. The species has an area of occupancy of 80 km2 and an extent of occurrence of 195 km2 and there is continuing decline in both of these parameters, in the extent and quality of the habitat and in the number of mature individuals due to the impacts of invasive species.

Habitat and Ecology [top]

Habitat and Ecology:The taxon is a large shrub to small tree of wet forests on the high central plateau of Kauaʻi dominated by Dicranopteris linearis, Metrosideros polymorpha, and Acacia koa. Other associated native plant species may include Broussaisia arguta, Cyanea fissa, C. sylvestris, C. kahiliensis, Antidesma sp., Polyscias oahuensis, Hesperomannia lydgatei, Kadua affinis, Pipturus kauaiensis, Psychotria mariniana, P. greenwelliae, Myrsine sp., Platydesma sp., Labordia sp., Wikstroemia oahuensis, Scaevola procera, Bobea brevipes, Dodonaea viscosa, Ilex anomala, Coprosma kauaensis, Cheirodendron trigynum, Melicope clusifolia, Machaerina angustifolia, Cibotium spp., Clermontia fauriei, Trematolobelia kauaiensis, Vaccinium calycinum, Dubautia laxa, and Santalum freycinetianum var. pyrularium.
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): Major threats include habitat degradation by feral pigs, goats and deer, rats and slugs, and displacement by invasive non-native plant species such as Psidium cattleianum, Rubus rosifolius, Cyathea cooperi, Hedychium gardnerianum, Buddleja asiatica, and Clidemia hirta. Erosion and landslides are also a threat. Furthermore, Fortini et al. (2013) characterized this taxon as vulnerable to climate change (vulnerability index 0.755).

Conservation Actions [top]

Conservation Actions: Cheirodendron dominii is not listed by the U.S. Fish and Wildlife Service or the State of Hawai'i. There is currently no recovery plan in place, and monitoring is infrequent. Fencing has been constructed that may protect some individuals, and some control of Australian Tree Fern and Kahili Ginger is conducted by the Kokeʻe Resource Conservation Program.
