This rare bog community only occurs in the Maui Nui Stratification Unit.
The insular nature of the
Kaua‘i Unit – The islands of Kaua‘i and Ni‘ihau. Kaua‘i in particularis a hotbed of endemic biodiversity. The channel separating Kaua‘i from therest of the archipelago is the widest, leaving the oldest high island most isolated andbiologically distinct.
O‘ahu Unit – The
Hawai‘i Unit –The large, geological youngest
It is fortuitous that the stratification units above alsocorrespond with political (county level) units, so that overarching strategiesneed not require multijurisdictional agreements. With the exception of MauiNui and Kaua‘i units, the stratification units also correspond with individualislands. The individual islands also form meaningful stratification subunits.
This shrubland of the silversword relative iliau (Wilkesia gymnoxiphium) is restricted to the Kaua'i Stratification Unit.
Map of Stratification Units:
Four stratificationunits reflect the biogeography of the islands: Older islands (Kaua`iand O`ahu are botanically rich, while the Maui Nui cluster sharesimilar age and biology. The youngest and largest Island of Hawai`i isalso biologically distinct.
Only the youngest, largest islands bear alpine zones, with snow during winter.
Target distribution within thestratification units above is not even. For example only the islands of
For example, althoughoccurrences of the Lowland Wet Ecological System occur on six of the eight islands, on onlythree (Kaua‘i, Maui and Hawai‘i) are there large,exemplary occurrences that emerge as highest priority action sites for protection ofthis conservation target.
