Kaua‘i Conservation Area Profile
Ecological Systems: Sixecological systems of Kaua‘i were selected as conservationtargets, each bearing nested natural communities and species (discussedbelow).
Kaua'i Lowland Dry Systems have POOR viability and are not included.
Selected stream occurrences: Kaua‘i bears manyhigh quality streams, and the four streams selected: Lumaha‘i, Limahuli, Waimea, and Hanakāpī‘ai Streams are among thelargest and highest quality streams on the island (Hawai‘i Stream Assessment 1991). Eachbears a rich complement of native macrofauna and high volume, high qualitywater in a channel with high structural heterogeneity.
Special Ecological Features:
The Kaua‘i Forest Bird Concentration is one ofthe most significant in the archipelago, bearing eight avian species, including fivetaxa endemic to the island, and two endangered species.
The Kaua‘i Waterbird Concentration is defined as fivecore wetlands and at least seven of nine wetland sites identified by the USFWSWaterbird Recovery Plan (2005). These include coastal, riverine, and uplandsites largely outside of the ecological system targets.Nested Targets:
‘Ōhi‘a/Uluhe Lowland Wet
‘Ōhi‘a/Mixed Shrub Montane
Koa/‘Ōhi‘a Montane Mesic
Kaua‘i Diverse Mesic
Hawaiian Montane Bog
Hawaiian Lowland Bog
Mixed Fern/Shrub Wet Cliff Community
Mixed Shrub Dry Cliff Community
There are manyconstituent native species that comprise the natural communities of the ConservationArea. Highlights include over 80 rare/endangered plant species, 383 endemicplant species, and an untold number of endemic invertebrate species likelynumbering in the thousands.Major Threats:Uncontrolledferal ungulates (primarily pigs, goats, deer); and a large variety ofinvasivealien plants, particularly following hurricane ‘Iniki in 1991.Noteably, Kaua‘i is the only major island without mongoose (Herpestes auropunctatus), an important alien predator of native birds.
| Thenative-dominated ecological systems of Kaua‘i occupy itsremote and largely trackless central region, extending downward into areas (pink) converted into anthropogenic andalien-dominated regions. || |
|The conservation portfolio for the Island of Kaua'i includes the majority of native-dominatedecological systems (dark green), and four occurrences of the Hawaiian continuous perennialstreams (Hanakāpī'ai, Limahuli, Lumaha'i, and Waimea) shown in light blue.|
