The site was identified as internationally important for bird conservation in 2009 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Hawaiian Goose Branta sandvicensis	NT	resident (2002)	83 birds	A1, A2, A4i
Hawaiian Petrel Pterodroma sandwichensis	EN	breeding (2001)	present	A1
Newell's Shearwater Puffinus newelli	CR	breeding (2007)	present	A1, A4ii
Kauai Elepaio Chasiempis sclateri	NT	resident (2000)	23,000 birds	A1, A2
Puaiohi Myadestes palmeri	CR	resident (2007)	400 birds	A1, A2
Akikiki Oreomystis bairdi	CR	resident (2007)	1,312 birds	A1, A2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2009) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	Unknown	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
-	Ku‘ia	Natural Area Reserve (V)	1
-	Alaka'i Wilderness Preserve	Preserve (-)	-
1981	Alakai	Wilderness Preserve (V)	6
1983	Hono O Na Pali	Natural Area Reserve (V)	2

Land use	% of IBA
nature conservation and research	89
hunting	11

The majority of lands comprising the Kaua`i Forests and Uplands IBA are owned by the State of Hawai`i (62%), with the remainder being privately owned lands that are administered by the State of Hawai`i as forest reserves (38%), and less than 1% owned by The Nature Conservancy of Hawai`i. State lands include the Alaka`i Wilderness Preserve (6%), the Hono O Na Pali and Kuia Natural Area Reserves (2%), all or parts of the Halelea, Moloa`a, Na Pali-Kona, Kealia, Pu`u Ka Pele, and Lihue-Koloa State Forest Reserves (36%), Koke`e, Waimea Canyon, Haena, Na Pali Coast, and Polihale State Parks (7%), and the Wailua, Kekaha, and Mokihana State Game Management Areas (11%)
