TNC Action Sites
Maps & Figures
Botanical, vertebrate, and invertebrate biodiversity varies among sites.
all portfolio sites in the Hawaiian ecoregion have
conservation value, identifying a subset of sites for immediate action
provides priorities under conditions of limited capacity and urgent
threats. Ideally, we want to focus attention soonest on those sites
bearing a combination of: 1) highest biodiversity value, 2) urgent, but
addressable threats, and 3) greatest feasibility and leverage.
Raw species diversity contributes to conservation value of a site.
conservation value of sites is not equal across the archipelago. Some conservation areas, such as Kaua‘i, bear much higher overall endemic species
diversity, while others might bear higher ecological system diversity
(e.g., Kona). We analyzed three factors of conservation value to arrive
at a summary rank:
values were assigned to each of the above factors and entered into
spreadsheets for analysis and ranking. Analysis details may be
accessed via the appendices. Summary conservation value ranks are shown in the table below:
- Biodiversity Richness --
overall numbers of species, natural communities, ecological systems,
and special features. Some areas with great botanical richness (e.g., Wai‘anae) scored much lower in ecological system, natural community, and special feature richness.
- Biodiversity Health --
indication of overall site viability, derived largely from overall
ecological system target viability scores. Health scores were typically
inversely proportional to level of threat to conservation targets of
-- ability of sites to contribute to overall ecoregion biodiversity, as
percent additions of selected species (flowering plants), natural
communities, and ecological systems.
||Feasibility of doing conservation work at a site is determined by many factors that affect opportunity costs.
and opportunity can change according to many factors, including practical logistics of management access, current
landowners/managers, political and social incentives and disincentives,
public support for conservation actions, pertinent policies and laws
mandating protection, history of conservation effort, regional economic health, and capacity of
conservation partners. Analyses of these factors are continually
underway by conservation planners.
Current Action Sites
conservation value as a primary driver, with some adaptation for
feasibility and opportunity differences among the conservation areas,
the action sites that emerged as highest priorities for The
Nature Conservancy are as follows, arranged by Stratification Unit:
Kaua‘i Conservation Area
No Conservation Area selected
East Maui Conservation Area
East Moloka‘i Conservation Area
Ka‘ū-Kapāpala Conservation Area
Kona Conservation Area
Remaining sites within the portfolio are approached as partnership
sites, recognizing their conservation value, and driven by opportunity.
We are committed to their protection and management, but look to
conservation partners to lead efforts while we play a more supportive role
in the appropriate partnership efforts.
priority action sites, portfolio sites, or other areas of conservation
value, the driving conservation issue is management and abatement of
threats to species, communities, and ecological systems.
