Ideally, we want to focus attention soonest on those sitesbearing a combination of: 1) highest biodiversity value, 2) urgent, butaddressable threats, and 3) greatest feasibility and leverage. Raw species diversity contributes to conservation value of a site. Conservation Value The conservation value of sites is not equal across the archipelago. Some conservation areas, such as Kaua‘i, bear much higher overall endemic speciesdiversity, while others might bear higher ecological system diversity(e.g., Kona). We analyzed three factors of conservation value to arriveat a summary rank: - 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 overallecological system target viability scores. Health scores were typicallyinversely proportional to level of threat to conservation targets ofthe area.
- Complementarity-- ability of sites to contribute to overall ecoregion biodiversity, aspercent additions of selected species (flowering plants), naturalcommunities, and ecological systems.
Numericalvalues were assigned to each of the above factors and entered intospreadsheets for analysis and ranking. Analysis details may beaccessed via the appendices. Summary conservation value ranks are shown in the table below: | | | Feasibility of doing conservation work at a site is determined by many factors that affect opportunity costs. | Feasibility/Opportunity Feasibilityand opportunity can change according to many factors, including practical logistics of management access, currentlandowners/managers, political and social incentives and disincentives,public support for conservation actions, pertinent policies and lawsmandating protection, history of conservation effort, regional economic health, and capacity ofconservation partners. Analyses of these factors are continuallyunderway by conservation planners. Current Action Sites Usingconservation value as a primary driver, with some adaptation forfeasibility and opportunity differences among the conservation areas,the action sites that emerged as highest priorities for TheNature Conservancy are as follows, arranged by Stratification Unit: KAUA‘I: Kaua‘i Conservation Area O‘AHU: No Conservation Area selected MAUI NUI: East Maui Conservation Area East Moloka‘i Conservation Area HAWAI‘I: Ka‘ū-Kapāpala Conservation Area Kona Conservation Area Remaining sites within the portfolio are approached as partnershipsites, recognizing their conservation value, and driven by opportunity.We are committed to their protection and management, but look toconservation partners to lead efforts while we play a more supportive rolein the appropriate partnership efforts. Whetherpriority action sites, portfolio sites, or other areas of conservationvalue, the driving conservation issue is management and abatement ofthreats to species, communities, and ecological systems.
