Hawaii a center of plant endangerment and
extinction• 110 historical plant extinctions • ~300 of 1100 native plants threatened/
endangered– 37% of all endangered plant species in US
• 201 species having fewer than 50 known individuals

Hawaiian native plant vulnerability assessment
(VA)• Goal: Evaluate the vulnerability of Main
Hawaiian Island terrestrial plant species to climate change– All Main Hawaiian Island terrestrial native
plants (~1100) are initially considered
• Iterative process– First iteration a landscape based analysis– Resulting framework potentially applied
to other species groups, other resource types

Modeling climate-driven changes to dominant vegetation in the Hawaiian Islands
• The goal of this study is to utilize a vast array of quantitative vegetation plot data to model dominant vegetation composition.
• Hawaiian vegetation is unusual in that most ecologically important species occur consistently across a wide range of physical environments, but vary greatly in local abundance, largely driven by climate.
• Changes in climate could also alter species' abundance, capacity to persist within predicted ranges, and compete for local regeneration sites.
• Uses predictive species distribution modeling (SDM) as it is an important tool in addressing conservation biology and global change issues.
• Whereas explicit spatial habitat models typically predict probability of occurrence, this project aims to generate species-specific models of estimated percent cover based in relation to several independent variables (precipitation, temperature, substrate age, etc.).

• Has compiled 145,000 vegetation data records for over 4,000 locations into a relational database in MS Access.
• These sites represent a considerable proportion of the overall climate variability in Hawaiʻi.
• Novel correlative species abundance models were generated using powerful nonlinear statistical methods, quantitative vegetation plot data, functionally relevant environmental variables, and downscaled climate models
• Aimed to identify trends and predicted future shifts in key native plant species in the Hawaiian Islands.
• As projecting species-specific abundance changes can complement and improve predictive mapping of habitat quality, inform the prioritization of habitat conservation and restoration efforts for resource managers, and support ecological resilience in the future.
