Carbon Neutral Landscapes - Hawaii as a model system for reducing the global warming potential of the atmosphere. This Modification to our agreement with the Arizona State University will provide continued support for core research in understanding landscape scale dimensions of carbon neutrality planning. This work will continue developing a next generation understanding of terrestrial carbon sources and sinks by Island across the state of Hawaii - relying on a diversity of datasets required for conducting the proposed global warming potential of each island. This research has assembled a diverse working group representing organizations and partnerships committed to creatively achieving neutrality locally, nationally and internationally. Asner and collaborator Roberta Martin based at the USFS - IPIF are positioned to develop a new understanding of how disease is impacting the most important native tree species in Hawaii, and the forest structure implications of Rapid Ohia Death for carbon management. Specific work will be focused on protection of native biodiversity, and enhancement of ecosystem services objectives of the USDA Forest Service. Specifically, this new work will integrate advanced remote sensing methods into the pre-screening of survivor Metrosideros species, which show promise being resistant to C. lukuohia and C. huliohia (known locally as rapid Ohia death - ROD). We will: (1) use time series analyses to distinguish which survivor trees are escapes (leaf chemistry follows patterns of pre-symptomatic individuals that eventually die from ROD) and which appear to be actual survivor trees (leaf chemistry that is characteristic of healthy); (2) develop a work flow to automate the identification of live ohia trees within high mortality patches; (3) expand our ground based sampling of remotely sensed individual ohia trees to refine what appears to be a strong relationship between laboratory based leaf chemistry and hyperspectral signatures of a tree's canopy; (4) Improve green-house assay outcomes. From this work, genotypes with putative resistance can examined for follow up work to identify and sample from a much larger pool of available trees. By developing a process for operationalizing the identification of potentially disease resistant ohia trees through our approach of remotely pre-screening remnant surviving ohia based on leaf characteristics, we can greatly accelerate the time to finding low susceptibility genotypes that can be used for carbon focused forest restoration. In addition, the work can support forecasting the impact of ROD on forest structure, helping to support the health of Americas rural, wildland, and urban forests. The focus on building awareness of the value of public lands and native ecosystems, of the cultural linkages that have tied Hawaiis people to the land for millennia, as well as providing an appreciation to learners of the diverse threats to this natural and cultural legacy aligns with Forest Service goals of enhancing diversity of our workforce and the people we serve. This modification also supports our expansion of research on sustainable Stewardship of the Hawaii Experimental Tropical Forest, with the overall goal to enhance the sustainability and resilience of ohia and these forests through efficient investments into understanding disease resistance. To achieve this goal, funding will used to create a deeper understanding of where disease resistant trees are located. The new funding for this project will rely on collection of remote sensing of the HETF and surrounding forests with this work anticipated to be completed in the coming 18 months.
