This layer depicts projected abundance of native and non-native plant species in the main Hawaiian Islands with high levels of uncertainty removed in post-processing. To estimate native and invasive species abundance in baseline climate conditions, a map was generated that considered abundance as percent cover and used high coefficient of variation values as a mask. The primary sources for post-processing the uncertainty masks are the Hawaiian Islands plant species abundance modeled means and standard deviation values (Wong et al., in preparation). These maps cover the entire landscape (including urban and agricultural areas), and therefore they can be applied in a variety of ways. Maps can be utilized to evaluate...

Several cut disks and tree cores of Mamane trees growing on Hawaii Island that were subsampled and analyzed for carbon isotope determination. Isotope determination is at the 100µm resolution; tree samples are within an area of ~100 km2.

Taken from the DMP: "Georeferencing of plots and determination of site conditions using GIS. Accuracy of plot abundance values assessed with vegetation maps, satellite imagery, and expert consultation. Ten native and five invasive species of trees, shrubs and ferns were selected based on their potential ecological importance in communities, as well as how much field data was available to analyze for this study. For baseline climate condition variables, we used surface temperature and rainfall estimates (30 year baseline period, 1978–2007) developed by Giambelluca et al. (2013) with grid cell resolution of 250m. To estimate climate change responses, we used future projected climate variables developed by the International...
