Previous research identified species of invasive plants in Hawai'i which are highly flammable and act as fuels in wildfires across Hawai'i. This work aimed to map the distribution of these species (largely grasses) around the islands of Hawai'i with the goal of using the locations for species distribution modeling. All data represents presence data, no absence data were recorded. Data are largely from within the past 20 years, but some georeferenced herbarium specimens go as far back as 1905. Data were obtained from georeferenced herbarium specimens, vegetation plot data, citizen science data (iNaturalist) reviewed by the authors, and data from roadside surveys conducted as part of this research to map these species....

This raster indicates modeled habitat for various species under current and future conditions. Using the Price et al. (2012) parameters, we modeled species ranges as a function of elevation, temperature, and precipitation as described in Jacobi et al. (2016). Our methods departed slightly from their procedure in that we did not exclude non-pioneer-classified species from young lava flows.

The spreadsheets associated with this metadata file represent: (Tab 1) Streamflow and drainage basin characteristics of selected gaged steams in Hawaii used to develop statistical models to estimate surface-water availability during low flow conditions and for varying rainfall conditions. For gaged streams on Maui, two sets of projected rainfall conditions for the late 21st century and associated estimates of changes in low flows and usable habitat for native stream fauna are also provided. (Tab 2) Drainage basin characteristics of ungaged streams on Maui used to apply the statistical models, two sets of projected rainfall conditions for the late 21st century, and associated estimates of changes in low flows and...
We developed a screening system to identify introduced plant species that are likely to increase wildfire risk, using the Hawaiian Islands to test the system and illustrate how the system can be applied to inform management decisions. Expert-based fire risk scores derived from field experiences with 49 invasive species in Hawai′i were used to train a machine learning model that predicts expert fire risk scores from among 21 plant traits obtained from literature and databases. The model revealed that just four variables can identify species categorized as higher fire risk by experts with 90% accuracy, while low risk species were identified with 79% accuracy. We then used the predictive model to screen 365 naturalized...

Wildfire is a dominant ridge to reef threat to human and natural communities in the Hawaiian Islands, with impacts to natural and cultural resources and ecoystem services. Fire regimes in Hawaii have shifted from very infrequent wildfire occurrence prior to human arrival to greatly increased frequency, intensity, and size over the past 100+ years, almost all of which is driven by anthropogenic ignitions and wildland fuels associated with invasive species, particularly grasses. Recent fire science has greatly increased understanding of contemporary drivers of fire in Hawaii; however, the social dimensions and historical perspectives from Hawaiian language primary sources have not been integrated into synthetic understanding...
