Infrastructure layer of sewage pumps in Palau (from PALARIS) with elevation data (from USGS 10-m DEM)

Measurements of fog, wind, fog interception, soil moisture, and fog effects on plant water use and plant survival were collected to test a model to estimate CWI as a function of fog-water movement and vegetation characteristics.

This research provides insight on Native Hawaiian relationships to drought historically as well as current practices within community-based management. Of importance are historical records of drought spanning short term in one section of an island to three generations across multiple islands. This dataset represents a survey of the Ulukau, Papakilo Database, and Kuluwaimaka Collection from the Bishop Museum for drought related environmental changes and natural climate indicators, traditional responses to related disasters. First, a review of Hawaiian proverbs (‘ōlelo no‘eau) related to drought and elements impacted by drought (e.g., plants, food resource, death, famine) identify perspectives that reflect household...

To examine Palau residents’ reliance on reef fish, we reviewed published peer-reviewed literature, non-governmental organizations’ surveys, and unpublished data from a survey conducted by this project’s team. Volume of reef fish caught, consumed, and bartered at periurban, urban, and rural states was compared to the area of reefs within state waters to calculate fishing pressure. Data on fish residential consumption was triangulated and synthesized across data sources, including PIs Oleson and Lewis’ unpublished data from a resident survey conducted in 2018, an SPC dataset of fisher households conducted in 2018, and peer-reviewed literature.

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....

Measurements of fog, wind, fog interception, soil moisture, and fog effects on plant water use and plant survival were collected along with these vegetation data to test a model to estimate CWI as a function of fog-water movement and these vegetation characteristics.

Data of a calibrated fog gauge at each of the five stations. Parameters include total fog water collection, wind-driven rain collection, fog-only water collection, cloud water flux, and cloud liquid water content.
The outputs of two versions of the Single-Layer Wet Canopy Water Balance model. Parameters include cloud water interception, evaporation of rainwater or fog water from wet canopy (interception evaporation), and canopy water storage.

These spatial data layers form the bases for the Governance Vulnerability Analysis which is incorporated into the project's Story Map which integrates resident consumption, spatial and climate vulnerability, and governance analysis, with research findings discussed at the end.

Catchments for the island of Babeldaob, Palau. Data from Povak et al. (2020) and calculations with sediment yield per catchment added for this project.

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...
