Locations of fire promoting alien plants across the islands of Hawaii based on field surveys and museum collections

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. Existing georeferenced herbarium data was used and ~600 specimens were georeferenced for the first time as part of this research. Data were manually reviewed to remove points which were georeferenced incorrectly or were likely misidentified.

These data to not represent the complete distribution of these grasses in Hawai'i as many areas were not surveyed, especially on Hawai'i island.

此前已有研究鉴定出夏威夷群岛的高易燃入侵植物物种，此类植物可作为夏威夷全境野火的燃料。本研究旨在对夏威夷群岛范围内这类入侵植物（以草本植物为主）的分布进行制图，以期利用其点位信息开展物种分布建模（species distribution modeling）。所有数据均为存在点位数据（presence data），未记录任何不存在点位数据（absence data）。数据采集时间大多集中在近20年内，但部分经地理配准（georeferenced）的标本馆标本（herbarium specimens）可追溯至1905年。

本研究的数据来源包括经作者审核的地理配准标本馆标本、植被样地数据（vegetation plot data）、公民科学数据（citizen science data，平台为iNaturalist），以及本研究中为开展物种制图所实施的路边调查（roadside surveys）数据。研究中使用了已有的地理配准标本馆数据，并首次为约600份标本完成了地理配准工作。所有数据均经过人工审核，以剔除地理配准错误或物种鉴定有误的点位。

由于诸多区域未开展调查（尤其是夏威夷岛区域），本数据集并未覆盖此类草本植物在夏威夷的完整分布范围。
