Summary

We created a comprehensive estimate of potential distribution for a subset of 17 ecosystem modifying invasive plants (EMIPs) in Hawaiʻi. This work uses methods that integrate a wide set of data sources including agency and citizen science data, but perhaps more importantly, the integration of regional and global distribution information for these species. We developed transferable and comparable general species distribution models (SDMs) at global and regional scales based on a minimum set of biologically plausible predictors. The regional models were developed for each species using only regional location data and pseudo-absences (PAs) wihtin the extent of the main Hawaiian Islands and regionally derived bioclimatic variables (250 [...]

Purpose

Despite a wide interest by conservation practitioners, there are limited reliable estimates of potential distributions for most invasive plant species across the Hawaiian Islands. To better understand current invasive plant species distributions and potential future regional spread, we used a nested modeling approach to integrate global and regional invasive species distribution projections, which provides a way to comprehensively approximate the potential full realized niche for a species, instead of just its current regional distribution. These models can be used to project potential distributions of invasive species to help prioritize conservation and management efforts such as monitoring and control.
