INHABIT species potential distribution across the contiguous United States

We developed habitat suitability models for invasive plant species selected by Department of Interior land management agencies. We applied the modeling workflow developed in Young et al. 2020 to species not included in the original case studies. Our methodology balanced trade-offs between developing highly customized models for a few species versus fitting non-specific and generic models for numerous species. We developed a national library of environmental variables known to physiologically limit plant distributions and relied on human input based on natural history knowledge to further narrow the variable set for each species before developing habitat suitability models. We developed models using five algorithms with VisTrails: Software for Assisted Habitat Modeling [SAHM 2.1.2]. We accounted for uncertainty related to sampling bias by using two alternative sources of background samples, and constructed model ensembles using the 10 models for each species (five algorithms by two background methods) for four different thresholds. Each species folder contains the potential distribution of the species and all raster layers were produced using VisTrails:SAHM [SAHM 2.1.2]. Each of the 8 rasters represent the following: 1) MPP - minimum predicted presence threshold 2) 0.01 - one percentile threshold 3) 0.1 - ten percentile threshold 4) MaxSS - maximum sensitivity plus specificity threshold 5) MPP - minimum predicted presence threshold with Restricted Environmental Conditions 6) 0.01 - one percentile threshold with Restricted Environmental Conditions 7) 0.1 - ten percentile threshold with Restricted Environmental Conditions 8) MaxSS - maximum sensitivity plus specificity threshold with Restricted Environmental Conditions These rasters will be integrated into the Invasive Species Habitat Tool (INHABIT), a web application displaying visual and statistical summaries of nationwide habitat suitability models for manager identified invasive plant species.
