We developed habitat suitability models for three invasive plant species: stiltgrass (Microstegium vimineum), sericea lespedeza (Lespedeza cuneata), and privet (Ligustrum sinense). We applied the modeling workflow developed in Young et al. 2020, developing similar models for occurrence data, but also models trained using species locations with percent cover ≥10%, ≥25%, and ≥50%. We chose predictors from a national library of environmental variables known to physiologically limit plant distributions (Engelstad et al. 2022 Table S1) 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...
The North Central Regional Invasive Species and Climate Change (NC RISCC) network includes >100 members working at the nexus of climate change and invasive species. In late 2021, the NC RISCC leadership team surveyed regional practitioners working on issues related to invasive species management to understand their priorities and practices. Survey participants represented a variety of entities, with the most representation from: county government, academia/universities, federal government, non-governmental organizations (NGOs), and state government. They also represented all seven states in the NC region: CO, WY, MT, ND, SD, KS, and NE. Key findings include: Many practitioners in the NC RISCC network report having...
Overview Invasive species and climate change represent two of the five major global change threats to ecosystems. An emerging initiative of the Northeast Climate Science Center aims to develop management-relevant research to improve invasive species management in the face of climate change. Through working groups, information sharing and targeted research, this project addresses the information needs of invasive species managers in the context of climate change. RISCC Management is collaboratively led by the Department of Interior Northeast Climate Science Center, the New York Invasive Species Research Institute, and the University of Massachusetts to address the question “How can we manage for upcoming biological...

Horticulture could facilitate invasive plant range infilling and range expansion with climate change
Abstract (from Bioscience): Invasive plants are often sold as ornamental garden plants, but how often are species sold in the same locations as where they are invasive? To answer this question, we assessed the geography of ornamental plant sales in the United States in relation to existing invasions and potential invasion risk with climate change. Using a data set of 672 nurseries selling 89 invasive plants, we estimated the distance between nursery sales and invasive species’ observed distributions. We also used species range maps to identify nursery sales within current potential invaded ranges, as well as within species’ future potential ranges given climate change. Half of the species were sold by a nursery...
