Introduction

I am interested in predicting how terrestrial ecosystems will respond to anthropogenic disturbance and climate change. I focus primarily on non-native invasive plants, with a goal of better understanding the biogeography of invasion risk.

Anthropogenic Ignitions
(2016-01) Fusco, Emily J.; Abatzoglou, John T.; Balch, Jennifer K; Finn, John T; Bradley, Bethany
This dataset contains ignition points derived from the MODIS Burned Area Product (MCD45) from 2000-2012), It also contains a random subset of unburned points. Both ignition and unburned points have associated anthropogenic feature data.

Regional Invasive Species & Climate Change Management Challenge: Prioritizing range-shifting invasive plants High-impact species coming to the Northeast
(2020) Bradley, Bethany; Allen, Jenica; Griffin, Bridget; Laginhas, Brittany B.; Rockwell-Postel, Mei
Prevention of new invasions is a cost-effective way to manage invasive species and is most effective when emerging invaders are identified and prioritized before they arrive. Climate change is projected to bring nearly 100 new invasive plants to the Northeast. However, these plants are likely to have different types of impacts, making some a higher concern than others. Here, we summarize the results of original RISCC research that identifies high priority, range-shifting invasive plants based on their potential impacts.

Northeast Invasive Plants Data
(2017-01-01) Cross, Tyler; Finn, John T; Bradley, Bethany
The data are distribution and ranked abundance data for thirteen invasive plants in the Northeast US compiled from various spatial repositories for invasive species. iMAP invasives data are not included in this dataset because they are not publicly available. iMAP data can be requested from individual states. These data form the basis of analyses presented in Cross et al. 2017. "Frequency of invasive plant occurrence is not a suitable proxy for abundance in the Northeast US Ecosphere".

Regional Invasive Species & Climate Change Management Challenge: Do Not Sell! Ornamental invasive plants to avoid with climate change
(2022) Allen, Jenica; Beaury, Evelyn M.; Mazzuchi, Julia; Nelson, Michael; O'Uhuru, Ayodelé; Bradley, Bethany
Climate change is likely to bring dozens of new invasive plants to the Northeast. Despite their invasive tendencies, many of these species are sold as ornamental plants in slightly warmer climates, but are not yet a large part of nursery sales in the Northeast. By avoiding these species, we protect our native ecosystems from future invasive species impacts. We also present alternative native plants that provide similar aesthetics while also supporting biodiversity.

Ignition Cause

This dataset contains ignition points derived from the MODIS Burned Area Product (MCD45) from 2000-2012), It also contains the determined cause for each ignition.

Regional Invasive Species & Climate Change Management Challenge: Double Trouble. Understanding risks from invasive species + climate change
(2019) Bradley, Bethany; Beaury, Evelyn M.; Fusco, Emily J.; Griffin, Bridget J.; Laginhas, Brittany B.; McLaughlin, Blair C.; Munro, Lara
Individually, invasive species and climate change are major threats to global ecosystems. Together they create new challenges for effective management. Before we can design management strategies to respond to this double trouble, we need to understand how these two forms of global change interact.

Regional Invasive Species & Climate Change Management Challenge: Gardening with climate-smart native plants in the Northeast
(2020) Bradley, Bethany; Bayer, Amanda; Griffin, Bridget; Joubran, Sydni; Laginhas, Brittany B.; Munro, Lara; Talbot, Sam; Allen, Jenica; Barker-Plotkin, Audrey; Beaury, Evelyn M.; Brown-Lima, Carrie; Fusco, Emily J.; Mount, Hailey; Servais, Bailey; Morelli, Toni Lyn
An estimated 80% of ornamental plants for sale are non-native. This means that the average yard does a poor job of supporting native flora and fauna. By shifting our plantings towards natives, we can dramatically increase the diversity of bees, butterflies, birds and other animals. In contrast, non-native plants do not support local food webs and can become invasive. Native plants increase biodiversity and reduce risks associated with invasive species, which supports resilient ecosystems in the face of climate change.

Regional Invasive Species & Climate Change Management Challenge: Taking Action. Managing invasive species in the context of climate change
(2020) Beaury, Evelyn M.; Barker-Plotkin, Audrey; Brown-Lima, Carrie; Fusco, Emily J.; Griffin, Bridget; Joubran, Sydni; Laginhas, Brittany B.; MacLean, Meghan Graham; Munro, Lara; Nelson, Michael; Talbot, Sam; Bradley, Bethany
Climate change is likely to alter the timing and effect of invasive species management, as well as the suite of species we are managing. Despite concern about the effects of climate change, lack of information about how and when to take action is a barrier to climate-smart invasive species management. Here, we outline strategies for incorporating climate change into management along with examples of tools that can inform proactive decision-making.

Species Potential Range Predictions (Out of the Weeds? Reduced Plant Invasion Risk with Climate Change in the Continental United States)
(2016-01-01) Bradley, Bethany; Allen, Jenica
This PDF file contains the binary potential range prediction maps for each species in the dataset under current climate. The prediction map for each species lists the species code (see Supplemental Online Table S2 for full species names), areas predicted to be climatically suitable/unsuitable under current climate, and the occurrence points for the species. See the main publication for model fitting details.

Regional Invasive Species & Climate Change Management Challenge: Preparing for sleeper species
(2018) Bradley, Bethany; Beaury, Evelyn; Fusco, Emily J.; Laginhas, Brittany; Pasquarella, Valerie
Many naturalized non-native species never become invasive and generally are not prioritized for management due to limited resources. However, climate change could enhance the success of these species, causing some to become invasive. Therefore, we need to reassess the current pool of naturalized species to identify and prioritize management of ‘sleeper’ species.
