Interactions between invasive species and climate change present new challenges for resource management. Prior to a new study by NE CASC fellow Evelyn Beaury and her collaborators, however, it was unclear what the common concerns, strategies, limitations, and research needs were for managing invasive species in a changing climate. In their nationwide survey of invasive species managers from government, non-profit, and private organizations, Beaury's team found that while the majority of managers are very concerned about the influence of climate change on invasive species management, the organizations they represent are typically far less engaged with this issue. This study illustrates that the complicating challenge of climate change may open a new avenue for elevating the efficiency and success of current invasive species management efforts if a collaborative approach is adopted in this area.

The combination of invasive species and climate change creates unique challenges for natural resource managers. We are developing a network of experts to produce useful and usable science to protect native systems and enhance resilience in the North Central region (CO, WY, KS, NE, SD, ND, MT). This project will expand the successful model of the Northeast Regional Invasive Species and Climate Change Management Network to the North Central region of the U.S. This effort will integrate the research and management of invasive species, climate change, and fire under one umbrella. Stakeholders in the North Central region have identified invasive species, woody encroachment, wildfire, and habitat and ecological transformation as key management issues which this project will address. Project length:  Jun 2, 2021 through Jun 1, 2023.

Invasive species and climate change represent two of the five major global change threats to ecosystems. An emerging initiative of the Northeast Climate Adaptation 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. The working group combines climate and invasive species scientists with invasive species managers and policy makers from the northeast to promote a two-way dialogue to 1) share regional knowledge about current management strategies and scientific insights; and 2) identify and address planning and information needs of managers related to invasive species and climate change.

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. 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 invasions in the light of climate change?” 

Biocontrol is an important management tool that utilizes one species (a biocontrol agent) to control another (a target host) and can be an effective approach for controlling populations of invasive species across broad spatial scales. Climate change, though, is complicating biocontrol, raising concerns that mismatches between how biocontrol agents and their hosts respond to climate change could alter the efficacy of current and future biocontrol programs. In response, a team of RISCC (Regional Invasive Species and Climate Change) Management Network and NE CASC (Climate Adaptation Science Center) researchers has published a new "Management Challenge" that details how climate change impacts the relationship between biocontrol agents and their target hosts and outlines management implications arising from this problem.

Feral swine have recently invaded parts of the Northwest. They have been invading southwestern and central Oregon since 2004 and were first detected in Washington in 2016. Idaho has not seen significant numbers of feral swine, however migrating pigs may pose a threat. The population growth potential of feral swine is closely associated with food availability, which is becoming more abundant year-round due to warmer winter conditions that are linked to climate change. Projected increases in extreme events and average summer temperatures in the region are not expected to negatively impact the success of feral pigs. In response, timely population control measures are necessary to avoid damage to crops, forests, and rangelands.

As climate change reduces the frequency and intensity of killing freezes, tropical plants and animals that once could survive in only a few parts of the U.S. mainland are expanding their ranges northward, a new U.S. Geological Survey-led study has found. The change is likely to result in some temperate zone plant and animal communities found today across the southern U.S. being replaced by tropical communities. These changes will have complex economic, ecological and human health consequences, the study predicts. Some effects are potentially beneficial, such as expanding winter habitat for cold-sensitive manatees and sea turtles; others pose problems, such as the spread of insect-borne human diseases and destructive invasive species.

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.

Provides planting recommendations for present and future conditions using native species adapted to both current and future hardiness zones. 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.

The widely cited “tens rule” in invasion ecology suggests that approximately 10% of established, non-native species will become invasive–or display negative impacts—when introduced to new environments. This study demonstrates that the tens rule is a poor estimate of invasion rates on a global scale. Instead, a ‘twenties rule’ is a better rule of thumb, meaning that roughly 20% of all established, non-native species eventually become invasive

What will the changes in climate mean for the distribution and occurrences of pests? What tools will help in addressing the needs? The Northeastern IPM Center is partnering with other leading organizations on initiatives related to climate change and pests.

Researchers at the University of Massachusetts Amherst recently published a pair of papers that, together, provide the most detailed maps to date of how 144 common invasive plants species will react to 2º C of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions. Together, the papers, published in Diversity and Distributions and BioScience, and the publicly available maps, which track species at the county level, promise to give invasive species managers in the U.S. the tools they need to proactively coordinate their management efforts and adapt now for tomorrow’s warmer climate.

Climate change means new and stronger weeds. In this video, University of Wisconsin-Extension weed specialist Mark Renz shows how climate change will turn some of our existing weeds such as Canada thistle into super weeds. Plus, a look at some new weed threats from the south.

Insects and diseases that are damaging and killing trees across the contiguous United States are reducing the ability of the nation's forests to capture and store climate-changing carbon dioxide, according to a new study. The study – published in the journal Frontiers in Forests and Global Change – found that forests damaged by insects sequestered 69% less carbon than undamaged forests. Those affected by disease sequestered 28% less carbon. In total, the study found that the damage currently being caused by insects and diseases across the contiguous US is reducing the sequestration potential of America’s forests by roughly 50 million tons of carbon dioxide each year – the equivalent of emissions from more than 10 million cars.

The U.S. Department of the Interior has renewed its support for the Northeast Climate Adaptation Science Center (NE CASC) at the University of Massachusetts Amherst with a five-year, $4.5 million commitment as the host campus for its six-member consortium of universities, says center co-director professor Richard Palmer. Scientists affiliated with the center provide federal, state and other agencies with region-specific results of targeted research on the effects of climate change on ecosystems, wildlife, water and other resources. The new agreement continues Interior’s original seven-year, $11 million grant to the NE CASC at UMass Amherst that began in 2011. One of the web-based tools created by the NE CASC is the Regional Invasive Species and Climate Change (RISCC) Management project, which helps invasive species managers through working groups, information-sharing and targeted research.
