    Field Trips and Conservation-focused Garden Tour

    Select one of five exciting excursions in the region! All trips feature plant species at the leading or trailing edges of their natural ranges. Our trip leaders include Dr. Eric Doucette (State Botanist of Maine and President of Josselyn Botanical Society of Maine), Matt Charpentier (Field Botanist, Oxbow Associates and Past President, Librarian of NEBS); Dr. Robert Wernerehl (State Botanist of Massachusetts and Vice President of NEBS), Dan Jaffe Wilder (Director of Applied Ecology, Norcross Wildlife Foundation), Heather McCargo (Founder, Wild Seed Project), and Melissa Cullina (VP of Plants and Science at Coastal Maine Botanical Gardens and President of NEBS).

      Plenary Speakers

      Dr. Jesse Bellemare

      Title: Climate change, plant conservation, and the future flora of New England

      Abstract: Climate change is emerging as a top threat to biodiversity in the 21st century with alarming projections of increasing extinction rates and the disruption of ecological communities. Against this backdrop, botanists focusing on New England are likely to see many unsettling changes in the region’s flora in the future, some of which are already emerging, such as changes in phenology and retreating distributions of northern species. While many botanists are already well-accustomed to monitoring and protecting rare and declining plant species in the region’s native flora, one novel challenge going forward will be to develop a conceptual framework for guiding our approach to range-shifting plant species that may enter New England from regions to the south as a result of climate change. This talk will explore these complex ecological and ethical issues, and highlight several examples of range-shifting plant species establishing in New England via human introduction that may have conservation value in the future.

      Dr. Bethany Bradley

      Title: Native versus introduced plants: Climate-driven range shifts and comparative risks to ecosystems

      Abstract: There is broad concern that the range shifts of global flora and fauna will not keep up with climate change, increasing the likelihood of population declines and extinctions. Many populations of introduced species already have advantages over native species, including widespread human-aided dispersal and release from natural enemies. But do introduced species also have an advantage with climate change? In this presentation, I will review observed and potential range shifts for native and introduced species globally, with a focus on plants. I will show that introduced species are expanding their ranges orders of magnitude faster than native species, reflecting both traits that enable rapid spread and ongoing human-mediated introduction. I will discuss the implications of these different rates of spread for both invasive species policies and restoration strategies that support the persistence of New England plants.

      Dr. Jay Wason

      Title: Acclimation, adaptation, and migration: Maine’s forests and climate change

      Abstract: Dr. Jay Wason leads a research group at the University of Maine’s School of Forest Resources, investigating how forests respond to climate-induced stressors like heatwaves, flooding, and drought. In this talk, he will explore the current state of Maine’s forests and present new research on their responses to ongoing climate change. Drawing from his recent studies, Dr. Wason will discuss the capacity of native tree species to acclimate and adapt to shifting environmental conditions, as well as the potential for tree migration to track suitable habitats. This talk will highlight the challenges and opportunities for conserving Maine’s iconic forests in an era of rapid environmental change.
