7:00pm - Neff Lecture Hall — Screening of Hometown Habitat
This is a 90-minute environmental, education documentary focused on showing how and why native plants are critical to the survival and vitality of local ecosystems. Entomologist Doug Tallamy, whose research, books and lectures, on the misuse of non-native plants in landscaping, sound the alarm about habitat and species loss provides the narrative thread throughout Hometown Habitat.
Day One, August 1
Brumbaugh Academic Center (Alumni Hall), Room A-100
8:00am Registration and Continental Breakfast
9:10am Welcome from Mid Atlantic Invasive Plant Council and the Society for Ecological Restoration
9:20am Keynote Speaker: Are “Alien” Plants “Bad”?—Dr. Douglas Tallamy
The expense of fighting introduced plant invasions and the unpopularity of restricting sales of ornamental invasives have motivated several public figures to question the wisdom of continuing to battle invasive plants. After all, they argue, if an introduced plant helps a particular butterfly, bird, or bee, why not embrace it? Using data from several studies, Dr. Tallamy answers this and related questions, showing that we can determine the overall impact of introduced plants on our ecosystems only by comparing what is gained from their use with what is lost when they replace native plant communities. Introduced plants are not the ecological equivalents of the native plants they displace because they do not support the diverse and stable food webs that run our ecosystems.
10:45am Red Spruce Restoration in West Virginia: Successful Partnerships and Successful Projects —Mike Powell, Land Manager, The Nature Conservancy
Successful partnerships have led to successful implementation of projects in West Virginia related to restoration of the red spruce ecosystem. As a member of CASRI (Central Appalachian Spruce Restoration Initiative), The Nature Conservancy in West Virginia is implementing a wide variety of restoration projects by planting trees, thinning hardwood stands for releasing spruce, conserving high priority lands and other strategies to restore and protect this important landscape.
11:15am From Brownfield to Botanic Garden -AJ Ewing
This talk will describe the process of turning a strip-mined brownfield into a living and thriving botanic garden. Restoration efforts and invasive species management will be discussed.
11:45am Chesapeake Bay Landscape Professional: A New Certification Program —Beth Ginter—Advisor, Chesapeake Conservation Landscaping Council
Chesapeake Bay Landscape Professional (CBLP) is a new, voluntary certification program. Through regional collaboration with watershed groups, non-profits, local government, landscape trade organizations, education/training partners, and businesses, CBLP is building a network of professionals to design, install, and maintain sustainable landscapes and stormwater practices throughout the Bay region. Because landscape professionals impact thousands of acres in the Bay watershed, they have a unique opportunity to effect positive change. The certification program includes foundational instruction on conservation practices that incorporate native species, promote biodiversity, and aim to reduce the negative impacts of invasive plants, all in an effort to create landscapes that mimic and support natural systems.
1:30pm Intro to TED Talks
1:40pm TED Talks (6 speakers at about 7 minutes each)
- A Restructuring of Arthropod Communities Following Plant Invasion in the Mid-Atlantic: Evidence for “Green-to-Brown” Shift in Food Webs-- Adam Mitchell
Management of Berberis thunbergii: Effects of Removing a Non-native on Forest Plant Communities and Soil Conditions--Arthur F. Link III
Restoring an Old Growth Urban Forest in the Heart of the New York Botanical Garden-- Jessica Arcate Schuler
Dumbarton Oaks Park, a living landscape: Dumbarton Oaks Park Revealed--Ann Aldrich
Creation of a Wetland Mitigation Bank for Riparian Habitat in Northwestern New Jersey-- Bill Young
Restoring a Blue Heron Rookery on Lower Black River, Ohio--Donna Marie Foster
2:15pm Panel with TED Talk Speakers
3:20pm Biological control of invasive weeds in the eastern U.S. —Dr. Judy Hough-Goldstein
Biological control of weeds involves the deliberate use of living organisms such as insects, mites, nematodes, and fungi to reduce the abundance of a target weed. Typically host-specific natural enemies from the weed’s native range are reunited with the target weed in its introduced range. This talk will review invasive weeds in eastern North America for which there are at least some biocontrol agents established and/or available, and ongoing research that may yield new agents in the future.
3:50pm The Limits of Restoration — Rod Simmons—City of Alexandria, VA
Rod will focus on natural resource management and protection with the practices of “do no harm” and keeping areas natural through Best Management Practices as the overarching goals. The merits of the often related practices of stream bank restoration and mitigation banking; removal and control of non-native invasive species; and pressures to plant after invasive plants are removed will be discussed and qualified. Best Management Practices will also be suggested.
4:30pm Adjourn for Reception
Day Two, August 2
Brumbaugh Academic Center (Alumni Hall), Room A-100
9:00am Mid-Atlantic Invasive Plant Council Business Meeting & SER Business Meeting
10:10am Role of Deer in Expansion of Exotic Plant Species in Eastern Forests -Dr. William J. McShea
White-tailed deer are keystone species that shape forest ecosystems through their selective herbivory and the indirect effects of their behavior across trophic levels (e.g. migratory birds, small mammals, and insects). With the rapid spread of exotic plant species within many eastern deciduous forests there is the strong potential for deer to contribute significantly to the pattern and rate of that spread. Dr. McShea will summarize several recent studies on how deer might facilitate the spread of exotic species in mature deciduous forests of Virginia and Maryland, mostly through the experimental removal of deer or invasive plants.
11:00am Ted Talks (6 speakers at about 7 minutes each)
