Upcoming NAISMA Monthly Webinars

Federal Deregulation of Emerald Ash Borer and Programs Going Forward

April 21, 1 p.m. CT

Presented by: Herb Bolton, National Policy Manager, USDA, and Leigh Greenwood, Forest Health Program Director, The Nature Conservancy

This webinar will focus on the changes that invasive species managers should know about stemming from the January 2021 federal deregulation of emerald ash borer (EAB). Herb Bolton, USDA APHIS, will share information about the federal EAB Program and will explain what was in place prior to deregulation, and what actions and programs will continue now that the deregulation has been completed. Leigh Greenwood, The Nature Conservancy, will describe how states and other organizations are imposing local regulations, shifting management, and adapting their prevention efforts in response to deregulation. Leigh will also explain the Don’t Move Firewood outreach program and will share the resources available to managers to spread the word and prevent the spread of invasive species in firewood.

Herb Bolton serves as a National Policy Manager at the U.S. Department of Agriculture (USDA), Animal & Plant Health Inspection Service, Plant Protection and Quarantine, Emergency and Domestic Programs in Riverdale, MD. His program responsibilities include policy management for the Emerald Ash Borer and Biological Control programs. He is a Board Certified Entomologist with an M.S. degree in entomology from Rutgers – The State University, and a Ph.D. in entomology from the University of Florida.

Leigh Greenwood has worked for The Nature Conservancy since December 2007. Her work focuses on bringing multiple stakeholders together to achieve common goals in Forest Health, including: managing the Don’t Move Firewood campaign, convening the Continental Dialogue on Non-native Forest Insects and Diseases, and working to improve the international biosecurity measures in place for solid wood packaging. Leigh’s leadership of the Don’t Move Firewood campaign has led to its being widely regarded as one of the most innovative public outreach arms of The Nature Conservancy. Leigh earned her B.A. in Biology at Williams College and her M.S. in Wildlife Biology at the University of Montana in Missoula, where she studied the intersection of native wildlife and invasive plants.

Tree Health Monitoring for Invasive Pests

June 16, 1 p.m. CT

Presented by: Rachel Holmes, The Nature Conservancy; Michelle Johnson, USFS; Chuck Bargeron, UGA; Dr. Richard Hallett, Research Ecologist, USDA Forest Service, NYC Urban Field Station

New tree-killing insects and diseases are often spotted first in cities, making tree health monitoring a priority not only for these trees themselves, but for the health of the entire North American forest ecosystem. Seven years ago, The Nature Conservancy, USDA Forest Service, and University of Georgia partnered on the development of a scientifically rigorous, non-stressor specific tree health monitoring protocol called Healthy Trees, Healthy Cities. The protocol is non-stressor specific making it a critical tool for the early detection of new, unknown insects or diseases. Furthermore, the protocol and an associated smart phone application (app) and web-based “dashboard” leverage the expertise of civic scientists and professionals alike, increasing public awareness of tree health issues. Learn about the methodology, new tools and updated training resources, as well as examples of where these tools have been used to improve tree health efforts in cities.

Rachel Holmes is the Urban Forestry Strategist for The Nature Conservancy’s Cities Program. She supports urban forestry projects and programs in the North America Region by providing strategic and technical support to Conservancy colleagues engaging in urban greening, especially through forestry. She also leads three national initiatives with the USDA Forest Service and represents the Conservancy as the Vice Chair of the Sustainable Urban Forest Coalition. Prior to joining the Conservancy, Rachel served as an urban forester and Volunteer Coordinator for the State of Connecticut’s Department of Energy and Environmental Protection, and designed and led urban forestry workforce development programming for Groundwork Bridgeport and Solar Youth, both in Connecticut. Rachel holds a Bachelor of Science from Rutgers University, a Master of Divinity from the Yale Divinity School and a Master of Forestry from the Yale School of Forestry and Environmental Studies.

Michelle Johnson is a Research Ecologist with the Northern Research Station of the USDA Forest Service. She is based at the NYC Urban Field Station in Bayside, Queens. Her research spans social and natural sciences and focuses broadly on social-ecological systems, urban natural resources stewardship, and urban forestry. Current projects focus on urban forest patch governance, tree stewardship and health relationships, and changes in stewardship over time. Dr. Johnson is a co-lead on the Stewardship Mapping and Assessment Project (STEW-MAP). Her toolkit includes spatial analysis, qualitative and quantitative social science, and field ecology methods. Dr. Johnson holds a B.S. in Biology from Eckerd College, a M.S. in Natural Resource Planning from the University of Vermont, and a PhD in Ecology and Environmental Sciences from the University of Maine.

Racial Equity & Environmentalism

August 18, 1 p.m. CT

Presented by: August M. Ball, Cream City Conservation. 

Join August M. Ball, founder, and CEO of Cream City Conservation as she outlines how compounded disparities impact communities of color in every corner of society.  Be it socio-economic, political, educational, health, etc. communities of color remain disproportionately impacted by environmental hazards yet grossly under-represented in spaces that hold key decision-making power related to conservation and sustainability. This presentation will provide the history of the construction of race, (a key component in driving these inequities), while also examining environmental policies that have had a layered impact on the environmental movement and contributed to the racial homogeneity we see today.  The goal of this presentation is to help participants understand why these inequities exist and develop shared language for how to discuss these issues and interrogate the intricate relationship between race and institutional outcomes.

August M. Ball, founder of Cream City Conservation. Her two-prong social enterprise helps organizations institute strategies that attract and retain top talent from diverse candidate pools, making their workforce stronger, smarter and their programs more sustainable and relevant. Simultaneously, Cream City Conservation Corps cultivates the next generation of land stewards by engaging traditionally underrepresented youth in environmental career pathways. With over 15 years of program management and design experience, August has connected thousands of youth and young adults to hands-on service to public lands, outdoor recreation and first time employment experiences.

USGS and USFWS collaborative project to conduct a national horizon scan for organisms in trade

November 17, 1 p.m. CT

Presented by: Wes Daniels, USGS

 Invasive species are one of the greatest threats to the United States (U.S.) biodiversity and have cost the U.S. over $120 billion in damages each year (Pimental et al. 2005). The impacts of invasive species range in size and scope from small-scale and localized up to broad shifts in ecosystem function and can influence economically essential species and those of conservation concern alike. The consequences of an invasion include not only degradation of the natural ecosystem but also economic repercussions and effects on human and wildlife health in the invaded areas.

The focus of this project is to conduct a global horizon scan to help identify alien vertebrate species within the Organisms in Trade Pathway at greatest risk of entering the country, establishing populations, and becoming invasive in the U.S. Our work will address arrival, establishment, and impact via consideration of propagule pressure, climatic similarity to occupied range, and prior invasion history of the focal species and its relatives, respectively.
The approach we are proposing will review a large number (ten of thousands) of Organisms in Trade (OIT) to identify species that that have a high risk of invasiveness in the U.S. By starting with a larger pool of species (opposed to the Roy et al. screening process started with 329 species) there is a great opportunity to recognize new species with no known invasion history. Through a process of filtering the project team will reduce the OIT to a manageable number of higher risk species (~500) based a species potential to arrive, establish, spread, and cause harm (impacts). The project team will also evaluate species with unknown natural histories based on phylogenetic and expert knowledge. We will use a largely automated initial screening, to be followed by expert elicitation and further species prioritization. The development of watch lists can guide early detection efforts, can help inform resource managers, and can provide a repeatable tool for early detection and rapid response efforts (EDRR). In addition, watch list(s) can be used to prioritize evaluations under the injurious Wildlife Provisions of the Lacey Act.”
