Upcoming NAISMA Monthly Webinars

Healthy Trees, Healthy Cities

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.

Chuck has been with the University of Georgia for 21 years where his work focuses on invasive species and information technology. He has a B.S. and M.S in Computer Science. Websites that he designed have been featured twice in Science Magazine and have received over 1.7 billion hits since 2002. Chuck developed the infrastructure behind Bugwood Images which runs the and websites. Recently, Chuck has focused on mapping invasive species and tools for Early Detection and Rapid Response using EDDMapS and smartphone applications. He has led the development of 73 smartphone applications including the first apps for the U.S. Forest Service and National Park Service. He was appointed to the National Invasive Species Advisory Council in 2013 and elected as Chair in 2017. Chuck has been an invited speaker at over 300 regional and national conferences and co-authored over 62 journal articles and outreach publications. Chuck is the current president of the North American Invasive Species Management Association.

Dr. Hallett (B.S. UW- Madison, M.S. and Ph.D. UNH) has spent his career studying tree and forest health in the northeastern U.S., working towards earlier detection of tree stress caused by acid rain, exotic insects and diseases. In 2009 he shifted his research focus from ex-urban forests to urban ecosystems. Currently he is working with a team that has developed an urban tree health assessment app in order to get more eyes on trees nationwide. When Rich is not deeply engaged in urban forestry and the science of tree health you may find him judging Timbersports competitions around the world, downhill skiing amongst the trees, or sea kayaking.

Best Management Practices for Pesticide Applications

July 21, 1 p.m. CT

Presented by: Sandra McDonald, Mountain Pest West

To use pesticides legally and efficaciously the first step is to identify the pest. Then determine your pest management strategy. If a pesticide or mixture of pesticides is the best choice, the pest manager must read, understand and follow the pesticide product’s label. This presentation will “walk-through” a number of key label statements. Emphasis will be placed on the importance of assuring the site is allowed on the label, environmental hazard statements, mixing compatibility and jar tests, and sprayer clean-up procedures.

Sandra McDonald portrait with plant backgroundSandra McDonald founded Mountain West PEST (Pesticide Education & Safety Training) in 2009. Prior to establishing Mountain West PEST, Sandra was the Environmental and Pesticide Education Specialist at Colorado State University. She worked for thirteen (13) years at Colorado State University where she was involved in specialty crop pesticide research, in addition to her role as a pesticide safety educator. Sandra also has extensive teaching experiences in pesticide safety, pesticide applicator exposure, pest management and pesticides in the environment. She is an active in a number of professional organizations including the American Association of Pesticide Safety Educators (AAPSE), the Western Society of Weed Science (WSWS), and the Rocky Mountain Agribusiness Association (RMAA). She is currently the president of the WSWS.

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.”
