Soil Ecology and Trees Day

Registration ends ends Oct 02
This day-long workshop will expose or re-expose arborists to the process of assessing planting sites or existing conditions to best determine species to plant or treatment of existing trees. Soils have been manipulated by humans intentionally and unintentionally through agricultural practices, construction and landfilling practices (Anthrosols). Arborists are increasingly needing to understand and treat these sites as we continue to develop into agricultural lands and infill our urban areas. Specific case studies will be covered after a review of soil physical and chemical properties. There will be an in-field element to better understand Anthrosols and other soil conditions trees face in the Western States. The objective of this workshop is to provide the attending arborist the ability to recognize site conditions that may necessitate a soils scientist consultant, to know what soils tests need to be run, to provide an understanding of the soils analysis for treatment of the site, and to know how to best choose tree species for the analyzed conditions.
Note: We will be walking to the outdoor field site – looking at trees along the way. Wear comfortable shoes.

Dr Yamina Pressler, Exploring the formation and function of anthropogenic soils.
Dr. Yamina Pressler is an Assistant Professor of Soil Science and Restoration Ecology at Cal Poly, San Luis Obispo where she leads the Coastal Soil Horizons & Ecology Lab (C-SHEL). Her research focuses on soil ecology, formation, and biodiversity to inform soil restoration and stewardship in California coastal bioregions. Yamina is also an educator and science communicator committed to collective soil conservation and care. She received a Ph.D. in Ecology from Colorado State University, and B.S. in Environmental Management from Cal Poly, San Luis Obispo. Yamina was a Postdoctoral Research Associate at Texas A&M University, prior to joining the faculty at Cal Poly in 2019.
Dr Stewart Wilson, Fire and Soil in the Pyrocene
Stewart Wilson is an assistant professor of soil resources at California Polytechnic State University, San Luis Obispo. Dr. Wilson is a soil and geospatial scientist whose research broadly focuses on how soils form and are distributed across the landscape, and how soil formation and the spatial distribution of soils influences biogeochemical cycling, land management and carbon dynamics. Dr. Wilson conducts research in soil genesis and mineralogy, predictive mapping, soil biogeochemistry and soil health. Dr. Wilson holds a B.S. in soil science from Cal Poly Humboldt, a M.S. and Ph.D. in soils and biogeochemistry and a M.A. in geography (GIS and modeling), all from UC Davis. Dr. Wilson teaches courses in introductory soil science, spatial analysis, mapping and soil genesis and morphology, and leads the Soil Geoinformatics and Biogeochemistry Lab at Cal Poly-SLO.
David Kelley, Why Trees Grow Where They Do: Assessing the Soil Landscape
David Kelley has been a consultant on soils and land use, arboriculture, fire and flood damages, environmental resource issues, and rangeland and agricultural matters for over 40 years. His projects have included large-scale commercial development and ecological restoration projects, assessments of tree failures and tree-soil problems, rangeland and farmland damage and value assessments, land use and disaster damage analyses, and mitigation and planning for projects throughout California, the U.S., and internationally. He has developed and teaches courses in soil geomorphology, soils of perennials in ag and environmental systems, tree biology, wetlands, and land useissues for private- and public-sector clients. He taught plant physiology in the Botany Department at UC Davis and wildland ecology in the Forestry and Wildland Resources Department at Cal Poly Humboldt. His small consulting firm,K&AES, Inc., continues to benefit from its associations with arborists, agronomists, ecologists, and other naturalresource professionals across the state and internationally, and with attorneys, professors, engineers, landscape architects, and other professionals.
