TTNM Conference - Glyphosate: Things to Think About

Join us for a candid and practical presentation of today’s most contentious (and commonly used) herbicide: glyphosate. Dr. Bowling will discuss emerging issues after many municipalities banned glyphosate use and how trees are affected in our landscapes. If you’re confused about what the big deal is with glyphosate, why it is being banned, what the alternatives are, what is the difference between glyphosate and glufosinate, or how to even pronounce these words, this is the session for you. Prepare to learn a lot and be entertained throughout.

TTNM Conference - Drought Conditions: Planning & Adapting

Dave DuBois, the state climatologist for New Mexico, will talk about climate change in New Mexico and especially its relation to urban landscapes in our region. Dr. Dubois, also Director of the New Mexico Climate Center and Associate College Professor at New Mexico State University, will give an update on the environmental indicators of climate change in the state and where to find related resources. Dr. DuBois says we have been seeing an increase in temperature of about 0.7°F per decade over the past 50 years across most of New Mexico. He will review the latest on climate change indicators across the state that include temperatures, drought, rainfall, extreme precipitation, winds, wildfires, growing season, and air quality.

TTNM Conference - Healthy Soils Support Healthy Community Trees

Join us in learning why soil is one of the most important parts of maintaining a viable and long-lived community tree canopy. Tree health and risk is heavily influenced by the health and quality of the soil surrounding it. Soil provides trees with essential nutrients, water, support, gas exchange, and more, but these services are limited when soil is compromised (for example, through pollution, compaction, and limited root volume). In this webinar, you will learn about the biological and arboricultural basis for managing soils of community trees, including understanding compaction, salinity, and soil crusting and ways to ameliorate it, soil organic matter and its application, water harvesting into the soil below the pavement, protection during construction, and recommended soil volumes. This session supports sustainable urban development projects and landscapes.

Holly Campbell (Speaker) - University of Georgia Warnell School of Forestry and Natural Resources, Public Service Assistant

Ms. Campbell focuses on community forestry and wildland fire outreach education and undergraduate instruction. Ms. Campbell is also part of the faculty team of a new Warnell degree program in Community Forestry and Arboriculture, which launched in Fall 2019. Among other interests in community forestry, Ms. Campbell seeks to educate the public and professionals about soil protection during construction, increased soil volume to urban trees, and the importance of urban soil health and quality to support tree health. Ms. Campbell has a BSA in Horticulture and an MS in Forest Resources, where she focused on soil science research. Prior to being an educator, Ms. Campbell was a landscape gardener for over 10 years, focusing on soil health, wildlife-attracting gardens, and perennial fruit production.

TTNM Conference - Soil Geomorphology for Arborists

“Soils are the diverse baseline ecological components of terrestrial plant growth. We will explore some of the tensions that arborists and other land resource professionals encounter in their attempts to grow good trees and other plants. These tensions include diversity in the soil landscape: the tasks of solving resource assessment conundra, analysis and assessment: dealing with some common mythologies attached to the understanding of soil resource properties and soil behavior/capabilities, compacted and stratified soils: the difficulties and pleasures of negotiating differences between construction professionals and horticulturally sensitive individuals tasked with growing plants, if you build it, will they grow there?: performing natural resource magic in a physical world, and case studies of some large projects will be presented and lightly discussed. Soils and soil processes will be "venerated."

David Kelley (Speaker) - Kelley & Associates Environmental Sciences, Inc., President

David Kelley is a plant and soil scientist who has been involved in wildlands ecological assessment and habitat restoration, as well as agricultural and urban soil projects, for over forty years. He picked up degrees in zoology (B.S. 1970) and botany (M.S. 1974) at Texas Tech University, and almost finished a Ph.D. in plant physiology and soil science (Ph. Cand. 1977) at the University of California, Davis, on his way to starting his consulting firm in 1981 in Davis. Although he maintains that he has never had a career-track job, he has managed to spend time as a roughneck in the West Texas oilfields; teach upper-division Plant Physiology at UC Davis and Wildland Ecology at Humboldt State University; grow and export a few tons of asparagus from Peru; design and permit what was at the time the largest wetland mitigation project in the U.S. west of the Mississippi (Kachituli Oxbow in western Yolo County); testify and provide consulting services as an expert on wetlands, soils, trees, and agricultural issues in Hong Kong, West Virginia, Hawaii, Belize, Mexico, and throughout California; and enjoy some time spent hunting and swimming across most of the U.S. Along the way, he has served as an officer of the Soil and Water Conservation Society, the Society for Range Management, Professional Soil Scientists Association of California, the California Native Grasslands Association, and other professional organizations, and he has had the privilege and pleasure of teaching way too many short courses on soils, wetlands, agriculture, and trees to resource professionals in several states. He brings a real and long-standing interest in the conservation and management of natural resources and the complex realities of trees and soils to our Think Trees New Mexico conference this year.
