Managing Forest Fragments
Ken LeRoy - Arborist, John B. Ward & Co Tree Experts

Fragmentation of natural areas due to urbanization results in isolated forest fragments. Cut off by highways, rail lines, commercial and residential developments, these patches of green infrastructure surrounded by the built environment are often neglected. These disturbed landscapes can be managed to develop a healthier, safer, functioning forest. The potential of the earth to support optimum tree growth and carbon sequestration can be realized by following basic forestry practices: vine control; preferred species selection; thinning for fewer more efficient trees; soil health; wildlife enhancement; and, carving out access for people. All the earth is a garden and requires tending. Come and learn how to grow good woods in our community forests. This course carries 5.75 CEUs for ISA certified arborists (S=2, P=1.75, M=2).

A morning lecture and demonstration will be followed by an afternoon session of supervised, hands-on pruning. Please bring your pruning tools and dress appropriately for the weather. This course carries 4.5 CEUs for ISA certified arborists (S=1.5, P=2, M=1).

Reading the Land through Climate Change: Local Plant Adaptation Past, Present, and Future
Mark Demitroff - Adjunct Professor, Stockton University

Ancient climate change profoundly influenced the character of the flora that we cherish today. Local ecosystems and the native plants that depend upon them owe much of their inheritance to cold, nonglacial processes that characterized much of the last 2.5 million years. We will reconstruct local past environments through geology, climatology, and plants to help develop a long-term view of ever-changing plant adaptation. We will then be better able to preserve and manage habitat in the
future. Mark is a board director for the U.S. Permafrost Association and for South Jersey Culture and History Center. He lectures internationally and publishes on ancient climate change and permafrost, and Quaternary Science. A native of the Pinelands, Mark consults and provides expert witness testimony as a New Jersey Certified Tree Expert. This course carries 5.75 CEUs for ISA certified arborists (S=3, P=1, M=1.75).

Fundamentals of Soil Science
Dr. Rex Bastion - Regional Technical Advisor, Davey Tree Expert Company/The Care of Trees
Mark Highland - Founder, The Organic Mechanics Soil Company

We have always known that soil is extremely important for growing plants. It is estimated that 80% of the problems we see with urban trees originate from improper soil conditions. Until recently we primarily considered the chemical and physical components of soil like texture, pH, compaction, and nutrient levels. The latest findings show that the living components of soil are at least as important as the chemical parameters. With the help of soil bacteria, fungi, protozoans, and other living
creatures, we can create greener landscapes and reduce our reliance on petroleum-based fertilizers and chemicals. This course carries 5.75 CEUs for ISA certified arborists (S=3.75, P=1, M=1),
and 6 CEUs for landscape architects.

Caring for Mature Trees
Dr. Rex Bastion - Regional Technical Advisor, Davey Tree Expert Company/The Care of Trees
Robert Wells - Associate Director, Arboriculture Outreach

Learn how to care for aging trees and the changes that occur as trees age Trees, like all living things, survive through the transfer of energy. This transfer occurs both within the tree itself, as well as between the tree and its environment. Far from being static processes, however, energy relations are highly dynamic, constantly changing as trees age, decline, and die. The astute arborist should be aware of these changes, so as to provide the best advice and management recommendations to his or
her clients for the care of older trees in the built landscape. Rex joined The Care of Trees in 1989 after receiving his Ph.D. from Iowa State University, majoring in Entomology. He is a Regional Technical Advisor with the Davey Tree Expert Co./The Care of Trees, with emphasis on education and training, public relations, and diagnostics. He is an International Society of Arboriculture Board Certified Master Arborist and currently serves on the ISA Board Certified Master Arborist Test. This course
carries 5.75 CEUs for ISA certified arborists (S=3, P=.75 M=2).

Tree Appraisal Workshop
James Korman -Consulting Arborist

Assigning a fair monetary value to individual trees is an important skill for municipal and consulting arborists as well as anyone who is responsible for managing a property, park, or arboretum. This workshop focuses on the theory and practice of the appraisal of woody plants. James will review the various approaches to valuation that are currently available and how to determine which is the most suitable choice. The primary focus will be on the Cost Approach and the Trunk Formula Methodology for determining monetary value. The outdoor component of the workshop involves simulated appraisals on several trees in the Arboretum with hands-on instruction. An analysis of each problem will follow. The instructional material follows the 9th edition of the Guide for Plant Appraisal (International Society of Arboriculture) as prepared by the Council of Tree and Landscape Appraisers (CTLA) and reflects current understanding and practice in arboriculture. Come prepared to be outside. This course carries 6.75 CEUs for ISA certified arborists (S=2, P=2.5, M=2.25).

Emerald Ash Borer: Controlling the Spread
Joel Spies - President, Rainbow Treecare Scientific Advancements
Shannon Herbst - Mid-Atlantic Territory Manager, Rainbow Treecare Scientific Advancements

The spread of emerald ash borer (EAB) into Eastern Pennsylvania and New Jersey is a major challenge and opportunity for Philadelphia area arborists to preserve worthwhile ash trees in the landscapes we manage. One of the most efficient and environmentally safe methods of pesticide application is microinjection technology that allows you to apply systemic products to targeted trees in a responsible manner. Microinjection is also an effective way to deliver a host of other fungicides and plant health care products. A key factor in achieving safe and effective applications is a thorough understanding of the injection techniques and products that are available. This one-day workshop will provide you with a background in microinjection and an overview of all of the available products and equipment on the market. You will have a hands-on opportunity to practice an application on an ash tree. This course carries 5.75 CEUs for ISA certified arborists (S=2, P=1.75, M=2).
