Introduction to Aquaponics Nicholas Renner Founder, Integrated Symbiotics Aquaponics is a food production method that combines aquaculture (raising freshwater fish) with hydroponics (soilless agriculture) in a symbiotic environment. This novel approach to agriculture can be used in unconventional areas, and saves 90% more water than conventional gardening. These systems work by recirculating fish waste through grow bed systems, with bacteria converting fish waste into nitrates, which are used by the plants to grow. Clean water is then recirculated back to the aquaculture system. In this class you will learn how to plan, design, build and maintain an aquaponics system. Bring your lunch and something to drink.

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).

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 Bastian Regional Technical Advisor, Davey Tree Expert Company/The Care of Trees 40

Mark Highland Spring Courses 2017 at the Morris Arboretum 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 CEUs for landscape architects. Thursday, March 30 Fee: $135 (includes lunch) 9 a.m.–4 p.m.

Caring for Mature Trees Dr. Rex Bastian Regional Technical Advisor, Davey Tree Expert Company/The Care of Trees Robert Wells Associate Director, Arboriculture Outreach Learn how to care for mature 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 school of arboriculture Register Now!

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.

The Barnes Endowed Lecture - “The Critical Role of Plants in the Urban Landscape” Dr. Ari Novy Executive Director, U.S. Botanic Garden, Washington, D.C. Engaging urban populations in important environmental issues is critical for creating beautiful, healthy cities. In this lecture, Dr. Ari Novy will explore using ecology and agriculture to teach people about the importance of plants. As more and more people around the world move into cities, fewer and fewer of them have regular contact with natural or agricultural landscapes. Yet, our success and survival as a society relies on our ability to effectively steward the open spaces in our cities as well as those that are often far away from our urban centers. Learn more about what Dr. Ari Novy and the staff at the U.S. Botanic Garden have done to teach the public about the aesthetic, cultural, economic, therapeutic, and ecological importance of plants 43 to the well-being of humankind. This lecture will take place in the Widener Visitor Center. The Barnes Endowed Lecture is presented annually in memory of Laura L. Barnes, founder of the Barnes Foundation Arboretum.

“Approaching Sustainability” Dr. John Francis National Geographic Explorer and Environmental Educator Beginning with his journey on foot across the Americas, Dr. Francis will speak about his transformation from an environmental activist to environmental practitioner and how his and our own journeys might lead us closer to sustainability. Dr. Francis began his work in 1971, when after witnessing an oil spill in San Francisco Bay, he stopped using motorized vehicles and took a vow of silence lasting 17 years. He earned three degrees including a doctorate in land resources from the Nelson Institute for Environmental Studies at the University of Wisconsin-Madison. The founder of Planetwalk, an environmental awareness organization, he ended his silence on Earth Day 1990, telling the assembled crowd, “Environment is about how we treat each other.” He served as project manager for the United States Coast Guard Oil Pollution Act of 1990 and authored Planetwalker: 17-Years of Silence, 22-Years of Walking, and Ragged Edge of Silence: Finding Peace in a Noisy World, both published by National Geographic Books. This lecture is being presented in partnership with Temple University Ambler, and will be held at the Ambler Campus Learning Center Auditorium.
