Description

Climate change introduces a new challenge for municipalities as it has the potential to affect areas of forest cover in ways we may not yet completely understand. The recent lack of cold winters, attributed to climate change, has allowed for the mountain pine beetle to wipe out enormous areas of forest land in Canada and the United States. Prolonged drought in California lead to thousands of acres of dead and dying trees in urban and rural areas. Dead and dying trees lead to increased chance of forest fires.

Those who will benefit from attending this symposium include arborists in the municipal and private sectors, other professionals who work with trees and forests, as well as anyone interested in how climate change is impacting trees. Presenters will propose best practices for future tree selection, maintenance and management in light of climate changes.

The goal for the symposium is to lay out a foundation of ideas and experiences, and use those to develop long term action plans to combat the affects of climate change. Along the way we hope to see if we can sort out fact from fiction. By the end of the day we will have a starting point for further debate, some sense of the science available, and initial paths to work on. Our hope is that we can use this material to start focusing on what we have, what we might lose, and how we can work in urban areas to increase the resiliency of our urban forests to enhance their chances of long-term survival.

Instructors

Julian Dunster, PhD | Dunster and Associates (Program Chair and Moderator)

Dr. Julian Dunster has unique academic and professional qualifications. He is a Registered Consulting Arborist, a Registered Professional Forester, and a Registered Professional Planner, and in addition to two degrees in forestry, he holds a Doctorate in Regional Planning and Resource Development. Julian has over thirty years of hands on experience from assignments all over the world, and his innovative work has been recognized with many awards. Julian uses these qualifications and expertise to provide you with practical, science based information, combined with a pragmatic understanding of what will or will not work well.

Climate Change – Where are we in our knowledge and understanding?

The opening presentation will set the stage for the day and establish a baseline context for our conversations about climate change impacts for urban trees and forests in general. Dr. Dunster will explore climate science and trends, and discuss resulting challenges being observed in the field. He will review some of the strategies and materials being worked on in other parts of the world and highlight the resources available already. That will provide a starting point for increased awareness of where we are today as a starting point for the day’s discussion of what arborists and allied professionals can do to adapt to the emerging challenges of climate change.

Drew Zwart, PhD, Plant Pathologist / Physiologist | Bartlett Tree Research Labs

Dr. Drew Zwart is a plant pathologist and physiologist and has been on staff at the Bartlett Tree Research Laboratories for 15 years.  Dr. Zwart earned his PhD at the University of Washington – Center for Urban Horticulture, studying the interaction of plant stress and disease susceptibility. Drew conducts research on plant stress physiology, and plant disease and insect concerns, and provides scientific support throughout Bartlett’s western operations, including Washington, Oregon, and British Columbia. Drew is an ISA-certified arborist and a Registered Consulting Arborist (RCA #630).

Applied Strategies for Climate Change in the Urban Landscape

This presentation will cover several practical, field applicable concepts regarding climate change impacts on the urban forest. Specific case studies and research examples will be provided to illustrate shifting realities in tree management under changing conditions.  Attendees will learn about various stress mitigation options for existing trees, disease and insect concerns for trees under stress, and general practices and concepts to reduce the impacts of a changing climate in the future.

Tom Hinckley, PhD, Emeritus Professor | University of Washington

Dr. Hinckley has been an acting dean, a departmental chair, Director of the Center for Urban Horticulture, and Interim Director of the School. He earned his BA in Biology from Carleton College, and his Ph.D. in Forestry from UW. He has been a faculty member at the University of Missouri-Columbia, Agricultural University of Vienna, and University of Washington. His current research is on interactions between indigenous people, their surrounding forest ecosystems, and the impacts of policies on their use of these ecosystems. His previous research was in plant stress physiology.

Tree Water and Carbon Relations: Current Thinking for the Professional

This presentation will explore how trees die from too little water – offering current thinking and evidence from aspen, ponderosa pine, and pinyon pine dieback in the Rockies and Southwest US.  Management solutions will be discussed.  We’ll also discuss factors involved in understanding whether trees really have greater growth when they are old.

Jason Battles, Urban Forester | Snoqualmie, Washington, USA

Jason Battles is an urban forester focused on proactive planning and adaptive management amidst a rapidly changing climate. He is committed to leading communities in planning for their urban forests to be resilient amidst uncertainty and change.

Adaptive Management for Climate Change in the Urban Forest

A vulnerability assessment and adaptive management are required to sustain and enhance the environmental, economic and social benefits provided by the urban forest amidst a rapidly changing climate. Planning for resistance, resiliency and transition will encourage a vibrant urban forest far into the future. To that end, the completion of a climate change vulnerability assessment and the implementation of 10 adaptive management strategies, approaches and tactics using the Urban Forest Climate Change Response Framework have been adopted and are in practice today by Snoqualmie’s Urban Forestry Program.

Cecil Konijnendijk, Professor of Urban Forestry | University of British Columbia, Canada

Cecil Konijnendijk is a professor of urban forestry at the University of British Columbia, Vancouver, Canada. His research and teaching focus on the multiple roles of trees and other vegetation in urban areas, as well as on governance and planning aspects of urban forestry. Cecil’s work has taken him to different parts of the globe, and he currently holds three visiting professorships at Chinese institutes. He has (co-)authored books like ‘The City and the Forest: the cultural landscape of urban woodland’ and the Routledge Handbook of Urban Forestry.

Urban Trees as Nature-Based Solutions for Grand Challenges

There is increasing awareness about the important contributions trees and other vegetation make to resilient, healthy, and liveable cities. In times of grand challenges such as climate change, continuing urbanization, and declining public health, there is an urgent need for comprehensive urban forestry programs. This presentation discussed our current knowledge on the roles and benefits of urban forests, and ways in which this knowledge has, or can be integrated into urban planning and urban design.
