2021 Agenda

Day 1 – September 14

Focus on drought, tree selection and adaptability, and soil moisture.

1:00 PM- 1:10 PM | Welcome & Introduction
Heidi Lakics | Urban Forestry Consultant & Contract Manager, City of Eugene

1:10 PM – 1:50 PM | Drought Implications For Tree Resilience Against Pests
Because of climate change, drought stress is increasingly becoming a primary cause of tree damage and reduces resilience to insects and diseases. Dr. Christine Buhl, state forest entomologist at the Oregon Department of Forestry, will discuss how drought damages trees and influences pests and will highlight the diagnosis of major pests that follow drought.

Christine Buhl | State Forest Entomologist, Oregon Department of Forestry

1:50 PM – 2:20 PM | Trees and the Rain Shadow: Managing Trees Along the Cascades (Hood River)
The arid rain shadow of the east Oregon Cascades creates a unique and hostile environment for trees. While it is beautiful to live at the threshold of ecotones and species distribution, it also creates a hostile environment for trees on the edge of their native range. This presentation will focus on the impact of rainfall in regards to the urban forest and urban interface current insect and disease issues.

Tyler Roth | Owner, Gorge Tree Surgeon

2:20 PM – 2:50 PM | Plants of the Dry Side – Searching for Climate-forward Plants
With predictions for Portland’s regional climate being dryer and warmer over the next 30 years where will our climate adapted plants come from. We will explore plant distribution and climate models as tools to predict where we should be looking for plants. Along with the talk we will review a recent plant collection trip and what we chose to collect and why.

Martin Nicholson | Curator, Hoyt Arboretum, Portland Parks & Recreation

2:50 PM – 3:10 PM | Break

3:10 PM – 3:40 PM | Nursery Selections for Urban Forestry Resilience
Today’s catastrophic weather events confirm what climate scientists have been predicting for decades. A general trend toward a hotter, drier climate will be accompanied by temperature extremes and severe weather events including heavy rains and flooding, windstorms, ice storms, wildfires and periods of severe drought. Current thinking suggests that future urban forest health depends on planting a diverse mix of adaptable, resilient species and cultivars, both native and introduced. Learn how growers and researchers are working to identify climate-resilient species, and how we are working to select, hybridize and grow trees that will survive and thrive in the face of an uncertain future climate.

Nancy Buley | Director of Communications, J. Frank Schmidt & Son Co.

3:40 PM – 4:20 PM | Drought Resiliency for Urban Forests
Droughts test urban ecosystems and catalyze innovations and adaptations. Let’s dig in to the science of how drought impacts urban trees to inform urban forest management practices for short and long term plant health care. Learn marketing and management strategies to implement now, and how to build a monitoring schedule for tree populations on a landscape level to assess efficacy. 
Ruth Williams | Board Certified Master Arborist, Tree Risk Assessment Qualified, Treecology Consulting Group LLC

4:20 PM – 5:00 PM | Soil Moisture: The Most Important Factor for Young Tree Survival in UF
The most common cause of death of newly planted urban trees is under- or over-watering. Typical guidance on tree watering does not address actual watering efficiency, such as: How much water evaporates, runs off, is lost via percolation, or consumed by weeds instead of the tree? Without this information, the amount of water applied to trees means little. Wei Zhang, PhD, will discuss soil moisture, how water becomes available to most tree species, and other factors, which are critical to trees’ survival.

Wei Zhang, Ph.D. | Co-Founder/Co-Owner Zynnovation LLC

Day 2 – September 15

Focus on storm preparedness, ice storm lessons, tree survival in green infrastructure, and using Tree Plotter Inventory to plan for climate fluctuations.

8:00 AM – 8:10 AM | Welcome & Introduction
Lauren Grand | Assistant Professor, Extension Forester, Oregon State University, Forestry & Natural Resources Extension – Lane County

8:10 AM – 8:35 AM | Storm-Proofing Your Urban Forest: Are You Ready for the Next Natural Disaster?
Oregon’s urban forests saw a roller-coaster of a year in 2020, from erratic weather to unprecedented wildfires – the trees experienced a lot of stress. When managing our urban forests, urban forestry professionals often think about best practices such as right-tree right place and adhering to proper pruning standards. But we can’t stop there. Simply planting the right trees in the right places and making sure they get the right care won’t cut it when unexpected disasters arise. This presentation explores the ”six Rs” of preparing for and responding to natural disasters that can make or break the urban forest, or urban forestry programs.

Paul D. Ries, Ed.D. | Senior Instructor and Director, Graduate Certificate in Urban Forestry, Oregon State University

8:40 AM – 9:20 AM | Preparing and Responding to Storms – Emergency Management
This session will cover the February 12th ice storm response in Salem, the implementation of GIS programs including Survey123, Arc GIS Field Maps & Arc GIS Workforce for tracking information for FEMA and the management of service requests and hazardous trees. It will cover strategies for tree replacements and maintenance as it relates to being prepared for future storm events and discuss climate change and how to manage urban forest to adapt to longer summer drought periods.

Milan Davis | Urban Forester, City of Salem

9:20 AM – 9:45 PM | Break

9:50 AM – 10:30 AM | The Time to Plot is Now
The Oregon Division of Forestry recently implemented a statewide web and mobile tree inventory mapping system for cities and towns to use at no cost. There are numerous ways the statewide tree inventory mapping system supports communities of any size in managing trees in relation to drought, climate, resiliency, and flooding. Cities can track specific information such as irrigation use, trees used in green infrastructure design, and health related drought or flooding impacts. Dashboard charts and reports make it fast and simple to assess vulnerability to pests/diseases and water management issues and present this information to the public or decision makers. A brief interactive demonstration of the platform will be provided as an introduction to the tools and their ease of use. Learn how it easily it works for GIS/GPS tree inventory data collection, reporting, analysis, planning, and more.

Tony Mecum
| Urban Forester, Grants Pass

10:30 AM – 11:10 AM | Where Trees and Water Meet in the Public Rights of Way: An evolution of practice regarding trees in stormwater management facilities
The planting of trees in stormwater facilities in rights-of-way is a relatively common practice that involves more complexity than meets the eye. The thinking on, the practices of how and what to plant in these frequently soggy, though often bone-dry, locations has evolved significantly over the past two decades within the Bureau of Environmental Services at the City of Portland. This presentation aims to share how our best understanding of the functional processes, species tolerances, and design details involved has changed over time based on our experiences with hundreds of installations across the city. It also aspires to open the conversation with allied professionals on how we might better achieve stormwater management through the planting of more trees in urban areas, particularly in the context of a changing climate.

Kris Hikari | Green Stormwater Resource Manager, Watershed Revegetation Program

11:10 AM – 12:00 PM | Green Stormwater Infrastructure
By using plants to clean up and mitigate the effects of stormwater, Green Stormwater Infrastructures (GSIs) are being developed to replace the conventional grey infrastructures for stormwater treatment. However, plants often fail before becoming established because the plants undergo constant stresses: either too wet (during storms) or too dry (in between storms). By design, green infrastructures are flooded during storms. Also, by design, the very porous growth media should drain and dry out quickly. The extreme variations in soil moisture makes it very hard for any plants to survive. This presentation will discuss the interaction between the stormwater and trees as well as other plants in the GSIs and will offer solutions that to ease the extreme variations in soil moisture with the use of the abundant stormwater.
