Tuesday, March 14, 2023 Session Descriptions (Some session titles and other details subject to change.)

7:45 AM – 8:40 AM

12:30 PM – 1:15 PM

Room: Benson Hall Speaker: Mark Chisholm, Aspen Tree Expert Co., Spokesperson for STIHL Inc This presentation will dig into one of the most difficult yet exciting disciplines in tree care—rigging. Mark will share techniques that he has learned from a lifetime of field work and explain strategies he’s created and refined to meet his needs. You will see, through the help of jobsite pictures and videos, how he approached real world challenges and how he and his crew overcame them by using the best tools of today paired with a little creativity.

Room: Benson Hall Speaker: Mark Chisholm, Aspen Tree Expert Co., Spokesperson for STIHL Inc This presentation will focus on what the climber or bucket operator should know before working with cranes. Too often a crane is brought into the workplace with the expectation that the operator will run the job. It takes a team to work safely and effectively. How to rig, what cut to use, and other tips will be shared using job site photos and videos.

Unique Tree Removal Scenarios

8:40 AM – 9:35 AM

Trees for a Changing Climate in the Midwest

Room: Benson Hall Speaker: Leslie Brandt, Northern Institute of Applied Climate Science Climate change is leading to rising temperatures, altered precipitation regimes, and more intense extreme events in the Midwest. These changes will place stress on trees that communities depend upon for shade, aesthetics, and other benefits. This presentation will highlight the impacts of climate change to urban trees, a framework for assessing vulnerability of these trees, and the results of a study that looked at which common urban trees in the Midwest may be more or less vulnerable to climate change.

Room: Benson Hall Speaker: Richard Hauer, University of Wisconsin The journey anyone of us would walk, maybe sprint, to create an urban forest utopia would likely vary. The end result and path we took might also differ. But maybe during the journey, the mental picture of the many ways trees benefit society might have some rooted agreement. Planning is your journey's friend and an important part of developing the financial wealth that grows with trees. Growing a diverse tree portfolio may likely yield the highest return on the investment. Certainly, selecting the right tree stock is important for long-term yields. The availability of a diverse tree portfolio to select from nurseries and the residual forests we inherit do frame urban forest wealth past, present, and future. Also, as important is how we invest our tree stocks throughout the landscape from local to regional to national and beyond scales. Diversity, equity, and inclusion as an important modern-day construct further plays into creating the urban forest utopia. Inclusion of people that represents the diverse ideas from a community I believe is important for developing an equitable distribution of urban greenspaces. To this utopian end, in this talk we will learn such things as why tree diversity is import; what do we currently know about tree diversity from local to global levels; how might urban green space allocation vary; and what can be done as examples to increase urban green space access. Following this talk is a wealth of speakers from early to emeriti career that will present innovative and provocative ideas to plant the seed of your financial urban forest wealth.

2023 Program Guide

12:30 PM – 1:15 PM

I’m Not Dead Yet! Integrated Approaches to Thoughtful Tree Preservation

Room: BC 411 Speakers: John Kosowski, Harmony Tree Works and Chad Giblin, Trees & Me LLC Using a case study approach, we’ll explore different techniques of tree preservation and tree risk mitigation. Conventional approaches like heavy reduction pruning may lead to accelerated decline in certain trees or species and a shift in expectations is often necessary to better align pruning with a tree life stage. Developmental pruning as a tool to promote tree preservation will also be discussed.

12:30 PM – 1:15 PM

Creating a Culture of Safety

9:35 AM – 10:30 AM

If You Could Build a Diverse Urban Forest Utopia, What Would it Be?

Crane Use for Tree Removals

Room: BC 468 Speaker: David Vincent, Safety Consultant Safety is a solid component of the three-part management team of safety, productivity, and lowered costs. This is based off of three simple ideas: stay safe, stay busy, and do a quality job.

12:30 PM – 1:15 PM

Urban Soils for Urban Trees

Room: CC 125 Speaker: Luke Scheberl, Mid-State Technical College Learn why urban tree managers must consider soil health along with tree health. We will discuss the importance of several soil parameters and how to quickly measure them in the field and their role in tree health. By understanding the soil, we can better understand and care for the trees that grow in it.

12:30 PM – 1:15 PM

Considering Tree Water Stress from a Below Ground Perspective

Room: CC 312 Speaker: Luke McCormack, The Morton Arboretum Drought and waterlogging both cause tree stress and dieback.

However, most observations of tree water stress focus on aboveground responses rather than investigate the drivers of success or failure related to roots belowground. In this session we will present some of the causes and consequences of water stress from a belowground perspective as well as considerations for tree selection and planting to minimize stress when possible.

Tuesday Session Descriptions 12:30 PM – 1:15 PM

Mushroom, Conks, and the “Profiles” of Tree Decay Fungi Room: CC 313 Speaker: Glen Stanosz, University of Wisconsin-Madison Mushrooms and conks can be positive indicators of tree decay. But while tree risk assessment includes consideration of tree “profile”, less consideration is given to fungal “profile”. Learn characteristics for identifying common tree decay fungi, and how different “fungal profiles” can influence decisions regarding evaluation of tree decay.

landscapes. Examples of planting designs will also be shared.

Perennial edibles to be discussed include, Hazelnuts, Aronia Berry – Black Chokeberry, Juneberry, Elderberry, Honeyberry and Cranberry to mention a few.

12:30 PM – 1:15 PM

Communicating Climate Science

Room: CC 331 Speaker: Dave Hanson, Minnesota Department of Transportation From bud break in spring to leaf drop in autumn and during the rest period of winter, trees share clues to their identification. We’ll cover a few individual species from several deciduous tree families and finish with a glimpse at a few coniferous species as well. This presentation will provide insight into seeking identifying clues and interpreting them to aid in tree identification.

Note: Part 2 of this session will be from 1:30pm – 2:15pm.

Room: HC 414 Speaker: Jamie Mosel, Ph.D. Student, Natural Resources Science and Management, University of Minnesota Climate change has widespread impacts on Minnesota's environment, including Minnesota's forests. This session will overview climate change that has been observed in Minnesota, climate change projections for Minnesota's future from MCAP's dynamically downscaled climate projections, and forest impacts along with an emphasis on adaptation. This session will help inform how to communicate climate science and change occurring in Minnesota and in general, especially for those communicating with the public in their professional role, influencing decision makers, or directly making decisions themselves which may involve planning for our future climate.

12:30 PM – 1:15 PM

12:30 PM – 1:15 PM

Room: BC 430 Speaker: Megan O’Neil, Minnesota Department of Natural Resources The Minnesota DNR tracks forest canopy trends from year to year.

This presentation will provide an update on the most common forest health issues in Minnesota, such as eastern larch beetle and spruce budworm. It will also cover some of the less common pests that we saw in 2022.
