Hey MG’s: We’ve developed the Tree Track with you in mind! This is your chance to dive into a multi-layered learning experience that’s all about the life of our Minnesota trees. Under the umbrella of Climate Change, you will learn more about your urban tree canopy, the aging of trees, growing precipitation rates in southern Minnesota, diseases in northern Minnesota, - and what do we do about it. Join us for an amazing two days of fun and facts!

    Difficult conversations: to treat or not to treat
    Gary Johnson
    Let's face it, sometimes a tree problem is just not worth putting a lot of effort into treating it.  Maybe the tree's health is too far gone?  Maybe it's so dangerous that it really needs an excuse to be removed? Maybe the timing for treatment has passed and anything you do is a waste of time and money? Maybe there is no treatment? And maybe, just maybe, the problem really isn't a problem. In this session, we will look at several instances that challenge quick diagnoses and treatment recommendations, and hopefully, hopefully we'll all leave the room with a better perspective on when problems should and can be treated.

    Recent impacts on tree health from excessive precipitation and shorter winters
    Brian Schwingle, Minnesota DNR Forest Health Specialist
    Much of Minnesota has experienced increasing levels of precipitation in spring and summer for the last several years. The end result has been an unprecedented outbreak of a native leaf disease, bur oak blight. Increased precipitation has caused other problems to our forests and trees too. These tree health problems will be described along with proposed remedies. Besides more rain, winters have gotten shorter, which are at least partly responsible for an 18-year-long outbreak of a native bark beetle, the eastern larch beetle. This beetle has now destroyed over 220 square miles of Minnesota's forests.

    Historic and future native tree species in Minnesota
    Lee Frelich
    Tree ranges follow climate. At various times since the last glaciation, the Twin Cities have had boreal forest, temperate deciduous forest, and prairie vegetation, with large changes in the native tree species list. Looking at a future with increasing temperatures this area will gain a lot of tree species that have the edges of their ranges just to our south. We will look at some of these 'neo-native' tree species.

    12:30-1:25 LUNCH

    1:30 - 2:20 p.m. Meet in MACMILLAN B/D AUDITORIUM

    Shade Tree Garden Tour: Overview of tree selection based on shade quality, growth rate, total height, pollinator appeal
    Jeff Johnson
    We will be walking to the Pillsbury Shade Tree Exhibit to discuss the shade quality, growth rate, total height, pollinator appeal of some commonly recommended and not so common shade trees.  We will be visiting some unusual shade trees along the way.  We will be leaving the Oswald Visitor Center, walking through the DeVos Home Demonstration Garden, Nelson Shrub Rose Garden, Dayton Wildflower Garden to the Pillsbury Shade Tree Exhibit and back.

    2:30 - 3:20 p.m. MACMILLAN B/D AUDITORIUM
    Developing Engaging Urban Forestry Curriculum for Kids

    Monica Randazzo
    Engaging youth in the environmental sciences is an important way to create a culture of stewardship and develop multi-generational connections. In this presentation, I will discuss the various ways in which I have approached developing tree-science education for different age groups. I will use examples from working with the Youth Engagement in Arboriculture summer tree-climbing camp, developing lessons and activities for visiting student groups, as well as doing school visits around the Twin Cities Metro Area.
