52nd Annual Minnesota Shade Tree Short Course
March 18-19, 2014
Bethel University, Arden Hills
The 2014 Minnesota Shade Tree Short Course: It’s About Preservation.
"It takes a century to grow a 100-year-old tree." Beloved bumper sticker.
"Preservation," incites thoughts of protecting trees from the wrath of construction and development projects. The 2014 Minnesota Shade Tree Short Course will expand on preservation to include not only saving those at-risk trees, but also municipal budgets and support for tree care and urban forest programs, preserving and building private tree care companies, keeping good personnel and nurturing even better ones, preserving and improving the health of humans, bees, and trees.
"The greatest oaks have been little acorns." Thomas Fuller, 1732
Whether we’re nurturing young trees in the nursery or mature elms in the boulevards, new employees or the faithful current, new companies or storied urban forestry programs, they all had a beginning and it is in our best interest to preserve them. With six diverse general sessions, over 35 concurrent sessions, and a head-spinning educational exhibit area, the annual Minnesota Shade Tree Short Course is your chance to grow, nurture, and preserve. Join us again in 2014…you won’t be disappointed.

No More Maples (for the next 10 years), and Why. Kris Bachtell.
Strong tree diversity is our best protection to help avoid catastrophic losses due to pandemic disease and/or insects. Minnesota's urban landscapes are dominated by three genera: Acer >20%, Picea >18%, Fraxinus >15%. Increased tree diversity is critically important. Learn a new list of trees options for your use.
Saving Trees and Money through Cooperative EAB Management. Jeff Hafner.
As communities manage their ash trees with varying strategies, each management decision affects their neighbor’s results. A recent model predicts greater net benefits for all cities if a centralized strategy is adopted. This presentation explores how this could be done and looks at current examples of environmental cooperation.
When Trees and Winds Collide. Brian Kane.
Arborists prune trees for different reasons; one of the most important is to reduce the risk of failure. Can you really reduce the risk of failure by pruning? There are some competing factors at work, and it’s not as straightforward as you might think.
How We Hurt The Trees We Love: A Caregiver’s Dilemma. Joe Murray.
Perhaps it’s time for us to rollback on our preventative practices until we truly understand how trees do that thing that they do. In this presentation we will examine how trees deal with less than desirable growing situations and how being parsimonious with your “care” may be in the best interest of trees.
The Value of Allergy-free Landscapes. Tom Ogren.
What is allergy-free landscaping, why it is needed, why it may soon be mandated, and how to best do it.
Can Pesticides and Pollinators Coexist? Marla Spivak.
How do we protect trees and other plants from insect damage while protecting beneficial insect pollinators from pesticides? Becoming familiar with the lifestyles and floral preferences of managed honey bees and wild, native bees can help solve this conundrum. Protecting trees or protecting bees does not have to be an either/or decision: We need both!
Improving on What Nature Delivered. Kris Bachtell.
Selective plant breeding for improved traits has occurred for hundreds of years. Many attractive new plant selections host increased hardiness and better resistance to pests and diseases. This lecture addresses useful and improved woody plant selections developed from their “wild form” and describes how these selections are created and perpetuated. This session only offered one time.
Community Gravel Bed Nurseries, from A to Z. Mike Bahe, Gina Hugo, Jacob Ryg.

Count Us In! Volunteer Accuracy in Community Tree Surveys. Nick Bancks.
In 2009 the University of Minnesota’s Forest Resources Department implemented an engagement program that drew solely upon community volunteers. This program sought to help greater Minnesota communities to assess and mitigate the potential damages brought upon by the arrival of emerald ash borer. An evaluation of the community tree surveys was begun in 2011 and has provided some promising preliminary assessment of volunteer accuracy in regards to survey data collection.
Caught with your plants down? Janna Beckerman.

Research Update from the U. Sugar Maple Decline; Effects of Street Reconstruction on Boulevard Trees – 20 years of Information; Elm Performance Trials on Olson Memorial Highway. Dustin Ellis, Ryan Murphy , Jonathan Fillmore.
Three case studies of tree health, survival and performance (respectively). The 2013 sugar maple decline survey was conducted in Saint Paul to determine what if any common factors are associated with the decline in health of sugar and Norway maples. In the years 1993-1994 the Kenwood neighborhood in Minneapolis, MN underwent a total street and utility infrastructure renovation. A study was initiated to determine how these construction activities would affect the existing boulevard trees. Data obtained from the 20-year study is reported. Finally, the Olson Memorial Highway tree trials will explain the research and findings from the long-term elm selection research at Olson Memorial Highway. The study looks at caliper and condition rating data to discover if other hybrid and American elm selections are feasible for use in the urban forest besides the classic Accolade and Princeton elm.
Minnesota’s Native Elm Heritage. Chad Giblin.
