MNSTAC Monthly Forums
Monthly forums address issues in urban forestry, arboriculture, and research. Forums are typically held on the third Thursday of the month. To view past presentation, visit the Forum Presentations page.
The December forum will be followed by a potluck, so please bring a delicious dish to pass and share. Tableware, flatware and drinks will be provided. Please also bring non-perishable food items to be donated to Second Harvest in MnSTAC's name.
Date: Thursday, December 20, 2018
Time: 10:00-11:00 AM (Followed by potluck)
Location: Theodore Wirth Chalet in the Wirth Fireplace Room (1301 Theodore Wirth Pkwy, Golden Valley, MN 55422)
Title: Old-growth forest landscapes of the Porcupine Mountains and Sylvania, Michigan
Presenter: Lee E. Frelich, University of Minnesota Center for Forest Ecology
Description: Landscape-scale old-growth forest remnants have many features not commonly seen in smaller remnants. These include patterns in forest stand development and succession caused by wind and fire disturbances, unexpected large-scale patterns in species composition that arise from neighborhood effects between adjacent trees, untrammeled relationships between land and water, and last but not least, many occurrences of very old and very large trees.
Date: Thursday, November 15, 2018
Time: 10:00-11:00 AM
Location: Minnesota Pollution Control Agency - Room 200/201
Title: Ginkgo and Ginkgo Seeds: Public Nuisance or New Urban Food Product?
Presenter: Ryan Murphy, University of Minnesota, Department of Forest Resources
Description: Ginkgo seed, the forbidden fruit – or at least the stinky fruit that isn’t really a fruit but actually a naked seed. You may love them or hate them, but if 250 million years has anything to say about it, ginkgo seems to be here to stay. Most urban tree fanatics can wax poetic about ginkgo’s many positive attributes, but when is the last time you heard someone speak endearingly of the seeds? Come hear about the Midwest's oldest native tree and discover how it could be our next urban food product at this month’s MnSTAC forum.

Date: Thursday, September 20, 2018
Time: 10:00 am - 12:00 pm
Venue: St. Louis Park Rec Center, Banquet Room, 3700 Monterey Drive, St. Louis Park 55416.
Forum Information (Starting at 10:00 am)
Topic: Probably More Than You Thought You'd Ever Want To Know About Tree Roots and Root Systems.
Presenter: Gary Johnson, University of Minnesota.
Description: Roots, the Rodney Dangerfields of the plant world..."they get no respect!" They're the 50% of a tree's biomass that exist largely undetected and rarely understood. Today, we'll review how they form, what is typical, what's abnormal and dysfunctional, when they grow, where they grow, when they eat, when they sleep, and most importantly, what can we do to encourage them to grow vigorously and healthy. As the roots go, so goes the shoots.

What's Going On With Minnesota's Trees This Spring/Summer? A panel discussion with tree care professionals
Date & Time: Thursday, June 21, 10:00 AM -11:00 AM (immediately following the 8-10 a.m. MnSTAC board meeting)
Venue: Newell Park Recreation Building, Saint Paul (corner of Pierce-Butler Road and Fairview Avenue)
Description: After a long, relentless winter, we were all looking forward to spring. Didn't happen. April was the fourth coldest April in MN history and as depressing as it was to us, it was equally tough on trees. Along with that unusual chain of weather events, there has been a lot of random and pretty disturbing damage to trees that we are all trying to figure out what the next steps might be. Join a panel of tree health professionals from the public and private tree care worlds to discuss some ideas of what went on, what else might happen, and what we might do next.
1.0 ISA ceus will be awarded to certified arborists.
What Trees Will We Be Pruning, Tending To and Sitting Under In 2050?

Date & Time: Thursday, May 17, 10:00 AM -11:00 AM
Venue: St. Louis Park Rec Center - Gallery Room, 3700 Monterey Drive St. Louis Park, MN 55416
Forum Presenters: Chad Giblin and Gary Johnson, University of Minnesota, Urban Forestry Outreach Research and Extension Lab and Nursery
Description: It takes 30-40 years for the trees we're planting today to reach a size where they are actually contributing to the quality of lives in urban areas: providing shade, blocking cold winds, increasing property values. There are a couple of tricks to predicting which trees will be here in 2050 or later. One, what can be planted now that will be excelling in 30-40 years, and Two, what kind of maintenance practices will those trees require to reach those contributory sizes? Join us to speculate about the future of urban forestry in the upper Midwest and bring your crystal balls.
Transit Stop Environments and Waiting Time Perception: Impacts of Trees, Traffic Exposure, and Polluted Air
Date & Time: Thursday, April 19, 10:00 AM -11:00 AM
Venue: Minneapolis Park and Recreation Board Headquarters, Board Room (second floor). 2117 West River Road, Mpls.
Forum Presenter: Andrew Guthrie, University of Minnesota's Humphrey School of Public Affairs.
Description: When you're sitting at a transit stop station, whether it's for the blue line, the green line or a bus, do you get fidgety and grumpy after a few minutes of endless traffic streaming by you, along with the collateral exhaust pollution filling your lungs and tearing up your eyes? Maybe the problem isn't the long wait or the noise or the pollution, maybe it's simply because there's not enough green surrounding you.
Andrew Guthrie was part of a research team that studied that exact phenomena and found that for waits longer than 5 min, perceptible pollution and exposure to traffic led to significant overestimates of waiting time. Riders waiting at stops with dense, mature tree cover, however, significantly underestimated their waiting times. The effect of dense, mature tree cover is strong enough to compensate for the effects of both air pollution and traffic awareness.
Andy Guthrie specializes in transit planning research, with interests including regional accessibility, improved performance measures, transit service and facility design, and transit-oriented development in the Humphrey School of Public Affairs. He takes special interest in the resurgence of rail transit and the social equity implications of transportation.
Join us for a very interesting session and a different perspective on the values of the urban forest. Maybe you intuitively knew this all along and just needed some evidence to confirm your gut feeling. Or maybe you're just tired of slogging through the cold and snow and could use a jolt of camaraderie with some fellow tree lovers and mass transit users. Join us for a little coffee and some light (I mean, very light) refreshments. The forum is open to all.
MnSTAC Forum at Bailey Nursery
Date: Thursday, February 15, 2018.
Venue: Bailey Nursery, 1325 Bailey Road, Saint Paul, MN 55119
Gordon Bailey Training Room in the HR building, east across the parking lot from Bailey's main office. Park in front of the HR building or on the east side.
Time: 10:00-11:00 for the forum. A tour of the cold storage facility to follow the forum.
Topic: New Trees and Shrubs...for the Next Few Years.
Forum Presenters: Brenda Wickenhauser - Bailey Nursery, and Doug Danielsen, Bachman's Nursery.
Description: Spring is (almost) here! Only three (okay, maybe four) more months and we'll be sinking our shovels into the fresh soil, planting trees and shrubs with visions of color and canopy in our heads. Join Brenda and Doug to get their take on some the best trees and shrubs for the next few years in our Midwestern landscapes. And if you have time - I'd recommend making the time - stick around for a guided tour of the cold storage facility at Bailey's and their system for storing and shipping plants all over the country. If you like trees, it's like a visit to Candy Land.
Urban Tree Canopy Mapping and Measuring using High-Resolution Remotely Sensed Data
Presenter: Trevor Host, University of Minnesota
Urban tree canopy is a critical and rapidly changing component of the city landscape. Tree canopy provides benefits that range from ecological to economic to aesthetic. Obtaining landscape scale information on the status of tree canopy is costly and time-consuming on the ground but can be completed much faster and more cost-effectively from the air. In this research, we used airborne remotely sensed data to precisely observe the abundance, condition, and changing status of urban tree canopy. High-resolution optical imagery and lidar datasets were used in combination to update and assess change of urban tree canopy in the seven county Twin Cities Metropolitan Area. Object-based image segmentation using eCognition software was able to automate detection of isolated tree crowns.

Note on parking:
All people coming to MPCA offices in Saint Paul should look at: https://www.pca.state.mn.us/sites/default/files/stpaulmap.pdf
The front desk tells me that folks should jot down their car license plate number and it will take just a minute or two for them to get past them, and down to the lower level.
