GENERAL SESSIONS and WORKSHOPS
He will review how to use the concepts of normality and
patterns in which plant disorders express themselves…to focus
in on signs and symptoms that will ultimately lead to a proper
diagnosis. Most importantly, Cliff will discuss how you can use
site history information when standard diagnostic practices
have led you to a dead end. Finally, Cliff will demonstrate
how you can use over 1000 images in the Purdue Tree Doctor
smartphone app to make a quick and accurate diagnosis and
obtain research-based management recommendations.
OPENING GENERAL SESSION
Wednesday, February 25, 2015 - 9:30 a.m.
State of the Green Industry
Well folks, we finally wore him down! After pestering him
for years, we finally succeeded in luring Dr. Charles Hall to
Iowa to serve as one of our keynote presenters for the 2015
STSC. According to Charlie, tree growers and landscapers
were among the hardest hit sectors of the green industry
during the Great Recession. BUT, there is evidence of marked
improvement in the green industry marketplace from now
until the next recession (projected in 2018), however, there
still are significant hurdles to overcome. In this session,
Charlie will provide a near-term economic forecast for the
industry and highlight what that means for growers and
landscape and tree care service providers. Be prepared to
leave this session with plans for tweaking your strategic plans
for the upcoming season.
Don’t Just Plant More Trees…Plant Better Trees!
Adopted Iowan and one of our all-time favorite presenters,
Dr. John Ball is back with us in 2015, this time to talk about
planting “better” trees. Young trees at the garden center are
like puppies and kittens…they all look cute and perfect and
you can’t wait to bring them home. But just like our furry
friends who sometimes turn into something unexpected and
unpleasant, unwanted surprises await if you bring home
the wrong tree. As emerald ash borer spreads and begins
causing widespread ash mortality, increased attention will be
paid to replacing thousands of trees. Of course, this action
is commendable, but plant material choices made without
concern for adaptability, longevity, long-term structural
integrity, and/or invasive nuisance potential will always come
back to soil the carpet…as it were.
CLOSING GENERAL SESSION
Thursday, February 26, 2015 - 2:30 p.m.
Using Your Brain and Smartphone to Diagnose Tree
Problems
This is going to be fun! In this closing general session, Dr.
Cliff Sadof will demonstrate how to systematically diagnose
common tree disorders using symptoms, patterns, and signs.
Session A Workshops
A-1. (E-1 Repeat)
Overview of Giant Tree Transplantation Methods
Paul Cox, Environmental Design, Inc.
Tomball, TX
Would you like to know how to successfully move a bur oak
tree that was alive at the time of the American Revolution?

this historic tree on the campus of the University of Michigan
(Ann Arbor).
A-2.
The True Value of Trees
Charlie Hall, Texas A&M University
College Station, TX
In the future, the value proposition for the green industry
must focus on the unique ways in which quality of life is
improved for its customer base. And across all generations
(Boomers, Gen Xer’s, Gen Yer’s, etc.), quality of life is a
“higher order” need important to everyone. Research shows
that there’s no better way to do this than through the daily
use/enjoyment of trees and other plants. Now, all the green
industry has to do is convince consumers that their products
and services are necessities instead of luxuries. In this session,
Charlie will explain just exactly what we need to do to pull
this off!
A-3.
Tree Worker Incidents: The Who, What, How, and Why
John Ball, South Dakota State University
Brookings, SD
Tree worker incidents don’t just happen, they occur because
of factors that aligned before the incident. And the severity of
worker injuries often depends on what happens during the
incident…and afterwards. In this session John will cover how
the most common tree worker incidents occur and show what
you can do to not become next year’s statistic!

living things). The human connection to nature and to trees
specifically can incite community support for the planning,
planting, and management of trees in the landscapes we inhabit
and explore.
From time-tested workmanship in Europe to the American
landscapes, Paddy will discuss the evolution of the
hardscape industry in America. He will stress the importance
of quality products, quality installation, workmanship, and
customer service to help you grow your business and be
more successful.

Nursery Stock – Are You Getting What You Pay For?
Jim Flott, Community Forestry Consultants, Inc.
Spokane, WA
One role that park managers and staff are asked to fill is that
of purchaser and inspector of nursery stock and landscape
trees. Many green industry professionals across the country
tell me they are unable to find quality trees for planting
projects. They say many nursery stock specifications lack
the necessary detail to ensure good stock gets purchased
and installed. Buying high quality nursery stock is all about
writing explicit nursery stock specifications. In this interactive
hand’s-on presentation, Jim will provide superior nursery stock
specifications and give you an opportunity to write your own.
B-3. (E-5 Repeat)
Protecting Ash Trees in Your Communities from
Emerald Ash Borer*
Cliff Sadof, Purdue University
West Lafayette, IN
In this workshop Cliff will share research based information
on how insecticides can be effectively applied to protect ash
trees from the emerald ash borer. His discussion will include
a review of all insecticides labeled for EAB control and
description of how long each will last after application to the
tree. Cliff then will show how his web-based cost calculator
can be used to demonstrate why it makes economic sense to
protect rather than replace trees as they die. Finally, he will
address environmental concerns and the potential use of
biological control in the natural forest.

At the Root – Moving Large Trees Economically
Jim Flott, Community Forestry Consultants, Inc.
Spokane, WA
Bare root transplanting has been used since humans started
walking the earth. It is “the root” of the nursery industry.
The modern demand for immediate effect in the landscape or
retention of existing landscape trees can be met by successful
bare root transplanting of large DBH trees…and it can be
done economically. In this presentation, Jim will review the
process of moving large diameter trees bare root that will
provide you with an avenue of revenue for your business.

The landscape industry is the real “green industry”. Or is it?
As landscape professionals we should have green growing
through our veins, but in the name of landscape design
and installation, are we doing more harm than good? In
this presentation Bruce will identify places where we excel,
where we fail, and where we can be better…from proper
plant choices, to sourcing materials, to water conservation,
and more. Let’s strive to be “greener” for our clients, our

PESTICIDE CONTINUING EDUCATION
The Iowa Pesticide Act provides two options for renewing
commercial pesticide applicator certification. Commercial
and public applicators may choose to renew their certification
by testing once every three years or by attending approved
instructional training each year.
Recertification by training requires participation in two hours
of approved instructional training each year, in each category
in which an applicator is certified. Some programs may be
approved for more than one category and simultaneous credit
hours are possible. Applicators will not be allowed to make
up hours that they missed in a previous year, nor will they be
allowed to carry forward excess credit hours.
The Iowa Department of Agriculture and Land Stewardship
approved the ISU Shade Tree Short Course/INLA Conference
and Trade Show for two hours of recertification credit in
categories 2, 3O, 3OT, and 10. To receive recertification credit,
an applicator must attend workshop C-7 or G-7, “Continuing
Instructional Course for Pesticide Applicators,” and any one
of the following workshops:
