General Session
Ice Storms & Tree Damage: Risks & Expectations
Presenter: Dr. Kim Coder, Professor of Tree Biology & Health Care
Warnell School of Forestry & Natural Resources, University of Georgia
Ice storms are a common event which damages trees.  How ice forms on tree surfaces, ice and wind loads, and most common forms of damage will be reviewed.  There are some types of damage which can be minimized by good tree health care practices.

12:00 pm – 1:30 pm
Lunch & Annual Member Business Meeting
Attendees are encouraged to gather for lunch and the annual member business meeting.

1:30 pm – 3:00 pm        Breakout Sessions

1. Climate Variability & Tree Growth
Presenter: Dr. Kim Coder, Professor of Tree Biology & Health Care
Warnell School of Forestry & Natural Resources, University of Georgia

Climate variability has generated a number of tree growth issues and will initiate many more.  There are a number of stress problems which will become more important and more common.  Some climate based constraints will demand more careful tree health care management over the next decades.  A review of recent past and future modeled changes will be highlighted.

2. Threats to Urban Forests
Presenter: Joe Boggs, Assistant Professor, Commercial Horticulture Educator, Department of Entomology/Extension, The Ohio State University Extension

While Asian longhorned beetle (ALB) is potentially the most devastating non-native pest to have ever arrived in North America, it’s not the only tree pest that threatens our urban forests.  Emerald ash borer continues its rampage across Ohio while other borers join in to convert trees into firewood.  Gypsy moth is never completely gone and along with other caterpillars and sawfly larvae supports turfgrass by removing tree canopies.   Scale insects seem to be continually crawling towards unexpected outbreaks.  These are just a few threats to our urban forests that will be covered in this session.

3:00 pm – 3:30 pm        Break

3:30 pm – 5:00 pm        Breakout Sessions

1. Ohio Trees & Native Bees
Presenter: Denise Ellsworth, Program Director, Honey Bee & Native Pollinator Education, Department of Entomology/Extension, The Ohio State University

While trees provide many well-known ecological benefits, the importance of trees as a source of food for bees is sometimes overlooked. Ohio trees can provide food for bees from early spring through late summer, with most tree species in Ohio providing key forage in spring and early summer. This program will emphasize some of the Ohio trees that provide food for bees as well as the natural history and phenology of the bees that rely on trees for food. 

2. Which Pests Matter
Presenter: Joe Boggs, Assistant Professor, Commercial Horticulture Educator,
Department of Entomology/Extension, The Ohio State University Extension

Every tree care business has a unique set of capabilities, customer expectations, and pest management philosophies. This means that each business needs to carefully categorize where to put their tree pest management emphasis.  Determining which category each pest fits is a creative exercise you should undertake each year, to be the most productive and profitable this coming season. This session is designed to help you sort out tree pests and plan your company’s pest management strategy.

8:00 am – 10:00 am
General Session
Diagnosing & Correcting the Physical & Chemical Problems
Encountered in Urban Soil
Presenter: Professor Chris Carlson, Associate Professor, Biology Department,
Kent State University

With 80-90% of all urban tree “stress” originating below ground, it is paramount for competent arborists and urban foresters to be able to assess and treat the most important limiting “physical properties” of urban soil such as soil texture, structure, drainage, compaction, etc. etc.  This informative Soils 101 talk by Professor Carlson will teach you everything you need to know!

10:00 am – 10:30 am     Beverage/Snack Break

10:30 am – 12:00 pm     Breakout Sessions

1. 5 Most Common Mistakes Made in the Landscape –
How Can We “Raise the Bar” and Are You Guilty?

Presenter: Professor Chris Carlson., Associate Professor, Biology Department,
Kent State University

This talk will concentrate on some of the most prevalent errors that continue to be made by landscapers and arborists alike and how we can educate our clients AND “make a difference”. 

2. Pollinator Dynamics & Native Plantings
Presenter: Dr. Anand Persad, Manager Arboriculture & Plant Sciences/Entomologist, The Davey Institute

This study describes the seasonal dynamics observed with soil biological activity, plant biodiversity and (invertebrates) pollinator dynamics in areas populated by native flora after conversion from a mowing-only strategy. Soil biological activity was generally similar in the areas that were still being mowed and those that were newly converted compared to older established areas, except in summer months when soil biological activity was lower in the older established areas.  Plant biodiversity and nectar indices were generally higher with length of time following conversion. The biodiversity of ground dwelling organisms (early colonizers) was lower in mown areas but similar between older and newer converted areas. The above ground invertebrate (pollinators) biodiversity was higher in the older established areas compared to the other areas. Hymenopteran specific surveys however revealed that recently converted areas had higher bee and wasp populations compared to mown areas and the more established plots. Ant populations were highest in the areas that were still being mown. These data describe seasonal dynamics of plants and invertebrates and provide an insight into management strategies that will enrich our invertebrate biodiversity and pollinator populations. 

12:00 pm – 1:00 pm      Lunch

1:00 pm – 5:00 pm        ISA Written Exams

1:00 pm – 3:00 pm        Breakout Sessions

1. Research Project: Survey of Bee Assemblages
Presenter: Bernadette Mach, Graduate Research Assistant, Department of Entomology, University of Kentucky

Mach will review the results of a doctoral research project conducted in the laboratory of Dr. Daniel Potter focusing on a survey of bee assemblages in the urban landscape and investigating neonicotinoid residues in nectar and pollen using field realistic dosages.

2. Be on the Lookout: Cool Caterpillars & Bad Forest Pests
Presenter: Tom Macy, Forest Health Program Administrator, Ohio Department of Natural Resources, Division of Forestry

Most of the insects you encounter in Ohio’s forests pose no threat to our native ecosystems, but there are a few major pests that you need to know!  Tom Macy, Forest Health Program Administrator for the ODNR Division of Forestry, will talk about just a few examples of the great diversity of caterpillars that can be found in Ohio’s forests and how to find them and discuss the major insect and disease pests to be aware of that threaten Ohio’s trees.

State Urban Forestry Assistance: We’re from the Government & We’re Here to Help!
Presenter: Tyler Stevenson, Program Coordinator, Ohio Department of Natural Resources, Division of Forestry

Ohio’s Urban Forestry Assistance Program was created in 1979 within the Ohio Department of Natural Resources, Division of Forestry, to promote trees and other vegetation as tools to enhance the quality of life within our cities, villages, and townships. Our purpose is to provide community officials and allied agencies with the organizational and technical assistance to effectively manage trees and the land on which they grow. Through a statewide network of regional urban foresters, we help communities manage their urban forest resources to meet their local needs. This presentation will provide information and updates on several projects and programs including the Tree Commission Academy, Tree Survival School, Operation Shade, Urban Forest Strike Team, and Tree City USA.
