Each produces different patterns of injury to plants and their ability to cause plant damage varies widely. Many kinds of insects develop by tunneling within trunks and branches of trees and shrubs, including various kinds of beetles, moths, and an odd group of wood boring wasps. Whitney Cranshaw, Colorado State University (D-1 Repeat) A Review of Wood Boring Insects and Their Management* John’s message is always appropriate, timely, and inspiring, so don’t leave early this year!Ī-1. As professionals, we must always follow the science, setting aside practices and methodologies with no proven benefit. Don’t let good intentions get in the way of sound, arboricultural practice. Ball’s message for us this time is a pretty simple one. Besides, he knows us, has mapped the fastest and most efficient way to navigate to Ames from Brookings, SD, and is never afraid to drive in a little snow.
If our goal in 2022 is to reclaim a sense of normalcy in our lives, then inviting John Ball to be our closing general session presenter seemed like the right thing to do. We Always Hurt the Ones We Love: Killing Our Trees with Kindness With over 45 years of experience, Jim is the perfect presenter to tackle this important topic. Tree, root, and crown attributes, along with crown loading, weather, and tree biomechanics are factors that influence tree viability and survivability during severe windstorms. And an understanding of this research will help us discard outdated beliefs, generalizations, anecdotal evidence, and industry myths and misinformation. There has been a proliferation of tree anchorage and biomechanics research in the last decade. With the derecho from the summer of 2020 still fresh in our minds, Jim Flott is here to shed some light on why some trees fail in storm events while others do not. Alonzo will discuss recent work mapping urban air temperature, quantifying cooling from trees, and how urban trees respond to heat. clumps, distributed single trees) influence the magnitude and timing of cooling. It is also well understood that the urban forest cools its surroundings, however, it is still an open question how tree planting site (e.g., street trees, park trees), and configuration (e.g. Previous research tells us that urban areas are 2-3 degrees warmer than neighboring rural areas because vegetation has been replaced by impervious surfaces. The ISU Shade Tree Short Course is pleased to welcome Michael Alonzo, Assistant Professor of Environmental Science at American University, Washington, DC.
