On June 18, James Urban, FASLA, will present principles from his latest book, Up by Root: Healthy Soils in Trees in the Built Environment, at the Ohio Chapter’s Central Regional Meeting in Columbus. Jim’s presentation will be an all-day workshop that highlights basic principles of soil science and their application in facilitating the growth of healthy trees in built environments.

This workshop includes lectures and field work intended to introduce the underlying scientific principles guiding tree biology and soil-water relations. It is only through a healthy respect for these guiding principles that one can effectively specify, manage, and improve soils, drainage, and trees in the urban landscape. Hands-on sessions will help attendees connect lessons learned during lecture to related field applications. Attendees will be given the opportunity to determine soil texture by feel, pull soil samples with an auger, view a soil profile, and identify visual indicators in the landscape that help determine hidden soil characteristics.

James Urban is a landscape architect with more than 30 years of experience in the field of urban development. Over the past three decades, Jim has routinely dealt with the challenge of planting trees in difficult urban sites. Since 1982, he has researched and tested various methods of tree installation in the urban environment. Jim has developed applications for practicing arborists and landscape architects that include the testing of new urban tree systems and planting concepts, developing new approaches to landscape architectural design, and detailing specifications in the area of trees and urban soils.

A special thanks is extended to The Ohio State University Chadwick Arboretum & Learning Gardens for generously donating the use of their facilities for the workshop.

Invasive woodboring insects pose a severe threat to native trees. European or Asian species are often introduced to North America through the importation of infested solid wood packing material, such as crates and pallets. They usually arrive without the natural enemies which keep them in check in their native lands. Also, North American host plants often lack resistance to these exotic species. While many exotic insects have become established without a significant impact, others have had devastating effects.

The emerald ash borer (EAB), Agrilus planipennis, has killed tens of millions of ash trees in Ohio and other states. First discovered in Michigan in 2002, this native of China and eastern Asia has been detected in 13 states and parts of Canada, and currently occurs in the majority of Ohio’s 88 counties. Larvae of this beetle tunnel under the bark, cutting off the tree’s water and nutrient supplies. At the high population levels seen in North America, infested trees typically die within three years of attack. Signs of infestation include crown dieback, epicormic shoots, D-shaped exit holes, S-shaped tunnels under the bark, and severe woodpecker damage.

The oak splendour beetle, Agrilus biguttatus, is closely related to EAB. This species, native to Europe, the Middle East and North Africa, has not yet been detected in North America. If established, it could become a very serious pest of oak trees. Look for signs of infestation similar to those described for EAB.

The Asian longhorned beetle (ALB), Anoplophora glabripennis, is a threat to a wide range of broadleaf trees, primarily maple, birch, elm and willow. Infestations have been detected in Illinois, New York, New Jersey and Massachusetts. The New York infestation is still under eradication more than a decade after its discovery in 1996. In Massachusetts, thousands of infested trees have been found since the first detection in 2008. In Ohio, two adult beetles were detected in warehouses in 2007 and 2009. While no infestation has been found, these detections demonstrate the potential for the introduction of this pest to Ohio through imported cargo.

ALB larvae bore deep into the wood of their host trees. Signs of infestation include shallow divits in the bark where the eggs are laid (termed oviposition niches), sap seeping from wounds in the tree, dime-sized, perfectly round exit holes, and frass (sawdust-like materials) on the ground and the branches. For more information on ALB, go to www.beetlebusters.info.

Sirex woodwasp, Sirex noctilio, is a pest of pine trees. A native of Europe, Asia and North Africa, is has caused serious damage to plantations of North American pines in the southern hemisphere (South America, South Africa, Australia and New Zealand). First detected in New York in 2004, it has also been found in Pennsylvania, Michigan, Vermont and Canada. In 2009, it was detected in Lake County, Ohio. Signs of infestation include resin beads and drips, round exit holes, cambial staining (by a symbiotic fungus), and tree crowns turning light green to yellow to reddish brown.

Bark and ambrosia beetles, subfamily Scolytinae, are small beetles that may overwhelm tree defenses by aggregating in large numbers on a single tree. Many species attack pines and other conifers, while some, such as the European hardwood ambrosia beetle, Trypodendron domesticum, are pests of broadleaf trees.

Our objective is to detect any infestations as early as possible, to facilitate eradication and other control measures. Each year, we conduct extensive surveys to detect these and other exotic woodboring insects in Ohio. We need your assistance in this effort. Be aware of signs of infestation or unexplained tree decline, and report any suspicious finds to USDA-APHIS-PPQ, the Ohio Department of Agriculture, or your county extension agent. If you have any questions, please email me.

Tree Treks, a class offered at The Holden Arboretum, is for anyone interested in learning about the principal native and introduced landscape trees found in our area. In each session, a different set of 12 trees will be highlighted on a 2-hour walk. Distinguishing characteristics for identifying each species are discussed, along with site adaptations and other horticultural characteristics. Tree Treks is taught by Holden’s president and CEO Clem Hamilton, along with Charles Tubesing, chief horticulturist, and Ethan Johnson, plant records curator. Two instructors lead each session. ISA members can earn CEUs for participation. Sessions are on Saturday mornings 9-11:00 am, twice per month, beginning in May 2010 and running through the first Saturday in October. For more information and to register, please call 440-602-3833 or go to www.holdenarb.org.

Earlier this fall, a White Oak sample from a Franklin County community tested positive for Bacterial Leaf Scorch, Xylella fastidiosa.  Bacterial Leaf Scorch (BLS) is a chronic and eventually fatal disease that displays its most noticeable symptoms in late summer/early fall.  These symptoms include premature leaf browning, marginal necrosis, and defoliation.  The symptoms typically begin at the leaf margins and migrate to the midrib of the leaf.  The following year the tree leafs out normally, but leaves on a few more branches turn prematurely brown in late summer. This will be repeated over a period of years until the entire tree turns prematurely brown and dieback will occur.  Since this can be easily confused with other disorders, it is best to have the suspect tree tested by collecting samples.

Below are three Web sites to help you become more familiar with this disease:

University of Kentucky Cooperative Extension Service
Alan Iskra, Forest Pathologist, USDA Forest Service

BLS is seriously affecting urban forests in New Jersey and Delaware, and because of the positive find in Franklin County, the Ohio Department of Natural Resources (ODNR) Division of Forestry will conduct a statewide BLS survey in late summer/early fall 2010.  Lisa Bowers, the Central Ohio Regional Urban Forester, who is temporarily helping the Forest Health Program, will coordinate this effort.  Because the time to collect leaf samples is quite narrow, Lisa will require help.  The samples that are collected will be sent off for specialized testing.  Sample packaging can be obtained through the ODNR Division of Forestry.  For now, if you have questions about the survey, please Email Lisa Bowers.

Emerald Ash Borer (EAB) University, a collaborative effort of the US Forest Service, Michigan State University, The Ohio State University, and Purdue University, is a series of Webinars bringing you the latest information on EAB.  All Webinars are free although registration is required to access Webinars.  Registration deadline is 5 p.m. on the day before the Webinar. Unless otherwise noted, all Webinars will be at 11 a.m. Eastern Standard Time.
