The minutes of the February meeting were distributed and approved.
Don Hostetter introduced our newest member to the commission, Dick Mortensen, who is a retired professor of microbiology.
Emerald Ash Borer Plan revision – Several minor changes were made to our EAB Response Plan that was adopted in 2006. The commission felt that it is still accurate and functional for guiding the village’s actions, obligations, etc. to the impending threat to ash trees with only a few areas that needed to be clarified and updated. Jeremy King feels we should state that it is our intent to be active, to periodically monitor infestation levels and record findings, to work with residents, etc. Dick Mortensen asked who will make a determination of “distressed” for any given tree. For street trees, that would likely be the street department. Regis emphasized that we refer homeowners to an expert to determine infestation of trees on their personal property. Michelle asked specifically when an infested ash tree will be removed – when the ash borer is first detected, when the tree is fully infested, or when the tree is dead. Michelle said the village web page should refer citizens to a step-by-step process for their personal ash trees. Council was notified in 2006 that additional funding would most likely be necessary for tree removal, chipping, and replanting of street trees, but should be re-notified at this time.
On February 20, Lynne Kishler found emergence holes in two ash trees on North Prospect St. Urban Forester Lisa Bowers affirmed the presence of the EAB and bark was shaved off to uncover S-shaped galleries. However, no larvae were found at this site. These trees, on the east side of North Prospect Street across from the fire station, had previously been slated for removal because of problems with the roots and the slope of the sidewalk. The trees showed other signs of stress as well. Since that time, Don Pheneger, Don Hostetter, and Lynne have examined nearly all street ash trees in the uptown area, as well as on Kilkenny and Ballymore (where all street trees are ash planted by the developer). Also examined were trees in Fanchion Lewis Park (the front area), Bryn Du, and Newark-Granville Rd. No additional emergence holes were discovered; however, our investigation will serve as a baseline for future damage.
Jeremy reported that Denison has treated six ash trees this year for the first time. Of the approximately 45 surveyed ash trees, very few are in pedestrian areas. Twenty are relatively new plantings around newer buildings. Their strategy is to plant new trees to succeed the ashes. The campus’s wooded areas have many ash trees.
Don Hostetter has set Wednesday, April 4th at 7 pm for Paul Kanninen, USDA, and Lisa Bowers to conduct a program for residents interested in learning more about the Emerald Ash Borer and the Asian Longhorn Beetle. It will be held at the Bryn Du mansion.
Opera House Park – Weather permitting, there is a tentative start date of the first part of April for the trees and shrubs along the east side to be removed.
Memorial Tree Program – With Don Pheneger’s assistance, Regis has looked at memorial tree programs in other communities and has found a great variety of options. It depends on what we want to include in our program, what we will offer, how much we will ask for the trees, how they will be marked, etc. Jeremy added that Denison’s is patterned after the memorial tree program at Dawes Arboretum. Denison asks for a donation of $1000 for a new planting, and guarantees the tree for ten years. Jim feels strongly we should keep our donation to an affordable amount.
Tree City USA will be held this year in Dublin on April 18th from 9 am to 2 pm.
Michelle reported that discussion has just begun in council regarding dividing up the capital fund expenditures between groups requesting money.
Jeremy reported that Denison’s Tree and Landscape Advisory Board is evaluating landscape plans for two buildings -Chamberlin and Mitchell Center. They are finalizing a schedule of events to celebrate Arbor Day, hoping to coordinate a tree planting at Spring Valley Park with the opening of their arboretum and a memorial tree planting on campus.
Linda reported that the flower sale will be May 12-13.
The next meeting will be April 10th at 7 pm.
