KINNUCAN CONTRACTS WITH CITY OF LAKE FOREST, ILLINOIS
Kinnucan Tree Experts has been awarded 2015 tree removal contracts for the City of Lake Forest. In a continued effort to remove diseased Ash, the City of Lake Forest is aggressively removing trees along city parkways. Trees being tagged are either dead, beyond saving or pose specific safety hazards. The City’s long-range plan is to replace about 400 ash trees a year through 2021.
BUR OAK BLIGHT
A serious leaf blight disease on bur oak has been recognized in several Midwestern States, including Illinois. Researchers in Iowa confirmed that this disease is caused by a new, and yet unnamed, species of Tubakia. The disease was named bur oak blight, or BOB for short.
BOB occurs only on bur oaks, primarily on naturally established trees, and especially on mature trees on upland sites that appear to be remnants of savannah forests.
Leaf symptoms typically first appear in late July or August. Infected leaves develop purple-brown lesions along the midvein and major lateral veins on the underside of leaves. Large, wedge-shaped areas of chlorosis and necrosis develop on the leaf blade, and major leaf mortality may occur. The symptoms of wilting and leaf scorch resemble, and have been confused with, symptoms induced by oak wilt. A unique feature of BOB is that some of the killed leaves remain on the tree during the winter (healthy bur oak trees shed all of their leaves in the fall)
Over time, severely affected trees may die. Boosting tree vigor may prolong the life of affected trees and ward off invasion by secondary pests. In preliminary studies, injections of the fungicide propiconazole in late May or early June (prior to leaf symptoms) have reduced symptom development in the fall and the following year.

LB Still A ‘Tree City USA’
For the 19th consecutive year, Lake Bluff has been named a Tree City USA community by the Arbor Day Foundation honoring the Village’s commitment to outstanding community forestry practices.
As part of a family of over 3,400 communities that have received this designation, Lake Bluff has met the following four standards required to become a Tree City USA:
- the operation of a forestry department.
- the protection of trees through a tree preservation ordinance,
- the implementation of a comprehensive community forestry program, and
- a proclamation observing Arbor Day.
In accomplishing one of the standards for Tree City USA status, the Village Board designated Friday, April 24th as Arbor Day in Lake Bluff. This celebration will happen throughout the day in programs at schools and , in particular, in the planting of a tree at Blair Park (355 W, Washington Ave.) at 2:00 p.m.
The benefits of being a Tree City USA are many and are well known to the 135 million Americans living in a Tree City USA. The standards used by the Arbor Day Foundation that distinguish these communities from others help create a framework for an urban or community forestry program. By retaining the Tree City USA designation the Village continues to successfully fulfill one of the goals outlined in the 2016 Strategic Plan, enhancing public and private open spaces, which seeks to achieve the community’s vision of Environmental stewardship, which enhances the natural beauty of the community.
When asked about the environmentally-friendly award, Public Works Superintendent Jake Terlap says, “Being recognized as a Tree City USA for the past 19 years says the Lake Bluff enjoys a quality of life better than most other places and ensures its commitment to its natural environment continues.”
The Tree City USA program is sponsored by the Arbor Day Foundation in cooperation with the National Association of State Foresters and the USDA designation, contact Jake Terlap, Public Works Superikntendent, at 847-735-2310 (tel: 847-735-2310), or email at vlb@lakebluff.org.
KINNUCAN CONTINUES WORK AT STONEBRIDGE DEVELOPMENT, LAKE BLUFF, ILLINOIS
Stonebridge, referred to as Lake Bluff’s Historic Garden Estate, is a new multi-home site to be developed by The Roanoke Group. Once developed, Stonebridge will also include a fully restored Jens Jensen landscape with over 12 acres of gardens. To help with the restoration and preservation, Kinnucan has been busy these last few weeks trimming deadwood, removing hazardous and non-native trees, as well as fertilizing weak trees.
