Other Events


Arbor day was celebrated this year with the planting of a Princeton elm in front of the municipal building on Mercer street. The tree was planted in honor of Bernie Miller, a well-known and long-time citizen of Princeton. Bernie Miller served as mayor of Princeton Township and more recently retired from his elected position on Council, an office he held since Princeton consolidated in 2012. The event was organized by the Princeton Shade Tree Commission. Mr. Miller has been a strong advocate for street trees, parks, and open spaces in Princeton and served as the liaison on the Shade tree Commission for many years.
Like Mr. Miller, the Princeton elm  (Ulmus americana 'Princeton' ) has an illustrious history in Princeton. It is a cultivar of the American Elm and was developed in 1922 by Princeton's nurseryman William Flemer for its beauty but was later found to have a moderate resistance to the devasting Dutch Elm disease that wiped out most American elm trees. Many Princeton elms planted along Washington road survived the infestation and their upright branches form a beautiful cathedral-like canopy. 










Thanks to its recent “life-of-the-tree” adoption by Bartlett Tree Experts, the signature ash tree behind the War Memorial bench, at the intersection of Nassau and Mercer Streets, was injected with a protective insecticide, emamectin benzoate, on June 14, 2017.

First, former municipal arborist Lorraine Konopka measured the circumference of the tree to determine the correct amount of insecticide.

Then, Jason Bond, a plant health care specialist at Bartlett, drilled 12 entry points along the base of the tree, inserted small metal tubes, and pumped the insecticide into the tree. The whole procedure lasted 15 minutes. 











Lorraine Konopka, Princeton's former municipal arborist, was among the more than 40 talented scientists, parents, and community members who volunteered their time to wow Littlebrook Elementary School children during the 8th annual Science Expo on May 18, 2017. Set up beneath the cherry trees near the school's arcade, Ms. Konopka's table featured the Lorax (a Dr. Seuss character encouraging sustainability), fruiting ash tree branches, and vials containing the dreaded ash tree borer and its larvae. PSTC members Janet Stern and Pat Hyatt assisted Ms. Konopka throughout the afternoon.
