Saving the Ash Trees In Gompers Park- data collection

Help the Gompers Park Advisory Council save our ash trees by making a donation to help with the cost of treatment.

Yesterday members of GPAC, the North River Commission and the Save Your Ash Coalition, identified, measured and assessed the overall health of the ash trees in Gompers Park as a preparatory step towards treating the trees for the emerald ash borer. With treatment, infested trees still posessing the majority of their leaves in June, and those that appear completely healthy, have a very good chance of surviving the emerald ash borer invasion that has been sweeping the United States. Without treatment, ALL ash trees will become infested and die.

Starting last summer, thansk to the efforts of the Save Your Ash Coalition, the Park District began allowing local park councils to arrange for the private treatment of ash trees to save them from emerald ash borer infestation and certain death.

Horner Park was the first to arrange for treatment- 66 of their ashes were treated, and today, 65 are still alive!

Now, Gompers Park has begin the process of getting our ash trees treated. The first step, undertaken this past Saturday, June 7, was data collection and assessment.

We counted a total of 95 ash trees – a combination of green ash, white ash, and purple ash – mostly in Big Gomps (Gompers Park north of Foster Ave.).

Of those 95 trees, 22 were dead- these were a combination of several large, older trees in Big Gomps with circumferences between 80 and 120 inches, and many smaller trees in both Big and Little Gomps.

Of the 69 living ash trees we counted, we determined that 47 are treatable. Twenty-two of the trees, while still alive, are not worth treating because they are already seriously invested with the emerald ash borer, and have less than 50 percent of their expected foliage. Many have less than 20 percent of their epected leaves.

The sizes of the 47 trees that are treatable range from 5 inches diameter (of the trunk at chest height) to 30 inches diameter. For reference, the three large shade trees in the Gompers Park playground – all very healthy ash trees as of this writing – are about 15-16 inches diameter.

Treatment of trees (using an injected chemical into the base of the tree trunk) is estimated to cost between $6 and $8 per inch diameter. So the playground trees will be about $90 to $128 each. But treatment last three years, at which point it needs to be applied again.
