Save Our Ash Trees

The Indiana Parks Alliance is working with Indiana State Parks and Nature Preserves to protect 100 mature, seed producing ash trees across the state to save this native species for the future.

The Emerald Ash Borer is an invasive insect that has killed tens of millions of ash trees since it first came to the U.S. in 2002. As of March 2017, EAB has been documented in all 92 counties in Indiana. Within the next ten years, 95% of all ash trees in Indiana will have been lost!

Ash trees compose 15-20% of our Indiana forests, and they have both environmental and economic benefits.

The Division of Nature Preserves has already treated 100 trees in 2017 at Portland Arch NP, Big Walnut NP, Pedestal Rock NP, Rocky Hollow-Falls Canyon NP, Mounds State Park, Shrader-Weaver NP, Coffee Bayou NP, Kramer Woods NP, and Hemmer Woods NP.

Join The Campaign!
100% of every donation will go to the Save Our Ash Trees program. The average cost of treating one mature ash tree is $200, so we have set our campaign goal at $20,000. We need your help!

Ash trees have been located and targeted for treatment at Turkey Run State Park, Shades State Park, McCormick’s Creek State Park, Harmonie State Park, Shrader-Weaver Nature Preserve, and Big Walnut Nature Preserve. The insecticide being used is Emamectin Benzoate, which is not a neonicotinoid, and is safe for pollinators like honey bees.

IPA is excited to report the award of a $20,000 grant from the Dr. Laura Hare Charitable Trust for the Save Our Ash Trees campaign. The grant will be used for treatment of ash trees remaining on at least 7 state parks and state nature preserves. While the $20,000 grant is the big news, it’s important not to forget the other donations.  Many IPA members donated anywhere from $35 to $1,000.  Several local state park and nature preserves friends groups, including Friends of McCormick’s Creek, Ft. Harrison, and Limberlost, made major donations.  Indiana Native Plant and Wildflower Society also made a major donation.  All of those donations have made this campaign a great success.  With all of these donations we have raised a total of $28,770 (as of Feb. 13).  Thanks to all who donated and please continue to donate so that we can save additional trees, and re-treat trees in 2-3 years.
