Green and White ash trees have been killed by the hundreds of thousands by Emerald ash borer in the Pittsburgh area. This project identifies trees which have been injected with TreeAge in 2011 and again in 2014 by GPS coordinates and small numbered aluminum tags (1 through 158). These tags are above head level and are facing trails or roadways.

Ash trees with aluminum tags in the 650 through 699 are lingering ash which have not been treated.

All of these trees are very important to the eventual restoration of their respective species. less ↑
