Inoculation

Location: The Esplanade
Date photo taken: 20 June 2013

Back in January, this blog featured the green tree tags that mark healthy ash tree specimens around the city. Recently the tagged trees along the Esplanade received treatment via these small injectors to help them stave off infestation by Emerald Ash Borers, an invasive and highly destructive insect. Once the trees had been treated, their bark was marked by a bright green painted dot.
