Hi Jason,

Overall, the IRT is okay with the proposed species. However, we have some concerns about including the ash species since they are both susceptible to high mortality from the emerald
ash borer, and we would like to limit volunteer ash to only 1 stem per plot to be counted towards the vegetation success criteria. Please reach out if you have any questions or concerns.

Thank you,

Casey
