Thanks for these remarks.
About the ranger event, i still don't understand how these termites would help with the kitin tunnels. The bark is not a soil, it's solid vegetal fibers. I can't believe the bark will collapse to close the tunnels unless termites have eaten the entire bark itself above the tunnel, plus this collapse would be a big shock, leading to something similar as earthquake (barkquake ? :p)
