Ryan- I haven't done enough coring in the eastern hardwoods to know how common this is, but it is very common out west in a variety of conifers...this happened enough in firs, that USFS workers were often referred to as Piss Fir Willies...as a PFW, doing Continuous Forest Inventory, I'd cored many a tree early in my career and the 10 minute experience as you suggest, rings true as an open cavity, draining by gravity pressure...I have experienced, like Lee's comment, those under pressure that are pretty nearly explosive...when trees like these are hit by lightning, they really bust up (as opposed to just vertical scarring or splitting). -Don

From: [email protected] To: [email protected] Hi all: My technicians just called in- they are coring red oaks in a mature forest near Dayton Ohio, and they report that three trees in a row have, at some point in the process squirted, vinegary liquid from the borer bit for ~ 10 minutes each. 3/3= 100% albeit a small sampling. So, what gives. My answer was that there must be some fissure in the canopy of the tree that is letting water into a rot pocket and they are draining the pocket with the borer. Alternative explanations? thanks ryan _________________________________________________________________ Get your vacation photos on your phone! http://windowsliveformobile.com/en-us/photos/default.aspx?&OCID=0809TL-HM --~--~---------~--~----~------------~-------~--~----~ Eastern Native Tree Society http://www.nativetreesociety.org Send email to [email protected] Visit this group at http://groups.google.com/group/entstrees?hl=en To unsubscribe send email to [email protected] -~----------~----~----~----~------~----~------~--~---
