    Cavities and honeybees online on June 20th, 11AM-1PM Eastern US time.

    Attached is a flyer for enthusiasts of free-living honeybees. I'll be talking about cavity formation and two other presenters will be discussing bee biology and the woodworking to produce "natural" settings to encourage honeybee hives. The latter is more controversial than one might think, but...

    Wood types and tree care

    I'm curious, when you are making decisions on pruning, cabling, etc., do you consider whether or not heartwood is present in the branch or stem? Would you approach treatment of a black locust as you would a paper birch? No trick question here, no wrong answers (dangerous to say, I know.) Thanks!

    Alex Shigo anniversary

    I just wanted to publicly express my gratitude to the work and friendship of Alex Shigo who died from a fall at his lake home in Barrington, NH on October 6, 2006. Al may not have gotten all of the details perfectly right, every time, but his expertise and prescience still impresses the heck...

    Amherst MA Arbor Day observance

    I'll be speaking at the Amherst Arbor Day observance on Friday of this week, April28. Details here. Mostly about the effect of size on tree biology. Late notice to y'all, I know. I was thinking that this would be just with a few of the local civilians, but apparently not. No charge, no...

    Alex Shigo anniversary

    Just a little reminder that this is the anniversary of Dr. Shigo's accidental death in 2006 in Barrington, NH. After careers as a musician and a US Forest Service researcher, he became an entrepeneurial author and book publisher from about 1986 forward. His landmark works A New Tree Biology and...

    New CODIT article

    No, I know this won't interest many, but it might interest a few. Hugh Morris and team (including Francis Schwarze) have a new research article on compartmentalization linked here. I provided one of the peer reviews to the editor who then asked me to write a commentary in response for the same...

    Starting new threads

    May I respectfully suggest that when folks start new threads, they title the thread with just a little bit of information. Simply calling a thread "Help" or "Confused" is not very helpful to me. How about "chipper handling" or "Brands of boots" or "leaf spots on Rhododendron". This is helpful...

    Who fertilizes the forest?

    I have a recent non-technical article on the topic at: http://www.nrs.fs.fed.us/pubs/50463. The trade magazine mangled a sentence or two, but I think the sense is clear. As the article is about 4 MB, I thought I'd just post the link and not the text itself.

    The comment period opened on November 30, 2015 and closes on January 4, 2016 for the draft ANSI standard. Send comments to Bob Rouse at TCIA, rrouse@tcia.org. My apologies if this has been posted elsewhere on Treebuzz. This is a pretty important document with the goal to: "unify and take...

    How do you recognize a node?

    What does a practicing arborist recognize as a node on a tree stem or branch? Botanically, defining a node is simple and based on primary growth. In the seedling or newly emerging shoot, growth is from cells produced at the tip by the apical meristem. Based on the genetic program, a leaf is...
