    Syrup from the Twin Cities

    The white stuff on a cut petiole of Norway maple is latex that is produced and carried by the symplast of the phloem. Not at all part of the xylem sap stream of the apoplast, which is what is collected for sap/syrup. of the stream of xylem sap. One can tap any dang tree. Diffuse-porous...

    I like big butt(ress) and I cannot lie

    Thanks for the euc survivor. They are tough! The creature responsible for the hollow appears at about 32-35 sec in to the clip, perhaps. Looks to be long-past fruiting, but the western sulfur shelf polypore may be a foot or two above the obvious cavity. Nice!

    Palm ‘lumber? Questions

    The Wood Databse gives the specifics on wood quality for several palm species. Timber trade names and arborist/gardener names don't always sync. The Red Palm of timber I think of as coconut palm. https://www.wood-database.com/red-palm/

    The downed logs show good examples of the pouch fungus, Cryptoporus volvatus. No, I realize no one asked for the info but this is an interesting one with a few more details here and here. The fir engraver beetle carries the fungus from tree to tree. A good symbiosis...from the point of view of...

    Strange Bark on Hemlock

    The pattern of cracks and small holes is more consistent with Felt Disease than Crown Gall which usually retains bark patterns with inflation! Easier to exclude Felt Disease than Crown Gall, the latter of which is usually hard to tell definitively from a single specimen. Still, could be!

    Strange Bark on Hemlock

    Difficult to confirm remotely, but I'd first rule out "Felt Disease" produced by Septobasidum species. The fungus felt covers scale insects and forms a mutually beneficial relationship to the fungus. Does it matter to the tree? Lots on line, I'd start with...

    Sorry for late reply! Of course there are a bunch of white rotters that can occur on living red maple. But the image definitely looks like the white stringy rot produced by what I learned as Polyporus glomeratus and which has been variously placed in various segregate genera including Inonotus...

    Fire damaged trees-advice

    I have no experience with fires from burning buildings, but in wildland fire we get a sense of intensity from the presence/absence of scorched bark and if present, how high it extends up the trunk. As for survivablity under a given exposure to fire, species makes a big difference. But of...

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

    Thanks all and especially Roger M for your participation here. The session was way fun for me! None of my stuff would have been new to you folks, to be sure, but there is a place for missionary work.

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

    Beautiful! Just out of curiosity, what happened next? I see the log with the cavity openings covered in mesh. Did you move the log to a "safe" place and let the little rascals free or ?

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

    Thanks OOM, yes, honey bee colonies can pose a serious threat! The Honey Bee Watch program is a citizen observer advocacy group for free-living honeybees (which are not native to North American). The challenge is that feral or free-loving honey bees have been shown in some studies to drive out...

    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...

    Oak wilt risks & precautions - NE Ohio

    Evo, susceptibility does vary and/or the time before symptom expression. Red oak are most susceptible as a group, white oak is less susceptible as a group, and bur oak are intermediate. A good treatment out of the midwest is linked here...

    Hey Look at My Crud...

    I'm running a bit behind here, but as to that strangeness of brambles from SL in March: I'd start with cane gall or hairy root caused by one or another Agrobacterium. Same genus as crown gall, but their own species. So what you see is the result of the hijacking of localized bramble tissue by...

    Reductions.. is 10% too much?

    Yes, that was Ed Gilman's work, a prominent name in pruning research.

    Odd ‘clam shell’ growths

    Thanks for the longitudinal view along the radius. That tells me "yep, the unusual growth is wood tissue." Without any other info, I'd go with "crown gall" caused by Agrobacterium tumefaciens. Lots online on that one....but may not be too much help as to "why".

    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!

    Beech bark disease?

    To answer Treeaddict, yes, Nectria (in a broad sense) attack of beech is not limited to Beech Bark Disease (BBD). TheGreenOne is on the right track. BBD usually presents as a legion of small cankers (quarter- to half-dollar in size) with the floccose scale insect being much more obvious than...

    Japanese cherry trees planted in Washington, DC

    I was down at the Tidal Basin at peak March 18th, just a few weeks ago. Quite splendid and 1-2 weeks early compared to historical norms. A landscape metaphor for transience.

    Weird stone like fungus

    This is where 2 minutes with a razor blade and a magnifying glass would save a lot of guessing. I think I see a pore surface and the hard consistency points towards Phellinus, and the dimensions suggest P. robustus. Could be! Again, not much to go on.
