Yes Dave knowledge is power, and good for you to take the initiative to keep on learning.
With Vwilt you may find green discoloration in some maples and DED is a brown discoloration. It is entertaining playing the detective.

They all necessitate a lab visit for positive ID. Lots don't exhibit fruiting bods, but when they do it is just another indicator and can be cause for alarm when we are dealing with decay causing fungi in the vicinity of a high level target.

Good on you as well, TD, you are also a "fun...guy" (joke intended)

LOL Guy, I will get right on that pissing back thing. With all due respect to the ASCA members, I heard a phrase which applies to MOST of their membership.....SNOB CLUB!

I checked last night and there are 4 ASCA members in the Province of Alberta, none in Saskatchewan or Manitoba. I don't, and have never met the one but out of the other three, two have NEVER climbed or physically worked on a tree taller than themselves.

Guy, your association with ASCA explains a lot about some of your posts in the past! I won't hold it against you for belonging to the "Snob Club". I actually value most of the information that the long term members post here. We should always listen to it all, sort out what will apply to our own geographic, climactic, and area of involvement. Knowledge is pretty light to carry around. And really makes you look good if you can use it to help someone out.

Ah treevet come-on, after you give 'em a slap you gotta give 'em a tickle!

I don't know about you guys but I am a lousy typer, and a pokey reader. But what I read and type, I NEVER forget. Hats off to all the people who go to great lengths to take the time and thought to make their thoughts come to life on a thread page. Of course the ARE a few exceptions! But NO names!

So I am making a list of trees that need inspection by a arborist that specialize in fungal decays. Hey vet didn't you tell me that you could fly just about anywhere for next to nothing? I'll pick you up at the airport on Wednesday morning, and bring your electric underwear!

Classic

PS. Glad to drop into your airport (do I need a helicopter lol) but would be counting on you making up for the weather slowing us down a tad......how abouts $300.00 per hour would be fair?

Well Dave that a fair bit of change, BUT it might be worth it for a couple hours, JUST TO SEE YOU FREEZE UP!

The weather is probably one of the reasons that fungi don't do well here. Dry cold winters, and dry cool summers, with the odd period of wet and hot. It is when it is wet and hot that we see trees that were not noticed to have decay. As you guys know, when they are laying on a house, its a bit LATE!

In 2002 we had the driest spring and summer on record. A friend of mine was the coordinator for the Provincial Cost Share Elm Pruning program. That was the one year that the # of DED infected trees dropped. He thought it was due to the elm pruning program working. I commented to him that fungi DON'T do well in the desert!

BTW, Every time Dr.s Kim Coder and Ed Gilman come to speak to an ISA function in the Prairie Chapter, it is ALWAYS -30C with wind chill on top of that.

I mentioned this phenomenon to Dr. Coder, and he Immediately told the conference chair that he WASN'T coming back UNLESS there were leaves on the trees. Coder got his way and I got in trouble!

It is good that other conditions are not in favor of these pathogens because the tree's defense it is at a disadvantage during the dormant season in the battle with fungi if wounding did occur at that time and you've got quite a long dormant season.

off topic...but the weather's changing big time in a matter of hours. It's been warm and relatively dry here in the PNW for 6 weeks...no snow in the mountains; us skiers are mighty restless.

Big cold front sweeping down the coast, it may snow 5" in town starting tonite....and be in the 20's for highs by Thursday....brrr.....so the snow if it comes will stick around.

Up to 3 feet forecast in the hills!! means I may get to test out the bum knee....

Maybe a pre-test first? It'd be sad to hurt it worse and be out for the season...

Happy shooshin!

Grevillea on it's last legs with ganoderma getting hold, note the pale appearance on the standing dissected trunk is decay rising to sound wood which appears red.
