I am trying to confirm this as a Garry Oak,... Quercus garryana

anyone out there seen enough of these to confirm or deny my tentative ID?
 
thanks orc. I figured I had her nailed. it is planted in a landscape setting (english oak is rounded-ish lobes too) but.. client said his grand kids had brought him acorns about 20 or 25 years back from a local lake, made me think it was garryana, round here there arent near as many as there once was, a few stands on vancouver island but getting scarce on the mainland. I told him to take care of those two trees, he had a couple of natives and they are getting scarcer every year goes by. He was pretty proud of them to be honest, nice to see.
 
They are everywhere here in the valley. I loved them doing line clearance because they grow so slow, only needed to get a few feet of clearance.

Here's a shot of one that lost a limb a couple weeks ago. Summer limb drop 18" limb. Prerigged it to the hobbs and set another rope to a different tree to prevent it from swinging toward the house below. Started cutting on the limb tips until it swung free.

So then he hired you to test soil, fert and mulch, right?

Those thin crowns are hollering for help from below.:(
 
A common problem here with the white oaks in lawns is overwatering from irrigation. They get Armillaria. Noticed a lot of antyhracnose last year which isn't usualy a huge deal, but can be. Lots of carpenter worms in stumps too. And people that don't know about the gall wasps, sometimes freak about them.
 
Guy. no I was actually there to check out a Davidia (single large limb, rapid dieback - found borer holes) and I saw these on the way out and chatted him up about them (the oaks). I suggested that he should watch the water, I saw he had a lawn sprinkler on the one tree that was raining his veggie garden and teh tree at the same time - too much watering for my liking. Friendly old fela, I did the call for next to nothing considering it was a 45 minute drive each way.
 
second pic of the Davidia.. injured branch is front and center, lower part, branch originates from about 4 feet above ground level. took me a couple minutes to find the borer holes, had to bring out my 15X hand lens and check out the small sawdust leavings on the branches..
 
so Orc... lets get some bigger pics eh? even the dialuppers should be able to take a shot at least 2x or 3 x that size.. that limb hanger looks like fun!
 
That hanger about made me crap my pants. It missed the roof/gutter by 2" when it broke loose. A GRCS or two would have been handy on that job, it's heavy wood.

It looks good quartersawn too:D.

Had to check the disease handbook and make sure the Armillaria thing was right. "Surface watering in warm months softens the main roots in the crown area and favors the progress of the fungus."
 
I don't think that's the oak native to Oregon - garryana.

Your photo shows leaves that widen toward the end, and the full view of the tree - the form doesn't look right.

Oregon oak leaves are round lobed, but the leaf is narrow at the petiole, and then the middle lobes area is wider, then it reduces width toward the end.

Like a lobed oval, or lobed orb. It's usually not a very big leaf either.

I think my mom ran off with my ID book - wouldn't you know it - the only day this month I want to look at the page of leaf shapes.

Your leaf looks closer to the shape of alba in Dirr's book - but there must be a dozen oaks that share your leaf shape.

I can't vouch for my screen color settings, but the photo you posted last, seems to show a purple or colored twig. I think garryana is either green or green/gray.
 
Mario, if you get your book back and have any further ideas, let me know... this is basically to satisfy personal curiosity in the long run.
 
the more I stare at it the more I think its english oak after all... oh well, lets see what morning brings for comments? you guys should all be in bed by now anyways I think, including me. and Nathan in Munich... he is just having breakfast if my clock is correct.
 
Orc... dont feel bad, we ask for input, we get input, when the answers elude us we all gain wen clarity is reached... haha but keep the chain sharp, on the ground its called firewood, no matter what it was when it was growing...
