Looks good. Thanks for posting a shot of the bark of that maple; been interested in how they look. At Nashville Zoo in Tennessee, I like looking at the lacebark elm trees on grounds.

Richard.

Nice -- thanks. Heavy crop of ginkgo fruit. If they'd have planted thorned honeylocust they may not have had to protect them...

" If they'd have planted thorned honeylocust they may not have had to protect them..."

I'm not so sure; I think most of the large African herbivores eat very thorny Acacias with impunity.

What can I say about the (east coast) MP: they always look so good before they die LOL. My memories are growing vague but IIRC the one I saw in Columbia, MD, looked like this in fall 2005...it had a few sickly branches the next summer or maybe 2007, and was gone when I last drove through the neighborhood in 2008 or 2009. It was about the same size. The Zoo surely has a professional horticulturalist on staff and is he/she perhaps treating in with a fungicide /"oomyceticide"? Many root rot pathogens are not true fungi.

The Sectiion Trifoliata maple is Acer triflorum, if that is not clear to anyone looking at this.

Yes - water molds are not fungi, are instead related to brown algae.

The second largest MP on the east coast, in Bethesda, MD, had more of these dying _lower_ branches the last time I saw it, maybe a year ago, but it still seemed to be healthy, overall. I'd be more concerned about dying branches near the top of the canopy. I wouldn't say it's growing quickly, but it's noticeably bigger every time I see it. (which is only once every 5 to 10 years!)

I wonder how the one outside Dumbarton Oaks is doing but I never have time to get over to that part of the Imperial City.
