Roger,
That dead Madrone looks like a tuffy. Get the full price. Who else could tackle that job around you?

Rodger , what do you think killed that tree?.. I have seen may die from to much winter water and blite as well ...

They are dieing from Madrone Canker. Starts with tip die back and the cankers move down the stems to the main scaffolding branches. The leaves and stems appear as if burned. They are even blackened as if from fire.
The Ag. dept states: "Remove infected parts and improve growing conditions".
Not really helpfull advice as often removing infected parts means removing the entire tree or at least so much as to distroy the shape of the tree.
The only visible external signs of the fungus are tiny, black spore-producing structures (pycnidia), which upon maturity erupt through the dead bark. Individual fruiting structures are barely visible to the unaided eye (microscope needed) In mass they appear as a black, roughened surface on the affected wood compared with the smooth, exfoliating bark of healthy branches.
In CA., Madrone Canker is a very common disease on ornamentally planted Redwoods throughout the state. It is usually called botryosphaeria canker and is charactorized by golden-colored resin droplets at the base of cankers on branches, and main stems.
Like Greg Liu said, the spread of this canker is most often associated with wet weather conditions where the spores MAY BE dispersed by water drops, or even carried away by insects feeding, wind whipping, sun scald, freeze damage.
Not alot is really known about disease spread and pathogenicity.
Control is best done through removing infected wood, disinfect pruning tools and avoid pruning during wet weather. Do not broadcast chips as a mulch for save trees as the spores can survive in the wood.
Do not irrigate trees as in a lawn situation.
No chemicals are registered for control.
Hope this helps

Thanks, Mark. I really need to start marketing my work...I have done a little (Oct 2004 TCI- 5 photos) but need to get a 35mm digicam, to go with my $10k worth of pro Canon glass, but the the two Canons to choose from are $3000 and $4500.
I also need to start shooting ski action again, I really miss it.
On a very sad note, a friend, top photographer/ski mountaineer Carl Skoog, died Oct 12 in Argentina. He fell on a 42 degree slope, (not that extreme) and was unable to stop. His partner (also a good friend, who I have photographed as well, found him 4500 vertical feet below.
In 1997, Carl and I spent 10 days in Valdez, Alaska, back country touring and helicopter skiing, site of some the world's best skiing. We had 7 friends/models along, and unselfishly shared the photo op's. The weather was inclement, which limited heli time, but our last day dawned clear with 4 feet of fresh. Carl caught some heli rides with three of our group. The others were sick or had gone home. So I hooked up with the US Extreme champ and his fiance, plus the French champ, and Scott Kennett for two of the best runs of my life. 5000 foot faces, 30-55 degrees, deep stable powder, and 4 awesome models....Kennett had logged oodles of time as a model, both still and movie, many with his famous dog Zudnik in tow....I'd skied with and shot him before, he's a great guy.

Franz...here's a close up of the tree....very little canker in it except for this area. Next pic will be of one with lots of canker but still alive....
[/ QUOTE ]
ahhhhh, now we are talking 'bout arbutus canker, or to be technical Hendersonula toruloidea. Slow growing very gnarled canker that is easily distinguished from the relatively smooth surfaced madrone canker. Keep in mind for identification purposes, branch blackening does not occur with arbutus canker. This canker is usually not lethal, but does cause infected branches to become unsightly.
Here in my area, Madrones have been striken with these problems so I have done some reasearch on it. Hope the info. helps.
Really, really nice pictures Roger

Ah, so there's two different cankers? Interesting.. I don't keep up on the issue as much as I'd like to. Thanks.

Update on the dead tree. The customer called back to Puget Power, and they told him to call Asplundh. Makes sense as the job is easier if done with a bucket by a line clearance certified co....Their price is about half at $1600.
Understandeable, but that would have been a fun (?) and challenging job.
More sour was seeing them in a backyard just up the street from my home...I went and talked to the homeowner, they removed 3 pine, and an elm for $1700..took 2 days for 2 men one day and 3 the other. and still have a bit to go. The climber looked to be quite competent...but that was way underbid...i think we could have done it in a tad over a day...They also cut a dead stub on a catalpa, into the callous and made a horrible rip....bad cutter bad cutter...Homeowwner wished they'd called me, but don't drive my street and didnt know I live there..and missed calling me for a bid as well, other bids were 1900 and 2500. But I have a 2700 prune and removal job two houses away.

Watch out for those wires ! Otherwise goodluck - let us know if you got the job.
Arbutus tree are getting hit pretty hard here. There are about four leaf spot cankers , blister blight, and also a stem canker (Nattrassia )that are causing significant damage. There is also a root disease (phytophthora cactorum ) that causes butt cankers and death of arbutus. Not to forget to mention a leafminer or two and a arbutus skeletonizer ! /forum/images/graemlins/shocked.gif
Sometimes an early winter can kill off new growth before they have hardened off too.

Hey Frans,
From what i understand, Hendersonula toruloidea is an "old name". It is now called Nattrassia mangiferae. Check it out and tell me if i am wrong ! Am also only aware of one stem canker ie the above. The first symptoms are dark discolorations on the bark. The perennial canker will later be formed here. Older cankers will have swollen irregular masses of callus tissue surrounding it.

The residence with an acre which we just purchased in Ruch, Oregon has several Madrone with trunks of about 3' to 4' diameter about a foot off the ground.
This is Madrone country down here.
