"D-bag"?

Sorry to cause offense, Lord Muck.

Hey buddy I didn't come here for a soap opera so if you have some knowledge to share on this subject from all your self proclaimed certs and shigo readings then please do so, otherwise it all BS to me.

 

[tree MDS]

Well ya know tree work is much like building the atom bomb , very complex delicate HIGHLY EDUCATED work here so only a few are truly qualified to do it , Its like a calling a "trashman" a waste management professional , you can think of as many cool and trendy names as your mind can create your still just a treeman a step above a lawn man so what...

No way man. Treeman is many steps above lawn jockey, some of us just haven't reached the official Arborist plateau yet. I still retain hope for myself one day though!

Hey buddy, where you have added ANY knowledge on this subject yourself.
"Hinged" or "Shifted" my azz, you little hick.

I cannot hardly contain the pleasure in saying what you 2 guys say about this program/system/accredation amounts to zero point shat. You 2 are the purest form of example of the losers this change in arboricultural history will affect. Couldn't find a better example on AS.

This is happening as we speak, no denying, debating or challenging it. You 2 cannot even take the program as you have to be a CA to take it and you have to have knowledge beyond that to pass it. Good luck in future change in careers. :msp_thumbsup: Wish the best for ya. Painting might be a good option lol.

Well Vet...........I am a CA & have many other certs/Licenses to add to my dosea of tree work!.......first off the cert we are speaking of is absolutely a money making bag of crap! Treeseer would save a corpse, put lipstick on it & say look "mission accomplished" & much like Bush........he along with others are caught with their heads in the crease of a Cert givers azz.

The fact people would even consider this as a certification is laughable!! I could see as a CEU or a domain in future CA testing? But a stand alone Cert..............NO! there is a point of ridiculous & a point where Licensing, skills & continuing education should make up the field & I prefer the latter, I have seen people waste their money on certs only to be layed off while others with nothing remain......Now another cert with promise of big money career choices....LOL

Tree risk Assessor........look at the base word in there will ya!



LXT...............

 

[treeclimber101]

Man.....you'd think I'da pisced in you'se guy's Wheaties or somethin. Didn't mean to set you both off in such a tizzy. I know you guyz can figger what tree should come down.

I am not upset , you know that I got mad crazy stupid love for your ol' wrinkly azz , I am all for the new LTE testing here in joisey and will be studying my fat azz off to make ya proud .... I just hope your here to see the pics of me ....

 

[tree MDS]

Lol. This really is a tough crowd. At least we try and keep it real though!

 

[treemandan]

I wanted to ask you guys who have studied for or taken the exam if any of the material covered trees uprooting on hill/creek sides?

I've already agreed on removing x amount of trees here because they've had two trees uproot and hit buildings. How would a Certified Tree Risk Assessor approach a job like this?

To me it just seems like what goes up must come down, this risk assement course deals very spefically in timing.

 

[Pelorus]

Is the assessor able to predict when a tree is going to fail?
Sounds like a black art. Timing is everything, lol.

How about some common sense here.
Abate the hazard by removing the suspect trees, or stay awake at night worrying everytime you get lots of rain and high winds.
The leaning trees are going to eventually come down either due to root/ground/shear failures.
You remove X, Y, Z trees and decide to leave T, U, & V. What happens to that client/contractor relationship when V uproots and hits a building?

that's what I was thinking, seams pretty obvious from the pics

 

[Shaun Bowler]

I feel that being a Certified Arborist has become equal to a Certified Crossing Guard.
When we took the CA test was'nt all this stuff covered?
I am a CTW as well.
If the ISA, or our industry, wants to raise the bar on "Professionalism" then all tree care "Certified" should be Certified Tree Workers First

 

[treeseer]

This kind of fearmongering statement is very common, but unfortunately lacks sense, because it lacks other abatement options, like pruning, guying, root invigoration, etc. Try this work; you'll like it. :msp_thumbup: The OP trees are newly "edge" trees because the land was cleared before the house was built; now the occupants blame the trees for the problems. They are idiots, but arborists have no such excuses. Tree guys would know better with a little education. 10-20% reduced from those sprawling leaders would reduce risk significantly. Why wasn't pruning in the conversation, Mike?

Also, the statements above about the folks who wrote and administer that course being lazy asses who don't know tree work is also nonsense. I know the guy who wrote the course well, and most of the present instructors (no creases thanks :eek2, and they ALL were doing physical work like takedowns when some of these AS sack-swingers were still in diapers. We may be older now, and making as much per hour consulting as a full crew breaking their backs, and machines, but don't be hating us for that--Join us! I have never seen a market where a well-trained arborist could not make a good living focusing on consulting arboriculture, instead of removalism. an example fyi:

This Quercus phellos measured 113 inches in circumference at breast height and is a significant risk. Visual inspection of the lower trunk on the sidewalk side of the tree revealed a large, relatively fresh, vertical crack.

At the top of this crack is a black growth resembling a fungal fruiting body. Coupled with the hollow soundings produced 360° by our rubber hammer, this indicates the progression of interior decay towards the bark. The crack suggests the tree is not walling off decay well and that there may not be enough of a reliable shell of wood near the crack to support the tree in an extreme weather event. We also noted fungal infections adjacent to pruning wounds in the canopy, which also indicates the spread of decay. The pruning wounds do not appear to be closing.

View attachment 204171

Seven reasons we needed not climb the tree to inspect this area, left to right:
1. Large branch over the road, visibly decayed back to a node near the trunk. This area has a concentration of chemicals and structures that make it a branch/bud protection zone. It is also “hot spot”, in the Zone of Rapid Taper. Considering the Town’s short pruning cycle of 1-2 years, the size of the branch and the extent of decay are significant.
2. Apparent saprophytic fungus (which grows on tissue that is already dead), perhaps Stereum sp., is spreading towards a similar “hot spot” node on a branch facing west.
3. Recent pruning wound being attacked by this fungus.
4. Nearby pruning wound not closing.
5. The most recent pruning wound is also not closing.
6. Apparent parasitic fungus (which grows in living wood), resembling Polyporus, grows on included bark between this wound and the largest branch/leader in this midstem area
7. Upward-pointing structure above the fungus advancing up this leader might be loose bark affected by decay.

If only one or two of these signs of disease or symptoms of tree response to disease were evident, closer inspection and precise identification of pathogens may be warranted. In total, they point to interior decay and poor condition, beyond any mitigation. Removal should be strongly considered. The sooner the tree is removed, the quicker a replacement tree can be installed and begin establishing its roots.

MANAGEMENT OPTIONS
The other trees with visible fungal fruiting bodies or audible hollows noted should be assessed with a noninvasive decay-detection instrument such as a tomograph. The extent of decay will indicate potential mitigation, such as how much and where they should be pruned, for health and safety. Vines and other growth should be kept clear of the stems of all the trees to permit inspection. Mulch should be spread near—not on—the trunks, to prevent further damage by and to lawnmowers.

The primary problem these trees have is root damage during work on curbs and sidewalks. The upcoming final report will include appendices describing ways of maintaining safe walking surfaces and adequate water direction while minimizing impacts to the trees. For now we recommend the City of cease any further pavement works adjacent to significant trees until City staff, including Streets and Grounds, is familiar with all reasonable options for these works, and with relevant industry standards and references.

This concludes our preliminary report. We can clarify any portions of it upon request.

Sincerely Yours,

Actually, this particular owner is very reluctant to remove trees. Pruning will be discussed after removals. I recommended 11 removals which 4 were already done before I took the pics. That leaves seven more to do. Yes, I based this decision on experience and common sense. I'm always anxious for more knowledge though.

 

[Mike Cantolina]

I'm mistaken, 5 were already done leaving 6 more to do.

 

[treeseer]

Actually, this particular owner is very reluctant to remove trees. Pruning will be discussed after removals.

Why wait? Owners needed to know about pruning options before getting removal quote. The ones left look like 1 day's worth of pruning, 2 men, pack the brush on the slope to slow erosion and improve root stability. No chipper required.

The removal approach increases erosion and lessens stability of the remaining trees. If there's no climber or aerial lift access or the pole tools to make those cuts, find a sub, or buy 'em.

Del, directional pruning has been done for decades; the trees can grow larger AND more stable; 3-5 year cycle, forever. Owner keeps a growing asset, you have steady work. Of course if felling every 30-40 years is what you and the owner want, fine. You don't need to be as logical a scientist as John Galt to figure that one out. Eddie Withers would know it right away.

Objective: • Leaning trees on hillside

Enhance structural stability and symmetry; minimize lean, decay, weak attachments, and heavy ends.

Specifications: General: All pruning shall be completed in compliance with A300 and Z133.1 Standards.
Detail: Remove all dead branches >1”.
Reduce all overextended branches back to a favorable lateral, or to the origin. Reduce rubbing or decayed or cracked branches to restore symmetry and maximize collection of sunlight.

No more than 20% removed from each tree with 1-3” cuts


Cmon guys this is basic stuff.

 

[mattfr12]

I really like that idea tresser and have tried to sell it myself a few times i just wish the general public had an appreciation for trees like i do or most other people on this site they usualy want them just cut down and its hard to talk them out of it. sometimes if you keep pressing them they just give the job to someone else.

example i got a call to remove a 70 foot red oak i mean this tree was beautiful no rot to be seen perfectly straight. but they wanted it out. i tried selling reduction like that tried pushing cableing on them. explained to them what it takes to get a tree like that. but in the end they said they dont wanna rake the leaves or what them on thier new roof. so we ended up doing it i mean this tree was so healthy and stout well over 60" at the base. i finally got to use my 3/4 inch rope and the hobbs device it would take one hell of a shock load.

i agree with you on the idea ive been in buisness long enough where im finally getting paid again to work on the same trees some on thier 2nd and 3rd time.

 

[NCTREE]

If what the majority of you are saying that "what goes up must come down" and "the tree will eventually come down so why not take it down now" then anyone could be an arborist including johnyonenut working at the turd factory. It takes alot of expertise to come to that conclusion.

I get reall bored with the same old #### of the everyday removal grind, it's like working in a factory same #### different day. I need to learn new things in order to keep myself from going insane. This a subject I find interesting and want to learn more about. I'm sick of hearing the broken record some of you guys spew out your trap door just because your stuck where your at and refuse to better yourself doesn't mean everyone else feels the same way. Go take your negative crap somewhere else you miserable SOB.

Oh yeah and polerus I'll take "hick" as a compliment coming from your mouth Mr Ontario! Blah Ha Ha Ha!

"This kind of fearmongering statement is very common, but unfortunately lacks sense, because it lacks other abatement options, like pruning, guying, root invigoration, etc."

The rationale used by some municipalities to NOT brace and cable trees is that doing same acknowledges the tree poses a hazard in the first place, or such work would not be unnecessary. The cabled tree subsequently fails, and then what? Are you telling me that getting caught up in a litigation battle is worth this hassle?

More common sense is involved here than fearmongering.

I'd like to hear more about root invigoration. Seems that invigorating a leaning edge tree on the side of a creek might not be such a great idea, imo. How much is guying/pruning gonna cost as opposed to removals? There is not just one magnificent heritage specimen tree that is being discussed in this particular situation.

If these abatement options are done, I have to imagine an explicit disclaimer will be attached to the contract not holding the arborist responsible if and when the tree fails at some point in the future.

" How much is guying/pruning gonna cost as opposed to removals?"

One day 2 men, as noted. no guying on this needed imo, tho it would buy extra insurance for the really scared client.

"There is not just one magnificent heritage specimen tree that is being discussed in this particular situation."

No,, but there are many in the making, if arborists train them.

"If these abatement options are done, I have to imagine an explicit disclaimer will be attached to the contract not holding the arborist responsible if and when the tree fails at some point in the future"

A variation of this goes on most contracts. note #10:

[treemandan]

When all is said and done there is a whole lot more said than done.


I am sure there is something to be gotten from this assement course. It may be like that project mananger course I took where I thought we were back in first grade with the elementary stuff they were talking about. To be certified?

In a situation like Mike C posted its easy to get what Mr. Corbin what saying. Sure, options are present in most situations, they should be discussed.

Fear mongering is something so easy to do one may not realize he just did it. Sometime its little far fetched: one time I said " Well this one missed ya, it kinda looks like the next one will kill you in yer sleep." It was a possibility.

And sometime I look at a thing and immediatly the only way I want to handle it is to chop it the #### down just to get to end whatever debates that would confuse the situation.
