Not sure why it doesn't play for you. It has always started to play for me as soon as the page opened up.

Has anyone seen this? http://www.patsummerall.com/videos.asp?nar=1&vid=nationalarborist Thanks, TMW

Thanks to the (small number of) folks who attended this session. We met at the Sugar Shack at 9AM on Saturday, discussed trees, education and philosophy until lunch time. After lunch we went out to the lake house for a walk in the woods with Dr. Shigo. Well worth the admission price of...

DBH Diameter at Breast Height which is taken at 4.5 feet = 1.3716 meter

We finally have a date set for the next free session for students and teachers with Dr. Shigo. It will be Saturday, June 21, 2003. It will be held at the Sugar Shack in Barrington, NH (http://www.maplesugarshack.net/) We begin the day at 9AM at the Sugar Shack with some lecture and...

I think that JPS was referring to not tying in to a single side D ring, as the saddles were not meant to take a shock load on that point (neither is your body). Nick, the standard says: "9.4.4 When large cuts are being made in single spar trees, both ends of the work-positioning lanyard...

ANSI Z133.1 -2000 3.5 arborist climbing line. Arborist climbing lines shall have a minimum diameter of 1/2-inch (12.5 mm) and be constructed of a synthetic fiber, with a minimum nominal breaking strength of 5,400 pounds (24 kn) when new. Maximum working elongation shall not exceed 7...

We are still trying to get a handle on the actual numbers of fatalities in the arboriculture profession. It is difficult to get accurate, reliable numbers. I have summarized all of the fatalities that OSHA has recorded from 1984-2002, but this number does not represent all fatalities, not...

Something else to cut with in the tree, besides a chain saw, hand saw and hand pruner, can be cheap insurance. I carry a Gerber tool on my saddle; very similar to the Leatherman, but I like the nylon case over the leather for my saddle. As JPS said, I have used it mainly for tightening the...

I use a false crotch consistently and occasionally two in the same tree like I did yesterday. I sometimes won't use a false crotch when I am using my pruning lanyard (double-ended with hip Prusik) in crabapples. Otherwise if I am working a tree, I am using a false crotch, even on removals. TMW

I took a quick look at the links to your sites. They look good; professional, and informative. I also looked with a critical eye for safety concerns. I didn't spend too much time looking that closely at the pictures (I'd need better resolution and more time) but things looked good. No glaring...

I concur with John. This is an incredibly sensitive topic. Please treat others like you would like to be treated. Perhaps an example can help to make my point. Once, at a conference, a fatal accident was being discussed. Someone in the audience stood up and said that the victim had done...

Even if there is ice in the spaces in the soil, the soil never really freezes. We just dug through the snow, broke through the ice and pulled actively growing roots and mychorhizae out of the swamp behind Dr. Shigo's house.

FYI ANSI Z133.1 -2000 8.7.7 Splicing shall be done in accordance with manufacturers' specifications.

FYI ANSI Z133.1 -2000 7.2.8 Arborists shall use a second point of attachment (work positioning lanyard or double crotched rope) when operating a chain saw in a tree, unless the employer demonstrates that a greater hazard is posed by using a second point of attachment while operating...

I post on several discussion groups now, not as many as I used to, but I still do post. I post less now, in part because of my positions within the profession. I am sensitive to the potential for my views being perceived as being that of the one of the associations that I belong to/work for...

ANSI's response to charging for standards questions: http://www.ansi.org/public/why_charge.html

Frequently...except I don't have those kind of clients in my regular job. I do have them in 2 of my hobby jobs. TMW

The State is still stalling, but I am trying to set up a meeting with the Governor and the Executive Committee to resolve the issue. This is an election year in NH, and I am also awaiting the results to see who the players will be. TMW

Pretty much. Are you volunteering to help out?
