I am trying to diagnose what I believe to be a fungal infection on a group of Q.suber (cork oak). The black staining is all the way up and down the trunk/stems, and seems to correlate with the sides that get the least airflow. Trees with buildings immediately west of them have the symptoms on...
I have spent a few hours now trying to find an aerial rescue training offered anywhere west of the Rockies, and I have turned up nothing. I found a place called Academy Trained that seems to offer something, but I haven't heard back from them after days, and their answering machine is full.
The knives had been changed about a week earlier. I think they may have forced a t-post through within a pile of brush and branches, feeding it with a Bobcat T86. I had gone home early that day, and the rest of the crew all got fired the next day. I have never seen that kind of carnage. The...
The groundie let a big chunk of oak swing into the winch. My boss would be elated if anyone just happens to have a spare for that plastic assembly that tails the rope out.
I just got my reply from ISA, and I am good to go to take the test! I remember several people offering to let me borrow books, and I am finally ready to actually study up and do this thing, so anyone with the literature that I should study up on before testing that is willing to let me borrow...
So, the more I think about it, the more I see how I could have prevented this. I was 40' up and 30' out on a very sideways branch in a big Raywood ash, and I was on a base tied SRS with my rope over a decent central-ish union up high- about 60'. I had finished one zone and moved to this next...
I just wanna put it out there that if you bought a throttle and used it and wish you could get some money back out of it, I will help you out with $200 + cover shipping. I don't need one, but I am curious to try it out.
Looks like someone has been watching the GRCS mod thread and decided to go all in on an improved design...

I am pretty good at my local tree ID, but I have this odd oak in my neighbors horse pasture, and one more down the hill by the irrigation ditch. I have a black oak down the road a few hundred feet, and she drops her leaves. This one seems to be an evergreen, but I feel like I once saw it with no...
I know most of you guys don't actually deal with these a lot, if ever, but a broader discussion of theory is welcome. I will be climbing this one and just taking of a couple of the lowest branches, broken ones and dead mostly, and then figuring out what to do about the top(s)
It's almost...
I got a gig with an ISP, installing dishes in trees, and was not surprised to learn that until fairly recently, they required their tree climbers to always be on spurs. They understand that there are spurless methods and no longer require it, but many of the guys still do it.
Does the ANSI...
One of my oldest friends in the world, who also taught me loads about soil, is looking to switch tracks in his career and move out from horticulture into tree work. He has a degree from Humboldt State, now Cal-Poly Humboldt, with a specialization in soil science, and he has been managing trees...
So, I have a kink...
In my neck. I have always used a fairly slim pillow, but around the same time my neck stopped hurting from looking up all the time doing tree work, I started just having a different kind of pain. I tried thicker and thinner pillows, both fluffy style, and memory foam...

Wesspur sells these steel thimbles, which appear to be galvanized, and offer them as an option for spliced eyes on Amsteel for winch lines. My local cable shop has the same ones, for the same price, and I went and checked them out, but I...
