Does anyone have any experience with the SHIGOMETER? With respect to CER.
If so, what are your thoughts on the CER mean for Mountain Laurel? Did you
notice something different about mountain laurel?
I have used SHIGOMETRY to detect woody root declines in trees.
I would really like to discuss Mountain Laurel CER
SDTDC did not test the Shigometer, but extensive research has been
conducted concerning its uses and limitations. It is agreed that the
Shigometer is a valuable tool for determining the current vigor of trees and
forests (cambium testing), but since resistance changes begin prior to
damage caused by decay (xylem testing), the Shigometer technique for decay
detection requires careful application and interpretation. Basic biological
knowledge of the material being evaluated is essential. Skill in instrument
use increases with greater awareness of local biological principles and
practice with the instrument. --
Since you have never studied biology, this pretty much leaves you out.
By the way, do you own a Shigometer?
Don, vigor is genetic feature. What you mean to say is vitality. Or maybe
you don't. It determines a trees vitality and not vigor (CER) which means
cambium electrical resistance within a species.
You must understand the species of tree to use the wire probe. E.g., is it
a heartwood tree or a sapwood tree. What is the difference in resistance
between heartwood and discolored or color-altered wood from a wound or an
injury. Sapwood to heartwood or sapwood to discolored wood. For example,
Don, maple trees do not form heartwood. What about false heartwood? Oaks
do. I tried drilling for the wire probe and broke the small bits. $100.00
per bit. What is nice about the CER is you can detect some woody root
problems. The trunk flare will have less resistance than the measurement at
breast height. However you must understand that trees have trunk flares and
not root flares. Of course you know all of this.
What am I telling you this for? I guess I like you Don. Sorry for all the
bad things I said about you. You are really a nice guy. Don't know much
about trees and their associates relating to the ecological stages of trees,
but you are still a nice guy. I like you.
Show your ignorance once again. Your the one that does not get it.
What kind of question is that? What do you think. Oh thats right, you
I think you are a phony, a fake, a charleton, a con man. I think you were a
saw hand for Shigo, a gofer, and try to parlay his work into your pocket.
You have no credentials, and lie about it. More over, you have no company,
no business address, no yellow page ad, nothing to indicate you are anything
but a yard man. Oh, other than that hand painted sign on your pickup.
If anyone would like to learn how to use the SHIGOMETER contact me. The
reason most people put down the machine is because all the machine gives you
is numbers. You must understand the tree w/anatomy to understand what the
numbers mean. I would be happy to help.
It's really not that hard. You just have to understand anatomy, protection
wood, must know where the cambial zone is. many people think the cambial
zone produces wood. It don't! I will help. Come see me and touch trees
together. On the inside.
Again advanced tree biology is things like mountain laurel CER.
Other than that I am working on a picture story of problems like trees
planted to deep and mulch on the trunk. Just took a closer look today and I
am writing a picture website of what I found.
Coming soon. You will never let this treatment of deep planting and
improper mulching go on when you see this. I did what no one else wants to
do. I'm not afraid.
