I'll be attending a hazard tree work shop in a couple of months. I have time to prepare for it. Would any1 recommend some reading material besides the I.S.A. pubs which I already own (- diseases of trees and shrubs). I have my eye on the Tattar book.
Who is giving the workshop? You'll want anything they've written or the book they will rely on.
The Matheny & Clark hazard book from ISA is a must. Body Language of Trees by Claus MAttheck is important. Go to www.tree-consult.org. Go to English Publications and download the papers. Interesting background. Understand you probably won't understand it in the firts 8-10 reads! And that Wessolly and Mattheck disagree about most things.
"Hazard Tree Web PAge" is maintained by USDA Forest Service and there is a National Parks Serve "Hazard Tree Guidelines." Both on-line of course.
The workshop is listed in the tree industry calendar in Arborist News. There also was a flyer sent to members advertising the workshop.
I appreciate the leads you have provided for me. The material in Dr.(?) Brudi's site is intense. This is the stuff I dream of using daily. Right now I need help understanding stiffness scatter. I haven't found anything good which explains it.
The others are more practical in the sense
they give me a good starting point of how to identify and classify tree defects. The Urban Tree Risk Management guide gives the best introduction to risk classification and identification I have read up to this point. I have not read the whole manual. The I.S.A. manual gives more detail about each defect.
I would like an introductory text on pathology. A text which teaches
about the various types of root and wood rots most commonly associated with tree defects. I'm thinking Tattar's book ought to fill the void. Anybody?
I have attended the hazard tree I.D. workshop-good workshop. It was given by Dr. Bruce Fraedrich of Bartlett labs. Essentially, the workshop simply reinforced information from reading material I used to research the topic before attending it. Researching the topic of hazard tree I.D. was the best thing I did in preparing for it since there was a lot of information given in the 1st half of the workshop. I wouldn't have retained all that information.
Scott: thanks for the leads.
The Urban Tree Risk Management Guide published by the USDA Forest Service received a good recommendation by Dr. Fraedrich. It can be found at:

Bit late in the day for a reply but, I've just brought the latest from the Mattheck stable; Manual of Wood Decays, ISBN 0 900978 35 X, published by Arboricultural Ass., website:www.trees.org.uk, A5 size, costs about £20, covers about 29 fungi (photos 1 page, description another) plus approx 50 pages of pre info and 10 appendices. Information & usefulness compared to price I'd say about 8/10
Yes, the Weber & Mattheck Book is a good addition to your bookshelf.
For US readers, the Arboricultural Association is the publisher, and last I checked the only outlet... the are not offering it through other book sellers. Do a web search and you should find their web site. You'll have to add some airmail cost. And the $US is weak against the pound right now.
The general information is broadly applicable. Be aware however that the fungi treated are European and some of the photos and other very specific details may vary from Noryth American fungi and their actiona as wood decayers.
