I had a request by a tree specialist to scan a tree. I suggested that compressed air be sprayed inside the suspected dead areas after a sunny day. The air may show colder in the scan. Any thoughts, as I don't think this will work. Peter

warm air might be better. It will be difficult to contain given the porosity of the tree area you wish to inject the air. I agree, difficult if not impossible.

I introduced thermal imaging on trees to detect decay and/or cavities in 1984 and I don't need to inject any air nor to do anything on the tree. You can reed my papers that you can find on the Internet or I can send on request. I have been measuring thousands of trees since 1984 and in some cases I have tested the results with invasive instruments or by felling the trees. Giorgio

Giorgio: I would be glad to read your online articles, but you have not given us very good pointers to enable us to find them. I actually did a google search for infrared and Giorgio. I found that there are a lot of Giorgios in the infrared industry. How about a little more information? Such as: your last name, your affiliation, or links. Jack

I have never measured termites (in Italy they are not usual): I've only measured cerambicides (Cerambyx cerdo) on living quercus. I think that as thermography can point out the presence of decay and cavities in living trees, I'm quite sure you can make evident the presence of termites in living trees (that, if I'm not wrong, make devastating attacks destroying the wood). For a skilled user it's possible to point out a single cerambicide hole, so depending on the dimensions of a thermite hole, you could even point out their presence (but this is to be measured - I repeat I have never measured termites). I send you my papers to your email address. Do not hesitate to let me know more about your tests and findings. Best regards Giorgio

Re:Tree Health	Top Gun	11/7/2008
In Michigan, an introduced Asian pest known as the emerald ash borer has been destroying millions of ash trees. Adults of his insect burrow into the bark and into the cambium layer, lay eggs, and dies. The eggs hatch, the larvae burrow all around the nearby live tree cambium and destroy the flow of nutrients from the leaves to the roots, and the tree dies. Our neighbor had three 12” to 15” trees in their yard that started showing signs of the pest: sprouts at odd places on the trunk and thick limbs, away from the crown. I picked out a calm morning, after a cool night in the summer, when the temperature was rebounding relatively quickly, trying to take advantage of any difference in heat capacity of the bark and underlying undamaged or damaged cambium layer. I presumed that there would be a different heat conductivity through the cambium and bark from the wood part of the tree (xylem, or sapwood) based on whether or not the cambium layer was disturbed. I closely inspected these trees with my Agema 570 with its 320 by 240 detector. I could not see any variations whatsoever in temperatures of the surface of the bark, sunlit side or shadow side. So I just concluded that IR was ineffective under these circumstances to detect this kind of pest. It would have been great if IR would see this pest readily, as we could then use it to identify infected trees and remove them immediately, and destroy the pests in progress.

I've already posted a replay that doesn't appear: maybe I made a wrong connection. Anyway, I agree with you that unfortunately thermography is unable to detect these pests because the hole they produce doesn't create any thermal effect. It's only a physical damage that makes the tree to die at it would happen if s.o. makes lots of holes all along the trunk. You can only see the hole on the bark, not the internal burrow. Only if an attack creates a thermal effect (e.g., a fungal infection or a bacteria attack or maybe termites that create a nest-read my answer to kiwi) thermography points out this effect. Giorgio

Giogio, We found some decay and new growth on the branching areas. However, we cannot find decay. Please kindly let us have a copy of your paper as reference. My e-mail is: nigeloko@gmail.com Thanks a lot.
