I’ve noticed that many practitioners in Sweden often overlook the significance of ”ribs” (ås or barkås in Swedish) on tree stems and branches.

I’ve been using my Arbotom tree tomograph instrument for a year now and am very impressed with its accuracy.

Unfortunately, Aspen are host to a number of pathogens, some of which can have a significant affect on the tree’s structure and safety. Due to the large number of Aspen in school playgrounds, I’ve recently been paying more attention to these pathogens. Fortsätt läsa ”Cankers on Aspen”
Inonotus obliquus, also known as ”sprängticka” here in Sweden, is an interesting fungus. I’ve only seen it in Sweden and only on Birch (Betula spp.). Recently I’ve been comparing the actual decay caused by the fungus with the readings from my Rinntech Arbotom tomograph.
