I admit to being offended.
While I appreciate your input, I disagree with your advice.
The larvae are so far in the branches. No exit holes elsewhere. I would expect to see the top die back first. At which point I would remove it (the top). The tree may still survive.
I think the...
Needles look good except on at least two branches. In the right light, you can see that they are "off". I will go up and remove them and any others that develop, late winter. I removed all the dead branches. It's a yard tree, near a retaining wall/sidewalk/road on one side. The rest is 2/3...
It is sapsuckers. Willamson's sapsuckers like doug fir. I recently spotted another just like it (without the beetles) at another job (in another town.)
They definitely want to keep the tree, if it can be saved from the beetles.
It must be going on for a long time for the wood to react that way (swell).
What came first, the sap sucker or the beetle. They both attack weakened trees. I guess sap sucker from the drought. I don't see any other physical damage to the tree. No new landscaping either.
Removed about 15 dead/dying limbs with beetle sign.
Exit holes are oval 4-7mm wide. Galleries are up to 1 cm wide, mostly in sap wood. Frass is fine, white to tan colored.
Flat headed fir borer?
Tree is 70 ft with dbh 32".
Took pictures of some girdling rings on the middle portion of the...
It is super light. Cuts great. I have a panther bar on it. The battery doesn't last long though. Also, I bought three batteries and only one would charge.
California has a recreational use law that makes land owners free from liability if they give you permission to recreate on their land. There's a form on the internet somewhere you can print out and have both parties sign, but I think verbal permission is enough legally.
No, it's happens on isolation. I know there are work arounds (ie: more weights, clearer shot, carabiner letting down another line), but the fact remains that a new line comes down easier than a worn line, so I end up buying a new line.
