    Woodpecker Damage on Silver Maple...Should We Remove

    Since the power line or previous topping (reduction) seems to be a likely cause of the internal decay and rot, it's almost certain that any amount of reduction will trigger more rot and decline. Given the location around power and building along with the cavity and decay and wounds, that tree...

    Unusual Trees

    Outside of places like Japan, certainly. I don't think I've seen one any bigger around in Oregon. In Japan >>> https://www.nippon.com/en/views/b05310/venerable-blossoms-three-of-japan%E2%80%99s-most-revered-sakura.html There are apparently some ancient ones over there.

    The Tree ID Thread

    Out here, that would resemble Oregon grape, Mahonia aquifolium, or also the Mahonia nervosa which is similar but shorter.

    Is the IP address out of Pakistan ? Looks like SEO strategy from the 2000 to 2005 era. :)

    Unusual Trees

    That tree girl emailed (and or called) a few years ago to inquire if she could see if I could give her a head start to reach some of the larger coast redwoods or new discoveries. She got "cold feet" aboutDecember, and also said she had arborist CEUs to catch up on. She was also worried about...

    Unusual Trees

    There is a 4th burl in the distance almost as big as the other 3 burls. One of the largest is out of sight off to the right. Could only get so many in one photo.

    Unusual Trees

    We passed this group of redwoods in the midst of Jedediah Smith redwood park up a fork of Clarks Creek. There was an unusual assortment and number of large redwood burls, most of them like 100 feet or more up the trunks. Just one more reason I don't equate fire with burls. Much of what we...

    Unusual Trees

    Depends on where they grow. Part of the cause can vanish. A rotted trunk can push a tree over, then itself vanish. Years later, a snow load that may have bent the top the other way is 80 years melted into the past without a trace of evidence. The following is not highly unusual, but is unusual...

    Unusual Trees

    Rather large epiphyte growth. Must be plenty of decay down the center of the Mulberry. If it lasts long enough, the Cherry should split it open someday.

    This old Sitka Spruce near Tillamook Oregon is a nice tree. About 11 feet diameter.

    Unusual Trees

    It's in Portland's old north / northweast neighborhood. If I recall ... somewhere near NE Ainsworth Street x NE 20th within a 15 block radius. When I stopped to look. I was guessing if this kind of tree ever had to be removed, it would be worth air-spading to cut roots and hoist as much as...

    Unusual Trees

    This is a maple street tree up in Portland. I think that's a burl base. I recall this being about 8 feet wide at ground level. Took this photo quite a few years ago, so I don't know if the tree is still alive. Probably is though.

    Champion Trees

    Several of the champion size Port Orford cedars have dead tops. It's not disease related. It gives character, just like how Elk antlers. Dead bone tissue that develops, and falls repeatedly.

    Champion Trees

    It's lasted this long without your pruning. And it will probably outlive your family's next generation or two, if not more.

    Champion Trees

    We found a Port Orford cedar yesterday that's not a champion, but may be the 2nd tallest. I found articles noting one 248 feet and an old 1968 nomination at American Forests much fatter and 242 feet. But conifers.org is usually up to speed, and lists 238 feet as 2nd tallest known. The tallest is...
