Location

Trees of heaven. Growing and spreading VERY quickly, sending up shoots thoughout the neighborhood, over 100 feet away from actual trees themselves. Killing other plants trying to grow under them. Starts grow about 1 ft a week. Location is about 100 yds from Clackamas River at High Rocks.
Lot owned by absentee owner, corner of Princeton and Arlington, Gladstone adjacent to Safeway / High Rocks Pub. I own 2 properties directly uphill from there, 825 and 805 Berkeley St.
