There are Tree of Heaven all over this neighborhood. There are at least 3 large fully grown trees near my house alone. There is one giant female tree (taller than the house) in the front/side yard located at 10181 SE Sandview St. Milwaukie, OR 97222. There are at least two other giant trees located in the side yard of 10150 SE Sandview Lane Milwaukie, OR 97222. There is another medium tree located at 10182 SE Sandview Ln Milwaukie, OR 97222. There are also about 5 saplings (about 3 that are 4 feet tall) located at my own house that we have poisoned recently following the instructions from the Penn State Extension. We waited to poison them until the time of season when the video recommended, which is why they are now currently so huge. There are also tons and tons of saplings around this neighborhood in yards, ditches, the sides of streets.
