Yes, it is Pistacia lentiscus. Thank you !

Thanks so much for all the info and opinions. GingerBlue, would geum be growing wild in my woods? although I did plant a Mrs. Bradshaw last summer that died out on me rather quickly, but it is possible that it seeded first, but that was 12 feet or more from this one. And was downhill, seems unlikely? Is there a native variety I am not aware of? So at this point we would say #3 is a candidate for Round up? #1 I don't think is Indian Mock Strawberry since I see no evidence of that type of growth habit on any of them, and wouldn't they have flowers on them by now? So maybe it is a geum? Any other opinions on #1? The alder shrub (I think that is what it is, thanks esh) I assume should stay right? As long as it is not an aggressive I will keep it as it is behind my planting beds in a section where the runoff has channeled a ditch.

Looks like a citrus fruit tree to me. Lemon or lime. Along those lines. Looks like it has been there for a long time if it is that tall. Probably planted before everything else grew up. Needs sunshine to be sure what it is. Leubafr
