something in the red oak family - could be pin oak. The 'fruits' are most likely 'oak apple' galls

Thanks for all of the suggestions and help identifying these trees. I have only lived here a little over a year and am finding I have .56 acres of "where do I start". Any and all help is greatly appreciated. Per request here are twigs from the first two plants. Ignore the numbers and letters written on the paper. I lost a brain cell somewhere in the process and messed them up. This first photo is from the mature tree: The next two are from a juvenile tree: The smaller twig in this photo is from a juvenile tree. The larger from the mature tree. I think I have two more questions: regarding these cherry/elm trees. The juveniles are popping up on the opposite end of the yard away from the house. Is there any particular reason why I shouldn't let them just grow? WIth the exception of a large flower bed in the middle of the yard and all the trees jammed in at the border of the property my yard is pretty much a large expanse of lawn. It would be nice to have a few more trees! And as far as the poplars go, there is a dirt road that comes up beside one side of my house. I'm thinking these might be a good privacy screen for that side of the yard. How well do they transplant? Thanks so much!

you have a pretty nice scape there... all our comments are simply critique .... worth nothing if you dont want to hear it ... pic 4.. again.. a juniper ... my feeling aside regarding poodling.. it is blocking the windows .. and in my eye.. detracting from the value of the HOUSE!!! ... your investment is the house.. not the plants ... start by looking ONLY at the house.. then start moving your focus back.. thru the plants.. and begin.. by starting to 'see' which plants are a negative to the value OF THE HOUSE .. rather than the plant itself ... i do NOT like the brown on the poodled plants.. and that is once or twice per year trimming job.. on a plant that will bring blood to your hands and arms .... or is a great checkbook garden project ... its not the shape.. from my perspective.. but the cost of maintenance.. either in labor or money .... they are a high maintenance girlfriend .. if thats what you want.. so be it.. lol ... but sooner or later.. the wisdom of the whole situation may begin to escape you ... lol ... again ... the is NOTHING WRONG with your scape.. other some plants are overly mature.. and you should think.. long term.. about how you will be moving those out ... otherwise.. its your scape.. so do whatever makes you happy ken
