How many tree species do you have in your yard?

[Arkansas Granny]

13. In my yard and the empty lot that ajoins it there are pecan, maple, elm,

mulberry, mimosa and native willow trees that grow like weeds. There are also a couple of oak seedlings that have sprouted in my flower beds that kept their leaves all winter and are now putting on new growth. I would like to transplant them, but I've heard that they have such a long tap root that it's very hard to do this. At any rate, they are not in good places and will have to go away, one way or another.
