Say, hypothetically, I wanted to, for the sake of argument, spread seeds as I went around my usual hiking spots just to see what could grow. Furthermore, let us say, again hypothetically, I lived in the southeast in the lower Appalachians and wanted to scatter seeds that would help the environment in some way be it nitrogen fixing, erosion prevention, or some mix of all of these.

What, in theory, plant species should I go for? Native species goes without saying
