I know practically nothing about different trees. I have always bought mixed hardwood cords or cut trees that fell in the yard. For the first time, I am heading out into the woods to cut firewood. The sum of my knowledge is: seek out hardwoods avoid pine. Other than that I don't know that I could tell a maple from an oak from an ash. Does it matter? Short of learning to ID all the various trees that might be in my area, is there anything I can do to make sure I bring out decent wood. For what its worth, I'm going into Ft. Washington State park. For a $15 permit they'll let you haul out as much wood as you want, you just can't take down standing trees.
