Here are a few examples of wording in my contracts:
Large Red Maple on the front right corner of the house (Prune out major dead wood 2" and larger, Prune back one side of co-dominate trunk back to a lateral branch, thin canopy and remove the debris).
Medium size White Oak on the front left...
Very interesting find Oldoakman!
I recently took down an Oak that I believe to be a cross between a White Oak and a Chestnut Oak. The bark was closer to White Oak, while the leaves were more Chestnut looking.
