Plant List Explanation - City of Fort Collins

Front Range Tree Recommendation List
In 2010, a group of individuals evaluated and rated over 250 trees or varieties growing
along the Front Range. Each tree was given a rating of:
A – Generally Recommended
B – Conditionally Recommended
C – Potential/Unproven
D – Not Recommended
The Front Range Tree Recommendation List with descriptions of the ratings can be
downloaded from CSU Extension at www.ext.colostate.edu/pubs/garden/treereclist.pdf.
Notes
1. Select trees from the “A list” (Generally Recommended) or the “B list”
(Conditionally Recommended) where the limiting critical factor(s) can be
managed.
2. When selecting trees from the “C list” (Potential/Unproven), use limited
quantities appropriate for the site.
3. Do not use trees from the “D list” (Not Recommended).
