Dark green circles represent the "outer," highly visible trees. These must look like the classic vase-
shaped American elm. Light green circles represent the "inner," less visible trees. These may deviate
slightly from the classic vase-shaped American elm.
When the UHI team inventoried the trees in June 2017, essentially 100% of the trees were American
elms. They also recorded approximately 30 potential planting sites (empty spaces in the grid).
Planting trees in the 30 open spaces would start adding diversity in the first year: 95% American elm,
3% Group A trees, 2% Group B trees. (figures continue on the next page)
