HABITAT TYPES AND PLANT COMMUNITIES : 
Green ash has been used as a climax indicator in a number of forested
habitat typing systems in the central and western part of its range in
portions of Montana, Wyoming, North Dakota, and South Dakota.  The
understory dominants used as indicator species within the green ash
series are common chokecherry (Prunus virginiana) and western snowberry
(Symphoricarpos occidentalis).

Green ash also forms co-climax stands with American elm (Ulmus
americana) with common chokecherry as the understory dominant, and is a
dominant overstory component in various deciduous forest and woodland
plant association types, including:  Rocky Mountain juniper (Juniperus
scopulorum); bur oak (Quercus macrocarpa); eastern hophornbean (Ostrya
virginiana); aspen (Populus tremuloides); and plains cottonwood (Populus
sargentii) in North Dakota, South Dakota, Nebraska, Montana and Wyoming.

Published classification schemes listing green ash as a climax indicator
are presented below.
