DistributionFraxinus latifolia is found on the west side of the Cascade Range from southwestern British Columbia south through western Washington, western Oregon, and northwestern California; and in central California in the Sierra Nevada.[1][2][3]DescriptionFraxinus latifolia can grow to {{convert|25|m|ft|round=5|abbr=on}} in height, with a trunk diameter of {{convert|30|–|80|cm|in|0|abbr=on}}. The compound leaves are pinnate, {{convert|12|–|33|cm|in|frac=4|abbr=on}} long, with 5-9 leaflets, each leaflet ovate, {{convert|6|–|12|cm|in|frac=4|abbr=on}} long and {{convert|3|–|4|cm|in|frac=8|abbr=on}} broad, and often show signs of disease and brown rot, even on otherwise healthy plants. It is dioecious. The fruit is a samara, {{convert|3|–|5|cm|in|frac=8|abbr=on}} long including the wing.[1][2]The Oregon ash prefers damp, loose soils, and grows from sea level to {{convert|900|m|ft}} in elevation, up to {{convert|1700|m|ft}} in the south of the range in California.
