I-Rank Reasons Summary: Prunus avium reproduces on its own throughout northeastern and midwestern North America and also in the Pacific Northwest, especially along fencerows, roadsides, and in open woods. There is a question as to whether it is naturalized in California. Apparently, most of its impacts are in Washington and Oregon, however, more information is needed. In the southern Williamette Valley of Oregon, Prunus avium has a high impact on native vegetation. It forms large monocultures (or near-monocultures), severely modifies natural habitats, and shades out forest understories. In the Willamette Valley Prunus avium is a dominant in the sapling layer of some Quercus garryana forests. At least some of these forests are of conservation significance. More information is needed about its ecological impacts across its range and its management difficulty.
