This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.

This is a weedy grass that thrives in disturbed ground, including cropland and roadsides. It has expanded east and north into new habitats created by humans, contiguously with its native range. The Arizona population we mark introduced because it is separated from the rest of the range by a large distance. There are also isolated introduced populations in Mexico not yet reflected on our map.
