American Residential Macrosystems - Lawn plant data within residential yards in seven major metropolitan areas, 2012-2015

"In seven major U.S. metropolitan cities (Boston, Baltimore, Los Angeles, Miami, Minneapolis/St. Paul, Salt Lake City, and Phoenix), 1m2 plots were sampled in residential front and backyards, as well as nearby natural areas, in order to evaluate the plant community composition, diversity, and percent cover of plant species. In addition, in Los Angeles and Salt Lake City, full yard plant communities were also sampled for a plant community of the entire yard. "
