Monitoring the Spread of Fumaria capreolata in the US
It's interesting to watch the spread of this introduced species in the United States. The first occurrence was posted to iNaturalist in June 2002 in California. Since then (19 years ago), F. capreolata has spread along the entire West Coast of California and it can now be found in 4 other states.
Compare these growth charts with Fumaria muralis, which occurs in 10 states after its introduction in June 2012 (9 years ago).
