California started this community science project to document urban nature — now it’s taking over the world!
The World Series of urban nature is here.
The City Nature Challenge is an annual competition that mobilizes communities to document as many species of plant, animal and other types of critters in a four-day period. This year’s event begins Friday and closes on Monday.
