Help us document the distribution and abundance of horseshoe crabs during their annual mating season along the shores of the Chesapeake Bay in Calvert County and beyond!
Use iNaturalist to photograph and map your observations in a few easy steps.
You can also help verify other people's observations to improve our data quality, come to a scheduled horseshoe crab survey, or even hold your own event. You can also explore on your own.
Spread the word—it's a big area! The area includes the entire Chesapeake Bay Shoreline in Maryland, Virginia and Delaware. We are really interested in Calvert County sightings, but any observations along the Chesapeake are important.
