Today I worked with Alison Leschen from the Massachusetts Division of Marine Fisheries mapping horseshoe crab spawning behavior on Swifts Beach in Wareham, MA. To do the survey, we mapped out a series of 5ft x 5ft grids along the shore and into the water. We surveyed the beach from end to end. We recorded if there were horseshoe crabs within the grid, tallied the totals, and Alison entered the information into the database.
