Join the Watch Hill Conservancy for the 20th year participating in Project Limulus, a scientific survey tracking horseshoe crab populations. Experience these “living fossils” up close while contributing valuable data to this long-term research program. Participants  should be prepared for the physical demands of the survey and must be at least 12 years old to volunteer. A maximum of six volunteers can join per survey. Please sign up for no more than three survey dates to allow others to participate. Surveys are conducted during the high tide of new and full moons during May, June, and July, as this time is when horseshoe crabs are most likely to come ashore to spawn.
