2010 Horseshoe Crab Spawning Survey
Volunteer Training to Be Offered April 10 and 28 at the St. Jones Reserve
The Delaware National Estuarine Research Reserve (DNERR) is seeking volunteers to assist with the annual baywide horseshoe crab spawning survey in May and June on Ted Harvey Wildlife Area, Kitts Hummock and North Bowers beaches.
Since 1990, surveys have been conducted of horseshoe crabs spawning in Delaware Bay. Despite the horseshoe crab’s importance to the ecology of the Bay, little is known about its population status. The data collected by volunteers during these surveys is key for scientists to monitor changes in numbers of spawning crabs in the Bay. Now, every spring on several peak spawning days, volunteers donate their time to count crabs on key beaches in Delaware and in New Jersey. Delaware’s well-trained and enthusiastic volunteers have made this program one of the most successful volunteer-based wildlife surveys in the country.
DNERR staff will host two volunteer training sessions for those who are interested in assisting with this year’s survey at the St. Jones Reserve, 818 Kitts Hummock Road, Dover. New volunteers and past participants are both strongly encouraged to attend one of the two sessions.
• 10 a.m. to noon, Saturday, April 10
• 6 – 7:30 p.m., Wednesday, April 28
Volunteers will learn how to conduct the survey, how to properly record data and how to distinguish between male and female horseshoe crabs. The training will also highlight results of horseshoe crab survey data and how it is being used.
In addition, training participants will have first preference for beach and date signups for the DNERR coordinated beaches. Participants who are interested in other Delaware Bay beaches not coordinated by DNERR are welcome to attend the training and will be referred to the appropriate beach leader for further information. Volunteers under age 18 must be accompanied by an adult.
