Yay! Fishies Again!

Written on: May 8th, 2018 in Education & OutreachGuest BlogSt Jones Events and ProgramsSt. Jones Reserve

DNERR always offers something unexpected, and recently, one needed only to look overhead to see it. In the lab at the St. Jones Reserve, dual clotheslines were strung with, no, not freshly laundered lab jackets or drip-drying dip-nets, but damp sheets of colorfully daubed paper. The sheets overflowed onto many of the nearby horizontal surfaces.

Though I had already experienced Gyotaku, the Japanese art technique known as fish printing, this guest-blogger did not realize DNERR offers different fish-printing opportunities for the smaller fry among us. The large, rubber fish used by teens and adults can be too much for little hands, I was told, and hence these smaller fish-print stamps.

I eyed the array of creatures — who, in turn, looked right back at me — and found the smiling jellyfish irresistible for its quirky, almost paradoxical combination of hidden danger and overt insouciance.

Headlines in late 2017** announced that a University of Delaware professor, along with a UD grad who’s a researcher at the Smithsonian Institution’s National Museum of Natural History, discovered that a type of jellyfish in our region that has long been thought a single species is in fact two: the U.S. Atlantic Sea Nettle (Chrysaora quinquecirrha) and the Atlantic Bay Nettle (Chrysaora chesapeakei). The moral of that story? Even for the experts, there is always more to learn about this big world around us.

The moral of this story? Whether one species or two, those jellies would not take kindly to being dipped in paint and then pressed onto blank art‑paper; so the child-friendly stamps are a great way for kids to interact with these particular marine denizens without incurring “The Wrath of the Chrysaora,” a type of 3-D, sensory, theatrical experience no one wants to have — the jellies included.

Dancing with Horseshoe Crabs, Under the Stars

Written on: March 27th, 2018 in Education & OutreachGuest BlogResearchVolunteers

Do you recall the mention, in this blog, of the “poetry in Horseshoe Crabs”? (If not, just keyword-search “poetry” on this page.) Now is your chance to prepare for experiencing that poetry for yourself, when “dancing” with the crabs during a real-life beach “party” in support of a good cause: DNERR’s annual Horseshoe Crab Spawning Surveys.

DNERR has several upcoming Horseshoe Crab Survey Training Sessions, in advance of the actual surveys that will be conducted from late April through early July. This year’s training sessions are:
Saturday, April 7:  10 am – Noon, and 2 pm – 4 pm
Further details can be found by clicking here.

Signing up for a training session, and then being a participant in a count, are great ways for everyday citizens to assist with the advancement of science!  Participating in a Horseshoe Crab Survey is an opportunity to attend a special type of late-night “party” on the beach, at high tide, and to have the privilege of “dancing” around the spawning Horseshoe Crabs while standing under a canopy of stars. Each group uses a portable quadrat for a “dance floor,” its boundaries delineated with a framework of PVC piping. 

This guest-blogger crossed paths recently with DNERR’s Horseshoe Crab Spawning Count Coordinator, Drexel Siok, and with DNERR’s Research Coordinator, Dr. Kari St. Laurent, for the purposes of learning more about the program. Drexel has been coordinating the counts, he said, for about five years.

“We always need new people to help out; but those who have previously completed the training must still come back every three years in order to stay current with procedures.” He continued, “Right now, we are looking for 75 people to participate in the training sessions. The registration for the sessions is done online.”

Kari, noted, “Some of the volunteers come from a distance, such as New England; so they are not necessarily all local people.” Clearly, all are driven by a love for the cause. “We also get a decent amount of school kids, of middle-school and high-school students.”

The training sessions typically cover topics such as biology and management, and they address such questions as why conduct the surveys, who uses the data, and what can — and cannot — be inferred from the data. Drexel and Kari agreed that, “Drawing accurate inferences is not that easy.”

“For instance,” Drexel explained, “Horseshoe Crabs reach full maturity at 8 years. That is the point at which they start to come up on the beach. So any changes to harvesting policies might not show up for a while in the count data. The spawning survey is also a measure of just the crabs we can see on the beach, and not necessarily the entire population.”

Kari added, “That is also why it is important to look at whole Delaware Bay-wide picture, not what is happening at just one point, on one particular beach, in Delaware.”

As an enticement to would-be survey-participants, she cited the fact that, “The U.S. Fish & Wildlife Service has a Horseshoe Crab tagging program. Watch for those tags! If you spot one on a crab, and report its number, you can receive a pin [as a prize].”

Drexel noted, “Hundreds to thousands of Horseshoe Crab tags are affixed per year. We have seen maybe 10 or 15 total in our surveys.” It pays to be observant, and therefore DNERR’s having the extra pairs of human eyes out there is important in more ways than one.

“We need a significant amount of people each night of a count,” Kari noted. “Otherwise, that is a data gap we can never get back. We really rely on our interns and volunteers for assisting with these counts.”

Can we rely on YOU to help? Please let us know!

New faces are at the DNERR!

Written on: February 12th, 2018 in Blackbird Creek ReserveEducation & OutreachNERRSt. Jones Reserve

We would like to formally welcome and introduce (although a little delayed) our new Environmental Program Manager and Assistant Reserve Manager, Lara Jennings, and our new Assistant Education Coordinator, Rebecca Vermeesch!

Lara Jennings, Environmental Program Manager

Introducing Lara Jennings

Lara joins us as the Environmental Program Manager and Assistant Reserve Manager from the DNREC’s Division of Watershed Stewardship where she spent eight years in various positions including Wetland Field Technician, St. Jones Watershed Coordinator, Environmental Scientist with the Nonpoint Source Program and a Program Manager for the Drainage Program.  She also spent time as an Outreach Specialist with the Division of Fish and Wildlife to help promote wildlife habitat conservation on private lands.  Lara received a Bachelor’s degree from the University of Delaware in Wildlife Conservation where she completed undergraduate research as well as study abroad programs to Costa Rica and Tanzania.  She clearly brings a lot of experience and eagerness to the Reserve, we are excited to welcome her aboard.  In her free time, she enjoys hiking, traveling, visiting the beach, and spending time with her family on their farmette.   




Rebecca Vermeesch, Assistant Education Coordinator

Introducing Rebecca Vermeesch

Rebecca joins us as the Assistant Education Coordinator from DNREC’s Division of Fish and Wildlife where she worked at the DuPont Nature Center educating visitors of all ages about horseshoe crabs and shorebirds.  She has a B.S. in Marine Biology with a dual minor in Environmental Science and Fisheries Science from Rutgers University.  Her college internships working at summer camps, non-profit organizations, and an aquarium has given her experiences in education, research, and interpretation.  Rebecca joins our team with a lot of enthusiasm and a love of horseshoe crabs, so we think she will fit right in with our crew. In her free time, she likes to kayak with her sister and take her dog, Bella, to the beach. 

We are excited to welcome these lovely ladies to the Reserve and look forward to what they will accomplish in the future!
