Terrapins in the Shark River? Still unknown



There has been some discussion over the possibility of diamondback terrapins living in the Shark River. Shark River is located in Monmouth County, NJ; it is a relatively small and shallow estuarine basin with no data to support the presence of terrapins. This summer (July 2011), the Marine Academy of Technology & Environmental Science (MATES), Drexel University, and interns with Monmouth University's Urban Coast Institute will pilot a mark and recapture study to hopefully answer this question. We will be working the weeks of July 4, July 18, and July 25 to capture diamondback terrapins.

The first week of trapping was on the south branch of the Shark River basin. The tidal range is great with traps sitting well, then beached during low tide. We caught a large snapping turtle (pictured) close to Brighton Road on July 7. We will resume trapping on July 18 in the north where there is more promising terrapin habitat than in the southern branch.

The second trapping session produced no terrapins during week one (July 17), but we are now concentrating efforts in Shark River Hills off S. Riverside and East End Avenues. After a second full week of trapping, we failed to capture any terrapins in Musquash Cove. Here is what we can report for this project:
1. Not a single terrapin was spotted basking anywhere along the banks of the masrhes
2. Not a single sign of nesting or even predation on nests was observed
3. Not a single terrapin was spotted in the water (which is not the case at Island Beach where we see them frequently)
4. Although trappins produced a snapping turtle, no terrapins were captured using baited hoop traps (in 360 hours of trapping). Compared to Island Beach with 30 terrapins caught in 360 hours).

Therefore, we cannot say "terrapins are not in the Shark River:, however, if terrapins are present, it would be a small population to say the least. Thanks to the Monmouth University students who were dedicated and did an outstanding job this summer!

2011 LBI Nesting Update




Thanks to the many volunteers that attended our LBI Nest Watch 2011 Program on Sunday May 22. This is part of a nest relocation program scheduled for Long Beach Island at the Long Beach Island Foundation of the Arts and Sciences (LBIF). The Marine Academy of Technology and Environmental Science (MATES), Drexel University, and LBIF are conducting a project to identify nests, mark nests, and move nests that may be in areas with a high possibility of human disturbance. Nests that need to be relocated, will be moved to a hatchery at the LBIF in Loveladies, NJ. There will be an additional volunteer training session once terrapin nesting is underway! Thanks Marc and Jane for their work on June 2. Nicole M. moved a nest from a construction area to the LBIF on June 4. On June 6, Marc and Jane moves two nests and found one nest with 20 eggs in a clutch! This is the new high mark for Barnegat Bay. Today, June 9, another nest was moved to the Foundation. John is helping a female terrapin hit by a car on June 7 and rescued by Dave. Thanks Dave! Stay tuned for the predator project on High Bar Harbor with Kathy!

June 18 was a busy day, the High Bar Harbor Tax Payers Association heard from me and Kathy about the LBIF Project and the threat of raccoon predators. Marc and Jane have been doing a great job in relocating nests and working with Dottie in Barnegat Light. There are eleven nests in the hatcheries at LBIF as of June 18.
As of June 24, there are 15 nests at the LBIF hatchery. On June 24, we marked 8 females that nested at High Bar Harbor, Barnegat Light, and North Beach. Thanks to Jane and Marc for their tireless efforts in Barnegat Light, and look for Kathy's terrapin nest predator prevention project at High Bar Harbor.
Next on the schedule is our hatchling watch at the Foundation and recovery of emerged terrapins for release back to the wild. Contact John if you would like to survey the hatchery at the LBIF to check for emerged hatchlings. Nest #1 and Nest #5had hatchlings on August 9 and 10! Nest #14 produced hatchlings on Friday August 11 and Sarah called to report more on August 13. We've had over 64 hatchlings as per August 20, 2011. We excavated several nests on August 25, 2011 in preparation of Hurricane Irene. Of five nests, we were able to rescue 14 hatchlings. Nests #30 and #31 contained eggs that looked good. All other nests were assessed and hatchlings removed at the LBIF. We had a volunteer recognition ceremony on October 11 at the MATES school (see photo above) and we thanked our tremendous volunteers for their time and dedication to the conservation of terrapins!
