I have divided the season into
1) Pre Isaias,
2) Isaias affected incubation, and
3) Post Isaias.

1) Nests 9-14 were excavated on I-day because there had been hatchlings or signs of hatchlings. So all nests 1-14 had survived the June weekend of 16 inches of rain and while success wasn’t the greatest, they were all in the water

2) Nests 15-62 were all in the ground on I-day. Day after the storm some were still marked, some were located by visitors, some were located by animals, some were barely under the sand, some were so deep we nearly lost the excavators, some nests were lost. Some of the lost were washed away. Some of the lost were just never located. Some of the located nests had less eggs after the storm than before. Some of the lost were probably just too deep for us to find. Some were so compacted in the sand that hatchlings were odd shaped.

3) Nests 63-65 were laid after Isaias but nests 63 and 64 were overwashed during the king tides Sept 20-23. Nests 66 and 67 were wild nests that were high in the dunes and survived all the elements.

2019 Season Beginning Soon

The 2019 Turtle Season is almost here!  Beginning May 1st, the Turtle Watch Morning Patrol will search Caswell Beach for any tracks left by a mother turtle who might be laying eggs.  If a nest is discovered, it will be marked and assigned a sequential number, starting with 1.

With the beach re-nourishment project behind us, we look forward to a “normal” turtle season.

New Season Starting Soon

The 2017 Turtle Season is almost here!  Beginning May 1st, the Turtle Watch Morning Patrol will search Caswell Beach for any tracks left by a mother turtle who might be laying eggs.  If a nest is discovered, it will be marked and assigned a sequential number, starting with 1.

Hopefully 2017 will continue the trend of increasing number of nests as experienced in the previous 2 years!
