Hi SMSciGr1,

Your coordinates are ever so slightly off from the Ducktrap River. Please leave the correct coordinates in the comments below and we will update them for you.

Thanks!

Greetings SMSciGr1!

Thanks so much for submitting your observation. Your field notes are very good, and your photos are clear. Best of all, your findings are correct! Despite the rippled edges of the leaf-like blades in the photos, this is NOT curly leaf-pondweed. I beleive you are also correct in identifying this specimen as ostrich fern. Well done! Thanks for keeping a careful eye out for aquatic invaders. Please keep us the good work!

Have a fun summer!
