Saturday, Aug 25th, was
Cornell Herpetological Society's annual Hellbender survey in the Southern Tier. We use this trip as an introduction for freshmen to the society. We joined veteran herp researcher, Dr. Richard Bothner, (professor emeritus from St. Bonaventure, author of the
new NYS Herp Guide, and and an expert on
Thamnophis brachystoma, the rare garter snake whose world range is from the Allegany region to Pittsburgh), and NYS DEC biologist Ken Roblee. They have been monitoring the Hellbender populations in NY for years. The situation isn't good. The species may soon be elevated from its Special Concern status to Threatened or even Endangered in NY State. You wouldn't suspect it, the way Dr. Bothner and Mr. Roblee take us to one of their study sites and we quickly turn up beastly salamanders. However, these sites are some of the last remaining in the state where they occur in any numbers, so we took care to tread carefully. Last year, we had good success. We caught three individuals, including a big 20+ incher. Check out photos and commentary from last year
here.
Our first catch this year at Location A was a mid-sized Mudpuppy (
Necturus maculosus).
Not long thereafter, a massive Hellbender was discovered. I looked across the creek to see what the shouting was about, and saw a big, squirming Hellbender go flopping person-to-person as they scrambled to get a grip on it, then diving back into the creek and disappearing. Given that it was the one-that-got-away, I'd estimate it was at least 5 feet.... not really, but I think it was a least a 20-incher.
Flipping away!


A few more rock flips later, and someone netted a Hellbender successfully. This guy/gal was small - measured out to 10 inches. Everyone, including our guides, were quite pleased to see a young individual. Finding young Hellbenders has become a rare occurance at many locales. They thought this one was only four or so years old.
We found little otherwise at Location A, so we proceeded to Location B, where the water was flowing faster and clearer, and there were more rocks to flip. After about twenty or so minutes of coordinated groups working there way up the stream, we uncovered two big 'benders in quick succession. We kept them waiting in nets dipped in the running water to keep them oxygenated, while we took them through the data collection process with Ken Roblee.

'Bender Transfer. We placed it into a big tote with some water, inside a long tray to measure length in. Ken is talking about directly measuring the O2 levels of the Hellbender as they work on them, so they can monitor their oxygenation and stress levels.
Looks like a great time and very glad that you guys were able to find a few! Ok, now I need to spend time watching all your clips! Great job documenting the day!
ReplyDeleteGreat overview. That was definitely a fun trip. Saturday I happened to have a 15 hellbender day (+ an egg mass). All of them were 18in or under though. I'll have to take you to that spot sometime.
ReplyDeleteIn the next few days I'm going to try and figure out when I'll be able to make a visit to Cornell. I'll probably contact you soon.
Thanks guys. I heard about that day, Rex - fantastic! Was it in PA?
ReplyDeleteI interned under Ken Roblee last year as a SUNY Buffalo student, he's a great guy to work with. Did a search with his name and found this. Is there anything better than slogging your way through cool mountain streams chasing slimy vertebrates no sane people would touch?

Nope, nothing better at all... :)
