What is it? Wow, look at that!

That is what you heard, over and over again, Saturday afternoon in the Conservation Education Center at Black Bayou Lake NWR as eleven excited Master Naturalist wannabees went through the contents of their collection pails. Our workshop leader, Dr. Anna Hill, went from microscope to microscope patiently answering our questions.

At the same time, Kris Kelley of FoBB sat behind a microscope hooked up to a camera and projector. We all took pictures of the critters in our petri dishes and projected on the screen, but the photos Kris took with the microscope camera are excellent. He created a cache of them on Google Docs for us. Click here and enjoy:

MasterNaturalist Aquatic Life June 2018

Note that one of the frames on that page is a video that has been uploaded to YouTube. Here’s a direct link to the video:

Master Naturalist Microscope Video

The point of interest in the video is the white, lacy critter in the upper half of the frame. Not much happens for the first 45 seconds, but then you will see the entire critter convulse as it responds to something in the petri dish environment–food, most likely! And from there to the end of the video, various parts of the “ciliate colony” react every few seconds in similar fashion. I hope it was having a good meal!

A species list will be forthcoming, but be forewarned that most of what we saw we could not identify to the species level. Nevertheless, we learned some categories, I satisfied my long-time desire to see dragonfly and damselfly naiads in living color, and all the critters were truly amazing to behold.

As we were preparing to empty our collection pails in the pond in front of the Education Center, I captured a little drama happening in mine. I had collected a fishing spider and a predacious diving beetle larva–a critter that looks about as scary as its name. It had kept its pincers closed throughout its several minutes of fame under the projecting microscope, but now they were open and the creature was turning its head toward the spider, which was on the surface of the water nearby. Of course, I have no idea what was actually going on in that pail, but it sure looked sinister!

And here’s a link to another cache of photos from the day, created by Charles Paxton:

Important Note: Black Bayou Lake is a National Wildlife Refuge. Collecting specimens from the lake requires a permit, which our workshop leader had gotten for us. To do this without a permit is strictly against the law. (BTW, Dr. John Carr also had to have a permit for his work with us a few weeks ago.)

We came away with stories to tell!

Our day began in a ULM classroom. Dr. John Carr patiently walked us through the major families of amphibians and reptiles of northeast Louisiana with the help of an illustrated PowerPoint and a couple of great handouts. We had many questions.

Armed with our new knowledge, extensive notes and phones/cameras, we then headed to Black Bayou Lake NWR and reconvened near the Visitor Center. We were greeted there by Ryan, McKenzie and Ben, Dr. Carr’s graduate students, and… two turtles!

One of the two was a Map Turtle (Graptemys sp.), who had been rescued off a road on the way to the Refuge. She was quickly determined to be bearing eggs that Dr. Carr and his students wanted to incubate and hatch for research purposes, so she was placed in water in a tub. By the time we returned from our field work, she had laid one egg in the tub!

The other turtle that greeted us at BBLNWR was a male Common Snapping Turtle (Chelydra serpentina). It was a scorching day and we were hot, but the snapper was hotter! We kept a healthy distance from his darting head and beak-like jaws while Ben held the turtle and Dr. Carr notched his shell for identification purposes before releasing him back into the wild.

Later, Dr. Carr and his students emerged from the swamp carrying a female Common Snapping Turtle (photo above), who was equally hot under the carapace! Of course, we also got to see Louisiana’s favorite Red-Eared Slider (Trachemys scripta elegans), plus a couple of skinks, and–momentarily–a tiny escape artist Eastern Narrow-mouthed Toad (Gastrophryne carolinensis).

A hardy handful of us returned to the Refuge at 8 p.m. and were met again by Dr. Carr, his graduate students and Dr. Kim Tolson, who will lead a mammals workshop for us later this year. Back down the trail we went, to be greeted first by a deafening chorus of insects. The closer we got to the lake, the more the frogs took over.

What a wonderful cacaphony! We heard everything from tiny cricket frogs to deep-throated bullfrogs and several sizes in between, including bird-voiced tree frogs, bronze frogs, green tree frogs and more.

Hearing frogs and seeing them are quite different things, but with many eyes looking and several people willing to leave the boardwalk and wade, we were also able to see and photograph several species.

Did I mention snakes and ‘gators? Yes, we saw those, too. It was a fabulous day.

This post was written by Charles Paxton:

The Louisiana Master Naturalist Northeast’s botanical workshop group convened at the Chevron gas station in Georgetown, right by the Kisatchie National Forest, an easy day trip from Monroe. We were blessed with very fine Spring weather.

The Kisatchie is exemplary of Louisiana’s amazing biodiversity, with at least 56 reptile, 30 amphibian, and a huge range of bird and plant species recorded. Our plant check-list for the event had over 480 species and we added to it over the course of the day.

I think it is fair to say that my brain is still reeling from the event. It will take a while to digest the wealth of information. I particularly enjoyed the way Dr. Allen gave us extra information about the plants we encountered, especially about their roles as food plants for wildlife and their human applications.

We encountered a great many different plants. Dr. Allen is very knowledgeable and his enthusiasm for the subject is contagious. He made a superb expert guide and was very patient with all our questions. Though his workshop did much to lift the veil of mystery and convey the wonder of these plants, we were keen to buy his book on wildflowers to follow this up and for future explorations.

It was great to spend a fun day of learning in the outdoors with a very nice and friendly group of people.

Kauffman’s addendum: We identified and talked about 46 species of woody plants, 61 species of herbaceous plants, 3 grasses, 1 sedge, 1 rush and 1 fern, a total of 113 plants! The species list has been uploaded to the “Observe…” tab of this website.
