Each time we explore a Greater Lovell Land Trust property, we have no idea what we might discover and this day was no different. For today’s Tuesday Tramp I suggested we visit the Cohen Property near the Lower Bay of Kezar Lake, which was the last acquisition under the direction of the late Tom Henderson. We’d only been there once before–and that was a few months ago when we explored via snowshoes. At that time we discovered ice-covered depressions and so a journey to check them out as vernal pools seemed apropos.
There are no trails yet and so after parking, we followed the road back a ways to the area of our winter expedition. And what to our wondering eyes did we spy on the road? Moose prints! One should always look through a magnifying glass to make certain the ID is correct. Wes confirmed our suspicion.
We found sitting water and running water and began to wonder about the wetland and whether what we thought might be a vernal pool really was, for we knew that a v.p. shouldn’t have an inlet or outlet. As the first dips of the day were made, black flies began to swarm around us. We hoped to pick up their larvae in the moving water, but instead we found many springtails.
And a few mosquito larvae as determined by Caleb, Linda and Nancy.
In another spot, we also found a mystery. At first we thought it might be some sort of egg. And maybe it was, but how was it related to the algae that seemed to be a host? We didn’t know, but now that we’re aware of it, we’ll continue to wonder and perhaps become enlightened.
We checked out “pool” after “pool” and found not one egg mass (except for a false start that fooled us momentarily), which rather disappointed us. Were these really vernal pools? We suspected so as they were shallow and looked like they’ll dry up in the summer, if not before, plus they supported no fish. Were they significant vernal pools? Definitely not. To be a significant vernal pool, the body of water must contain one of the following obligate species: 1 fairy shrimp or 10 blue-spotted salamander egg masses or 20 spotted salamander egg masses (yellow spots) or 40 wood frog egg masses. Fairy Shrimp? No. Salamander egg masses? No. Frog egg masses? No.
Despite the lack of indicator species, we scooped up water to determine what did live there.
The most abundant residents found–mosquito larvae. And do you see the small jar in Ellie’s hand? She created a mosquito larvae aquarium and discovered that they seemed to like the algae she’d added. Perhaps they’d found microorganisms we couldn’t see.
Watching the acrobatics of the larvae entertained us for a while. They twisted and turned somersaults and wriggled in the water and we soon realized that eggs left behind by last year’s females who had sucked our blood before breeding, must have remained dormant all winter until the snow melted and spring rains began.
We did find another species to admire, that also wriggled in a constant state of contortion–this one being a chironomid midge with blood-red coloration. According to A Field Guide to the animals of Vernal Pools, the color is “due to a hemoglobin-like pigment that helps them retain oxygen. This pigment allows the larvae to survive in water that is very low in dissolved oxygen, as is common in vernal pools as drying proceeds throughout the seasons.”
Because I had to meet someone at noon, and Dave knew that it would take us at least a half hour to make the short trek back to our vehicles due to our incessant nature distraction disorder, we had to cut our journey short. Dave was right–as he often is–and we were forced to stop several time, including to sniff a couple of mayflowers, aka trailing arbutus or officially: Epigaea repens.
We finally reached the spot where we’d parked with fifteen minutes to spare when Linda sighted movement beside the tires of my truck and our hearts jumped with joy.
We didn’t want to run it over as we backed out and so Heinrich captured it. What is it? An Eastern ribbon snake, which is a species of special concern in Maine. According to the Maine Inland Fisheries and Wildlife website, “A species of special concern is any species of fish or wildlife that does not meet the criteria of an endangered or threatened species but is particularly vulnerable, and could easily become, an endangered, threatened, or extirpated species due to restricted distribution, low or declining numbers, specialized habitat needs or limits, or other factors. Special concern species are established by policy, not by regulation, and are used for planning and informational purposes; they do not have the legal weight of endangered and threatened species. The Maine Department of Inland Fisheries and Wildlife reviews the list of special concern species at the beginning of each calendar year, and, based on criteria in the Maine Endangered and Threatened Species Listing Handbook , revises the list as appropriate.”
And that is why it’s so important to protect the land. I knew Tom was smiling down upon us due to this find. Interestingly, we also spotted a ribbon snake at the John A. Segur Wildlife Refuge on Farrington Pond Road in early May 2015.
Finally, we all departed and I was only ten minutes late for my quick meet-up, after which I headed back down Route 5 to reconnect with my favorite little naturalists at the Kezar River Reserve across from the Wicked Good Store. There’s a tape across the road, which I suspect was put in place by the local snowmobile club when the ice was questionable on the river, but it remains, which given the recent rain is probably a good thing. We’ll take it down soon, but it has prevented the road from becoming more rutted than normal.
Anyway, Wes climbed out of the family’s vehicle with his paper birch armor. He’d spied it in a V between to birch trees on our morning trek and his mom climbed up to retrieve it for him.
Birch Man posed again and again, until his older brother Aidan, sporting a missing front tooth, jumped in front.
The boys stood on a hump of earth beside a tree root. And it was through their eyes that we noticed some interesting finds among the tree’s former life support.
We found pottery and cast iron and realized the tree had grown upon an old dump site.
And that hump of earth–the four siblings were sure that it hid a Volkswagen Beetle.
It took us a while to walk down the “roadway” and then the left-hand loop. We made a few discoveries, including coyote scat filled with bones, and the kids did some trail work. At last we reached the canoe/kayak landing at the Kezar River and noted some otter scat and a few slides, plus some fishing lures and line stuck in the trees. It was at that point that the family had to leave, but before they left they asked me what I’d do before I had another meeting in the afternoon. I told them I planned to hike the second loop, which happens to be longer and dips into an interesting ravine.
That never happened. As it turned out, I stood at the boat launch for about an hour. First, I spied one small clump of salamander eggs.
And then realized that the raft before me, which filled the small cove, was equisetum. Where it came from I didn’t know for I couldn’t recall ever seeing it at this property.
But, regardless, it provided a perfect camouflage for aquatic insects. It took me a while to key in on the species before me, but I knew they were there because every once in a while, one took flight. Do you see the mayfly subimago that had recently emerged? The teenager stood atop its nymph exuvia. Mayflies are unique in that after the nymph emerges from the water as the subimago (that fishermen call a dun), they seek shelter before shedding their skin for the final transformation.
I really had to focus in order to spot them.
But once I did, they were . . .
And in all forms, including a nymph.
The cool thing is that thirteen mayflies are also on the list of species of special concern. Was this one of the species? I have so much more to learn.
As I continued to watch, there was an incredible amount of activity. And then I saw a predator that was about two and half inches long. Do you see it? Not atop the vegetation, but rather under it in right-hand center of the photo. Behind it, almost to the right edge of the photo, was a bubble at the end of its long breathing tube.
As I watched, it continued to swim forward, the vegetation providing it’s favorite type of habitat. Again, you have to look carefully.
And again. It was a water scorpion with an oval-shaped abdomen. Do you see it?
Finally, it was time for my next meeting, but as I walked back up the trail I reflected upon the wonders of the day and the work of the land trust under Tom’s leadership. Creating corridors is important for mammals, but also for all critters that share the various habitats.
There was no need to put out a distress signal today. Indeed. With others and alone, I was thankful for the opportunity to be gifted with such sightings: Mayflowers and Mayflies! And a water scorpion. Topped off with a ribbon snake. May Day Alert of the best kind.
