Last Saturday morning was a busy one for a small group of El Camino Real Texas Master Naturalists. The intrepid seven started out attending some previously girdled trees and finished by photographing everything they could find for the “Hotter than Hell BioBlitz” at Wilson-Ledbetter Park in Cameron.
Original girdlers of the invasive Glossy Privet Liz Lewis, Marian Buegeler, and I did some follow-up work on the trees we originally performed girdling on back in March. Marian was armed with a hatchet and I had a tree trimmer device to remove any new growth below the girdles. Liz directed.
I was surprised to find the trees dying because an inspection a month ago didn’t really show any significant dying off. They are showing plentiful evidence of their demise now. In case you’re new to this subject, tree girdling is a method to kill trees without herbicides or chain saws. You can find directions on how to do it from the March blog if interested.
The drought and excessive heat may be hastening the death, but it’s all occurring above the girdle line, so the process works. We are now a little excited to see where they stand in late fall.
We then proceeded to photograph what was still alive in the drought/heat wave at Wilson-Ledbetter. We managed to get 208 photos of nature surviving the weather. “Birdladymilam” Ann Collins posted the most photos on the project page on iNaturalist. Eric Neubuer found the most of one species (Wolf spiders in case you weren’t sure). Organizer Linda Jo Conn, Marian, Victoria St John, Liz and I also contributed. Blooming flowers were sparse, but there were a lot of trees, vines and grasses along with spiders, and birds.
This was a low-key BioBlitz, promoting observations made at one’s place of residence to avoid travel and promote physical distancing during this time of COVID precautions. We enjoyed pleasant weather that encouraged outdoor time during the first part of the designated week, but it did get a bit disagreeable during the last days. Still, worthwhile observations were made.
Perhaps one of the first things noticed by plant observers was the lack of blooms. Yes, there were the typical cool-weather blossoms of henbit deadnettle, catchweed bedstraw, shepherd’s purse, and common chickweed, but also a lot of unidentifiable leafy green rosettes.
Lichens, particularly the orange colored hair lichens, were definite eye-catchers in the drab landscape.
Some plants such as the American Trumpet Vine were identified by last season’s seed pods
Other plants were given a general tentative ID and hopefully will be revisited when blooms appear later in the year.
We observed birds. A Red-Shouldered Hawk is perhaps checking out the nearby martin house.
We observed reptiles. Well, one reptile observation was made.
We saw mollusks,
And other arthropods, such as this intact exoskeleton of a white river crayfish.
So, I thank you, sunasak, birdladymilam, marianmarie, eaneubauer, chenderson, dsorenson, potterswasp, jfcthornton, and debbi9, for participating in the BioBlitz.
I look forward to joining you at the spring iNaturalist seasonal BioBlitz, scheduled for May 20-26.
Way back when TMN training was beginning, I heard Alan Rudd’s stories about little grasshoppers that jumped into the water to eat algae or escape with interest. Over the next year I encountered pygmy grasshoppers in just three places, locations including Taylor Park on Granger Lake on Day 1 of the Bioblitz.
On Day 3 I encountered some again, this time at Alan Rudd’s place, where I had seen some in the fall. It seems they remain active through winter in very sheltered areas. Unbelievably I ended up with a mating pair sitting on my finger, something that isn’t likely to ever happen to me again.
How did this happen? I saw one sitting near the water and tried to scoop in up in a container I had along for photographing Pardosa spiders. Of course, being a grasshopper it immediately jumped out as I expected, but landed upside down in wet mud, and I could see her tiny feet waving around in the air. So I offered her my finger, which she grabbed onto and was happy enough to sit there while I took as many photos as I wanted.
As I started taking photos, I realized there was more than just mud stuck to her. Eventually I realized it was an entire male grasshopper. When I finished with the camera, I put the grasshoppers back where they came from.
A little later I thought I saw a grasshopper jump into the water and burrow in the mud. I wasn’t sure, because little frogs were doing exactly the same thing to avoid me. I took a photo, and sure enough it was a grasshopper, proving that Alan hadn’t been exaggerating.
Whoops! After carefully looking at the supposed Paratettix hiding in the mud, I believe it is actually a frog, Acris blanchardi, so my underwater photo of Paratettix hasn’t happened yet. You’d think it hard not to be able to tell a grasshopper from a frog, but there you go. I’ve deleted the observation and resubmitted under Acris.
Linda Jo commented that this isn’t the first time such a mis-identification has occurred!
We will be celebrating Valentine’s Day soon and at my age that doesn’t mean a dozen roses or a box of candy from a six-foot good-looking guy! It is a time that gives me pause to think about the appreciation I feel for a group of people.
I appreciate the value system of our Master Naturalist group. There has been due diligence in protecting us and still providing opportunities. On the state level, the Virtual Volunteer Fair was awesome, but the event impacting me the most is joining the Winter BioBlitz. Linda Jo has been such a supporter for all of us in participating in iNaturalist, but I always found an excuse.
Excuses including: I need a new iPhone, more books, more expertise…
First time out I came back with my photographs and spent hours pouring over plant identification references. I don’t regret the time spent, but it was overkill when you have Linda Jo checking your work! I ended up with three research-quality entries (my yaupon holly is shown below), and you would have thought I had just gotten a gold star on my research paper. ( Please do not ask me about lichens or mosses though.) I encourage anyone hesitating to take the big step, take it!
So, to all of you that have worked so hard to keep us active, safe and appreciated, thank you and Happy Valentine’s Day!
Investigating the Granger Lake area is something I’ve been meaning to do for more than two years. There are over a dozen access points, so this was no small task, and I still had several to go when I stopped for the day. Although it was warm, few animals were stirring and it wasn’t until the fourth stop that I found anything noteworthy. That was the area called eOSR 3, which I suspect refers to further information on-line.
As I approached the parking area on CR 349, the road crossed a mostly dry deep ditch with a pebbly bottom. I immediately thought I might find some Stone Spiders (Pardosa lapidicina) there. I had recently encountered all four Pardosa species in the milvina group over in Burleson County and that left just four more Pardosa species to find in this area. It was my lucky day, because nature was unusually predictable. Nature even gave me a bonus as a Burrowing Owl flew up and sat on a fence post as I picked my way down into the ditch.
End of the story with the Stone Spiders? Not quite. After I got home I looked up photos of Pardosa lapidicina on iNat and BugGuide, and mine didn’t look sufficiently identical. There are three Pardosa spiders in the lapidicina group in the area, so I figured it must be one of the other two. After consulting a few scientific papers, I’ve tentatively identified mine as P. vadosa, first described in 1959, for which there are no living spider photos on-line. I’ve asked for expert help and await a reply. Reading between the lines a little, the western edge of vadosa range may coincide with the western edge of the Blackland Prairie. Father west, mercurialis takes over.
In more spider news, I’ve been finding these Trochosa sepulchralis in a small part of ditch on CR 418 adjacent to woodland. These are my most recent of eight observations and include a male and a female. Identification is difficult, but at least there are fairly recent papers on them. Camptocosa, Trochosa, and Varacosa each include similar species. The differences are subtle, so I’m not sure if I got it right. Not sure if these are adults yet, but they appear to be close. Incidentally, this species was first described from Philadelphia PA where I was born.
Sue Ann’s Report
My report is nowhere near as fascinating as Eric’s, mainly because I only saw two insects other than fire ants, and they were too fast for me. I did get some nice photos of tiny flowers, and spent a lot of time puzzling over grasses, including once when I accidentally said a bunch grass was Bermuda grass. I’m sure that made Linda Jo laugh.
But it was a beautiful day, so I enjoyed seeing what there was lots of and what’s just poking out of the ground. There is lots of henbit deadnettle, that’s for sure. I’m enjoying seeing it cover whole fields, even if that bothers farmers.
I went a little overboard and made 72 observations, but was pleased to see that put me over 2,000 iNaturalist observations. And I sure know what’s growing around my property in early February now! I had a blast!
I do want to point out that other members of our Chapter have made fun observations, too. Marian, Linda Jo, and Carolyn also got out and checked out their surroundings. Please go to the project page to keep track of our activities, and let Linda Jo know if you would like to participate! Just because it’s a bit chillier doesn’t mean it won’t be fun to get outside. My phoebes are certainly goading me!
