Photos of the Week – August 27, 2021

If you’re a podcast listener and on the lookout for prairie-related content, I’m a guest on two different podcasts that came out this week. The first is The Prairie Pod, a terrific podcast sponsored by the Minnesota Department of Natural Resources. On the episode I was part of, Megan, Mike, and I talked about habitat heterogeneity – why it’s important and how to create it. The second podcast is called Science for the Rest of Us and host Alex McKiernan and I covered just about everything you could imagine related to prairies in an hour and a half.

In other news, my wife Kim is training for an ultramarathon later this fall. Last weekend, I drove her to and from southeast Kansas so she could do some long training runs on the rocky trail the race will take place on. While she did her obscenely long trail runs, I wandered much more slowly around with my camera, trying to find something to photograph. The dense woodland along the trail and the weedy, brushy habitats nearby didn’t provide much for flowers or pollinators, but spiders were all over the place. That was ok with me, I like spiders just fine.

Below, you’ll see photos of some of the little friends I ran into. Kim ran into many more – literally – while she was running the trail. She had to comb all the silk and detritus out of her hair afterward (her reward for being the first out on the trail each morning!) My encounters were much less dramatic, both for me and the spiders. I know not everyone is a fan of spiders, but I think they’re beautiful and fascinating creatures. I can’t identify most of the species, but I’m guessing some of you will be able to.

I think this is a banded argiope. Nikon 105mm macro lens. ISO 500, f/10, 1/400 sec.
This banded argiope was feeding on a leafhopper. Nikon 105mm macro lens. ISO 500, f/20, 1/125 sec.
Spider and moth. Nikon 105mm macro lens. ISO 500, f/14, 1/80 sec.
Ok, this isn’t a spider, but this assassin bug was caught in a spider web and I grabbed a few photos of it when the spider saw me coming and retreated to the corner of its web. Nikon 105mm macro lens. ISO 500, f/11, 1/60 sec.
This black and yellow argiope was a little bigger than the banded argiopes, but both sat nicely while I stuck a macro lens into their faces. Nikon 105mm macro lens. ISO 500, f/18, 1/160 sec.

Summer Fire Follow-Up

My post on our August 12 prescribed fires generated a lot of interest and comments. I’m glad the post was interesting to people and I was once again gratified by the tone and content of the comments. This blog has over 5,000 subscribers and many others that read it, and yet I’ve had incredibly few problematic comments and commenters over the years. Thank you for that.

Since there was so much interest, I thought I’d provide a quick update on the fire today. The photos here were all taken earlier today. We’ve put up some small exclosures that will help us gauge the impact of the immediate grazing on the vegetation – both this fall and into next year – and will be doing some quantitative evaluation of woody plant impacts. Those results will have to wait, but these photos can at least give you a brief look at how the burned areas look 11 days after the fire. All these photos are from the second unit we burned last week, a former cropland planted to high-diversity prairie in 1994.

Grasses are quickly popping back out of the ground after the fire. That includes both native warm-season grasses like Indiangrass and non-native grasses like smooth brome. In this photo, you can see that ants have also been active, but I’m not sure whether that’s related to the fire.
Cattle have had access to the burned unit since the day of the fire. Their tracks are all over the burned area but I’m not sure they’ve done much feeding that. That should change as the grasses get just a little taller than the 2-4 inch heights most are at now.
These dogwoods were top-killed by the fire, but I anticipate seeing resprouting from the base of most of them either later this year or in the spring.
There were around a dozen small eastern red cedar trees in the unit, including this one, which was about 3 1/2 feet tall. They all look nice and dead.
Grass growth is looking lush and green, though still pretty thin this early on. We’ve had some good rains, both before and after the fire, so that’s helped spur growth.
Maximilian sunflowers are sending up new shoots from basal buds, just like the grasses are.
The combination of bare ground and lots of light has triggered germination of some species, including thousands of these tiny Illinois bundleflower seedlings.

I’ll try to continue updates as the year goes along. Thanks again for the productive discussion that has arisen around last week’s post. We’re all experimenting and learning, so the conversation is productive for me and I hope it’s helpful to you as well. I really do appreciate this community.
