Even More Photos From The Same Square Meter of Prairie – Mid-Late September (Part 1 of 2)

Hey, guess what? I’m still hanging out at my square meter photography plot.

September has been a month of big changes within the little bit of prairie I’ve been photographing all year. The month started with a flush of Maximilian sunflower blossoms and lots of bees, flies, beetles, and other pollinators. Then, I went to Illinois for a few days. When I got back, the sunflowers were pretty much done. Pitcher sage continues to bloom, but only a few flowers are open each day and it appears to be nearly finished.

I wanted to start this post by showing you where this little square meter plot is located. Lincoln Creek Prairie is about 14 acres on the eastern edge of Aurora, Nebraska. The park is bordered by crop land, housing developments, the local adopt-a-pet facility, and the city waste site. My little plot (circled in black on the two aerial photos shown here) is in a small strip of restored prairie nestled between a line of trees and some mowed grass leading to the waste site. I walk past the barking dogs at the pet adoption center whenever I visit my plot.

I took this photo when Maximilian sunflower was in peak bloom within my plot. It had already started to wrap up blooming in other nearby areas of the prairie.

It’s been about three weeks since I shared photos from this project. Within that time period, though, I’ve taken way more good photos than will fit in a single blog post. As a result, I’m splitting today’s post into two parts. Part one (this one) will focus on the general appearance of the plot and its inhabitants/visitors. Part two (not this one) will be more story-based. The photos in both posts cover the period between about September 8 and September 25, 2024.

Sunflowers have been done blooming for a couple weeks now. It was fun while it lasted, but there was also a lot of beauty in the waning of the flowering period. I took a lot of photos of the sunflowers as they wilted. Here are three examples.

Most of my recent visits to the plot have been in the early morning. I especially enjoy the mornings with a few diffuse clouds along the horizon and calm winds. I have to wait about 20 minutes or so after sunrise before the sun pops over the trees in the distance. On cloudless days, the sun is already pretty bright by that point and my opportunity for good photo light is pretty brief. With some diffuse clouds, though, that period is extended quite a bit.

The leaves of wildflowers in the plot have been dropping quickly, starting toward the bottoms of the plants. Maximilian sunflower, butterfly milkweed, and common milkweed, especially, have been self-pruning themselves. That’s changed the appearance of the plot substantially, making it a lot easier to see into and through the lower portions of the vegetation.

As I said earlier, pitcher sage has been the last flower to continue blooming. It hasn’t drawn as many pollinators as I’d expected, but it sure gets a lot of bumble bee visits. I’ve definitely seen other insects visiting it, including a sphinx moth that comes well before there’s enough morning light to capture any photos of it. I still haven’t photographed an adult butterfly in the plot this year, though, and I figured pitcher sage would have given me my best chance. There was a week or two when monarchs were abundant on pitcher sage nearby, but I never saw one come to my pitcher sage.

Much of the pitcher sage seed is already ripe, even while a few new blossoms are appearing here and there.
All the grasses have moved into seed mode, including this switchgrass.

Butterfly milkweed is producing a lot of seeds in my plot this year. That’s a stark difference between this year and my initial attempt at this project in 2018. In that first year, only one seed pod was produced, so every seed was precious to me and I worked hard to photograph as many as I could.

This year, I’m still enjoying all the seeds, but there are a lot of pods and a lot of seeds, so I worry less about when a particular pod might open and release its contents. My next collection of images (not part 2 of this post, but the one after that) will probably have a lot more milkweed seeds featured in it. This last week of September and the first week of October looks like they’ll be the peak time for those seeds.

Butterfly milkweed seeds are starting to fly around the plot.

Invertebrate activity has dropped off significantly in the last few weeks. There’s always something moving around during my visits, but I’m not seeing the kind of frenetic activity I experienced when the sunflowers were still yellow and morning temperatures were warmer. That’s ok. It gives me time to do more thorough searches and to spend a little more time with each little creature I find. You’ll see the results of that in part 2 of this post.

So far, I’ve got about 2,400 good quality images from this project. About 350 were taken during the Sept 8-25 period covered by this post. That doesn’t include the many thousands more that I took that were blurry, too bright/dark, or just not as good as the versions I decided to spend time working up and storing.

In terms of the species I’ve photographed in the plot, I’ve creeping very close to the 300 mark. I might already be there, but I still need to find some help separating species from each other among the flies, leafhoppers, and other groups. Being conservative with those identifications, I think I’m at about 288 species right now. Comparing that to the 113 I photographed in 2018, I feel pretty good, though there are a few near misses I’ll think about for a long time.

Ok, stay tuned for part 2 of this post coming soon! Get out there and explore a little bit of prairie (or whatever bit of nature you can) near you!

Grassland Restoration Network 2024 – Nachusa Grasslands

It’s always a pleasure to visit The Nature Conservancy’s Nachusa Grasslands in northern Illinois. If nothing else, it’s gratifying to see thousands of acres of restored prairie in a region where very little prairie exists otherwise. Planted prairie surrounds and connects small remnant prairies, wetlands, and savannas. The Conservancy started with little, precious ecosystem fragments and have built a prairie landscape that supports communities of plants and animals and gives them a decent chance of surviving into the future.

Plus, the place is gorgeous.

Most of the remnant prairie at Nachusa is on dry hilltops. They were surrounded by cropland, pasture, or trees, but are now embedded within a matrix of diverse prairie.

Nachusa Grasslands hosted this year’s Grassland Restoration Network. It’s a perfect place for a workshop made up of field tours and frank discussions about the challenges and successes of prairie restoration. Nachusa has a strong team of staff and incredible volunteers, and together they’ve built a program and site that is the envy of most of us in the grassland restoration world. Bill and Susan Kleiman, who live right on site, have been guiding that program since the early 1990’s.

During this year’s workshop, we spent a day and a half exploring (and marveling at) different parts of Nachusa Grasslands. We talked about their strategies for seed harvest, cleaning, and planting, invasive plant control, brush management, and the research and monitoring efforts that help them gauge success. We also went on a long evening tour in search of their bison herd.

Oh yeah, did I mention they also have bison? Apparently, people get a kick out of seeing those. We did too, though it was getting pretty dark by the time we finally came across them.

Each of the workshop tours was led by staff or volunteers who shared their experience with the 100 or so people in attendance (we had five sets of tours during each session, so group size was nice and small). What makes the network so fun, though, was that the field tours often turned into discussions among both experienced and relatively new ecologists and land stewards. Conversations were lively and fruitful, with people asking questions and sharing their own experiences.

Long-time volunteer Bernie Buchholz (center, facing away) talks to a group at an 80 acre unit he has been restoring and managing for many years.

Some of the keys to success at Nachusa Grasslands are as follows:

  • Use lots of seed (50 lbs or so of bulk, uncleaned seed per acre), including forbs, sedges, and bunchgrasses (prairie dropseed, little bluestem, needle grasses, June grass, etc.). Use very little or no seed for Indiangrass, big bluestem, or switchgrass.
  • Burn woodlands/savannas frequently, combined with mechanical shredding/clearing of larger trees.
  • Be persistent and strategic with invasive plant control. Map plants/populations and hit them repeatedly with spot spraying, mechanical removal, or whatever the best method is.
  • Make sure invasive plants and their seed bank are cleaned up before spending the time and money on a diverse planting.
  • Empower volunteers to take ownership of the site, including giving them parcels to manage/restore, and provide them support from staff and a community of other volunteers.
  • The buildings, equipment, trainings, and strategies are all incredibly organized. It was almost intimidating to see, but very impressive.

If you’re interested in the in-depth content of our discussions last week, head over to grasslandrestorationnetwork.org. Bill Kleiman, Juli Mason, and Mike Saxton moderate the site, which includes helpful blogs by them, as well as lots of guest posts by others in the field. I’m guessing there will be a summary of this year’s workshop coming soon, but you also can search for and read about lots of topics they’ve already covered. It’s a terrific, practical, easy-to-read resource.

For the rest of this post, I’m mostly going to show you photos from Nachusa Grasslands, with a little commentary. If you live or are traveling nearby, please don’t miss the opportunity to stop by and explore the site for yourselves.

Here’s Bill Kleiman (standing with the white shirt) talking about invasive plant control.
This savanna is on a good trajectory. Frequent fire has greatly reduced the abundance and density of honeysuckle and native plants are thriving in the dappled sunlight beneath the oaks, hickories, and other trees.
Prairie bushclover (Lespedeza leptostachya) is a federally listed rare plant that grows in dry upland prairie habitat. Scientists think it might thrive best with grazing, so Nachusa staff and researchers are closely watching the effects of the bison.
Much of what is now prairie at Nachusa started out as dense, brushy woodland. Converting the woodland to prairie/savanna takes time, fire, seeds, and lots of invasive species management.

It’s fun to see bison in tallgrass prairie. Or what we could see of them in that tall vegetation.
It’s also fun to see bison and bur oaks together.
