Quick note – don’t forget our public field day at the Platte River Prairies will be Saturday July 8. Detailed schedule coming soon, but there will be opportunities to learn about plants, birds, mice, invertebrates, prairie restoration and management, and more! The event runs from 7:15am to 2pm and you can come and go as you like. Also, it’s free!

Wow, June has been busy. Attending the North American Prairie Conference next week isn’t going to slow things down, but I’m looking forward to it. Maybe I’ll see you there.

Don’t get me wrong, it’s been a great month, including a productive trip to the Niobrara Valley Preserve last week. I’m sharing just a sliver of the photos from that trip here today. I’d tell you more about it, but see the previous paragraph.

Prickly pear cactus (Opuntia humifus).
Weevil in cactus flower. There was an even cooler weevil, but I didn’t get a shot of it. This, then, was the lesser of two weevils. Good night now!
Long-billed curlew. Despite appearances, it didn’t tip over forward even once.

Bison. (You probably knew that)
Scarlet gaura (Gaura coccinea)
A profusion of flowers in a pasture where drought, fire, and grazing all coincided last year. A wet winter and good rains so far this year triggered the explosion.

Photos of the Week – June 9, 2023

Last weekend, I was honored to be a speaker and hike leader at the annual Loess Hills Prairie Seminar near Onawa, Iowa. It was inspiring and energizing to be around 100 or so other people who were fascinated by, and trying to learn more about prairies. If you have the opportunity to attend this event in the future, I highly recommend it.

Sunday morning, I woke before sunrise and climbed a prairie ridge at the Loess Hills Wildlife Management Area. I’d scouted it the previous afternoon and knew the sun would light it up beautifully if the weather forecast held true. It did and it did.

The prairie had quite a few blooming yucca plants, as did lots of other hills in the neighborhood. There were other flowers, too, but it was really hard to ignore the visual power of the yucca plants. I didn’t try very hard to ignore them. As the sun first peeked above the horizon, I grabbed my long telephoto and played around with various compositions that included the sun behind yucca flowers. Following that, I tried other lenses and perspectives until the sun finally rose high enough that it lost most of its color.

I switched lenses and focused on the individual flowers for a while, appreciating their unique architecture. However, I kept seeing potential wide-angle shots too, so I rotated through lenses quite a bit during the next hour or so.

During my scouting trip the previous day, I’d been looking for the tiny white yucca moths that are the sole pollinator of yucca flowers. I found a few and even photographed one of them – using my macro lens to peek through the opening in a partially-closed flower. During my Sunday morning photography hike, though, I couldn’t find any moths that would pose for me, which was a shame since the light was fantastic.

By now, you’re probably wondering to yourself, “Surely, he photographed some crab spiders, right?”

Yes, of course I did.

In addition to crab spiders, other spiders were around, including a cute little orb web spider that didn’t seem agitated by my slow, careful approach. In fact, as I positioned my tripod close to the web, little flies swarming around my head kept hitting the silken threads, giving the spider something to distract her and me more action to photograph.

Yucca flowers weren’t the only ones I saw, of course. Bluets were still blooming, though many were done for the spring. Yellow flax flowers dotted the hills, too, and a few green milkweeds were hiding here and there. Unfortunately, I also saw a couple patches of leafy spurge and even more patches of crown vetch. Both are nasty invasive species that are challenging to deal with and are more abundant than anyone would like to see in the Iowa Loess Hills and other prairie landscapes in Iowa and Nebraska.

If you’ve not spent time in the Iowa Loess Hills, it’s a fabulous landscape and worth a trip. The steep hills aren’t for the faint of heart, but the climbs are worthwhile when you reach the ridge tops and get to appreciate the views. Though the prairie is in the tallgrass prairie ecoregion, the steep slopes and associated dry soils host a lot of plant species that I recognize from the mixed-grass prairie in central Nebraska. We also share the woody encroachment threat faced in both regions…

All-in-all, the hills, flowers, and wonderful people made a pretty sweet combination. It’s easy to see why so many people were excited to attend the Seminar and celebrate the Iowa Loess Hills.
