36 Hours on the Prairie: Wildflowers

[August 17 & 18, 2018: I made a quick dash to the prairies of Western Minnesota in mid August. Much of my time is spent in the boreal forest and bogs of northeast Minnesota, and I was starting to get a bit claustrophobic. So off to the wide open prairies! I started at Otter Tail County’s Maplewood State Park, then on to Wilkin County (Town Hall Prairie, Western Prairie, Rothsay WMA) and continued north to the huge Felton Prairie complex in Clay County. The next day I hit Felton area again and headed north to the Glacial Ridge National Wildlife Refuge in Polk County]

Wildflowers on the tallgrass prairie peak in mid July to early August, but there were still plenty of showy plants in full bloom in mid August. It is energizing to be in an unfamiliar habitat and meeting new species, or at least species I hadn’t seen in many years. The Liatris were in full bloom on many of the dry sites. You may know Liatris as Gay Feather or Blazing-Star, but did you know that there are a bunch of different species in Minnesota? I didn’t. I even found a white variant of the normally pink-flowered forb (photos below). Monarchs and Regal Fritillaries love to nectar on Liatris.

Pink-flowered Wild Onion (Allium stellatum) was new to me, and is now one of my favorites.

I was really surprised to find Harebell (Campanula rotundifolia) growing on the dry soils of Felton Prairie (Clay County, Minnesota). I am most familiar with this delicate beauty clinging to tiny cracks in the igneous rocks on the Shore of Lake Superior! But this is a very adaptable and hardy species that can be found in many habitats.

Wild Four-o-clock (Mirabilis nyctaginea) is a native prairie species that can also be found in waste places. The “four-o-clock” in our domestic gardens was cultivated from a related European species. The name comes from the fact that this plant opens only in late afternoon. In fact the Latin “nyctaginea” means “night blooming” from the Greek.

You can bet that I will be back out on the prairies next spring and summer to see more of our tallgrass prairie’s fantastic flowers.

36 Hours on the Prairie: Glacial Ridge National Wildlife Refuge

Glacial Ridge NWR is in northwestern Minnesota and is a complex of prairie tracts that has been consolidated as a federal National Wildlife Refuge. It is a vast complex of “aspen parkland” prairie habitat; savannah like in that there are clusters of aspen trees dotting the grassland.

Glacial Ridge National Wildlife Refuge was established in 2004 and is Minnesota’s newest addition to the NWR system. It is a vast area, that will eventually encompass 37,000 acres (57 square miles)

It is described by the US Fish and Wildlife Service as “the largest tallgrass prairie and wetland restoration project in U.S. history.” [from wikipedia.com]

Hoar Frost Morning—Glacial Ridge National Wildlife Refuge-March 9-10

There were 20 cases of books waiting for me in Pembina, North Dakota. My printer is in Altona, Manitoba and they kindly brought a pallet of books just across the U.S. border so I wouldn’t have to pay duty. And since I was going all the way there, why not do some photography on the way?!

I left Wrenshall at 3:20 am so I could be in far western Minnesota by sunrise. And I made it! Since the radio in the van doesn’t work, podcasts keep me entertained. As I turned off US2 into Glacial Ridge National Wildlife Refuge, I knew it was going to be a spectacular morning. Thick coats of hoarfrost coated everything! Every twig, branch, blade of grass, strand of barbed wire held a coating of thick feathery frost.

Conditions were PERFECT for hoarfrost formation….Temperatures at sunrise were near ZERO degrees F and dead calm, and the day before had been above freezing so I imagine moisture from the melting snow provided the “raw material” for spectacular hoarfrost formation.

Here is some info from http://www.wikipedia.org:

“Hoar frost (also hoarfrost, radiation frost, or pruina) refers to white ice crystals deposited on the ground or loosely attached to exposed objects, such as wires or leaves.[4] They form on cold, clear nights when conditions are such that heat radiates out to the open air faster than it can be replaced from nearby sources, such as wind or warm objects. Under suitable circumstances, objects cool to below the frost point[5] of the surrounding air, well below the freezing point of water. Such freezing may be promoted by effects such as flood frost or frost pocket.[6] These occur when ground-level radiation loses cool air until it flows downhill and accumulates in pockets of very cold air in valleys and hollows. Hoar frost may freeze in such low-lying cold air even when the air temperature a few feet above ground is well above freezing.

The word hoar comes from an Old English adjective that means “showing signs of old age”. In this context, it refers to the frost that makes trees and bushes look like white hair.

Hoar frost may have different names depending on where it forms:

  • Air hoar is a deposit of hoar frost on objects above the surface, such as tree branches, plant stems, and wires.”

Coyote in frosty meadow. I tried squeaking and pishing to bring her closer, and it worked…kind of. She came back towards me, but only within about 200 yards.
