  • When Restoring Nature Every Little Bit Helps

    I’m getting excited about this upcoming field season. For the first time in several years, we’re going to be attempting to harvest seed from as many prairie plant species as we can. Between about 1997 and 2005, we spent much of each field season hand-picking seeds from a broad diversity of species – often ending up with over 200 species by the end of the season. It was exciting and fulfilling, and we were often able to create up to a couple hundred acres of new prairie habitat each year.

    Since that time, we’ve focused less on converting cropland to high-diversity prairie (we ran out of cropland!) and more on harvesting large amounts of fewer species to overseed degraded prairies. I’m not sure we’ll be able to harvest as many as 200 species this summer – we’re pulled in many more directions now than we were in our “glory years” of seed harvesting – but making the attempt will be fun.

    During those glory years, we worked hard to build the most diverse seed mixture possible. We used to joke about how many seeds we had to get from a plant species before we could add it to that year’s harvest list.  It kind of felt like cheating when we’d only find a handful or two of seeds from a species but would add it to the list anyway.  However, we justified listing those species because of conversations with people who had much more experience than we did (especially Bill Whitney with Prairie Plains Resource Institute) who claimed that even a few seeds would usually be enough to establish a species in a new prairie. Besides, we figured if the species was appropriate to the site, tiny populations would spread out over time.

    Now that I’ve had up to 17 years to watch the establishment of plantings I personally harvested seed for, I can testify that Bill and others were right. Sometimes, just a few seeds really are enough. That knowledge is awfully good for morale when we’re on our hands and knees searching for violet or pale poppy mallow (Callirhoe alcoides) plants to harvest from. Those are just two or many examples of plants that are short, have widely scattered populations in our prairies, and are difficult to find at seed harvest time because the surrounding vegetation has grown tall enough to obscure them from sight. To make things worse, neither of those species produces many seeds per plant, so even when you find a plant, you might only get 20-50 seeds out of it.

    Knowing that those 20-50 seeds are worth finding makes crawling on hands and knees seem much less tedious.  Ok, a LITTLE less tedious. Read more...

  • Invasive Species List

    Invasive plants displace native plant species, reduce wildlife habitat and damage natural ecosystems. They threaten natural areas and parks and spread via roadways, rivers and trails. In the United States, they cost an estimated $34 billion annually in economic loss.

    Here is a good list of invasive plants to look out for. Its from Virginia which applies generally to northwest Illinois and, unfortunately, may indicate things to come.

    If you're interested, here is their invasive species management plan. Good luck Virginaia.

  • Natural Areas Have Intrinsic Value

    Much of the conservation community’s current approach to conservation planning is a commodification of nature. Lands are valued according to laundry lists of the tangible services (e.g. water quality protection, forage, carbon storage) they provide. We might not assign actual dollars to such services, but we’re certainly thinking about cash for services.

    …and sometimes that’s fine.

  • Does Plant Diversity Matter?

    2013 photos from

    How important is plant diversity in restored prairies? Are diverse prairies more resistant to drought and invasive species? How does plant diversity influence invertebrate communities?

    The plots above, from left to right, were planted to a monoculture (big bluestem), a low diversity mixture (mostly grasses and a few late season wildflowers) and a high diversity mixture (100 plant species).  TNC is investigating the functional differences between these kinds of plant communities. The plots are 3/4 acre and represent varying levels of plant diversity. Researchers from the University of Nebraska, Kansas State University, the University of Illinois, and Simpson College have been involved in data collection efforts so far.

    Stay tuned.

    Join the Grassland Restoration Network near Hawley in northwest Minnesota for presentations and discussion on restorations at scale and use of high diversity local ecotype seed. Field trips will include tours through several stages of grassland reconstruction at Bluestem Prairie and Glacial Ridge National Wildlife Refuge.

  • European bison lived in grasslands, not forests

    Paleontologists examined the oldest known bones of bison from Europe. Their research revealed that European Bison were “mixed eaters” who preferred open landscapes to a life in the forest. These findings have a direct impact on the current conservation concept for these animals, which are threatened with extinction.

    Until now it was assumed that the European Bison -- in contrast to its steppe-dwelling relatives in North America -- primarily thrive in forests. Based on the examination of isotopes from the age-old bones of the large mammals, Bocherens and his colleague, Prof. Dr. Rafal Kowalczyk of the "Mammal Research Institute" in Białowieża, Poland were able to verify that European Bison were "mixed eaters." "The ratio of carbon and nitrogen isotopes in the bones indicates that the bison's diet in the early Holocene included leaves as well as grasses and lichens.Until now it was assumed that the European Bison -- in contrast to its steppe-dwelling relatives in North America -- primarily thrive in forests.

  • EARTH: A New Wild

    Did you watch the second episode of "Earth: A New Wild" on Public Television? If you missed it, you can see "Episode 2: Plains" here. I watched it, and while I was glad for the attention paid to grasslands, I also had some concerns about the content.

    It is very difficult for the public to know what information is based on good science and what is not. I felt this episode led people to believe that the strategies it advocated were better supported by science than they really are. Read more...

  • Looking Past the Ugly Spots

    Hoary vervain (purple) helps trace the outline of this ugly patch, which is also filled with species such as sweet clover, tall dropseed, and Kentucky bluegrass.

    Much of our restored prairies are full of color and beauty throughout the growing season.  It’s a pleasure to walk through them. However, not every square foot is lush and beautiful. In fact, some areas are pretty ugly, dominated by weeds or bare ground. Luckily, our objective is not to create pretty flower gardens. Read more...

  • It’s Not Always Pretty

    Farmland Restoration

    My project’s big goal is to restore the farmland that APR owns to native prairie so that it can function in the ecosystem again. The process will reintroduce a wide range of vegetation to the sites, change the soil over from furrows, and create important food sources for wildlife and pollinators. Along the way, we have mini goals that we need to reach, from getting crops established and smoothing out the soils to finally establishing the diverse mixes of grasses, shrubs and wildflowers that make a mixed-grass prairie work.
