Hubbard Fellowship Blog – Why is Prairie Conservation Important?

A guest post – and a couple questions for you – from Eliza Perry, one of our Hubbard Fellows:

I arrived in Nebraska with romantic preconceptions of prairie, probably influenced by my mild obsession with Laura Ingalls Wilder as a child. Back then, I thought up designs for a covered wagon that would meet the cruelest of weather and environmental conditions—automatically elevating wagon-stilts, for example, to protect us from wildfires caused by lightning strikes—without sacrificing luxury. My wagon featured recliners for the driver and passenger seats, a loft outfitted with giant beanbag chairs for sleeping, and multiple TVs. We would be fully equipped to cross the endless grasslands, with extra storage space for our crates of never-rotting fresh produce and cereal. I won’t even get into the tree houses I devised at this age.

Unsurprisingly, I was taken aback by the real prairie landscape, which was fenced off, bordered by large crop fields regularly showered in pesticides, and seemed to require constant tending – at least when we arrived at the height of thistle season. This disillusionment was valuable because it gave me a skepticism that has since faded, but challenged me to actively reflect on my role in this ecosystem, why I think it is important to protect, and what “protecting” it might really mean.

Prairie landscapes are certainly striking, but much of that landscape has been drastically changed, leaving very little actual prairie in many places.

Prairie landscapes are certainly striking, but many of those landscapes have been drastically changed so that actual prairie can be hard to find.

My interest in the social and ethical facets of conservation make it especially important to me to be able to make a case to any audience for the importance, relevance, urgency, morality, etc. of conservation goals. In college, I studied plenty of abstract moral arguments on the relationship between humans and nature and what obligations we have toward nature, but now I want to hear from people about their personal perspectives on those issues.

Because I’m new to grasslands, I have a different – and certainly still developing – relationship with prairie than those who have loved and/or worked on prairie for a long time. By now, I’ve asked several people why they feel it’s important to conserve prairies, and I’ve gotten answers ranging from a spiritual obligation to “steward the land,” a utilitarian need to conserve biodiversity, to the “intellectual challenge” prairie conservation offers, to name a few. I hope that as I gather new perspectives, I will be better equipped to engage with people on the significance of the work we do here on the Platte.

I think I’m asking two questions, though the answers may be the same for some: Why do you think it is important to conserve prairie, and why are you personally working to conserve prairie?

I’d love to hear your responses.

Hubbard Fellowship Blog – A Few of Anne’s Favorite Bees

Guest Post by Anne Stine, Hubbard Fellow:

I just finished a wonderful pollinator work shop with Mike Arduser here at the Platte River Prairies.  Much of this workshop involved catching bees, using a dichotomous key to identify them to genus, and then pinning the bees on-site.  I am pretty pleased with my collection, and I’ve decided to share a few of the fascinating factoids that are buzzing (I am so, so sorry) around my head.

Agapostemon virescens is my new favorite bee.  They are eusocial, but not tyrannically so.  There is no queen, all females can reproduce; they just choose to share a nest (from “The Bee Genera of Eastern Canada”; Packer, Genaro, and Sheffield 2007).  I adore these utopian bees. They also happen to be gorgeous.  I’ve included a picture of the male below.  The female looks similar, but is all emerald without the striped abdomen.

Svastra obliqua is my second favorite bee.  Their scopa (branched, pollen carrying hairs) are so exaggerated, they look like they are wearing giant fuzzy chaps.  Big and easy to spot, they hang around annual sunflowers and could be confused (if you were squinting and using your peripheral vision) with a small bumblebee.

The Megachile family is another good group.  Instead of having scopa on their legs, they carry pollen on their abdomens.  This placement requires them to rub their bellies all over a flower when they forage.  It’s a pretty amusing mental picture.  Another reason to love the Megachile is that they can be field ID’d by ear.  After conferring with my fellow pollinator work shop participants, we decided that, if the bumblebee is a Harley (low pitched, rumbling “BZZZzz”, then the Megachile is the sportbike (they make a high pitched “eeeeee” sound when they forage).  Once you hear their whine, you won’t forget it.  Megachiles are leafcutters, and they excise circular patches from leaves to build their nests.  If you see a leaf that looks like a crazed administrator took a hole-punch to it, you should start listening for the Megachile whine.

Hymenoptera bonus: the cuckoo wasp.  She’s wearing a rhinestone suit of armor.

There is so much more I wish to share!  I foresee future posts about buzz pollination, specialists vs. generalists, combative cleptoparasites, and the potential for the hymenopteran community as an indicator of restoration success.

Hymenopterans are beautiful, sometimes adorable, with unusual life histories that make their study easy to enjoy. I am so pleased I get to spend time with these creatures during my fellowship here on the Platte River Prairies.
