Bees in a Restored Prairie Landscape – So far, So Good

Mike Arduser has (mostly) finished identifying the bees we found during our insect week in early July this year.  Though the data we collected during that week was just a first step, the early results are very positive.  It appears that our restored prairies are providing adequate habitat for most bee species, including some that have fairly specialized needs for nesting or feeding habitat.  Below is a summary of what we’ve found so far, what I think it means, and what our next steps are.

As a reminder, our restoration objective is to reconnect and enlarge existing prairies by converting nearby crop fields to high-diversity prairie plant communities.  We hope the result is a larger, more connected, and more ecologically resilient prairie landscape.  The diverse plant communities in those restorations have successfully established, and we’ve been able to measure that by tracking plant species diversity and floristic quality.  It’s been more difficult to measure whether or not those restored prairies are actually stitching the surrounding landscape back together.  Our insect week this summer was an important step in evaluating that.

Testing Assumptions – The Milkweed Seed Fiasco

A few months ago, I mentioned a technique that we use to clean milkweed seeds after harvest.  We spread the fluffy seeds out on a concrete floor and light the thin pile on fire, burning the fluff off the seeds.  It’s quick, easy, and fun.  I learned of the technique from a fellow prairie restoration ecologist many years ago, and we’ve been using it ever since.  I’ve also shared the idea with quite a few others.

Burning the fluff off of milkweed seeds. Don’t try this at home.

Those of you who have either read this blog frequently or know me personally know that I am a strong advocate for experimenting with techniques whenever possible.  In fact, I often reduce people to blank stares by blathering on about the importance of always testing restoration and other methods to be sure we’re using the most effective strategies.  Surely, then, over the last decade or so that I’ve been using and advocating the “burn the fluff off” technique, I’ve followed my own advice and checked to make sure it actually works, right?   Well…
