Restoring Cottonwoods to the Missouri River (Part 2)

Back in February I wrote a short post about our cottonwood tree planting efforts on the Missouri River.  Here’s a more detailed description of that project, including some early (and interesting) results.

Tyler Janke, our Missouri River restoration ecologist, holds a young cottonwood seedling from our demonstration project’s first season.

The project started as some informal discussions with Scott Josiah, the state forester for the Nebraska Forest Service.   I mentioned to Scott my concerns that most of our cottonwood woodlands on Nebraska’s big rivers consist primarily of mature trees, and that we aren’t seeing many new cottonwood stands becoming established.  As existing cottonwood trees die of old age, they’ll be replaced by the trees that are now filling the understory of the woodlands, including species such as ash, mulberry, hackberry, and eastern redcedar.  Those are all fine trees, but provide a very different kind of habitat than a cottonwood woodland.  Scott was interested in the same issue and, a few months later, approached me with an opportunity to join them on a grant application to fund a collaborative project.

We successfully obtained a grant from the U.S. Forest Service for a three year demonstration project, and the National Arbor Day Foundation jumped in with additional funding and support.  Tyler Janke, our restoration ecologist along the Missouri River is spearheading the project, and will be restoring approximately 300 acres of cottonwood woodland over the next three years.  Along the way, we’ll be trying and comparing a number of techniques to figure out what works best, including:

Photo of the Week – August 3, 2012

Still on the Niobrara Valley Preserve theme today, but not really strongly fire-related this time.

Leaf cutter bee (Megachile sp.) on plains sunflower (Helianthus petiolarus). The Nature Conservancy’s Niobrara Valley Preserve, Nebraska.  Click on the photo for a sharper look at it.

No, this isn’t some voracious predator waiting to ambush some hapless pollinator insect…it IS a pollinator insect.  More specifically, it’s a female leaf cutter bee.  I found her hanging out on an annual sunflower blossum in the early morning.  I’m not sure if she was warming up or resting or both?

Thanks to Mike Arduser for identifying the bee.  He guessed that it’s probably Megachile fortis – a specialist pollinator on sunflowers.
