 Why it’s called BIG bluestem: the pole is six feet tall

Four grasses form the foundation of the tallgrass prairie biome in the US: Big Bluestem, Switchgrass, Indiangrass, and Eastern Gama.  Before this land was broken to the plow, fingers of tallgrass prairie existed here in the wetter lower spots, with midgrass (Little Bluestem, Sideoats Grama, Vine Mesquite, etc)  prairie on dryer slopes and shortgrass on the rockiest areas.  This is not quite the southernmost bit of tallgrass country, but it’s getting there.  Read the rest of this entry »

Carbon sequestration is the trapping of atmospheric carbon (carbon dioxide) into some form where it can stay for decades.    Carbon sequestration occurs naturally by the actions of plants, especially long-lived vegetation, and in certain soils, where it’s deposited as slow-decaying organic matter.   Plants use sunlight to convert atmospheric carbon dioxide into the chemical that make up plant material–simple sugars, to start with, then starches and more complex chemicals when added to other nutrients.

Why is this of interest in wildlife management or prairie restoration?    The obvious reason is climate change caused by increasing carbon dioxide levels.    Carbon sequestration by changes in management of both public and private lands is one way to get carbon dioxide out of the atmosphere  and into plant materials.    Many of the things a land manager might do to promote wildlife or restore an original ecosystem (forest or grassland)  will have multiple benefits…including carbon sequestration.

A few pictures from a week ago,  May 30, and also from yesterday, June 5, as what’s blooming and in what abundance changes rapidly–especially in the hot, dry weather we’re having.  (We did get 3/10 of an inch of rain.   It barely wet the ground.)

The basketflower, Centaurea americana, looks much like a thistle at first…but the stem and leaves are not prickly at all.    It’s a favorite of Black Swallowtail butterflies (and Giant Swallowtails, if there’s enough moisture for the flowers to last into summer) and many smaller butterflies.  And also other insects.

We have no permanent natural water on the place.   But when it does rain, we have a variety of temporary water sources, from the actual creek to the various overflow channels (some of concern because of erosion; others now pretty much “tamed.”)

Some grasses should be planted just for the way they look with sunlight slanting through them in the fall.

This is one.  It’s one of the Muhlys, but I don’t know which.

An introduction to some more of our “big” grasses, now flowering beautifully after the rain.   Two are climax tallgrasses, and one is (in my opinion) one of the most beautiful grasses in the country and deserves to be used more as a landscape accent.

Meet Lindheimer Muhly (Muhlenbergia Lindheimeri).  All the Muhlys are pretty grasses; some are more striking than others, but Lindheimer Muhly is the queen of the lot:

Altogether, we’ve had 10 inches of rain since the big rain started.  Though it’s too late for some things, others have recovered well.

The yellow flowers are two-leaf senna, and the pink is the rose-oxalis that usually blooms in the early spring.

Since habitat management is part of wildlife management, restoration of degraded or poor habitat is part of our job as wildlife managers.   The basic concepts were laid down years ago…but the devil’s in the details, as usual.   The July 31, 2009 Science had an entire section on restoration ecology, with examples drawn from around the world showing the benefits, costs, and difficulties in this field.  Especially with the advent of global warming.
