Lowland Oaks

Oaks were once a major component of Louisiana landscapes. From the highest hills to just one step above cypress brakes, oaks were found in a variety of habitats. Today we'll consider those that grow in lowlands, such as are found in the parishes east of Monroe to the Mississippi River.

Oaks can be divided into two major groups consisting of red oaks and white oaks.

Vicksburg/Loess

The Civil War citadel of Vicksburg fell on July 4, 1863. On that day, Confedearte regiments marched out one at a time and stacked their arms. Of that occasion, General Grant's telegraph operator, Samuel Beckwith wrote, "The trampling of myriads of feet had stirred up a fine, yellow clay dust that coated our garments and filled our eyes and ears and nostrils until it was almost unberable." Like the union soldiers, this dust had origins far to the north of the Vicksburg hills.

Crow Concerns

Crows are very intelligent, have fascinating personalities, and when I watch them it's hard for me not to personify their behavior -- as in this case.

Old one-eyed crow danced around the fox lying on the roadside. He knew the miracle was coming. Still warm into death, the fox was about to give up his soul.

Wilderness Store

Less than three months after Union Parish was carved from Ouachita as a new political entity, William McKay died there intestate leaving a grieving widow and two-year old daughter.  In 1839, Union Parish was essentially wilderness and sparsely populated, the surge of immigration by settlers from eastern states just over the horizon.  McKay owned a store on the Ouachita River, either at what would later be called Alabama Landing or farther south at Ouachita City, or maybe even at the mouth of Bayou de l'Outre.

Biologists often just call them herps, an abbreviated version of the term herpetofauna meaning the reptiles and amphibians of a specific region.  The herpetofauna of Louisiana is diverse because of our mild climate that is conducive to the well-being of cold-blooded animals and because of our great variety of habitat types, from upland forests to brackish marshes.

Weather and Wildlife

Spells of harsh winter weather occasionally disrupt the daily lives of many people in Louisiana.  Technological advancements in the last 100 years, however, minimize the impacts to a short period of inconvenience for most.  Consider the differences now and during the Civil War era as described by a Confederate soldier.

Wildlife Values

Most Bayou Diversity programs involve wildlife in some form or fashion.  But who places value on wildlife and just how much is wildlife worth these days?  A recent report issued by the U.S. Fish and Wildlife Service is enlightening.

Bobcats

I saw a ghost a while back.  He appeared out of thin air, transformed a peaceful, bucolic scene into murderous chaos, and vanished in seconds.  I loved it.  It was one of the never-to-be-forgotten highlights of my experiences in the natural world.

Wise Ones

We are losing the old wise ones.  Some of our most erudite naturalists never heard a professor's lecture or studied in a biology lab that reeked of formalin and moth balls.  Still, they know the eddies where giant flathead catfish prowl and ridge-top trails of foraging coyotes.

Historians agree that the American president with the greatest conservation legacy was Theodore Roosevelt.  Among his many accomplishments in that arena was the protection of millions of acres that became units of the National Forest and National Park systems.  Additionally, he protected another group of lands and waters specifically for their wildlife values.  These became components of the National Wildlife Refuge System.
