Raw Land

No doubt landscapes tug on our psyche. Whether a snow-capped Colorado mountain or a shimmering gulf coast beach, our brains react to certain topographies in peculiar ways. We are all different in our feelings toward distinctive terrains – some attract, some are foreboding. For me there is a landscape in northeastern Louisiana that never fails to stir something below the surface of my consciousness.

 

Pied-billed Grebe

The degree-toting ornithologists call her pied-billed grebe but in Louisiana she answers to “di-dipper,” or “hell-diver” on a bad day. For her the water’s surface is only an interim point in space and time. That she spends precious few moments there is an aggravation for birdwatchers and boys with BB guns, not to mention the serious predators be they finned, feathered or scaled. Departing the planner ecotone dividing atmosphere and liquid is more graceful if she chooses the denser of the two mediums. The downward dive is faster than the eye can appreciate the choreography.

 

Fences

About a hundred yards north of my house in the dense woods, the remnants of an old fence can be seen running north-south over a sandy-clay hill on the edge of D'Arbonne Swamp. The forest looks the same on both sides of the rusty wire now, but it once enclosed a ten-acre field where my father chopped cotton as  a teenager. When boll weevils, armyworms, and worn out soil forced Union Parish hill-country cotton farmers to seek work in paper mills, chemical plants, and on pipelines, the field reverted to forest through natural plant succession.

Probably the most popular kinds of fish in this area are bass, white perch or crappie, bream, and catfish. They are well known because they are fun to catch and good to eat. However, in terms of biological diversity, this group falls at the bottom rung of the aquatic ladder. In Louisiana, there are only two species of black bass, two species of bream-like sunfish. Another group, almost completely unknown even to amid fishermen, swims our rivers and creeks with dramatic diversity of form, color, and species. Collectively, they are called Darters.

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.
