The Ancient Forests
Long before the first European explorers reached Louisiana, vast forests of bald cypress covered the swamps, bayous, and river bottomlands of the Gulf Coast. These were ancient forests, with individual trees reaching ages of 1,000 years or more and diameters of six to ten feet at the base. The bald cypress, Taxodium distichum, is one of the few deciduous conifers, shedding its needles each fall and re-leafing in spring. Its buttressed trunk, flared base, and distinctive knees rising from the water around it make it one of the most recognizable trees in North America.
The relationship between cypress and water is central to understanding both the tree and the lumber it produces. Bald cypress thrives in standing water and saturated soils where few other tree species can survive. This aquatic adaptation produces wood with extraordinary resistance to moisture, decay, and insect damage. The heartwood of old-growth cypress contains natural preservative oils, collectively known as cypressene, that make it one of the most durable softwoods in the world. These properties made cypress the ideal building material for a region defined by water, humidity, and the biological challenges of the subtropics.
Early Colonial Use
When the French established their first settlements in Louisiana in the early 18th century, cypress was immediately recognized as the region's most important building material. The wood was abundant, accessible by water, and possessed qualities perfectly suited to the challenges of building in a swampy, subtropical environment. Early colonial builders used cypress for virtually every component of their structures: sills, posts, beams, rafters, flooring, siding, shingles, doors, and shutters.
The construction technique known as colombage, or French colonial timber framing, relied heavily on cypress posts and beams. The oldest surviving structures in the Mississippi Valley, some dating to the 1720s and 1730s, are built with cypress that remains sound after nearly three centuries. These structures are living proof of the extraordinary durability of old-growth cypress heartwood and the skill of the colonial builders who worked with it.
Spanish colonial builders who administered Louisiana from 1763 to 1800 continued and expanded the use of cypress, adapting their own building traditions to incorporate this remarkable local material. The architectural legacy of both French and Spanish periods is visible throughout the French Quarter and other historic areas of New Orleans, where cypress structural members, millwork, and finishes survive in buildings that have weathered centuries of storms, floods, and the relentless humidity of the Gulf Coast.
The Industrial Logging Era
The 19th century saw the beginning of industrial-scale cypress logging in Louisiana. As the state's population grew and national demand for durable construction lumber increased, logging operations pushed into the swamps to harvest the seemingly inexhaustible supply of ancient cypress. The development of the pull-boat system, which used steam-powered winches and cables to drag logs from deep within the swamp to waterways for transport, made previously inaccessible stands of cypress economically harvestable.
By the late 1800s, Louisiana was the leading producer of cypress lumber in the United States. Dozens of sawmills operated across the state, processing logs that were often four to six feet in diameter and producing lumber of a quality that is difficult for modern observers to comprehend. Wide boards, clear of knots, tight-grained, and rich with the natural oils that give cypress its legendary durability, flowed from Louisiana mills to construction projects across the nation. Cypress was marketed as the wood eternal, a name justified by its remarkable resistance to the elements.
The peak of cypress logging in Louisiana occurred between 1890 and 1925. During this period, enormous volumes of old-growth cypress were harvested and converted to lumber. The scale of the operation was staggering, with some estimates suggesting that over 16 billion board feet of cypress lumber were produced in Louisiana during this era. The industry employed thousands of workers and supported entire communities built around the mills and logging camps.
The Decline and Its Consequences
By the 1930s, the old-growth cypress forests of Louisiana were essentially exhausted. The trees that had taken 500 to 1,000 years to grow had been harvested in roughly 40 years of intensive logging. Some swamps were logged so completely that the forest ecosystem was fundamentally altered, with changes in hydrology, soil structure, and species composition that persist to this day. The cypress logging industry collapsed as the raw material disappeared, and the mill towns that had depended on it were abandoned or shrank dramatically.
Second-growth cypress began to regenerate in many of the logged swamps, but these young trees produce lumber that is fundamentally different from the old-growth material. Second-growth cypress grows faster, producing wider growth rings, less heartwood, and lower concentrations of the natural preservative oils that make old-growth cypress so durable. While second-growth cypress is still a useful construction material, it does not match the performance of old-growth timber, particularly for exterior applications where decay resistance is critical.
Reclaiming the Legacy
Today, the most reliable source of old-growth cypress is the reclaimed lumber market. The enormous quantity of cypress used in Louisiana construction over three centuries means that buildings across the state contain substantial reserves of old-growth cypress lumber. As these buildings are renovated, deconstructed, or, regrettably, lost to storms and neglect, the cypress within them becomes available for salvage and reuse.
At Lumber New Orleans, reclaimed cypress is one of our signature products. We source old-growth cypress from historic buildings, industrial structures, and other sources throughout the Gulf Coast region. Each piece carries within it a connection to the ancient forests that once defined the Louisiana landscape and to the generations of builders who recognized and utilized the extraordinary properties of this remarkable wood. When a customer uses our reclaimed cypress in a new project, they are continuing a tradition of cypress construction that stretches back to the founding of Louisiana itself.
Another fascinating source of old-growth cypress is the recovery of sinker logs from river bottoms and lake beds. When the original forests were logged, countless logs sank during transport and have been preserved for over a century in the oxygen-depleted waters and mud of Louisiana waterways. These sinker cypress logs, when recovered and milled, produce lumber of extraordinary quality, with the tight grain and rich color of old-growth timber and a unique coloration from mineral absorption during their time underwater. Sinker cypress has become a premium product in the reclaimed lumber market, prized by woodworkers and builders who appreciate its rarity and beauty.
