In 1974 the Texas Big Thicket National Preserve of 84,550 acres (342.2 km 2) was created by Congress. The preserve actually consists of 12 distinct units of forest land that are protected from lumbering activities. [13] These and other preservation efforts have helped to stabilize parts of the Texas woodlands. [35]
Wood easily degrades without sufficient preservation. Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood ...

[1] Creosote and its extenders were used in wood preservation processes at a nearby rail yard and have been identified as carcinogens that are hazardous to human health.
Timber physics, timber testing, and the pulp, paper and wood preservation labs moved into the first floor. Wood chemistry and wood distillation labs were on the second floor. [2] The whole initially employed forty-five researchers. [4] For a few years the lab at Madison remained the world's only institution dedicated to research on wood and its ...

Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged w
Wood decay describes wood in all stages of fungal attack, from the initial invasion of hyphae into the cell walls to the complete destruction of the wood. [10] Wood-inhabiting fungi are most common on timber piles above the water surface since the lack of oxygen below water inhibits fungal growth.
