Wood decay is the process by which wood is broken down and degraded by various microorganisms, fungi, and insects. This can lead to structural damage in wooden structures and furniture. Understanding the causes and mechanisms of wood decay is important for conservation efforts, as well as for developing techniques to prevent or mitigate decay. Researchers in this area study the biology of wood-degrading organisms, the chemical processes involved in decay, and strategies for preserving wood. They may also investigate the environmental factors that influence the rate and extent of decay, such as moisture, temperature, and oxygen levels. Overall, research in wood decay aims to improve our knowledge of how wood deteriorates and how to protect wooden materials for long-term use.
