Which method does NOT contribute to wood protection?

The method that does not contribute to wood protection is exposing wood to direct sunlight constantly. While wood exposure to sunlight can dry it out and cause weathering, prolonged exposure can actually lead to increased degradation. Ultraviolet (UV) radiation from sunlight can break down the chemical structure of wood fibers, leading to issues such as fading, cracking, and warping.

In contrast, controlling wood moisture content is essential for preventing issues like mold growth and decay, which are caused by excessive moisture. Using wood that is naturally resistant to pests offers inherent protection, as certain wood species contain compounds that deter insects and fungi. Treating wood with chemical preservatives effectively creates a barrier against biological threats, further enhancing its longevity. Thus, constant exposure to direct sunlight lacks protective benefits and can instead be detrimental to the wood's structural integrity.
