What type of wood has the best natural resistance to decay and to outdoor elements?

Redwood is known for having exceptional natural resistance to decay and the elements, making it an ideal choice for outdoor applications. This durability is primarily due to its high levels of tannins and other compounds that inhibit the growth of fungi and insects, which are common causes of wood decay. Redwood can withstand various weather conditions, including rain, sun, and humidity, without deteriorating as quickly as other types of wood.

While cedar also exhibits good resistance to decay, redwood tends to outperform it in terms of longevity and stability in outdoor environments. Pine, although commonly used in construction, does not possess the same level of natural resistance and is more susceptible to rot unless treated. Maple, while a strong and dense wood, is not typically used for outdoor applications due to its lower resistance to the elements. Thus, redwood stands out as the best option for enduring the challenges of outdoor exposure.
