<human>:  How can I tell which type of wood is the most durable for an outdoor deck?
<bot>: The most durable type of wood for an outdoor deck would depend on the specific environmental conditions and how much maintenance you are willing to do. In general, hardwoods such as Ipe and Tigerwood are known for their durability and resistance to weathering, making them a great choice for outdoor decks. Pressure-treated pine is also popular, as it is treated to resist decay and insect damage. Cedar and redwood are attractive and naturally resistant to wood rot and weathering. Each of these woods have their own pros and cons and you should research before making a decision.
