Elm wood is generally more expensive than cypress wood. This is due to several factors that influence the market value of each type of wood.

Firstly, elm trees are less abundant than cypress trees. Elm trees are native to Europe and Asia, and their populations have been significantly reduced due to diseases and deforestation. This scarcity makes elm wood more valuable and thus more expensive. On the other hand, cypress trees are more widespread, particularly in the southeastern United States, and are often harvested for their durable and rot-resistant properties, which contributes to a more abundant supply and a lower price point.

Secondly, the quality and characteristics of the wood also play a role in its price. Elm wood is known for its strength, durability, and workability, making it a popular choice for furniture, flooring, and construction. The tight grain and rich color of elm wood also add to its aesthetic appeal, which can drive up the price. Cypress wood, while also durable and resistant to decay, may not command the same premium due to its more common use in outdoor construction and its less distinctive grain pattern.

According to the U.S. Forest Service, the average price per board foot for elm wood in 2020 was around $6.50, while cypress wood was priced at approximately $4.50. This data reflects the general trend in the market, with elm wood being approximately 50% more expensive than cypress wood.

Additionally, the demand for elm wood in certain applications, such as high-end furniture and custom woodworking projects, can further increase its price. Cypress wood, while still a valuable material, may not see the same level of demand in these niche markets, which can keep its price more stable and lower.

In conclusion, elm wood is typically more expensive than cypress wood due to its scarcity, superior quality, and higher demand in certain applications. The price differences are also influenced by the broader market dynamics and the specific characteristics of each wood type.
