Timber REITs own and/or manage nearly 30 million acres of US timberlands, more land than the smallest five states in the US combined.

Weyerhaeuser and PotlatchDeltic each have significant business operations along the lumber supply chain - not only timberland ownership but also in lumber production and manufacturing - transforming the raw timber into usable construction materials. Rayonier and CatchMark, on the other hand, are more "pure-play" timberland owners.
