Lumber is a resource that takes an incredibly long time to deal with supply chain disruptions, but for which large scale supply disruptions are difficult. First you need to plant trees years in advance before you harvest them, then green lumber needs to age for an extended period of time before it can be used. If you for some reason have to stop felling trees for a few months, a few months later you're going to have a shortage; and while you can cut down those trees later, if people start panic buying there are only so many trees ready to be felled. Luckily forests are spread out over many areas and logging does not depend on any suppliers that represent a single point of failure, so the odds of every logging operation getting disrupted at the same time is astronomically low - unless there's a global pandemic or something.
