Wood Chips

Can wood chips be a cultural keystone species? I guess what also defines it, is that it must have some deeper connection to the lives of the people, you can’t rush this. It might take years for this connection to be very visible, maybe our goal is then to research the potential of certain materials to understand if they could be cultural keystone species. I believe wood chips could hold the potential. Especially if you look at invasive species such as the Black Cherry Tree. If we could chip these trees and use them to harvest heat? The whole goal is to be depend on natural elements. That is what established a connection and thus holds potential for becoming a keystone species?
