==Production and types of barkdust== Barkdust is commonly produced from several tree species. The Douglas fir and the Western hemlock are the most common sources of barkdust, with cedar bark also being used. Barkdust may be a byproduct of lumber production, of yard debris recycling processes, or it may be produced in its own right. Barkdust is typically categorized by the source plant, as well as by the coarseness of the resulting material. Fine barkdusts are used as mulch, with coarser forms being used for weed control, as a playground surface, or for decorative purposes.
