As used in the exemption, other forestry products means plants of the forest and the natural properties or substances of such plants and trees. Included among these are decorative greens such as holly, ferns, roots, stems, leaves, Spanish moss, wild fruit, and brush. Christmas trees are only included where they are gathered in the wild from forests or from uncultivated land and not produced through the application of extensive agricultural or horticultural techniques. See 29 CFR 780.205 for further discussion. Gathering and preparing such forestry products as well as transporting them to the mill, processing plant, railroad, or other transportation terminal are among the described operations. Preparing such forestry products does not include operations that change the natural physical or chemical condition of the products or that amount to extracting (as distinguished from gathering) such as shelling nuts, or that mash berries to obtain juices.
