Abstract: An engineered wood based soil mulch product is described that is a blend of geometrically regular wood elements. The blend has at least two components that differ by at least one dimension. Element length is within the range of about 50-300 mm with a maximum width of about 30 mm. The product is preferably formed from wood veneer having a maximum thickness of about 7.5 mm. Individual elements may be formed as long strands, as rectangles, other polygons, or with curvilinear edges. Mixtures of elements having differing geometric form are acceptable and in some cases advantageous.

Abstract: An engineered log jam for controlling stream flow characteristics is formed from multiple layers of logs. A first layer intended to be placed parallel to stream flow consists of two or more generally parallel logs. In normal use these would be anchored to the stream bottom. A second layer of logs is placed on top of the first. This also consists of a plurality of spaced apart logs crossing the first layer. The second layer logs are angled with respect to each other to control and direct water flow passing over and through the structure. A third layer of spaced apart logs crosses the second layer logs and further acts to direct water flow. Additional layers may be used as might be dictated by the use environment. The logs are permanently joined to each other at the points of crossing.

Abstract: An engineered wood structure is shown that can be placed in an aquatic or other environment. It is particularly useful in environmental enhancement efforts as a resting place for various avian and aquatic species. The structure is preferably made from small logs. A number of logs are placed side-by-side to form a deck surface. A single log is spaced apart from and generally centered below the deck logs. A pair of spaced apart struts depend from the lower surface of each deck log and are connected into the keel log to form a unitary structure.
