F-6 Figure 8. Artificial cavity.pdf

The image is F-6 Figure 8, a technical diagram depicting an artificial cavity design for a tree. The illustration shows a detailed schematic of a tree with branches and roots, with a precise cutout or cavity created in the trunk. Accompanying the tree drawing are two detailed view diagrams - a side view and a front view - which provide specific measurements:

Side view specifications include dimensions of 7 inches wide and 8 inches tall, while the front view shows a 1/4 diameter hole and specific spatial measurements. The entire tree is drawn to a height of 35 feet, with the artificial cavity positioned approximately midway up the trunk. The technical drawing appears to be part of a wildlife habitat or forestry management document, likely related to the Hebo RD Wildlife Tree and Downed Wood Creation federal contract opportunity for the Department of Agriculture Forest Service.
