About this file

This is an exhibit providing technical specifications and guidance for scalping and scalping with microsites in forest management operations, using a 30 x 30 inch scalp as the example standard.

The document outlines two distinct scalping methods. For scalping without microsites, the scalp shall be square with dimensions specified on planting data sheets, with the example showing a 30-inch scalp where scalps on one side are 30 or 31 inches apart and maintain an above ground friction clearance. For scalping with microsites, an object such as a log, stump, rock, or similar material is used and counts toward the scalp size up to a maximum of half the scalp. In the provided example, the tree is positioned 16 inches from the microsite (a 6-inch log), with 16 inches cleared in all directions from the tree except where the microsite object is located. All material must be cleared from the site 15 inches from the tree except for the area covered by the rock used as a microsite. The document includes side view and top view diagrams illustrating both scalping methods to clarify the spatial relationships and clearance requirements.
