Is Mastication Right for Your Site Science-based Decision Trees for Forest Managers

This decision aid explores the mechanical process of mastication, a forest management technique that grinds dense vegetation into floor mulch to reduce wildfire risks and enhance ecological health. By using a series of decision trees, the document provides land managers with a structured framework for evaluating site-specific factors such as slope steepness, soil sensitivity, and tree density to determine if machinery is a viable alternative to prescribed burning. The document emphasizes that successful outcomes depend heavily on operator expertise and the selection of specialized equipment, which can minimize soil compaction while precisely tailoring debris size. This decision aid serves as a practical manual for balancing fuel treatment objectives with environmental stewardship, highlighting how strategic mulching can protect landscapes where traditional fire use is restricted.
