Description: <div style="text-align:Left; font-size:12pt;"><p><span>Ladder fuels were derived from the 2019 QL1 countywide point cloud. A ladder fuel proxy was developed to provide an indication of the density of vegetation of in the 1-4 meter above ground stratum. This continuous value (0-1 range) was classified into four classes for each forest lifeform class. As a result, the countywide count of very high, high, medium and low ladder fuel polygons within each forest lifeform class (e.g., evergreen forest) is roughly the same.</span></p><p><span style="font-size:15px;">See Chapter 6 of the </span><a href="https://www.onetam.org/sites/default/files/pdfs/marin_regional_forest_health_strategy_2023.pdf" style="font-size:15px;" target="_blank">Marin Regional Forest Health Strategy</a><span style="font-size:15px;"> (Page 276 - Classified Ladder Fuels) for more information.</span><span><br /></span></p></div>
