Present: Current Ecosystem Conditions

LANDFIRE’s Existing Vegetation Type, Cover and Height datasets describe vegetation conditions.

• Existing Vegetation Type (EVT) - represents the current distribution of the terrestrial ecological systems classification, developed by NatureServe for the western hemisphere, through 2020
• Existing Vegetation Cover (EVC) - represents the vertically projected percent cover of the live canopy layer for a 30-m cell
• Existing Vegetation Height (EVH) - represents the average height of the dominant vegetation for a 30-m cell

Summary

• More than 60% of the landscape is dominated by sagebrush EVT.

Existing Vegetation Cover

The Existing Vegetation Cover (EVC) map is a visual representation of EVC classifications across the subregion. The chart below the map provides a breakdown of each vegetation cover classification and their relative dominance across the subregion

From this information, we can see that the majority of this subregion is classified as “shrub,” comprising approximately 80% of the vegetation cover.

Existing Vegetation Height

The Existing Vegetation Height (EVH) map showcases EVH across the subregion. The chart below the map provides the percentage of the landscape represented by each EVH height.

From these results, we can see the majority of vegetation on the landscape is .25-.9 meters in height.
