Comparisons

Comparing Past vs. Present Conditions

Using LANDFIRE’s BpS products, we explore two different ways to visualize past vs. current vegetation patterns.

• First we present changes in broad ecosystem types using an interactive comparison diagram.

• Second we compare amounts of succession classes (past and present) for the most prevalent ecosystems.

Comparing Broad Vegetation Trends

Summary

• LANDFIRE mapped a fair amount of change in the “Past Grassland” category. Roughly 50% of this type has been mapped as non-grassland types today.
• There appears to be an increase in the shrub category.
• Note: number presented when hovering equals acres.

Succession classes for most dominant BpSs

• Succession classes have changed the most in the
  Northern Rocky Mountain Lower Montane-Foothill-Valley Grassland BpS, with a substantial under representation of succession class B currently.
• Some BpSs appear to be missing succession classes on the landscape today, such as the
  Northwestern Great Plains Highland White Spruce Woodland missing succession class C (in addtion to a sever over representation of class E).
