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.

Succession classes for most dominant BpSs

  • The Northern Rocky Mountain Dry-Mesic Montane Mixed Conifer Forest - Ponderosa Pine-Douglas-fir shows a substantial ‘over-representation’ of succession class D and a corresponding under-representation of class C presumably due to altered disturbance regimes.
  • The Northern Rocky Mountain Subalpine Woodland and Parkland shows a substantial under-representation of class B, and a over-representation of class D.
