New vegetation departure fields to parse riparian loss and invasive encroachment #17

Closed mhallerud closed 4 years ago

mhallerud commented 4 years ago

@wally-mac, Jenna Walsh (from the USFS PIBO team) and I have been investigating RCAT outputs for the PIBO project and have realized a few improvements that could be made. One improvement that we think would be beneficial is calculating two forms of riparian vegetation departure as follows:

  1. Riparian loss = (proportion of area with existing riparian vegetation [including nonnatives]) / (proportion of area with historic riparian vegetation)
  2. Invasive encroachment = (proportion of area with existing native riparian vegetation) / (proportion of area with historic native riparian vegetation)

We believe that this change will give a better understanding of what is driving vegetation changes on the ground.

These new fields will be RIPAR_DEP for point 1 described above and NATIV_DEP for part 2. NATIV_DEP is equivalent to the previously calculated DEP_RATIO and represents the change in native riparian vegetation.

This problem has been fully addressed in RCAT Version 2.0.
