Compare areas is a simple tool that will show the differences between any two defined areas in terms of species composition and area. Areas can be generated or determined by any of the options available under Add to Map | Area. Use these options to define the 2 areas you are interested in.


The inputs to the standard wizard are:

  1. Species, species list or lifeform (if you wish to limit the comparison to specific species)
  2. Identity of area 1
  3. Identity of area 2
