Pros & Cons

3 Pros:

  • Image: Combined relative mean species abundance of original species (MSA), using all pressure factors.
  • Data are easy to perceive and intuitively understandable
  • Trend from 2000 to 2050 is easy to grasp

3 Cons:

  • No differentiation into classes of species
  • No detailed info on scenario assumption in image 
  • No comparison with absolute numbers of species prevalent in the same map grid element, which would allow still better assessment of situation
