Estimating Species Frequency

  • DAFOR standing for Dominant, Abundant, Frequent, Occasional, Rare is a quick way of measuring coverage or frequency of a plant taxon=* within a given area. The dafor=* tag may require require measuring an area or use of a quadrat but is generally a rough estimation of plant coverage. For instance dafor:Ganzia rigens=* Dominant or dafor:Fagus sylvatica=*Occasional.
  • 'The trick to doing this is to go through the list quickly and for each species write the first score that comes into your head. Try not to think about it too much' [1]
