Declining Populations of Plants

About this Page

  • ZipcodeZoo detects declining populations by comparing two observation rates: the number of observations reported for the species each year, and the number of observations reported for that species' taxonomic Class each year. If the species is a declining percentage of all such observations, we have good reason to suspect that this change is a result of population decline.
  • These findings are machine-generated, and are only suggestive. For each of the species listed below, further research may be appropriate. For more info about our analyses, click here.
