Information

Ecological parameter:  rare species

Parameter group: ecoregion related parameters

Explanation:
The category of rare species is based on both a spatial and temporal scale: species range, historical records (in specific ecoregions) and current number of records (in different ecoregions). It is a non-scientific and rough approach as demographic data like population size, number of metapopulations etc. are not available in a detailed way.

Classification system: modified presence/absence assignment system
