Query Species Evenness

 

Stratum

Life form:

   

Note: Pool 4 does not include 2003 data for backwater isolated or Lake Pepin strata.

Querying for vegetation evenness allows you to see how diverse the pools vegetation species are. It allows you to query based on lifeform and a year range. The diversity index and evenness are calculated using Shannon's diversity index where a value close to 1 means the pool is diverse and a value close to 0 means the pool is not diverse.
