How many populations and combination of populations are there in the mapping tool?

 There are 295 populations and combination of populations in the mapping tool

  • These include objectives for individual ESA-listed and non-listed populations and objectives for combined populations, such as for an entire subbasin. Some population names may not match the NOAA ESA formal name. All names can be viewed  here. 
  • Each population (or combination of populations) may have one or more abundance objective value(s) from one or more document(s). Sometimes the same value is provided multiple times with a slightly different variable name. Other times there are multiple unique abundance objective values with different variable names  (e.g., near- or long-term objective).

How do multiple objectives for a population fit together?

For some populations with multiple objectives, the objectives fit together by ranging from a minimum abundance (small) to a larger sustainable abundance. Some populations may have some overlap in their numerical objectives or may not fit as neatly together. Below are 5 examples illustrating these variations.
