State of the Ecosystem (SOE) Reporting: Context for busy people

"So what?" --John Boreman, September 2016

  1. Clear linkage of ecosystem indicators with management objectives

  2. Synthesis across indicators for big picture

  3. Objectives related to human-well being placed first in report

  4. Short (< 30 pages), non-technical (but rigorous) text

  5. Emphasis on reproducibility

relating environment marine habitat and the marine community to human activities social systems and objectives

3 / 33

In 2016, we began taking steps to address these common critiques of the ESR model

Protected species

North Atlantic right whale abundance

1990-2018 right whale abundance estimates with 95\% credible intervals. These values represent the estimated number of animals alive sometime during the year referenced and NOT at the end of the year referenced. Three known deaths were recorded in 2018, but these deaths were not reflected in the 2018 estimate because those animals were alive sometime during the year. An additional 10 known deaths occurred in 2019.

New indicator

North Atlantic right whale calf births
