Biodiversity conservation - We need better metrics rigorously tested

The different t metrics, that we use, such as species abundance and extinction risk, paints different impressions of conservation success.

These metrics may include existing as well as new ones and must undergo rigorous testing to ensure that they are suitable for our conservation aims
