Annual Occupation Factor of the Sites

For enhancing the relation between number of sites known eac year and number of sites really occupated, we have calculated an Annual Occupation Factor : CAO = Nb occupated sites/ Nb known sites.

This ratio trends towards 1 when a maximum of known sites are occupated.

The opposite chart represents the evolution of the Annual Occupation Factor from 1988 (beginning of the regular monitoring of the Mezenc marmot population) to nowadays.
