Finally, he defined a minimum viable population (MVP): “A minimum viable population for any given species in any given habitat is the smallest population having at least a 95% chance of remaining extant for 100 years despite the foreseeable effects of demographic, environmental, and genetic stochasticity, and natural catastrophes.”[ 22 ] Both numbers (95% and 100 years) are conventional, and to be determined by social choice, rather than by biological factors, a point that Shaffer explicitly recognized.
