Summary
The smallest population size with a high chance of long-term persistence.
In depth
Often cited rules of thumb: 50 for short-term inbreeding avoidance and 500 for long-term evolutionary potential (50/500 rule), later revised upward to 100/1000. Depends on species.
MVP depends on goals and risks. Genetic needs (Ne) are lower than census size. Revised estimates are thousands for long-term persistence.
Remember: effective population size is usually smaller than census size.
