Non-target Taxa Monitoring Ecological Risk Containment

“Supplementation is the use of artificial propagation in an attempt to maintain or increase natural production while maintaining the long term fitness of the target population, and keeping ecological and genetic impacts on nontarget populations within specified biological limits.”
