Predator Reintroduction
Scenario Simulator

Explore population viability for large predator reintroduction scenarios across Utah wilderness areas. Powered by a modified Leslie matrix model with stochastic environmental and demographic variation. Each run executes 200 independent Monte Carlo replicates to generate confidence intervals.

Population trajectory
200 stochastic runs · median with 50% and 80% confidence intervals
Inbreeding coefficient (F) trajectory
Wright (1931) approximation: ΔF = 1/(2Nₑ) per generation. F > 0.10 indicates significant inbreeding depression risk.
Cumulative extinction probability
Proportion of 200 simulation runs where the population reaches zero by each year.
