stochastic simulation of population with removal/harvest

Just as we can use metapopulation models to study the probability of regional extinction, we can also study regional abundance and regional abundance trends.

4b. Change the Age 1 mortality rate to 0.3. Run the simulation starting with 75 individuals, all in Age class 1. What happens? Is this a stochastic model? If not, why does it look like it has a random component?
