Age class structure

These models allow for the prediction of growth or decline in a population based on current conditions or future management practices.

[1] Removal of older individuals and males will increase the population by opening up resources for reproductive females and juveniles.

[7] Often fish in younger age class structures have very low numbers because they were small enough to slip through the sampling nets, and may in fact have a very healthy population.

[8] This could skew class structure data and result in imaccurate management techniques.

This shift in age class structures can also help predict how quickly the forest will rebound from the disturbance.

Age class structures can be used to determine when wildfires occurred within a forest population.
