1.1 The value of computer modelling

We have the ability to think and contemplate the world around us. Whether out on the land, working, studying or learning - thinking about our world is the essence of modeling. It’s using what you know to understand more about what you may not know.


1.2 Understanding population dynamics

Wildlife population models can be quite simple and straightforward. As we add more detail to a model, the only to do the hundreds and sometimes thousands of calculations needed is with a computer. We can think of computer simulation models as tools that help us visualize and represent the thinking we already do.

2.1 Natural mortality and sustainable harvesting

We introduce the concept of sustainable harvesting (hunting and trapping) as it applies to northern wildlife populations. Then we highlight and identify how natural and human causes of mortality may affect levels of sustainable harvesting in wildlife populations.

2.2 Harvest management issues

In populations with high year to year variability, such as many northern wildlife populations, a conservative strategy is to reduce the overall rate of harvest to minimize the risk of overharvest during years when animal abundance is naturally low.

2.3 Sex ratio and population productivity

The adult sex ratio of a population affects herd productivity and therefore has implications for harvest management strategies.

3.1 Building a landscape & wildlife population model (Part 1)

Wildlife live in dynamic landscapes that change due to natural disturbances and human land uses. It is important to consider these natural and human-caused changes in the landscape, because the resulting habitat changes may affect population trends and influence options for sustainable hunting.

3.2 Building a landscape & wildlife population model (Part 2)

Wildlife managers need to understand population information to learn more about options for harvest management.

4.1 Harvest Management Strategies (Part 1)

How environmental and habitat variability might affect harvest management strategies.

4.2 Harvest Management Strategies (Part 2)

Effects of harvesting males versus females on wildlife populations.
