Wildlife & Harvest: Part I

Now its time to go over your personal feelings about hunting with a fine-toothed comb. Harvesting animals is one of the wildlife managers most useful and effective tools. Before we get into how harvesting (hunting, fishing, and trapping) fits into your tool belt (and your feelings about it), lets discuss the reasons why. In most…

Wildlife Diseases & Habitat Quality

There is a strong correlation between wildlife diseases and their habitats. Today we’ll discuss those diseases and how what’s surrounding them can contribute. More importantly, we’ll also go over diseases that can be passed to us humans and what we can do to prevent them. Before we get started, here are some concepts to keep…

Types of Wildlife Mortality

As a follow up from the last post, today we’ll go over the different types of wildlife mortality. There are many different ways your animals can die, when we discuss these ways, you can see how to prevent these types of mortality as much as possible. Starvation and Malnutrition: Starvation is death or debilitation caused…

Wildlife Mortality Concepts

There are many types of mortality that wildlife can succumb to. Mortality is merely the cause of death; some being normal and others abnormal. Today we will discuss the differences between the two and the general concepts of mortality that can damage your wildlife populations. Normal Mortality vs. Abnormal Mortality Normal Mortality: Types of mortality…

Population Size & Reproduction

Environmental factors that may influence the reproductive process (e.g., nutrition, weather, crowding, predation, disease) often have more severe impacts on reproductive success when wildlife populations are HIGH rather than low. Why? In large populations there is more competition for both quantity and quality of food and cover, which leads us into a discussion of density-dependent reproduction….

Reproductive Processes

The total annual reproduction by a wildlife population is generally determined by 7 items. Each item may be influenced by habitat conditions and environmental factors (e.g., nutrition, weather, stress, disease, etc.). Because of this, a wildfire manager may have to measure several aspects of reproduction to understand an animal’s reproductive successes or failures. So what are the 7…

Mating Systems

Today we’ll discuss the 3 types of Mating Systems: Monogamy, Polygamy, and Promiscuity! But first we shall go over sex ratios before getting into the main topic. Sex Ratios express the relative abundance of each sex in wildlife populations. Sex ratios are expressed as “the number of males: the number of females“ 50 : 50 even sex…

Wildlife Reproduction

In a stable animal population, reproduction must offset natural mortality – especially if the animals are harvested! It’s important for the wildlife manager to monitor reproductive success and be aware of the factors that can impact reproduction! Before we get started, here are some terms to know: Fecundity: Ability of an animal to produce eggs or…

Migration

We’ll finish up our discussion of movement with the second type of movement: Migration. Migration is a periodic movement involving a round-trip! There are two types of migration: Altitudinal Migration: animals migrate relatively short distances up and down mountains out west e.g., big game (elk, mule deer, moose) – their “summer” and “winter” ranges Latitudinal Migration: animals migrate a long distance;…

Wildlife Movements

A critical part of wildlife management is understanding how wildlife moves within its habitat. We will break down the first of the two types of movement: Local Movement. There are four main types of Local Movement: Home Range: a home range is the area traveled by an animal in its normal daily activities. An animal…
