Exotic plants and animals are mainly introduced in an area by people. For example, about 25 million homes in the US have exotic birds as pets –…

Wildlife & Range Management

Rangelands occupy about 47% of the world’s land area. They characteristically are unsuited for cultivation, but produce forage for livestock and wildlife. In the US, rangelands occupy about one-third of the country – much of it public land in the 17 states west of the Mississippi River. Management of Range Vegetation Range vegetation is managed…

Harvest should be a replacing form of mortality, it should replace some of the mortality which…

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…

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….

Natural Selection

Since our last discussion, have you ironed out your wildlife philosophy? If not, don’t worry – it took me years of both academic and real-life experiences to help me fine tune my own beliefs. We’ll keep working on it! In this post, we’ll discuss Wildlife Management and the Concept of Natural Selection. A basic concept…
