Description

Norway rats are one of the most destructive creatures known to man. They destroy and contaminate untold quantities of food, and through their tunneling activities, undermine the foundations of buildings, sewer and water lines, and city streets. Rats also weaken and deface buildings by gnawing holes through floors, walls, insulation and supporting structures. Norway rats carried the flea that spread plague throughout Europe and Asia. Even today, they spread organisms responsible for food poisoning, hepatitis, tularemea and other diseases. Thus, the people of Alberta are extremely fortunate not to have rats. This is not by chance but by design. For the past four decades, Alberta has had a program to keep rats out of the province. This publication describes the evolution, history and current status of the rat control program in Alberta, and discusses factors which contributed to its success.

Description

People generally relate skunks to the foul-smelling, defensive spray they discharge when scared or threatened. Generally, people avoid skunks and have little tolerance for their presence. In many parts of North America, skunks are also a major carrier of rabies. Rabies has been present in the skunk population of southern Alberta, at fluctuating levels, since the late 1970s. This information sheet includes a brief look at the biology, behaviour and reproduction of skunks, and then focuses on non-lethal and lethal methods of skunk control.

Description

Orchards, nurseries, shelterbelts and gardens can suffer economic losses and aesthetic damage because of gnawing animals. Most damage occurs from late fall until early spring when extreme weather conditions limit the available food supply. Plant damage can also be extensive during periods of drought or when rabbit and hare populations are high.

Description

The porcupine is Alberta’s second largest rodent, measuring up to 90 cm in length and weighing as much as 12 kg (Figure 1). They live throughout the province, usually near stands of woody vegetation. The porcupine has a unique defence mechanism of up to 30,000 hardened barbed quills built into its coat. The porcupine is an interesting animal that has an important place in the environment. Porcupines are edible and have been used by humans as an emergency food. The quills are used for decoration, especially by native Canadians. The hair is very popular among fly fisherman. Porcupines may need to be controlled but should not be totally eradicated.
