Ice storms, also referred to as glaze storms, cause considerable damage every year to trees in urban and natural areas. They vary considerably in their severity and frequency. Ice storms are result of the ice formation process, which is influenced by general weather patterns. Ice accumulates when super cooled rain freezes on contact with surfaces, such as tree branches, that are at or below the freezing point (0'C). This generally occurs when a winter warm front passes through an area after the ground-level temperature reaches or falls below freezing. Rain falls through layers of cooler air without freezing, becoming super cooled. Periodically, other climatic events, including stationary, occluded, and cold fronts, also result in ice storms.

The purpose of this paper is to gain a better understanding of the1998 ice storm. This paper features three main section: An introduction, the main body (damage to woodland), and finally, a conclusion. In the main body of this paper, the effect of fire and pest/disease is discussed in detail. In the conclusion, comparison is made between fire and pests/disease versus ice storm. By the end of this paper, one should g

In the predominantly coniferous forests in western North America there are considerable areas undisturbed directly by human activities. In these areas, diseases kill trees or predispose them to other agents of disturbance, resulting in gradual change in stand composition and structure. In areas disturbed by forest management practices of harvesting or exclusion of fire, increased disease incidence and severity has increased the damage caused by disease, and consequently, the rate of change.

The term landscape refers to a 'group' or a 'family' of trees. I use the term vaguely because the size and composition of landscapes differ from region to region. The degree of damage is typically highly skewed by area. For example, in the January 1998 Northeaster storm, 1,800,000 ha of damage in Quebec was assessed by the Ministry of Natural Resource: very severe 4.2%, severe 32.0%, moderate 29.9%, and slight/trace 33.9% (The Science of the Total Environment, Volume: 262, Issue: 3, November 15, 2000, pp. 231-242 ). The effects on entire forest landscapes are highly patchy and variable. They also depend significantly on how landowners respond to the damage.
