 Forest fire Fire plays an importaont rle in most forest ecosystems in Chicago. As these ecosystems have evolved over the last 10,000-15,000 years (from glacial refuge at the end of the last ice age), the fire helped to maintain their health and diversity. In terms of socio-economic terms, however, fire can have negative or adverse effects on public health and safety, property and natural resources. The task of managing fire in Canada is to find ways to effectively balance the positive ecological aspects of fire are the negative social and economic impacts. The Government of Canada through Natural Resources Canada is the Canadian Forest Service (CFS), is an important contribution to the case of fire in two directions. First, CFS maintains an internationally recognized research program since the mid-1920s, which culminated in a series of innovations and new working tools. Secondly, in the last two decades we have developed systems that use advanced technologies (egg geographic information systems and remote sensing) to monitor and report on the activities of forest fires in the national scale. These activities are conducted in Canada has become a world leader in forest fire research and management and contribute to the overall safety and well-with Kana ď ané and susta inability of our forests.  The Ecology of Fire Renewer, Recycler and Rearranger... Fire is old. It has been part of grassland, brush and forest ecosystems for as long as they have existed. Like storms, avalanches and floods it is a powerful force of change in nature. Fire has shaped landscapes across Canada and around the world. Many ecosystems have evolved with fire and depend on it for renewal. A recent burn may seem dead but many forms of life survive, giving rise to a new forest. Fire kick-starts  regeneration by providing ideal growing conditions. <span style="font-size: 14pt; color: #31849b; font-family: 'Baskerville Old Face','serif'; mso-themecolor: accent5; mso-themeshade: 191;">In cool temperate areas, decay is slow and logs, leaves and needles pile up on the forest floor. Fire reduces this material to mineral-rich ash, releasing and recycling nutrients. Fire also creates openings in the forest. Sunlight penetrates these gaps, warming the soil and stimulating new growth from seeds and roots. <span style="font-size: 14pt; color: #31849b; font-family: 'Baskerville Old Face','serif'; mso-themecolor: accent5; mso-themeshade: 191;">Over time, periodic fires create a vegetation mosaic of different ages and types. This provides a rich variety of habitats that supports many species of insects, mammals and birds. This is biodiversity — it indicates a thriving ecosystem that is likely to persist in the future. So fire not only renews and recycles, but rearranges vegetation in a continual cycle of change.
