Equally, the topography also known as the physical feature of a certain geographical area, contributes to the direction in which a wildfire\u2019s flames burn, specifically by either burning faster uphill or slower downhill.[footnote]Ibid[\/footnote]\r\n\r\nWildfires can play an important role in maintaining balance among certain ecosystems, especially around the elimination of insects and diseases that can be deadly to various tree species. Similarly, they also provide a chance for survival and restoration of plant species. When wildfires burn \u201cat a low intensity, flames can clean up debris and underbrush on the forest floor, add nutrients to the soil, and open up space to let sunlight through to the ground [\u2026] [which can in turn] nourish smaller plant and give larger trees room to grow and flourish.\u201d[footnote]Ibid[\/footnote]\r\n\r\nWith a changing climate it is hence important to understand how the disruption to these ecosystems and natural pathways to manage homeostasis has played a role in more wildfires occurring, especially as a result of warmer temperatures that lead to drought and highly dry forested areas.\r\n\r\nTo start a wildfire, the following three components must be present, specifically:\r\n\r\n[caption id=\"attachment_257\" align=\"aligncenter\" width=\"1024\"]<img class=\"wp-image-257 size-large\" src=\"https:\/\/pressbooks.bccampus.ca\/bcwildfires\/wp-content\/uploads\/sites\/1669\/2022\/05\/firetriangle-1-1024x821.jpg\" alt=\"\" width=\"1024\" height=\"821\" \/> <a href=\"https:\/\/psychonautwiki.org\/wiki\/File:FireTriangle.png\">The Fire Triangle <\/a> Source: Fishcenternicole\/<a href=\"https:\/\/psychonautwiki.org\/wiki\/Main_Page\">PsychonautWiki<\/a> Licensed under <a href=\"https:\/\/creativecommons.org\/licenses\/by\/4.0\/\">CC By Share-Alike 4.0<\/a>[\/caption]\r\n\r\n&nbsp;\r\n\r\n<\/div>\r\n&nbsp;\r\n<div class=\"history-of-notable-wildfires-in-british-columbia\">\r\n\r\n[caption id=\"attachment_133\" align=\"aligncenter\" width=\"1024\"]<img class=\"wp-image-133 size-large\" src=\"https:\/\/pressbooks.bccampus.ca\/bcwildfires\/wp-content\/uploads\/sites\/1669\/2020\/06\/Composition-of-wildfire-smoke-particulate-matter-PM2.5-1024x765.png\" alt=\"\" width=\"1024\" height=\"765\" \/> <a href=\"http:\/\/www.bccdc.ca\/health-info\/prevention-public-health\/wildfire-smoke\">Wildfire Smoke Composition<\/a> Source: Jen Burgess\/IsolineStudios for BCCDC 23[\/caption]\r\n\r\n<\/div>","rendered":"<div class=\"history-of-notable-wildfires-in-british-columbia\">\n<p>The current 10-year average, taken from 2011 to 2020, is 1,352 <a class=\"glossary-term\" aria-haspopup=\"dialog\" aria-describedby=\"definition\" href=\"#term_169_360\">wildfires<\/a> from April 1st to March 31st the following year.
