.cengage.cam 0' ‘CENGAGE MiNDTAP Unit #1 1 Problem Set: Saving Ecosystems Aithough forest fires are an uncommon natural occurrence in tmpicai regions, they are prevalent in bareal forests andsome temperate forests. In fact, fires are part of the naturai ecosystem of boreai and temperate forests because lightning strikes ofien triggerthem. Periodic fires reduce the amount of fuel and keep the fires from developing into destructive fires.As a result, these forests oten contain species that are fire adapted, meaning they can withstand fire and evenbenefit from periodic low-intensity fires. Examples of fire adaptation include thick bark and high canopies.Additionaily, many pinecones open only in the presence of fire. In 2011, a very powerful wildfire spread to the edge of the White Mountain Apache Tribe’s land, located in easternArizona. Read about how the fire management strategies of the White Mountain Apache Tribe can affect the fireintensity in Arizona before completing the statements that follow. Ail of the tribe’s land management decisions, including those related to fire managementstrategy, are contmiled soiely by the tribe rattler than by multiple agencies. The tribe had beenperiodically clearing young trees. logging larger trees, and burning underbrush to replicate thenatural bumaandagrowth cycie of the Pondenosa pine forest on the tribal lands. Firefighterswere able to contml the fire only afier it reached tribal lands, due to a reduction in flameintensity. Because the tribe was periodically clearing tribal lands, this fire likely impacted trees than were affectedoutside the tribal lands. This is an exampie of careful 0. Search this course
