DescriptionGrand Canyon National Park Hazardous Fuels Reduction 0802 (5999256115).jpg |
Monitoring burn piles. August 1, 2011 - Weather conditions today permitted South Rim fire crews to continue burning piles of woody debris in the vicinity Market Plaza. The piles were constructed over the winter and early spring as part of a manual thinning, hazardous fuels reduction project intended to create defensible space in the park’s wildland urban interface. The project created a raised and more open tree canopy around the developed areas, as well as reducing dead and down fuels. In the event of a wildfire, these changes in the vegetation structure will inhibit the spread of fire and the likelihood of high-intensity fire behavior. The burn piles consist of small diameter tree trunks, small branches, twigs and needles removed during thinning and limbing operations. They will be ignited during, or immediately following, periods of precipitation and will be monitored by firefighters until they are completely out. Park visitors may see fire vehicles and personnel in the vicinity when piles are being burned, and may see open flames or smell smoke. Fire managers will strategically ignite the piles in an effort to keep smoke impacts to a minimum. Coordination with the Arizona Department of Environmental Quality is currently underway.
