Grazing strategy could be key to reducing wild land fires, researchers say

New Mexico State University researchers and experts from other universities are looking into the possibility that a targeted grazing strategy for range cattle could significantly reduce the risk of catastrophic wildfires. "Behavior of wildfires is affected by the abundance of what we call 'fine fuels,'" said NMSU rangeland expert Derek Bailey. "Our assumption is that moderate levels of grazing can be used to strategically reduce the levels of fine fuels and correspondingly limit impacts and economic losses of wildfire." Bailey teaches in the Department of Animal and Range Sciences and is the director of NMSU's Chihuahuan Desert Rangeland Research Center north of Las Cruces. He and other investigators are halfway through a three-year study on targeted grazing. Targeted grazing at four locations in New Mexico and Arizona involves manually herding cattle into more rugged and remote areas of fuel buildup and determining if the availability of forage, along with the strategic positioning of protein supplement blocks, encourages the animals to spend a higher percentage of their time away from the overgrazed areas around their water source. Preliminary results suggest that the combination of herding and strategic supplement placement can effectively reduce biomass of fine fuels, Bailey said...more
