Field Leaf Area Index (LAI) Measurements for Estimating Fuel Loads
Southwest semidesert grasslands are highly affected by a century of livestock grazing, disruption of historical fire regimes, prolonged drought, and non-native plant invasions. The USFWS has sought to rehabilitate semidesert grasslands in Buenos Aires National Wildlife Refuge in southern Arizona. Prescribed burns have been used extensively for the past three decades to enhance habitat conditions and restore grassland fire regimes.
