Fuel moisture content is essential to estimate several fire behavior variables. The objective of the present study was to estimate fuel moisture through me- teorological variables. The field materials used for this purpose were the accu- mulated needles found on the ground of a Pinus elliottii Engelm. plantation of the Federal University of Paraná Experimental Station, located in Rio Negro county, Paraná State, southern Brazil (26º04’S lat., 49º45’W long.). To de- termine fuel moisture content, two sampling methods were tested: the first method consisted in collecting samples of fuel in plastic baskets and sub- sequently weighing them approximately every two hours, while the second method consisted in collecting, approximately every two hours, a series of dif- ferent samples directly from the forest floor, and weighing them. All the samples collected on site were then oven dried for moisture determination. Comparing both methods, it was found that the best results were obtained u- sing the samples collected directly from the forest floor and that the best fit- ting equation included air temperature and wind speed.
