The Live Woody Moisture map displays the % moisture content on a dry-weight basis of live woody fuels. Woody fuels are divided into evergreen and deciduous, and refer to the leaves, needles, and twigs of woody shrubs and trees. In contrast to dead fuels, live woody fuels contain some greenness and moisture content is controlled largely by physiological processes within the plant. Deciduous live woody fuels go through an annual cycle, at the end of which the leaves and twigs become dead fuels for purposes of fire danger modeling. During the growing season, low soil moisture can cause these deciduous fuels to decrease in fuel moisture and can cause evergreen fuels to decrease in fuel moisture anytime throughout the year. Because live fuels consist mainly of water, fuel moisture values can go well over 100%. Live woody moisture is crudely modeled as a function of relative greenness for each 1-km square pixel of land and can range from 70-160%. This map is updated every Tuesday when the new weekly satellite data is processed.
