The process of grassland curing can significantly impact the likelihood of ignition and the rate of spread of a grass fire. The degree of curing, expressed as a percentage by weight, is one of the key inputs to fire spread models and fire danger rating systems such as the McArthur (1977) Grassland Fire Danger Meter. Many jurisdictions have relied on visual estimates of curing percentage, typically provided by regional volunteers, as an efficient alternative to weight based estimates of curing.
