Based on the study of the mechanism of biotechnical slope protection,mechanical model were developed in the condition of surface soil reinforced with herb-root in geo-grid.
And since they show few signs of burning above ground, they're incredibly difficult to track until they ignite dry surface soil, potentially miles away from the source.
The study " provides useful data about surface soil properties" , says Xiao Long, a planetary geologist at the China University of Geosciences in Wuhan.
