True or False: Dead grass reacts like 1 hour timelag fuel.

The statement is true because dead grass does behave like 1-hour timelag fuel in terms of its moisture content and response to changes in environmental conditions. Timelag fuels are categorized based on their moisture content and the time it takes for these fuels to respond to changes in humidity and precipitation.

1-hour timelag fuels are those that can reach equilibrium with the environment within about one hour. This characteristic primarily applies to fine fuels, such as dead grass, light shrubbery, and small twigs, which can dry out and absorb moisture rapidly. Consequently, dead grass, being a fine fuel, has a similar reaction to moisture changes as 1-hour timelag fuels, efficiently igniting and burning under dry conditions and quickly dampening when exposed to moisture.

This congruence in behavior underscores the importance of understanding different fuel types and their classifications in fire behavior, supporting effective fire management strategies.
