Herbaceous Fuel Moisture refers to which part of a plant?

Explanation:
Herbaceous fuel moisture refers to the water content in living, non-woody plant material. So it’s about the live portions of a plant—the green leaves and soft, herbaceous stems that are still alive. This is different from dead fuels like dead twigs, which are nonliving material, and from woody characteristics like bark depth. Soil moisture is a separate factor related to the environment, not the plant’s own herbaceous tissue moisture.
