Resilience vs Resistance

Resistance in fire ecology, to me, is the act of the vegetation or animal species being able to protect itself from the fire, essentially it resists being killed. That doesn't mean it doesn't get damaged in some way, it just means it has ways of protecting itself. My favorite tree, the California Redwood, has extremely thick bark that can protect its cambium during a fire (Agee 118). So it is resisting the fire killing one of the most essential parts of the tree. (Agee 131)

Resilience on the other hand can mean the vegetation lives or dies, but it doesn't go "extinct" for lack of a better word. It continues to regenerate after the fire (or whatever disturbance has happened). An example I can think of for this would be in germination (Agee 127). Some seeds are hard-coated and actually are dormant until there is a fire. I think this is a great example of why fire management is necessary. If there is fire suppression for these species, they don't have the opportunity to regenerate. I would think if an invasive species came through and killed this vegetation, it wouldn't have the opportunity to regenerate as the seeds are dormant within the soil.
