Fire Adaptations: Legacy of Coexistence

Fynbos plants exhibit a phase of traits that allow them to contact or even benefit from fire. These fall into two main strategies:

  • Resprouters: Xi1; Xi1; FLT: 0 Xi3; Xi3; FLT: 1 XI3; Xi3; Many XRZ, such as certain Restios andd geophytes, have underground storage organs or thick bark that protect buds. After a fire, they resproud t energy ously from the base or frem rhizomes.
