Role  of  Fire  in  Ecosystems  !  Nutrient  cycling  

!  Stimulation  of  seed  production  and  plant  germination  

!  Control  invasive  species  eg.  Scot’s  broom  

!  Reduction  of  pests  

!  Creates  complex  ecosystems  

!  Prevents  encroachment  of  less  fire  adapted  species  

!  Reduce  risk  of  catastrophic  fire

Principals  of  Ecological  Fire  Use  ! Allow  fire  to  act  in  its  natural  role  

! Fire  Regime  ! No  fixed  return  interval  (1-­‐3  years)  

! Carefully  Reintroduce  Fire  ! Create  artificial  mosaics  as  fire  re-­‐introduced    

Conclusion  

! Prairie  Restoration  is  Difficult  NOT  Impossible    

! Key  Focus  Conserve  What  Remains  

! No  Fire  =  No  Prairie
