Prairie Restoration on Joint Base Lewis McChord

  1. 1. Prairie  Restora+on   on  JBLM   JBLM  Fish  &  Wildlife   Program  Mission:     maintain,  and  enhance   the  various  ecosystems   on  the  installation  to   promote  native   biodiversity  and  support   the  military  mission.   John  Richardson   Joint  Base  Lewis-­‐McChord   Fish  and  Wildlife  
  2. 2. ≈97%  Of  Prairie   Habitat  Lost  
  3. 3. Types  of  Habitat  Loss   Habitat  Degradation   Forest  Encroachment     Urban  Development   Conversion  to  Agriculture  
  4. 4. Prairie  Restora7on   3  Phases   !  1st  Phase  Removal  of   Invasive  Species   !  3  Methods  of  Removal   !  Mechanical   !  Chemical   !  Fire   !  2nd  Phase  Planting   Native  Vegetation    
  5. 5. Plant  and  Seed  Produc7on   Seed  Beds   Sustainable  Prisons  Project  
  6. 6. Restore  Ecosystem  Processes   Corner  Stone  of  Prairie  Restoration  
  7. 7. Glacial  Outwash  Prairie   Ponderosa  Pine   Garry  Oak   Fire  Dependent  Ecosystems  in   Western  Washington   !  Adapted  to  Frequent  Low  Intensity  Fires   !  Historically  Maintained  Through  Burning  by  Native   Americans    
  8. 8. 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      
  9. 9. Typical  Low  Intensity  Fire  on  JBLM  
  10. 10. Before  and  AKer  Fire   2010   2011  
  11. 11. Habitat  Exclusions  
  12. 12. 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    
  13. 13. Conclusion   !  Prairie  Restoration  is  Difficult  NOT  Impossible     !  Key  Focus  Conserve  What  Remains   !  No  Fire  =  No  Prairie
