  1. 1. Wildland Fire Prevention Louis Rene’ Barrera, Preserves Management Coordinator Austin Nature Preserves System Natural Resources Division Parks and Recreation Department City Of Austin, Texas
  2. 2. Purpose <ul><li>Protection of high value resources from wildfire. </li></ul><ul><li>Focus fire prevention activities, cost efficiently, in the priority areas. </li></ul><ul><li>Minimize losses, by effective implemenrtation of the planned actions. </li></ul>
  3. 3. Fire Prevention Analysis <ul><li>Risk </li></ul><ul><li>Hazards </li></ul><ul><li>Values </li></ul>
  4. 4. Risk <ul><li>Risk are defined as the potential for a wildland fire ignition. </li></ul>
  5. 5. Hazards <ul><li>Hazards-are defined as the fuel and topography of an area. </li></ul>
  6. 6. Values <ul><li>Values in this process are the rankings of the differences in value of planned resource outputs of an area before and after a fire. </li></ul>
  7. 7. Wildland Fire Prevention Areas <ul><li>EDUCATION </li></ul><ul><li>ENGINEERING </li></ul><ul><li>ENFORCEMENT </li></ul><ul><li>ADIMINISTRATION </li></ul>
  8. 8. Education <ul><li>Education is aimed at changing people’s behavior by awareness and knowledge </li></ul>
  9. 9. Engineering <ul><li>Engineering is an activity designed to shield an ignition source ( e.g., spark arrester) or remove the fuel which could ignition from a spark or fire brand ( clearance around a home) </li></ul>
  10. 10. Enforcement <ul><li>Enforcement is used to gain compliance with fire regulations and ordinances. </li></ul>
  11. 11. Administration <ul><li>Administration- those activities such as planning, budgeting, and training. </li></ul>
  12. 12. Urban Wildland Interface, UWI <ul><li>“ An area where structures and other human development meet and or intermingle with vegetative fuels in undeveloped wildlands.” Colorado State Forest Service </li></ul><ul><li>“ It’s where combustible vegetation meets combustible homes.” A Family Oriented Wildfire Preparedness Program 2003 -Texas Forest Service </li></ul>
  13. 13. Model of Risk <ul><li>Potential for ignition </li></ul><ul><li>Potential to burn and </li></ul><ul><li>Potential human consequence. Wildfire May 1, 2004, Baum, K. </li></ul>
  14. 14. Types of risk <ul><li>Small or Low </li></ul><ul><li>Medium or Moderate </li></ul><ul><li>Large or High </li></ul>
  15. 15. Types of Fire <ul><li>Surface </li></ul><ul><li>Ground </li></ul><ul><li>Crown fires </li></ul>
  16. 17. Some examples of risks in preserves and parklands <ul><li>Illegal dumping of household materials </li></ul><ul><li>Pit fires/ brush pile fires (invasive and native) </li></ul><ul><li>Grass fires </li></ul><ul><li>Ladder fuel </li></ul><ul><li>Crown fires </li></ul><ul><li>Anderson Type 4 vegetation, Ashe juniper </li></ul><ul><li>95% fires human caused </li></ul>
  17. 18. Defensible Space Defensible space is an area surrounding a home where the vegetation, and sometimes the structure itself, has been modified in order to separate the “ fuels” upon which a wildfire feeds. A Family Oriented Wildfire Preparedness Program 2003 -Texas Forest Service
  18. 19. Defensible Space*
  19. 20. Draft guidelines for land uses adjacent to Natural Areas <ul><li>Fire wise landscape and building specifications </li></ul><ul><li>No wooden shingles </li></ul><ul><li>No overhanging patios in wildland interface </li></ul><ul><li>Spark arrestors for chimneys </li></ul><ul><li>No gates or access into preserves without proper authorization </li></ul><ul><li>Fencing design specifications </li></ul><ul><li>No residential/ commercial brush disposal on public property </li></ul><ul><li>No alteration of parklands or endangered species habitat </li></ul><ul><li>No alteration of pre- existing environmental conditions. </li></ul><ul><li>No combustible fuel sources in or near preserves </li></ul>
