- 1. Identification of Suitable Mountain Lion Habitat and Road Crossings Enrique Gutierrez | Kate Keeley | Jessica Sanchez | Yajaira Visoso | George Yoo Geography 170 Final Project
- 2. Mountain Lions (Puma concolor) Largest cat in North America Umbrella species Population control Charismatic species Not threatened or endangered "Specially protected species"
- 3. Specially Protected Species Specially designated as needing protection though total population isnt threatened Used to be widespread in Southern CA Now, only ~20 in Los Angeles/Ventura area
- 4. www.urbancarnivores.com
- 5. [insert map of SMM roads]
- 6. Solution: Wildlife Corridors
- 7. Basic Research Questions
- 8. Included: Watershed analysis Suitability Analysis Human Development: Human Infrastructure Hiking Trails Private/Public Land Hazards: Fire Hazard Zones Sewer Locations Included: NDVI Human Development: Slope Hillshade Vegetation Type
- 9. Suitability Analysis 1.) Select top two ranked fragment type 2.) Select fragments that are within 1 mile of roads 3.) Create fragment heatmaps to identify important areas 4.) Identify largest range intersected by roads 5.) Create point layer of important crossing locations
- 10. Inputs: Physical Watershed analysis: DEM + Lakes of SMM Fill Flow Direction Flow Accumulation Stream Raster Stream Link Streams in SMM
- 11. Inputs: Physical
- 12. Inputs: Physical
- 13. Inputs: Physical
- 14. Inputs: Physical
- 15. Inputs: Physical
- 16. Inputs: Human Development
- 17. Inputs: Hazards
- 18. Suitability Analysis: Input Rankings Streams: inside0.1 mile buffer = ranked 10; outside 5 miles = ranked 1 Vegetation type: trees = 10; developed = 0 NDVI: highest value = 10; lowest value = 1 Hillshade: shade = 3; no shade = 1 Human structures: outside 1 mile buffer = 3; inside 1 mile = 1 Hiking trails: outside 1 mile = 5; inside 0.25 mile buffer = 1 Land type: public = 5; private = 0 Sewers: outside 50 mile buffer = 5; inside 0.5 miles = 1 Fire hazard: no hazard = 5; extreme hazard = 1
- 19. Suitability Analysis Results
- 20. Suitability Analysis Results
- 21. Fragment Hotspots Near Roads
- 22. Fragment Hotspots Near Roads
- 23. Best Crossing Locations: Scenario 1
- 24. All Fragment Hotspots
- 25. Best Crossing Locations: Scenario 2
- 26. Best Crossing Locations #1 Choice #2 Choice #3 Choice (different depending on scenario)
- 27. Are these crossing locations at risk?
- 28. Are these crossing locations at risk? 1970 Fire Perimeters 1965-2013 Import into ArcMap Include temporal data Import into Tracking Analyst Enable playback manager Fire perimeters focus on physical geography Provide historical context
- 29. 1980 Are these crossing locations at risk? 1990
- 30. 2000 Are these crossing locations at risk? 2005
- 31. 2010 Are these crossing locations at risk? 2013
- 32. Conclusions Road Crossing Locations 1.) N1 Malibu Canyon Rd Site of frequent fires (3 in the last 30 years) 2.) Route 27 -- Topanga Canyon Rd 3.) Route 23 Takes into consideration many important factors to find the most critical road locations to connect vital habitats
- 33. QUESTIONS? Enrique Gutierrez | Kate Keeley | Jessica Sanchez | Yajaira Visoso | George Yoo Geography 170 Final Project
