1. 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. 2. Mountain Lions (Puma concolor) Largest cat in North America Umbrella species Population control Charismatic species Not threatened or endangered "Specially protected species"
3. 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

5. 5. [insert map of SMM roads]
6. 6. Solution: Wildlife Corridors
7. 7. Basic Research Questions
8. 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. 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. 10. Inputs: Physical Watershed analysis: DEM + Lakes of SMM Fill Flow Direction Flow Accumulation Stream Raster Stream Link Streams in SMM
11. 11. Inputs: Physical
12. 12. Inputs: Physical
13. 13. Inputs: Physical
14. 14. Inputs: Physical
15. 15. Inputs: Physical
16. 16. Inputs: Human Development
17. 17. Inputs: Hazards
18. 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

28. 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. 29. 1980 Are these crossing locations at risk? 1990
30. 30. 2000 Are these crossing locations at risk? 2005
31. 31. 2010 Are these crossing locations at risk? 2013
32. 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
