10. 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
25. Are these crossing locations at risk?

29. Conclusions
Road Crossing Locations
1.) N1: Malibu Canyon Rd*
Site of frequent fires (3 in the last 30 years)
2.) 27: Topanga Canyon Rd
3.) N9: Kanan Dume Rd
Takes into consideration many important
factors to find the most critical road locations
to connect vital habitats
