2019-03-12 P&E Agenda - Item 5 - Attachment 2 - Koala Infrastructure & Feasibility Report

           o Car hit by date
                  ▪ 2014-2016 = 5
                  ▪ 2012-2014 = 4
                  ▪ 2010-2012 = 3
                  ▪ 2000-2010 = 2
                  ▪ Pre2000 = 1
•    Perform kernel density (200m) on sightings and on HBC
•    Reclassify sightings grid and hbc grids back to 5 natural break classes?
         o Reclassify
         o 0-2 = 0
         o 2-15 = 1
         o 15-50 = 2
         o 50-500 = 3
         o >500 = 4
•    Mosaic sighting and HBC grids using Max value = denmax

Combined road risk - high connectivity and Density

Connectivity + Max Density = denmax_con (total risk) values from 0-10 with 10 being highest risk i.e. High
density of sightings or recent car hits and high connectivity.

•    Convert demmax_con to poly
•    Intersect demmax con poly with Road types 1-4 and 5 (slower streets are still important particularly in
     built-up areas around core habitat/multiple sightings, possibility to reduce speed limit or have signs or
     even slow designs

Show values 5-10. Hotspots >=5

5 – generally high connectivity (middle of core hab) or otherwise large concentration of koala sightings

10 – high connectivity and high sightings/recent car hits
