6 in 1 challenge pt1

Pt1 of the new 6 in 1 challenge i made for myself. The rules are simple create a large habitat for each region of the world then divide them all into 6 fully functional habitats with maximum welfare. Pt 1 of my attempt showcases North America with the 6 habitats being divided among bears,wolves, moose,couger,beaver and a shared habitat for bison and pronghorn. If you want to attempt this challenge yourself feel free. Any suggestions on which region i should attempt for the next 6 in 1 let me know
