I know a lot of people have made posts about backfilling, but I decided to make a new post anyway in order to compile a comprehensive list of existing species that I'd personally like to see added to the existing maps. Please note that I'm not going to mention anything for Vurhonga because that map would be better suited to the addition of new species, not any existing ones. So, here's the species I'd like to see backfilled onto each reserve. I'll explain my choices in detail in the thread below.
European Mouflon, Chamois, Western Capercaillie, Eurasian Teal and Tufted Duck (Hirschfelden)
Red Fox, Green-Winged Teal, Mountain Goat, Bighorn Sheep and Mountain Lion (Layton Lake)
Black Grouse and Hazel Grouse (Medved Taiga)
Fallow Deer and Wild Boar/Feral Pig (Parque Fernando)
Black Bear and Willow Ptarmigan (Yukon Valley)
Fallow Deer (Cuatro Colinas)
Coyote, Ring Necked Pheasant, Cinnamon Teal and White-Tailed Jackrabbit (Silver Ridge Peaks)
Canada Goose, Sambar Deer (Te Awaroa)
Gray Fox (Rancho Del Arroyo)
Mallard and Bobcat (Mississippi Acres)
Roe Deer (Revontuli Coast)
Canada Goose (New England Mountains)
Water Buffalo and European Rabbit (Emerald Coast)
