I am posting this because I couldn't find a decent guide when I was trying to get this achievement in this alliance. I hope this helps someone, and if anyone can fill in the blanks or knows of any better locations for this please comment and help your fellow hunters.
My goal for these locations was basically to find the lowest level area with the highest density of creatures. The faster the better because this took me a long time to do.
Keep in mind that as the game currently stands only one person can get kill credit for this at a time. Meaning that even if a creature drops loot for you and your friend, only one of you gets credit for it for the achievement. This is something best done solo unfortunately, which is why I have not included any locations in Craglorn or 4 person dungeons.
Good Luck and Happy Hunting!

Dwarven Construct Slayer:
Spiders:Stros M'kai-Bthzark (Either go in circles in the first room, or if someone is in there go outside to the bridge on the left and there's a ton out there)
*ssfiit found dwemer ruins in Deshaan that are lower level. Bthanual and Mzithumz.*
Daedra Slayer:
Beastial/Humanoid:Auridon-Mehruen's Spite (Didn't need to farm this one myself so not sure if that's the best place)
Flame/Storm/Frost Atronach:Reaper's March-North of Willowgrove
Flesh Atronach:Malabal Tor-Around Abamath
Undead Slayer:
Skeletons:Auridon-Soulfire Plateau
Zombies:Eastmarch-Bonestrewn Crest (Best area I could find that wasn't being farmed out of control. Drauger there are not too hard.) You can also try coldharbour around the Vile Laboratory, but you probably won't get credit for many kills.
Ghosts/Spirits:Auridon-Outside Tanzelwil
Vampires:Auridon-Inside Ondil
Nature Slayer:
Insect Like:Kenarthi's Roost-Laughing Moons Plantation(Thunderbug)
Lizard Like:Kenarthi's Roost-Beaches (Alit)

Water Based:Reaper's March-Waterdancer Falls (Nereids. The boss does not count but her two adds do)
Chitinous:Kenarthi's Roost-Beaches (Crabs)
Netches:Cold Harbor-Around Court of Contempt (Betty's are way easier than bulls)
Humanoid Slayer:
Humanoids:Kenarthi's Roost-West Coast (Sea Elves. Another one I didn't need to farm, but that seems like a good spot)
Goblin-kin:Auridon-Toothmaul Gully
Giant-kin:Eastmarch-Lower Yogrim
