Purchased Naturalist role. Whats the best way to farm xp?

Whats the best way to farm naturalist role xp? Best location for sedating animals? Which animal field set is easy to farm?

I've been waiting for this Naturalist role month coz I can use the 3xp bonus, reach Rank 20 & use legendary animals skin for my trader business.

I dont care about the money or gold. I need tips only for the role xp. Thanks in advance.
