Bond with nature in this charming expansion pack means...

For those who are questioning Werewolves bonding to nature, I suggest you look up the TTRPG "Werewolf: The Apocalypse" (Werewolf: the Forsaken has similar themes) which presents Werewolves as the (very violent) guardians of the Natural World, fighting against pollution and Urban Expansion, among other evils.

So I can very definitely see Werewolves as bonding to Nature

But I don't see them as being particularly charming. :)
