Druid domains?

[GimliFett]

I can't seem to find the book and the domains available for the optional feature of giving Druids a domain from a specific list. Any help would be appreciated!

I'm not sure where that alternative feature appears, though if I were your DM I'd just get Obad-Hai's (or your setting's True Neutral Nature deity) domain list. Obad-Hai gets Air, Animal, Earth, Fire, Plant, and Water.

This isn't an alternative class feature at all. It's a house rule that happens to be printed on page 68 of Unearthed Arcana, where it lists 7 core Cleric domains and some suggested alterations of them for Druids.
