The Guardians of Hyjal are actually a collaboration between the druids of the Cenarion Circle and the Green Dragonflight. They've banded together to protect Hyjal from any would-be villains and to ensure Nordrassil's survival. With the uprising of Ragnaros in the region, it would seem that the group is sorely needed -- and as a faction in Cataclysm, players can join up with these guys and cash in on reputation rewards.
And if you really like the look of Hyjal's plate defenders, it's actually pretty easy to replicate it with transmogrification!
