Yavanna's "thoughts"

[Sophia the Thunder Mistress]

I have a question for those who have access to HoME. Tolkien breifly discusses the origin of the ents in the Silmarillion in Quenta Silmarillion ch. 2, but he also speaks of similar guardians for animals.

And Manwe said, "O Kementari, Eru hath spoken saying:'Do then any of the Valar suppose that I did not hear all the song, even the least sound of the least voice? Behold! When the Children awake, the thought of Yavanna will awake also, and it will summon spirits from afar, and they will go among the Kelvar and the Olvar, and some will dwell therein, and be held in reverence, and their just anger shall be feared..."

Since by kelvar she's referring to animals, I'd assume that there are guardians for animals that correspond to ents for plants. Does Tolkien amend this or elaborate at all about these guardians, where the spirits come from, or what happens to the ents/kelvar-guardians when they die? There seems to be provision made for the Dwarves of Aule, I've always wondered if there was something similar for the ents...

*tentative* the only vaguely related concept I can find that might correlate with ents is the Beornings?

Thanks much
