Answer: ominous
Explanation:
In this paragraph, the word forbiding means the same as ominous. Ominous simply means that something that's threatening or bad.
From the passage, we are informed that a "dark and forbidding wood of giant arborescent ferns rose". This gives us the impression that there's something threatening there and that's an ominous sign.
