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.
If you assume something about someone, you could be acting on false information and that can lead to trouble.
