I believe it used to be quite forested.

I believe there were once NO giant redwoods. Maybe no minature ones either.

Yes and even swampy in places.

I believe it was the Greek historian Herodotus who mentioned that North Africa, which had been forested, was by then (~450 BC) a prairie supporting only rabbits and bees (or something like that.)

So it's been getting drier over the centuries.

Except I think, quite recently, it's begun to slightly green up again. Due to more adequate levels of CO₂?
