The coastal redwoods (also massive) grow from central California to just over the Oregon border.
I'm not sure what you think a "forest" is, but I'm pretty sure the largest by height, largest by volume and largest by diameter trees on the planet would qualify.
And before you reeeeee over pic related- those are specific species, not the borders of forests.
And that's just for starters.
We could also talk about Ponderosa pines in the Sierra Nevada's
