Unfortunately there is not much old growth left. A lot of the forest you see in Idaho, Washington, Oregon is too dense to resemble how the forests used to be. T

Unfortunately there is not much old growth left. A lot of the forest you see in Idaho, Washington, Oregon is too dense to resemble how the forests used to be. The spread of trees was more sparse historically, with bigger and taller trees (whose canopy prevented other growth underneath). It’s actually a part of why wildfires are a bigger problem now - dense forests means easier spreading of infestations (which create dry fuel) and also easier spreading of fires.
