But tree farms don't resemble a native forest, with its diversity of life. Mono-crops, like this Roseburg plantation in Shasta County, consist of almost entirely of the ponderosa pine. Foresters for Roseburg have insisted this is a diversified forest, despite what is plain to the eye.
Herbicides have eliminated the vegetation used by nesting animals and few hardwoods exist, being killed by the same chemicals. These plantations are unlikely to ever contribute to old growth resources since their investment clearcut is due to payoff at the age of 50 or maybe 80 years. Old growth forests are now the rarest habitats in the western united states.
