What? They are planting "genetic deserts" of hundreds of acres ofof industrial trees. Biodiversity is lost, habitat is lost because these are not the age, type and woodland mix of plants that made an aan actual habitat. Rows as far as the eye can see of lumber pine trees are no more of a proper habitat than mile after mile of cotton or rice or almonds in the CA central valleyvalley are a reasonable replacement for the habitat and biodiversity that was there previously, not to mention the critical loss of micro wetlands.

Biodiversity loss would be measured in loss of biodiversity, I would think.

yeah you'd think so. But that's not how it works. Ecologists estimate species loss by habitat loss. If a million-hectare forest contains a thousand species, and half of it is cut down, then 500 species are assumed to be lost.
