A good post. My only real comment is that small woodland owners often plant
at twice that density. Here in Douglas County, a seedling density of
750 trees per acre is not uncommon. Planting density like that absolutely
requires early thinning, but you get much higher early fiber production,
an early closed canopy to suppress brush, and less lower limb growth,
leading to better log grade. The biggest reason is that you can always
pull a few trees out, but bare land isn't making you any money.

With that poundage, I think the original poster might have been talking
about hybrid poplar plantations. I don't know what density they plant,
since I don't grow poplar, but it's dense. I would GUESS a couple
thousand trees per acre? Maybe somebody actually in pulp production
could give some hard numbers.
