Yes.
They want the money too promote real trees over artificial ones.
The tried to do this on a voluntary basis, but could not get enough growers to chip in, so only the big growers paid.
Hence, they asked for this tax, to force little growers to pay into the kitty.
Of course, the little growers have no clout with the government, so this just ends up being a subsidy tax on little growers to support the goals of the big growers.
