Three Trillion Trees?
There are roughly 3 trillion trees on Earth — more than seven times the number previously estimated, according to a tally by an international team of scientists.

It'd be just as interesting to look at the change in standing biomass. I bet it's down a lot more than half.

Exactly! And, did they count seedlings as trees? The number of trees isn't what counts- it's as you say, the forest biomass.

The forestry propagandists in America love to say, "there are more trees growing now than when the Europeans arrived"- maybe, and most are tiny- the biomass of America's forests is probably 10% of what it was, or less.

If you clearcut a forest in the East, you might get 10,000 seedlings come in within a few years.

And, I bet the error bar on that 3 trillion is huge. Here in Mass., our forestry "leaders" said, a few years ago, the condition of the forests of the state based on 1 "prism plot" for every 6,000 acres! And, they gave the statistics to several decimal places. When I pointed out the absurdity of that- they just couldn't understand why their figures were not accurate to several decimal places! And it's these lame brains that set forestry policies!
