TIL forrest growth in the US has exceeded harvest since the 1940’s, and that today we have more trees than any time in the past 100 years.(r/todayilearned)
I’m betting a lot of those old growth forests that they list in 1620 were about 100-130 years old. Why? Because that’s when the forests ceased being managed due to the unfortunate demise of 90+% of the original inhabitants. If you want to know more about how Native Americans managed the continent (both forest and grasslands) read Charles Mann’s book 1491. He hypothesizes that many of the thing we think of when we think about ‘wilderness’ in North America (thick forests, huge herds of bison and flocks of passenger pigeons etc) are actually a result of the die-off of a continent’s worth of people who kept those populations in check and resulted in giant population explosions of animals and overgrown forests.
