There are 2.8* times more people in U.S. than 100 years ago. * http://www.mnforsustain.org/united_states_population_growth_graph.htm http://www.mnforsustain.org/united_states_population_growth_...

  Which makes the vast tree recovery even more impressive.

  That link is horrible. They state that the population is (in millions), when it's actually in thousands. And they can't be bothered to include the actual 2010 census.

This is suprising but now compare this to rainforest devastation in the Amazon and the rest of the world and I doubt we're in the positive overall which is what logically counts.

> The average age of forests in the United States is younger than it was before European settlement. The greatest diversity is found in the oldest forests, so there may be more forest now, but because it is so young, it is home for fewer animals, plants, insects and other organisms than a fully developed, mature forest ecosystem. It also means that protecting old growth forests is imperative. https://www.google.com/maps/place/Oregon,+USA/@43.8637703,-122.4869927,1579m/data=!3m1!1e3!4m2!3m1!1s0x54936e7c9b9f6a55:0x7d4c65db7a0bb876 https://www.google.com/maps/place/Oregon,+USA/@43.8637703,-1... - you can see that there are more trees in the more recently clear cut sections, and fewer in the older growth.

This is also true in Germany and probably most other European countries, use of timber for energy production and for mining and building purposes led to devastated areas in Central Europe during the 16th to 18th centuries, this was only reversed during the 19th century when coal and steel took over, and the introduction of sustainable foresting. Since then forests are growing again, with a few dips like after WW2.

> "The greatest gains have been seen on the East Coast (with average volumes of wood per acre almost doubling since the '50s) which was the area most heavily logged by European settlers beginning in the 1600s, soon after their arrival." I believe another reason is that the introduction of the railway shifted food production to the plains and California. New England used to be farmland for much of the US. See http://www.bostonglobe.com/metro/2013/08/31/new-england-sees-return-forests-and-wildlife/lJRxacvGcHeQDmtZt09WvN/story.html http://www.bostonglobe.com/metro/2013/08/31/new-england-sees... : > Today, 80 percent of New England is covered by forest or thick woods. That is a far cry from the mere 30 to 40 percent that remained forested in most parts of the region in the mid-1800s, after early waves of settlers got done with their vast logging, farming, and leveling operations. > Some of the revival can be credited to aggressive environmental efforts ... But the return of forests has mostly been a matter of economics: As New England became more citified and industrial, and food from western states became cheaper, there was less reason to maintain open land — much less blast every wild critter that might nibble a crop or gobble a goose.

The number of trees increased, but the volume of wood decreased. Also of note, older trees take up more space so land area is a better measure than tree count.

  At the same time, turning young trees into old trees isn't a very difficult problem. Once the decision is made either by economics--farming is no longer viable--or aesthetics to let the trees grow back, it's only a matter of time.

    "farming is no longer viable" In the plain states, large rows of tree were planted for farming (e.g. shelter belts). Many places trees exist today did not have trees pre-farming. This was the great plains, not a forest region. If farming is no longer viable then humans are no longer viable.
    - claystu 11y ago
      I wasn't saying that farming is no longer viable anywhere as a business. I was saying that there are places, like my home state, that have seen a resurgence of forest as farms have disappeared due to competition from elsewhere.

Wood was mostly used for fuel back then. The turn of the 20th century also marked the end of the sailship era and the end of wood as a major element in ship construction. Other uses for wood were sleepers for railways and whole logs for utility poles. Incidentally, US aircraft carriers had wooden decks in WW2 and wood was still an element in airplane construction. In the last few decades chipboard furniture and managed tree farms further reduced deforestation. Keep in mind that the conditions US colonists found in the US: a massive, dense, virgin forest were not natural. The massive depopulation of native peoples allowed forests to grow thick and create the illusion of an uninhabited land. Normally people manage the land, usually unintentionally from just living on it.

North Carolina--East Coast state in USA--is basically contiguous forest once you leave the downtown area of our few big cities. Farms and neighborhoods still punctuate the landscape, but any land that isn't routinely maintained by farming and mowing begins to revert back to woods very quickly.

  My guess also, looking at the number of farms-turned-to-subdivisions, parks and green areas along the East Coast, is that better logistics and transport has further improved the efficiency of distributing goods from megafarms in the midwest, making the need for smaller and less efficient traditional colonial-era farms obsolete. At the same time, the midwest, especially the great plains area, were always tree sparse.

A vastly larger proportion of land was utilized a hundred years ago for agriculture. I've seen photographs from the 1910s of my hometown which are unrecognizable, except for the buildings, because most of the portions of the hillsides and river intervale pieces were cleared and used for growing either corn or grazing sheep and cattle. Now all of that area has grown up into forest.
