For the 300 years following the arrival of Europeans, land was cleared, mostly for agriculture, at a rate that matched that of population growth. [7] During the 19th century, while the U.S. population tripled, the total area of cropland increased by over four times, from seventy-six million to three hundred nineteen million acres.
Map of wood-filled areas in the United States, circa 2000 [1]. In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2]
The island of Hispaniola was first colonized by humans 6,000 years ago and the population size was likely more than one million when the European colonists first arrived in 1492. [6] Those original inhabitants used trees and caused extinctions of birds and mammals. [11] [12] Nonetheless, the greatest deforestation occurred after 1492. [8]
Tornadoes of 2011, a series of destructive and record-breaking tornado outbreaks and tornado outbreak sequences strike the heartland of the United States, killing hundreds of people, injuring scores more, and causing billions of dollars in damages, particularly in St. Louis and Joplin in Missouri, Tuscaloosa and Birmingham in Alabama, and ...
The Dia Art Foundation maintain 37 trees paired with stones in New York City and consider this installation of 7000 Oaks one of their 12 locations and sites they manage. [7] In 2007 the artists Ackroyd & Harvey visited Kassel to collect acorns from the original oaks. 100 trees grown from these acorns were exhibited at Tate Modern in London, UK ...
A Quarter Century US Forest Disturbance History from Landsat – the NAFD-NEX Products. Eastern forests cover about 384 million acres (1,550,000 km 2) and are predominantly broadleaf (74%), with the exception of extensive coniferous forests and plantations in the southern coastal region. These are largely in private ownership (83%).
Two main opposing forces affect a tree's height; one pushes it upward while the other holds it down. By analyzing the interplay between these forces in coast redwoods (Sequoia sempervirens), a team of biologists led by George Koch of Northern Arizona University calculated the theoretical maximum tree height or the point at which opposing forces balance out and a tree stops growing.
The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth. Every year, 75,700 square kilometers (18.7 million acres) of the forest is lost. [14] There was a 12% increase in the loss of primary tropical forests from 2019 to 2020. [15]
