In September 2019, the Plant-for-the-Planet app was released under an open-source license. It allowed users to register planted trees or to plant trees by donating to different tree-planting organizations around the world. [24] The foundation does not take any commissions for donations made through the campaign. [25]
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]
This initiative was planned to plant trees between 2006 and 2010 and the trees were expected to provide environmental benefits and were predicted to continue to grow until 2040. [4] This campaign is important and can increase urban woods as a piece of infrastructure that can assist cities in mitigating their environment. [ 5 ]
The cutting of trees was initiated on the island of Hispaniola and later other islands as well. Deforestation had an environmental impact with the expansion of sugar cultivation. Not only were trees felled and areas burned to create fields, but the woodlands beyond the fields were the source for wood for processing raw cane juice into refined ...
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.
Pre-existing natural communities remained largely intact south of the glaciers, but saw an increase in dominance of pine and a now-extinct species of temperate spruce, (Picea critchfieldii). This area included many plant communities that rely on a lightning-based fire regime, such as the longleaf pine woodland. When the glaciers began to ...

This is the largest giant sequoia (Sequoiadendron giganteum) among more than a dozen that were planted early in the 20th century in Laurelhurst Park of Portland, Oregon. The tallest tree in the world is the coast redwood; the most massive tree is the closely related giant sequoia. Both have non-overlapping native ranges limited to California ...
