Tree planting is the process of transplanting tree seedlings, generally for forestry, land reclamation, or landscaping purposes. It differs from the transplantation of larger trees in arboriculture and from the lower-cost but slower and less reliable distribution of tree seeds .
The project called for large-scale planting of trees across the Great Plains, stretching in a 100-mile wide zone from Canada to northern Texas, to protect the land from wind erosion. Native trees, such as red cedar and green ash, were planted along fence rows separating properties, and farmers were paid to plant and cultivate them. The project ...

The first Christmas tree farm was established in 1901, but most consumers continued to obtain their trees from forests until the 1930s and 1940s.
It has been shown that they are beneficial to humans in creating a sense of well-being and reducing stress. Many towns have initiated tree-planting programmes. [150] In London for example, there is an initiative to plant 20,000 new street trees and to have an increase in tree cover of 5% by 2025, equivalent to one tree for every resident. [151]
The dominant tree groups today are all seed plants, the gymnosperms, which include the coniferous trees, and the angiosperms, which contain all fruiting and flowering trees. No free-sporing trees like Archaeopteris exist in the extant flora. It was long thought that the angiosperms arose from within the gymnosperms, but recent molecular ...
A tree defect is any feature, condition, or deformity of a tree that indicates weak structure or instability that could contribute to tree failure. Common types of tree defects: Codominant stems: two or more stems that grow upward from a single point of origin and compete with one another. common with decurrent growth habits
Earth offers enough room to plant an additional 0.9 billion ha of tree canopy cover. [4] Planting and protecting them would sequester 205 billion tons of carbon [4] which is about 20 years of current global carbon emissions. [5] This level of sequestration would represent about 25% of the atmosphere's current carbon pool. [4]
The arboretum is the realization of the dream of William Douglas Cook (1884–1967), who started planting trees on his farm shortly after the First World War. The arboretum is now the National Arboretum of New Zealand, and holds some 4,000 different trees, shrubs and climbers. Taitua Arboretum, Hamilton, New Zealand
