Temperate Forests within the United States are found in the Eastern region. Temperate forests can support a variety of species due to the large amount of rainfall. Mosses and lichens dominate the forest floor with medium-sized trees above such as dogwood trees. The top canopy is covered by larger trees such as maple trees, birch trees, and ...
Planting trees in tropical climates with wet seasons has another advantage. In such a setting, trees grow more quickly (fixing more carbon) because they can grow year-round. Trees in tropical climates have, on average, larger, brighter, and more abundant leaves than non-tropical climates.
Notable early examples of live plant harbored pests—such as beech scale, chestnut blight, and white pine blister rust—led to the Plant Quarantine Act of 1912 and regulations from the US Department of Agriculture in 1919. Despite these and subsequent regulations, insects and pathogens have continued to be introduced through live plants.
Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil. Code 330 defines standard methods recommended by the U.S. Natural Resources Conservation Service. Farmers have practiced soil ...
It shelters the soil from winds, which results in decreased wind erosion, as well as advantageous changes in microclimate. The roots of the plants bind the soil together, and interweave with other roots, forming a more solid mass that is less susceptible to both water and wind erosion. The removal of vegetation increases the rate of surface ...
Deforestation in Central America is one of the environmental problems that is linked to the settlement of agrarian frontier areas by land-seeking farmers and commercial agrarians, who facilitated the conversion of forest land to pasture, more expansion of cash crop like coffee, banana, logging activities, pasture and fuelwoods among other urbanization activities.

Team Trees was a 2019 fundraiser with an initiative to plant 20 million trees. The initiative was started by American YouTubers MrBeast and Mark Rober , and was mostly supported by YouTubers. The Arbor Day Foundation will work with its local partners around the world to plant one tree for each dollar they raise.
A soil borne pathogen is a disease-causing agent which lives both in soil and in a plant host, and which will tend to infect undiseased plants which are grown in that soil. [1] Common soil borne pathogens include Fusarium , [ 1 ] Pythium , [ 1 ] [ 2 ] Rhizoctonia , [ 1 ] Phytophthora , [ 1 ] Verticillium , [ 1 ] Rhizopus , [ 2 ] Thielaviopsis ...
