When heavy machinery is used to clear forests or develop land, the soil becomes compacted. When the soil is compacted, the soil particles are packed tightly together. Soil compaction results in water supply not being absorbed by tree roots and can be deadly to the growth of trees. Soil compaction also can create flooding.
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. [1]
A relatively small amount of rainfall coupled with the slow decomposition of organic material allows the acidic plant debris to sit and saturate the top horizons of the soil profile. As a result of the infertile soil, only a few plant species can really thrive in the taiga. The common plant species in the taiga are coniferous trees.
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.
Third, the deforestation of tropical forests is leading to land degradation. When forests are cleared, the soil is often left exposed to erosion. This can lead to land degradation, which can make it difficult to grow crops. The deforestation of tropical forests for fruit production is a serious problem with a number of negative environmental ...
Non-native plants can escape and spread across fields, gardens and waterways, potentially becoming invasive throughout the Buckeye State. 'They do cause problems': Dangers of releasing invasive ...
Many plant and animal species became extinct in North America soon after first human arrival, including the North American megafauna; others have become nearly extinct since European settlement, among them the American bison and California condor. [29] The last of the passenger pigeons died in 1914 after being the most common bird in North ...
