An invasive species is an introduced species that harms its new environment. [2] Invasive species adversely affect habitats and bioregions , causing ecological, environmental, and/or economic damage.
This explains why areas in the United States such as Hawaii, Florida, and California are infested with invasive species. [3] These invasions are one of the biggest and most consistent threats to biodiversity across the globe. Antarctica is the only natural reserve on Earth that is without invasive species, due to its environmental factors. [2]
Specifically, biological pollution is the introduction of non-indigenous and invasive species, [1] otherwise known as Invasive Alien Species (IAS). When the biological pollution is introduced to an aquatic environment, it contributes to water pollution. Biopollution may cause adverse effects at several levels of biological organization:
A mature cotton thistle, an invasive weed in Australia.. A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is harmful to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock.
However, some plants grow a little too well. “Invasive plants spread aggressively and cause environmental changes, such as the elimination of native plant populations,” says Justine Kandra ...
Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, [2] introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation.
The problem with this approach is one, most invasive shrub species are not well controlled by run-of-the-mill pre-emergent herbicides, and two, there are no species-specific pre-emergents.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
