Unlike most ecosystems, in serpentine barrens, there is less plant growth closer to a stream, due to toxic minerals in the water. Serpentine barrens are a unique ecoregion found in parts of the United States in small but widely distributed areas of the Appalachian Mountains and the Coast Ranges of California, Oregon, and Washington.

Soils derived from serpentine are toxic to many plants, because of high levels of nickel, chromium, and cobalt; growth of many plants is also inhibited by low levels of potassium and phosphorus and a low ratio of calcium/magnesium. The flora is generally very distinctive, with specialized, slow-growing species.
However, because serpentinite outcrops are few and isolated, their plant communities are ecological islands and these distinctive species are often highly endangered. [21] On the other hand, plant communities adapted to living on the serpentine outcrops of New Caledonia resist displacement by introduced species that are poorly adapted to this ...
Noxious weeds can be deadly for humans, animals and other plants in your garden. Here’s how to identify a plants before you get hurt. You may have poison in your garden.
Symphyotrichum depauperatum (formerly Aster depauperatus), commonly known as serpentine aster or starved aster, [4] [5] is a rare species in the family Asteraceae adapted to serpentine barrens, an ecosystem with a high concentration of toxic metals in the soil.
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
Make sure you know what these plants look like and where you can find them. This guide includes common plants that are toxic to the touch and to eat. A guide to some of NC’s most dangerous ...
Pesticide poisoning is an important occupational health issue because pesticides are used in a large number of industries, which puts many different categories of workers at risk. Extensive use puts agricultural workers in particular at increased risk for pesticide illnesses.
