The trees in these forests do not grow as quickly as usual. Leaves and needles turn brown and fall off when they should be green and healthy. Researchers suspect that acid rain may cause the slower growth of these forests. But acid rain is not the only cause of such conditions. Other air pollutants, insects, diseases and drought are some other causes that harm plants. Also, some areas that receive acid rain show a lot of damage, while other areas that receive about the same amount of acid rain do not appear to be harmed at all. However, after many years of collecting information on the chemistry and biology of forests, researchers are beginning to understand how acid rain works on the forest soil, trees, and other plants. Acid Rain on the Forest Floor A spring shower in the forest washes leaves and falls through the trees to the forest floor below. Some of the water soaks into the soil. Some trickles over the ground and runs into a stream, river or lake. That soil may neutralize some or all of the acidity of the acid rainwater. This ability of the soil to resist some pH change is called buffering capacity. A buffer resists changes in pH. Without buffering capacity, soil pH would change rapidly. Midwestern states like Nebraska and Indiana have soils that are well buffered. Places in the mountainous northeast, like New York's Adirondack Mountains, have soils that are less able to buffer acids. Since there are many natural sources of acid in forest soils, soils in these areas are more susceptible to effects from acid rain.

Acid rain From the Simple English Wikipedia, the free encyclopedia that anyone can change Jump to: navigation search Acid rain is where chemicals in the air combine with rain and make the water more acidic Normally, the pH of rain is about 6.5, which means it is a weak acid. Other chemicals can make this a stronger acid if they react with it. When this rain falls to the ground, it can kill fish in the rivers, harm plants, and dissolve building materials. This is why many gravestones are unreadable. The most common chemicals which do this are oxides of sulphur and nitrogen , which are put into the air by power stations and vehicles (such as cars). There are also some natural causes, like volcanoes and biological processes that happen on the land, in wetlands, and in the oceans Many countries are trying to reduce the amount of acid rain by agreeing to treaties , and by taking part in emissions trading . In the United States , many power stations use a process called Flue gas desulphurization (FGD) to reduce the sulphur in the gases that are made. Acid rain can make forests grow slower, or even destroy them. This affects animals and their
