The coniferous forest is vast landscape of brown trunks and green pines. After the growth of the human population we can constantly see the decrease in the size of the coniferous forests by human factors such as logging and taking down the massive oaks to create space for more human accommo-dations.

However, there is also another major reason

to the decline of the coniferous forest pop-

ulations. The

trees that live

here are affect-

ed by an abiotic

factor known

as acid rain.

Acid rain is a

special type of precipitation

in which sulfur

dioxide and

compounds

of nitrogen mix

with water and

other substances in the atmosphere then rain down on the landscape. This is one of the biggest causes of recession in coniferous forests.

Most of the acid rain in Northern California is caused by humans burning fossil fuels and the releasing of carbon and other sulfides into the atmosphere. In the West Coast acid rain affects only higher altitude forests. When it precipitates acid rain the nutrients from the ground are drained by the rain and many of the nutrients are limited. Much of the acid rain is below the pH of 5.0 and will start to disintegrate tree bark if it does in contact with it.

Disintegrated tree bark is extremely useless and decomposers cannot retain any nutrients in it. This causes unbalance in the environment and this disruption eventually leads to a imbalance in the environment. This can cause serious amounts of damage to the food chain. Once many trees die the plants that take their place are limited to grow because of the acid rain in the soil. Now that the soil has been polluted with acid rain many plants are limited to nutrition. This causes lack of growth in many areas and the biome may completely change if acid rain continues to fall .

Scientists are very concerned about the continuance of acid rain. If acid rain’s pH does continue to decrease then not only will forests be affected, but also many humans will also be affected. The acid rain will eventually cause many human structures to wear

away and the sky will no longer be as blue as it was before. This is why scientists are trying to solve this problem before it is too late.
