Dried up land in a drought

This page is about droughts and their effects on the ecosystem.

What are droughts?Edit

A drought is a prolonged period of abnormally low rain, with a shortage of water resulting from this. A drought is caused by a depletion of precipitation over time.


Impacts on EcosystemsEdit

Droughts damage the environment in many different ways - like depleting food and water sources, causing diseases, and also lowering soil quality. In a drought, due to the lack of water, wetlands dry up and the water level of reservoirs lakes and ponds also goes down - destroying habitats for marine life. Plants will dry up, leading to a lack of food for animals, an increase in diseases in wild animals and even higher risks in wildfires! The soil will also dry up and become a target for wind and water erosion - causing increased desertification and possibly a dust bowl.







AnimalsEdit

Dead animals

Droughts are very nasty for animals - especially endangered ones, because they can cause increased stress on the population and even extinction! There would be much habitat loss and an increase in predation because of the lack of food. Many animals are forced to leave the area of the drought to search for a better place to live.



PlantsEdit

Dead Plants

Water will dry up in a drought, and so will plants. Plants can die from the lack of water, and the ones that survive are vulnerable to a higher risk of wildfire.  Because plants keep soil from eroding, the disapearence of plants in a drought can also cause more soil erosion.
