Human Impact on Mono Lake Tufa State Reserve


Back in 1863, Europeans came to the ecosystem known as Mono Lake and created towns in north Mono. By creating these towns, people obviously needed food, so commonly they would hunt. That created a problem for animals living there because once the humans started hunting, the animal poplulation decreased. When that happened, the animals started to die because of food deprivation and the prey of the animals that died increased because there were no predators.

When the Europeans started to build houses for the community, they used lumber from the trees in the nearby forest, which is the Pinon Pine Forest. This destroyed the whole pine forest and also created problems for the animals that lived there because their habitats were destroyed. When the Europeans moved to the area, they destroyed the habitat of the organisms living there. When the habitats were destroyed, a lot of animals died and then when predetors of those animals needed food, and there was non, they died of food deprivation.


These are some of the homes that the Europeans lived in. (modern day picture)

In 1941, Los Angeles began diverting water from the freshwater streams that feed Mono Lake. Aquaducts carried the water 563 kilometers (352 miles) to a rapidly growing city. Changes to the lake were dramatic. Without a freshwater source, the salinity of the lake doubled. By 1995 the water level dropped over 13.7 meters (45 feet).
