The reasons they are endangered include habitat destruction, human disturbance, livestock grazing, disease, predation and construction for trams, trails and roads. Located in the Salton Sink basin of the Imperial Valley in southeastern California, desert pupfish typically live in springs, slow-moving streams and seeps near the Salton Sea. With a life span of from one to three years, the desert pupfish is a small fish no more than 3 inches long.
Breeding in March through late September, female pupfish lay about 50 to eggs. They can live in water temperatures up to degrees Fahrenheit, but with the introduction of non-native predatory species, desert pupfish were added to the endangered species list in Natural populations of this desert fish occur in shoreline pools near the Salton Sea, irrigation drains, freshwater ponds, and creeks and washes that feed into the Salton Sea.
Endangered Species Act allows for the institution of recovery plans to help an endangered or threatened species to recover and thrive. Scientists, biologists and other animal specialists create plans that include site-specific actions necessary for species recovery, such as habitat protections, measurable criteria that help determine results, and a budget and timeline for the species recovery. Because of such recovery plans, the American bald eagle was removed from the threatened and endangered species list in As a journalist and editor for several years, Laurie Brenner has covered many topics in her writings, but science is one of her first loves.
Her stint as Manager of the California State Mining and Mineral Museum in California's gold country served to deepen her interest in science which she now fulfills by writing for online science websites. In some cases, the balance of life is so fragile that one unusually dry or wet season can lead to massive changes.
This environmental sensitivity means that deserts face many threats, both from human activity as well as from natural climate cycles. Natural weather variability can drastically alter the temperatures and amount of rainfall of any given region.
For example, an El Nino pattern in the Pacific can lead to wet winters, bringing lots of rainfall to the deserts of the South American continent. La Nina, on the other hand, tends to bring drought during the same period. As these patterns become extreme or repeat themselves multiple years in a row, the changes to normal rainfall patterns can cause a disruption in the ecosystem of the desert, reducing the number of plants and animals able to thrive away from permanent water sources.
While its watery habitat has been drastically reduced by drought, groundwater contamination and pumping for agricultural use, it's also threatened by the North American mosquito fish Gambusia holbrooki. Due to changing environmental conditions, this ice has been thawing at alarming levels. The reasons they are endangered include habitat destruction, human disturbance, livestock grazing, disease, predation and construction for trams, trails and roads.

List of Endangered Animals of the Desert.
Climate change affects the desert just as it affects every other biome. Deserts around the world have been warming at a rate of 0.
A rise in desert temperatures can dry out plants, making them more vulnerable to wildfires, or they might simply die due to a lack of moisture. Likewise, the animals that make the desert their home may not be able to cope with the increased temperatures, limiting their range or forcing them to migrate to cooler regions.
During the 20th century, much of the Sahel region adjacent to the Sahara desert suffered desertification, greatly changing the makeup of plant and animal life in the area. However, this has changed with time. There are few sightings of the wood bison, and the only wild herds left are located at the Alaska Wildlife Conservation Centre.
However, there have been concerted efforts to reintroduce wood bison back to their habitat. The caribou is an endangered species due to increased threats from oil and gas mining projects in the Tundra region, leading to loss of habitat, in part due to forest logging.
Just like other marine animals see this article on Largest Groups of Coral Reef in the World , these whales are feared to be declining due to the increased threat from over hunting and climate change. They are hunted because their skin provides the much-needed vitamin C that the people in the Arctic regions need. Some have also been hunted because of their ivory tusks.
At one point, there existed only musk oxen in the world. This was largely due to over hunting. However, their numbers have increased, and there are close to 40, species today. These whales are at greater risks of extinction due to increased fossil fuel extraction activities in the Arctic region. As of , the documented number of beluga whales was at This has prompted relevant authorities to list it as an endangered species.
