Jarvis Island is a small place. 

Jarvis Island is a small coral island. 

The island is very hot and sunny. It is also very dry. There is not much rain there. The ground is mostly sand.
A big hole sits in the middle. This hole is a dry lagoon. Long ago, people dug for bird droppings there. They used it to help plants grow.
Many birds live on the island now. They use the land to rest and find food. Some birds are coming back to the island. 
Today, the island is a safe place. It is a home for many animals.
Jarvis Island is a small coral island. 
The island is very hot and sunny. It is also very dry. There is not much rain. The ground is mostly sand. There are no big plants. Only small shrubs and vines grow there. The middle of the island has a dry lagoon. This is a large, low area.
Long ago, people came to dig for guano. Guano is bird droppings. People used it as fertilizer to help plants grow. They used tracks to move the guano. 
Today, the island is a nature refuge. No people live there now. It is a safe home for many birds. Many seabirds come to the island to rest and find food. 
Jarvis Island is a small coral island in the South Pacific Ocean. 
The island has a very dry, tropical desert climate. It is often hot with intense sun and constant wind. However, the nights can be quite cool. There is very little rainfall on the island. Because of this, there is no known natural source of fresh water. 
People have used the island for many different reasons. In the 19th century, people came to mine guano. Guano is bird droppings that people used as fertilizer. They built a two-story house and laid down tram tracks. 

Jarvis Island is now a safe home for many animals. 

Even though no one lives there now, the island is still busy. It is managed by the U.S. Fish and Wildlife Service. This helps protect the plants and animals from harm. The island is a quiet place where nature can thrive. It is a very different world from the crowded cities we know. Scientists and visitors come to learn about this remote part of the ocean. It remains a vital stop for birds traveling across the sea.
Jarvis Island is an uninhabited coral island located in the South Pacific Ocean. 
The island's physical structure is shaped by ancient geological processes. Roughly 125,000 years ago, during the latest interglacial period, the island was submerged. This happened because sea levels were higher than they are today. As sea levels eventually declined, a horseshoe-shaped lagoon formed in the center. Unlike most coral atolls, the lagoon on Jarvis is completely dry. The island is low-lying and surrounded by a narrow fringing reef. It is often difficult for small ships to sight the island from the sea.
The environment on Jarvis Island is a tropical desert. This means the climate is characterized by high daytime temperatures and intense sun. There is also constant wind, though nights can become quite cool. Rainfall is very scarce on the island. Because of this lack of rain, there is no known natural freshwater lens. A freshwater lens is a layer of drinkable groundwater that sits under an island. Because the island is small and arid, visitors must carry potable water in containers. This harsh climate creates a flat landscape with very little vegetation. Only low-growing shrubs, prostrate vines, and sparse bunch grass can survive here.
Human history on the island began with the extraction of guano. Guano is a material made of accumulated bird droppings. In the 19th century, it was highly valued as a fertilizer. The United States claimed the island in the 1850s under the Guano Islands Act. For about 20 years, companies mined the deep guano deposits in the central lagoon. They built a two-story superintendent's house and laid down tram tracks to move the material. 
In the 20th century, the island saw a brief period of settlement. Under the American Equatorial Islands Colonization Project, a settlement called Millersville was established in 1935. 

Modern Jarvis Island is primarily a site for scientific study and nature conservation. During the International Geophysical Year from 1957 to 1958, scientists visited the island. A severe storm in January 1958 swept away many of the remaining nineteenth-century ruins. In 1974, the government created the Jarvis Island National Wildlife Refuge. This refuge was expanded in 2009 to include submerged lands. The refuge now covers a vast area of both land and water. 
The island is an Important Bird Area (IBA) recognized by BirdLife International. It serves as a vital nesting and foraging habitat for many species. These include lesser frigatebirds, masked boobies, and sooty terns. While guano mining and introduced rodents once harmed the wildlife, some species are recovering. For example, the population of brown noddies grew to nearly 10,000 by 2004. The Polynesian storm petrel also returned to the island after a 40-year absence. The surrounding waters are also rich with life, such as the grey reef shark.
