Palmyra Atoll – Ecosystem healing

(The post has been updated in 10. January 2023)

Palmyra Atoll or Palmyra Island is an atoll in the Central Pacific Ocean. It is part of Line islands (almost all belong to Kiribati except Palmyra and Kingman Reef, both belonging to the USA), and is the second northern island (only Kingman Reef is northern from Palmyra). Its size is about 2944 acres (1191 ha), and its maximum length/width is 6,9kmX2,3km. There are about 14 km of sea-facing reef and coastline. It is around 1600 km southwest of Honolulu.

Palmyra Atoll is an Incorporated territory of the United States Minor Outlying Islands, and is administrated by the United States Fish and Wildlife Service. It is also part of the Pacific Remote Islands Marine National Monument, a large marine protected area, actually, one of the world’s largest marine protected regions. The average height of the atolls is about 2m and the highest elevation is around 10m.

an amazing shite sandy beaches with bright blue colored waters and plenty of coconuts are there.

There is one boat passage and anchorage (from the south-western part of the atoll) that leads directly to the inner lagoon so that boats could anchor in the boat dock. That passage is artificially built for ships and submarines in WWII. Around 150 species of corals live in Palmyra’s waters, which is double more than in Hawaii. There are around 50 islets on the atoll, with the vast majority covered in dense vegetation.

there is plenty of vegetation on the atoll

The atoll is very beautiful and one of my favorites, the best. It has amazing white sandy beaches with nice shades of turquoise and blue warm water, too much vegetation (including many coconut palms as well), and great biodiversity. The atoll was discovered in 1798 by American Captain Edmund Fanning while traveling to Asia with his ship Betsy. It got its name from the ship Palmyra, which sunk on it on November 7. 1802.

those small ,,dots” are actually birds! Many seabirds live there.

In 1859. the island was annexed by the USA, and in 1862. by the Kingdom of Hawaii, and in 1898. after the annexation of Hawaii, it returned to USA possession. There is an airport at Palmyra Atoll, as well as some buildings and facilities for research and docks for boats. The atoll has a humid tropical climate, with an average temperature is about 29C year-round on the atoll, and average rainfall is around 4400mm per year. There are no permanent inhabitants.

The Nature Conservancy purchased Palmyra Atoll in 2000. to protect an endangered marine wilderness and establish a platform for applied conservation science. A major native rainforest restoration project is currently underway, and once finished, it should restore ecological balance to the atoll. They established Climate Adaptation and Resilience Laboratory at Palmyra Atoll for further research and actions to help the conservation of the atoll, as well as for better adapting and fighting locally (and globally indirectly) against the increasing effects of climate changes.

Now, you will see our very large gallery (165 pictures!), and you will get an ecosystem healing example that happened on Palmyra Atoll itself ( click on a picture and wait for a little until the gallery loads, then scroll left/right, and press Esc to exit, optionally you can press F11 for a bigger gallery).


Of course, there is also good news if one tries hard, that some places have been saved, and not only that, but they have made a significant contribution to the science of how to learn from their examples and what is achieved by their healing and how quickly. An example is the Palmyra Atoll directly.

This atoll was also heavily modified in World War II for war needs, an airport was built, bunkers, hangers were dug, reef and ground were pierced so that ships and submarines could pass. The Japanese attacked the atoll by water and by air, and even planes fell on it. Today is the best example of conservation of the environment, water and most contributes to science. The atoll was put under conservation, the state and conservation companies and UNESCO protected it. Tourism does not exist on it, rarely who with special permission can come. Only scientists and volunteers who maintain the island are there. In a short time, nature there healed itself. As soon as the rats were exterminated, everything went massively for the better. The birds returned, like many crabs, and began to breed much faster, as their rats were a dangerous threat. Not only that. The 2018 report stated that after the rat was exterminated, it was not long before the mosquito extermination! Neither rats nor mosquitoes are native to the island, they came here with the arrival of 2,400 soldiers in World War II, and have since terrorized the living world on the atoll. After the extermination of mosquitoes, which is a side effect of exterminating rats (because they mostly fed on rats and bird’s blood), birds, turtles, crabs and the rest of the world reproduce even faster. Experience with Palmyra has contributed most to science, as extinction of predators has a positive impact on mass ecosystem restoration. Of course, with as little presence as possible of people in the area. Also, reefs have been restored as much, because with the departure of human ships, pollution, rats and mosquitoes, the vast number of aquatic species as well as water quality has increased significantly. So they called that job “Paradise Renewed.”

That is why it is very important to preserve nature in such a way that the quality of the aquatic life, and therefore of the human being, can be improved very quickly, in order to reduce pollution, and to preserve the entire living world on which we depend.

It is important to note that about 4500 millimeters of rain per square meter falls on Palmyra annually, making it a region with heavy rainfall. At that point, the currents that bring southwest and northeast winds collide, creating bigger clouds and rain. Also, the Palmyra Lagoon is extremely deep for a smaller atoll, going below 30 meters deep, up to 50 meters deep, and the atoll has as many as three lagoons. With all this, lush vegetation, animals and corals make it unique of its kind.

This is why such research is of great importance for presenting and raising environmental awareness for the protection of water, oceans and islands, since without them there is no clean water. Through this kind of research, many environmental associations, scientists and organizations, via the media, try to impress people and raise awareness about environmental conservation.
