Palmyra Atoll ( //) is one of the Northern Line Islands (southeast of Kingman Reef and north of Kiribati Line Islands), located almost due south of the Hawaiian Islands, roughly one-third of the way between Hawaii and American Samoa. The nearest continent is almost 3,355 miles (5,399 kilometers) to the northeast. The atoll is 4.6 sq mi (12 km2), and it is located in the equatorial Northern Pacific Ocean. Its 9 mi (14 km) of coastline has one anchorage known as West Lagoon.
It is the northernmost of the Line Islands, and one of four American islands in the archipelago, along with Jarvis Island, Johnston Atoll and Kingman Reef. Palmyra Atoll is part of the Pacific Remote Islands Marine National Monument which makes up the largest marine protected area in the world. The atoll is made up of submerged sand flats along with dry land and reefs. It consists of three lagoons separated by arms of coral reefs. The Western Reef terrace is one of the biggest shelf-reefs, with dimensions of two by three miles. Over 150 species of coral have been recorded at Palmyra Atoll, double the amount of species recorded in Hawaii. 
Palmyra Atoll is an unoccupied equatorial Northern Pacific atoll administered as an unorganized incorporated territory, the only one of its kind, by the United States federal government. The 4.6-square-mile (12 km2) territory hosts a variable temporary population of 4–25 "non-occupants", namely staff and scientists employed by various departments of the U.S. government and by The Nature Conservancy,  as well as a rotating mix of Palmyra Atoll Research Consortium  scholars pursuing research. Portions of the atoll are administered by the Department of the Interior's Office of Insular Affairs.  Palmyra Atoll is one of the islands in the U.S. Minor Outlying Islands.
The islets of the atoll are mostly connected. Sand Island and the two Home Islets in the west and Barren Island in the east are not. The largest island is Cooper Island in the north, followed by Kaula Island in the south. The northern arch of islets is formed by Strawn Island, Cooper Island (or Cooper-Meng Island since former Cooper and Meng Islands were joined in 1940), Aviation Island, Quail Island, Whippoorwill Island, followed in the east by Eastern Island, Papala Island and Pelican Island, and in the south by Bird Island, Holei Island, Engineer Island, Tanager Island, Marine Island, Kaula Island, Paradise Island, the Home Islets and Sand Island (clockwise).
In The Insular Cases, the Supreme Court held incorporated territories to be integral parts of the United States, as opposed to unincorporated territories being merely possessions. The incorporated United States Territory of Palmyra Island has the southernmost point of the incorporated United States of America, with its southernmost shore at 5°52'15" N latitude. U.S.-controlled territories such as American Samoa (and the southernmost place, Rose Atoll) are farther south, but they are not incorporated territories of the country.  
Average annual rainfall is approximately 175 in (4,400 mm) per year. Temperatures average 85 °F (29 °C) year round. The atoll has the highest oceanicity index[ clarification needed] and lowest diurnal and annual temperature variation of any place on earth.[ citation needed]
Although Palmyra is a coral atoll with several islets, not a single island, it has been called Palmyra Island since the first visit in 1802.  More recently it is for some purposes called Palmyra Atoll. The name of the federal territory retained by Congress since 1959 is Palmyra Island,  but the official name of the National Wildlife Refuge within the territory is Palmyra Atoll, as is the corresponding division of the Pacific Remote Islands Marine National Monument.  The formal deeds, leases and federal orders for land there call it Palmyra Island.  Further, the islets on the atoll are also named Island, such as Kaula Island, Cooper Island, etc. 
Palmyra is an incorporated territory of the United States (the only such territory since 1959), meaning that it is subject to all provisions of the U.S. Constitution and is permanently under American sovereignty. However, since Palmyra is also an unorganized territory, there is no Act of Congress specifying how Palmyra should be governed. Palmyra has no permanent residents; however, in 2004 accommodations were built to support a small number of temporary inhabitants.
The only relevant federal law simply gives the president the authority to administer Palmyra as directed, or via the United States District Court for the District of Hawaii (Hawaii Omnibus Act, Pub. L. 86–624, July 12, 1960, 74 Stat. 411). 
The issue of the governing of Palmyra is generally a moot point since there is no permanent population remaining there, nor any reason to think that there will be in the near future. Cooper Island and ten other land parcels in this atoll are owned by The Nature Conservancy, Inc., which manages them as a nature reserve. The southwesternmost islets, including Home, are owned by descendants of former Palmyra owner Henry Ernest Cooper and others. The rest of Palmyra is federal land and waters under the jurisdiction of the U.S. Fish and Wildlife Service.  Since Palmyra has no state or local government, it is administered directly from Honolulu by the U.S. Fish and Wildlife Service, except for some submerged tracts administered by the Office of Insular Affairs, both in the U.S. Department of the Interior. For all other purposes, Palmyra is counted as one of the U.S. Minor Outlying Islands. They are outside of the customs territory of the United States and have no customs duties.  
Palmyra land was registered in Hawaii Land Court in 1912.  In 1959, the rest of the federal Territory of Hawaii, excluding Palmyra and the Stewart Islands (now known as Sikaiana), became the state of Hawaii. Hawaii Land Court became a state court and lost jurisdiction over Palmyra land. Instead, Palmyra land documents are filed or recorded in federal court in Honolulu. 
Palmyra Atoll was part of the Kingdom of Hawaii, and because of this, the Hawaiian sovereignty movement considers Palmyra Atoll to be under illegal U.S. occupation along with the rest of Hawaii.   At the overthrow of the Kingdom, the land belonged to F. W. Wundenberg, William Hope, Kauhaikane and William Ringer; under Kingdom law, their heirs would own Palmyra now rather than the current landholders.  
There is no current economic activity on Palmyra other than paid ecotourism visits and sport fishing by Nature Conservancy donors. Most of the roads and causeways there were built during World War II. All of these are now unserviceable and overgrown with bushes and grass, and most have washed-away gaps. There is a 2,000-yard (1,800 m)-long unpaved airstrip on Cooper Island ( Palmyra (Cooper) Airport, ICAO code PLPA) that was built for the Palmyra Island Naval Air Station before and during World War II.
A construction program in 2004 erected several two-person bungalows and showers for the temporary residents. Fresh water is collected from the roof of a concrete building in this area. The communal buildings of the area on the southwestern coast of Cooper Island (the only occupied area of the atoll) consist of about half a dozen buildings next to the only sea dock.[ citation needed]
Palmyra was first sighted in 1798 by captain Edmund Fanning of Stonington, Connecticut, master of the American sealing ship Betsy, on a voyage to Asia, according to his published memoir 35 years later.  Fanning wrote that he had awakened three times during the night before, and after the third time took it as a premonition, ordering Betsy to heave to for the rest of the night. The next morning, Betsy resumed sailing, but only about a nautical mile further on, and he believed that he sighted the reef later known as Palmyra Island. Had the ship continued on her course at night, the ship might have been wrecked.  Captain Fanning's claim to have discovered Palmyra itself has been challenged, on the view that he had only reached Kingman Reef 34 miles (55 kilometers) away and could not possibly have seen Palmyra from that distance.  On page 3, the Baltimore newspaper The Telegraphe and Daily Advertiser of July 29, 1803 appears to quote directly from Edmund Fanning’s journal with: "We supposed that we saw land from the masthead to the southward of the shoal ( Kingman Reef) but it was so hazy we were not certain." This would stand in sheer conflict with Fanning's book of 1833, in which he, while referring to Kingman Reef, wrote “I went aloft, and with the aid of the glass could plainly see the land over it, far in the south.” 
On November 7, 1802, the ship Palmyra, under Captain Cornelius Sowle, was shipwrecked on the reef, which was given the name of this vessel.  The remote atoll, lacking a navigable boat passage through the reef from the sea, had never been inhabited. No marae, basalt artifacts or evidence of Polynesian, Micronesian or other pre-European native settlements before 1802 have been found on Palmyra. Captain Sawle wrote:
There are no inhabitants on the island, nor was any fresh water found; but cocoanuts [ sic] of a very large size, are in great abundance; and fish of various kinds and in large shoals surround the land.  
During the 19th and 20th centuries, stories circulated in the Pacific of a large treasure of gold, silver and precious stones (sometimes described as Inca treasures) that had been looted in the Viceroyalty of Peru.  A crew loaded it in secret onto the ship Esperanza in Callao harbor, Peru, and embarked into the Pacific Ocean on January 1, 1816, bound for the Spanish West Indies.
According to a survivor, seaman James Hines, the Esperanza was caught in a storm which dismasted and damaged the ship. Thus crippled, it was attacked and boarded by pirates, who loaded the treasure and surviving crew onto their own ship. The Esperanza sank, and they sailed west across the Pacific bound for Macao.
After 43 days, the pirates' ship met a storm, lost course, and struck hard the coral reef surrounding Palmyra Island, breaking the mast. The ninety men aboard were able to pull the ship in closer to land but it was not serviceable. They offloaded the treasure to the island, distributed some, and buried the rest. They repaired part of their boat and most of the crew shipped away. They were not heard from again. The remaining ten men spent most of a year on Palmyra living off of dwindling stores and local food. They spent three months building a small escape boat, and six men left Palmyra on the boat. Of these, four were washed overboard in a storm and the other two were rescued by an American whaler bound for San Francisco. One died en route, and the survivor, James Hines, was put in a hospital; 30 days later he died.
Before he died, he wrote letters describing the affair and the location of the treasure, which originally included 1.5 million Spanish pesos of gold and an equal value in silver (possibly consisting of precolumbian artworks). In around 1903, over 95 years later, the letters were allegedly deposited for safekeeping with Capt. William R. Foster, the harbormaster of Honolulu, by a sailor who was bound for the Solomon Islands but never returned. After holding the letters for 20 years in an iron chest, Capt. Foster revealed them to a reporter who published the details.  Palmyra landowner Henry E. Cooper was reported to have researched the matter. A conflicting variant of the story was published by Capt. F. D. Walker of Honolulu in 1903  and in 1914.  In 1997, William A. Warren filed a federal salvage claim for a ship sunk off the atoll which he claimed had treasure from the Esperanza, but he abandoned his claim after legal objection from the Fullard-Leos, who owned most of Palmyra. 
The legend of the Esperanza and Santa Rosa (a ship rumored to have recovered the Esperanza treasure and sailed back to Honolulu), inspired a story written by Jack London, called "The Proud Goat of Aloysius Pankburn", which was published as part of London's David Grief stories in the Saturday Evening Post.  
The Esperanza treasure figures in a 2010 work of fiction, Palmyra – Isle of Death by Karl Boyd. 
The atoll was visited by the USS Porpoise in 1842 as part of the United States Exploring Expedition, with the expedition's leader Charles Wilkes on board. This marked the first visit to Palmyra of a scientific expedition, and various live samples were collected of the native plants and animals. In his 23rd volume recording the findings of the USXX, Wilkes wrote of Palmyra:
This island is inhabited...It is to be regretted that all these detached islands should not be visited by our national vessels, and friendly intercourse kept up with them. The benefit and assistance that any shipwrecked mariners might derive from their rude inhabitants, would repay the time, trouble, and expense such visits would occasion. 
On February 26, 1862, King Kamehameha IV of Hawaii commissioned Captain Zenas Bent and Johnson Beswick Wilkinson, both Hawaiian citizens, to take possession of the atoll. On April 15, 1862, it was formally annexed to the Kingdom of Hawaii, while Bent and Wilkinson became joint owners. 
Over the next century, ownership of the atoll passed through various hands. Bent sold his rights to Palmyra to Wilkinson on December 25, 1862. Palmyra later passed to Kalama Wilkinson (Johnson's widow). In 1885, it was then divided among her four heirs,  two of whom immediately sold their rights to William Luther Wilcox who, in turn, sold them to the Pacific Navigation Company. In 1897, this company was liquidated, and its interests were sold first to William Ansel Kinney, and then to Fred Wundenberg, all of Honolulu.  On June 12, 1911, Wundenberg's widow sold his two-thirds undivided interest in Palmyra as a tenant in common to Judge Henry Ernest Cooper (1857–1929). 
In 1898, the United States by the Newlands Resolution annexed the Republic of Hawaii, formerly the Polynesian Kingdom of Hawaii, and Palmyra with it. An Act of Congress made all of Hawaii, including Palmyra, into an "incorporated territory" of the United States at that time. (Act of April 30, 1900, ch. 339, §§ 4–5.) On June 14, 1900, Palmyra became part of the new U.S. Territory of Hawaii.  To end all British claims, Congress passed a second act of annexation in 1911.[ citation needed]
With imminent opening of the Panama Canal, Palmyra became strategically important. Britain had established a submarine cable station for the All Red Line on nearby Fanning Island.  So the U.S. Navy sent USS West Virginia to Palmyra, where on February 21, 1912, American sovereignty was formally reaffirmed. 
William Ringer, Sr. died in 1909 survived by his wife and three minor daughters. In 1912, Henry Ernest Cooper bought the daughters' inherited rights to Palmyra from their legal guardian and petitioned to register Torrens title to all of Palmyra for himself but, after a challenge in court, Cooper's ownership of the atoll was held by the Supreme Court of Hawaii to be subject to rights sold by Ringer's widow to Henry Maui and Joseph Clarke. Maui's and Clarke's interests, noted by the U.S. Supreme Court in 1947, were deeded as to one-third to Mrs. Bella Jones of Honolulu in 1912  and the rest passed to their heirs. 
Cooper visited the island in July 1913 with the scientists Charles Montague Cooke, Jr., and Joseph F. Rock, who wrote up a scientific description of the atoll. Botanist Rock discovered unusual coconut palms in 1913, which palms expert Odoardo Beccari identified as Cocos nucifera palmyrensis (Becc.), the coconut type with the largest, longest and most triangular (in cross-section) fruits in the world, existing only at Palmyra. (The apparently closest Cocos nucifera relative occurs only in the distant Nicobar Islands, India in the Indian Ocean.)  The "mammoth coconuts" were put on display in Honolulu in 1914 along with paintings of Palmyra by Hawaiian artist D. Howard Hitchcock,  who had accompanied Cooper to the island. 
In September 1921, as part of a national push to better document the coastal and outlying areas owned by the United States, a small naval detachment was sent to Palmyra to conduct the first aerial surveys of the atoll. The events of that trip were recorded by a naval Pharmacist Mate, M. L. Steele, who wrote:
During our visit the weather was delightful. The detachment remained at these islands two days and they were perfect for flying, affording an opportunity to take wonderful aerial pictures. The commanding officer and the aviators made a number of flights and the official photographer was in his element.
At the time, Palmyra was occupied by three Americans, two of whom were married. While there, the U.S.S. Eagle 40, which had transported the aircraft and photographic equipment to the islands, made a very rare exception to naval regulation and took aboard the wife, Mrs. Meng, to return her to Honolulu for medical aid as she was not handling the isolation and trying physical conditions of Palmyra well. 
On August 19, 1922, Cooper sold his interest in the whole atoll except two minor islets to Leslie and Ellen Fullard-Leo for $15,000 (equivalent to $229,115 in 2019). They established the Palmyra Copra Company to harvest the coconuts growing on the atoll. Their three sons, including actor Leslie Vincent, continued as the owners afterwards, subject to a period of military administration and construction by the Navy before and during World War II from 1939 through 1945. In 2000, The Nature Conservancy, Inc. acquired the majority of Palmyra Atoll from the Fullard-Leo family for $30 million (equivalent to $44,539,130 in 2019). 
A number of memoirs, reports and unofficial documents in the decades since World War II, have stated Palmyra was placed under naval jurisdiction in 1934, as part of Executive Order 6935.  However, Palmyra is not mentioned in this order, in any capacity. The first official mention of Palmyra as being under Naval Jurisdiction comes from a 1939 letter from the US Attorney General, mentioned in a 1997 Insular Areas report, concluding "Palmyra was U.S. public land and that the Fullard-Leo claim was invalid. S. Rep. No. 83-886 at 37."  Soon after this determination, President Roosevelt issued Executive Order 8616, officially, "Placing Palmyra Island, Territory of Hawaii, Under the Control and Jurisdiction of the Secretary of the Navy". 
Starting back in 1937, the Fullard-Leo family began attempts to lease Palmyra to the U.S. Navy. During negotiations, the government filed a quiet title action against the Fullard-Leos and Henry Ernest Cooper's six surviving children, claiming that there had never been any private property at Palmyra under the Kingdom of Hawaii or later. The case went all the way up to the Supreme Court. The previously mentioned Insular Areas report goes on to state, "While the suit was pending during World War II, the Navy occupied Palmyra and built a runway and several buildings." The Fullard-Leos and Coopers finally won their case in United States v. Fullard-Leo et al., 331 U.S. 256 (1947), which quieted good land title against the federal government in favor of private landowners. The opinion acknowledged certain of Henry Maui's and Joseph Clarke's interests (331 U.S. 256 at 278) but their heirs and their successor Mrs. Bella Jones were not made parties to the case.  As of 2007 [update], descendants of Henry Cooper still owned two small Home islets in the southwestern tip that were not sold in 1922. 
In July 1938, Secretary of the Interior Harold L. Ickes wrote a letter to President Roosevelt, imploring him not to turn Palmyra over to the US Navy for use as a military base. Quoting his letter, he writes,
...the Navy Department has plans for the acquisition and development of the island as an air base. Our representatives have studied conditions at Palmyra and other islands in the south Pacific, and they report that use of this small land area as an air base for Navy Department purposes would undoubtedly destroy much, if not all, that makes the island one of our most scientifically and scenically unique possessions.
The letter was unsuccessful, and plans for the base proceeded. 
On February 14, 1941, President Franklin Roosevelt issued Executive Order 8682 to create naval defenses areas in the central Pacific territories. The proclamation established "Palmyra Island Naval Defensive Sea Area" which encompassed the territorial waters between the extreme high-water marks and the three-mile marine boundaries surrounding the atoll. "Palmyra Island Naval Airspace Reservation" was also established to restrict access to the airspace over the naval defense sea area. Only U.S. government ships and aircraft were permitted to enter the naval defense areas at Palmyra Atoll unless authorized by the secretary of the navy.
The Navy took over the atoll for use as the Palmyra Island Naval Air Station on August 15, 1941. From November 1939 through 1947, the atoll had resident Federal Government representatives, the island commanders. The atoll was shelled by a Japanese submarine in 1941, with no significant damage or injuries. The government made extensive alterations to the land forms. It blasted and dredged a ship channel from the open sea into the West Lagoon, which had been completely enclosed by islands and reef and was non-navigable until the channel reached the lagoon on May 15, 1941. It joined islands with causeway roads, built new islands and extended existing islands with dredged coral spoil, including the main runway on Cooper Island, an emergency landing strip called Sand Island joined by a causeway to Home Island, and two artificial runway islands that were not completed. These alterations blocked the water flow through the atoll and are believed to have severely harmed the natural ecology of the lagoons. 
In the lobby of the "Transient Hotel" (built by the Seabees, and used by airmen on their way to the Pacific Theatre front), a mural was hung depicting a quiet island scene. It was painted by Academy Award-nominated art director William Glasgow, who served in the Army from 1943 to 1945, though it is unclear when he painted it and how it ended up on Palmyra. 
After World War II, much of the Naval Air Station was demolished, with some of the materials piled up and burned on the atoll, dumped into the lagoon, or in the case of unexploded ordnance on some islets, just left in place. 
When Hawaii was admitted to the United States in 1959, Palmyra was explicitly separated from the new state,  remaining a federal incorporated territory, to be administered by the secretary of the interior  under a presidential executive order. 
In 1962, the Department of Defense used Palmyra as an observation site during several high-altitude nuclear weapons tests high above Johnston Atoll. A group of about ten men supported the observation posts during this series of tests, while about 40 people carried out the observations. 
In early 1979, the US government began exploring the idea of storing nuclear waste on remote Pacific islands, like Palmyra. Those who knew the island and the region saw no benefit to this idea, commenting on the devastating effects a leak of these storage tanks would create.  By 1982 a formal proposal had been written which:
analyzes the proposal to store spent nuclear fuel on Palmyra Island, a US territory nearly a thousand miles south of Hawaii. The proposal has military, political, social, and technical implications. 
The idea was abandoned soon after the proposal, and no such storage facilities have been built.
In 1974, Palmyra was the site of a murder, and possible double murder, of a wealthy San Diego couple, Malcolm "Mac" Graham and his wife, Eleanor "Muff" Graham.  The mysterious deaths, including the murder conviction of Duane ("Buck") Walker (a.k.a. Wesley G. Walker) for Eleanor Graham's murder, and the acquittal of his girlfriend, Stephanie Stearns, made headlines worldwide, and became the subject of a true crime book, And the Sea Will Tell, written by Bruce Henderson and Vincent Bugliosi, Stearns's defense attorney. The book led to a CBS television miniseries of the same name, starring James Brolin, Rachel Ward, Deidre Hall, and Hart Bochner; Richard Crenna played lawyer Bugliosi. The story was also depicted in The FBI Files.
Walker and Stearns were arrested in Honolulu in 1974 after returning from Palmyra aboard Sea Wind, the yacht stolen from the Grahams. Because no bodies were found at the time, Walker and Stearns were convicted only for the theft of the yacht. Six years later, a partially-buried, corroded chest was found in a lagoon at Palmyra, containing Eleanor Graham's remains. Walker and Stearns were arrested in Arizona for murder, and Walker was convicted in 1985. Stearns was acquitted in 1986 after her defense argued that Walker had committed the murders without Stearns's knowledge. Because no body or any other evidence of Malcolm Graham's death has been discovered, his murder has never been formally alleged.
Walker served 22 years in the United States Penitentiary, Victorville, California before receiving parole in 2007. He wrote an 895 page book about his experiences, and life on Palmyra Island, in which he denied killing Eleanor Graham. It states they had sexual relations, her husband Malcolm Graham caught them and shot at them in anger, inadvertently killing her. The two men had a gunfight the next day, and Malcolm Graham consequently died from a rifle wound.
Walker accused author Vincent Bugliosi – Stearns' lawyer – of vainglory and exploiting class prejudice against him, and wrote that his own lawyer Earle Partington was incompetent. Walker did not implicate Stearns in any killing.  Walker died in a nursing home, on April 26, 2010, following a stroke. 
In the late 1990s, Rachel Lahela Kekoa Bolt, a native Hawaiian heir of Henry Maui, and some of her descendants filed federal lawsuits claiming her inherited interest in Palmyra and challenging the legality of the Newlands Resolution that annexed Hawaii in 1898 by simple majorities in Congress (after an Annexation Treaty had failed to get the required two-thirds majority in the U.S. Senate). The lawsuits challenged American sovereignty over both the State of Hawaii and the United States Territory of Palmyra Island.   On similar grounds they intervened in a federal marine salvage claim for a sunken treasure ship at Palmyra.  The cases were dismissed on procedural grounds before trial.
In December 2000, The Nature Conservancy, Inc. bought most of Palmyra Atoll from the three Fullard-Leo brothers  for coral reef conservation and research. In 2003, a scientific study was published about fossilized coral that was washing up on Palmyra. This fossilized coral was examined for evidence of the behavior of the effect of El Niño on the tropical Pacific Ocean over the past 1,000 years. 
On January 18, 2001, Secretary of the Interior Gale Norton signed an order designating Palmyra's tidal lands, submerged lands and surrounding waters out to 12 nautical miles (22 km) from the water's edge as a National Wildlife Refuge. Subsequently, the Department of the Interior published a regulation providing for the management of the refuge. 66 Fed. Reg. 7660-01 (January 24, 2001). The pertinent part of the regulation states as follows:
We will close the refuge to commercial fishing but will permit a low level of compatible recreational fishing for bonefishing and deep water sportfishing under programs that we will carefully manage to ensure compatibility with refuge purposes. . . . Management actions will include protection of the refuge waters and wildlife from commercial fishing activities.
In March 2003, The Nature Conservancy conveyed 416 acres (1.68 km2) of the emergent land of Palmyra to the United States to be included in the refuge. In 2005, it subsequently added 28 more acres to the conveyance. The Nature Conservancy and Henry Ernest Cooper's descendants kept their remaining private land tracts at Palmyra.
The conveyance of Palmyra land to The Nature Conservancy, Inc. from the Fullard-Leos in 2000 was subject to a preexisting commercial fishing licence. Then in 2001 the secretary of the interior banned commercial fishing near Palmyra but allowed sport fishing, as quoted above. In January 2007, the commercial fishing licensees sued the United States in the Court of Federal Claims alleging that, under the Takings Clause, the Interior Department regulation had "directly confiscated, taken, and rendered wholly and completely worthless" their purported property interests. The United States filed a motion to dismiss the lawsuit, and the court granted the motion.  On April 9, 2009, the court's decision was affirmed by the Court of Appeals for the Federal Circuit. 
The Pacific Remote Islands Marine National Monument, comprising Palmyra Atoll, Baker Island, Howland Island, Jarvis Island, Johnston Atoll and Kingman Reef, was established on January 6, 2009, by proclamation of President George W. Bush. The secretary of the interior has delegated the responsibility for supervising this national monument to the U.S. Fish and Wildlife Service. 
Limited visits to the refuge are allowed, including by private recreational sailboat or motorboat. Visits must have prior approval, with access to Cooper Island arranged through the Nature Conservancy. 
Rats probably reached Palmyra on U.S. Navy ships during World War II, when a runway was built. In 2011, the U.S. Fish and Wildlife Service, the Nature Conservancy, and Island Conservation began an extensive program to eradicate the large population of non-native rats that had arrived on Palmyra during World War II. As many as 30,000 rats once roamed the atoll, eating the eggs of native seabirds and destroying the seedlings of one of the largest remaining stands of Pisonia grandis trees in the Pacific. These efforts were successfully concluded in 2012 with respect to rodent removal; however, fifty-one animal samples representing 15 species of birds, fish, reptiles and invertebrates were collected for residue analysis during systematic searches or as nontarget mortalities. Brodifacoum residues (the toxicant employed during the project) were detected in most (84.3%) of the samples analyzed with unknown long-term and sublethal effects.   One side effect was the demise of the island's population of Asian tiger mosquitoes. This was claimed to be the first time that killing off one unwanted species resulted in the removal of a second unwanted species. The other mosquito species on the island, Culex quinquefasciatus, was not eliminated. 
Palmyra Atoll's location in the Pacific Ocean, where the southern and northern currents meet, results in its beaches becoming littered with trash and debris. Plastic mooring buoys and plastic bottles are plentiful on the beaches of Palmyra. 
Tourists are allowed to visit Palmyra Atoll.  (This is in contrast to most of the U.S. Minor Outlying Islands, which are mostly closed to the public.) However, there is no easy way to visit Palmyra Atoll, and so very few visit.  Visits must have prior approval.  The U.S. Fish and Wildlife Service says the following:
"Public access to Palmyra Atoll is self-limiting due to the very high expense of traveling to such a remote destination. The Nature Conservancy owns and operates the only airplane runway on Palmyra, and by boat it's a 5–7 day sailing trip from Honolulu. There are four ways the public may gain access to the refuge: (1) Working for, contracting with, or volunteering for The Nature Conservancy or Fish and Wildlife Service; (2) Conducting scientific research via Fish and Wildlife Service Special Use Permits; (3) Invitation through The Nature Conservancy sponsored donor trip; (4) Visitation by private recreational sailboat or motorboat." 
Since the 1940s, Palmyra's most consistent visitors have been members of distance expedition (" DX") teams, as the atoll is a popular spot for these amateur radio operators. To date, more than 25 expeditions have been carried out. Once on the islands, the hams broadcast various signals, attempting to reach as many recipients as possible. Each recipient is eligible to receive a QSL card as confirmation of the connection. Former N. California DX Club president Richard Malcolm Crouch became a Palmyra landowner. 
The visits are often benign, but have occasionally included a bit of drama. For instance, the June 1974 team helped rescue a couple whose ship had run aground on the reefs around Palmyra. The man, Buck Walker, would later be convicted of homicide in the much publicized Sea Wind murder case.  Two members of the 1980 team were injured severely enough on the atoll to need an airlift back to Honolulu. The first incident resulted from injuries sustained in a plane crash as their aircraft underestimated wind conditions on the atoll and the poor state of the landing strip. The second injury, to a surgeon, happened when he fell and cut his hands on broken glass. The surgeon then sued the owners of Palmyra, as he was no longer able to practice surgery, and the atoll was closed to visitors for most of the 1980s while cleanup activities were undertaken.
