The Polynesian rat is common on Bikar and Jabwelo. This raised concerns for the important sea turtle and bird nesting sites. The coral fauna lacks diversity and shows signs of frequent storm damage.
The corals include several genera not seen at Taongi Atoll, and the diversity of fish is much greater, including the two-spot red snapper , humpback red snapper, leopard grouper , and humphead parrot fish. Shellfish include the black-lipped pearl oyster , bear paw clam , maxima clam , and the Trochus sea snail. No marine mammals have been seen in the lagoon. Although humans migrated to the Marshall Islands about years ago,  and Bikar was occasionally visited by the Marshallese, there is no evidence that there has ever been a resident human population.
The lack of water and the susceptibility of the atoll to cyclone and storm disturbance indicate that it will probably remain uninhabited.
The atoll has traditionally been used for hunting and gathering, particularly seabirds and turtles, by inhabitants of other atolls in the northern Ratak chain. The exploitation of abundant sea turtles, birds, and eggs was regulated by custom, and overseen by the Iroji.

During the late s, Bikar was the subject of a number of commercial transactions related to the increasing German presence in the Marshall Islands. Spain transferred sovereignty to the Empire of Germany in , and in December, property rights were transferred to the Jaluit Gesellschaft.
In , the Manchester , a four masted steel hulled cargo ship of tons with a load of kerosene, went missing at sea between New York City and Yokohama.
Wreckage and signs of habitation were discovered on Bikar in , suggesting that the ship had come to grief there, and that the survivors had pushed off in lifeboats shortly before the discovery. No sign of the crew or passengers has since been found. In , the Empire of Japan occupied the Marshall Islands, and transferred German government properties to their own, including Bikar. Like the Germans before them, the Japanese colonial administration the South Pacific Mandate did not attempt to exploit the atoll, and the Northern Radak Marshallese continued to hunt and fish unmolested.
In , the U. Geological Survey and the Army Corps of Engineers sponsored an expedition to Bikar and Taongi Atolls, to characterize their primeval environment. The landing party found no signs of any current occupants.
In , the fallout plume from the Castle Bravo nuclear test passed over Bikar about 20 hours after the shot. This experience led to a pre-planned aerial survey of atolls adjacent to the subsequent March 27 Castle Romeo test, timed at one and four hours after the shot. The aircraft were equipped with gamma radiation detectors designed to measure ground contamination from altitudes of to feet.
An overflight of Bikar Island measured 0. In , 19 Japanese fishermen from the fishing boat Daitei Maru No. A study of fish and invertebrates within the lagoon found that the level of radio-nucleotides in muscle tissue was within the range found in fish products imported to the US and Japanese markets. The worldwide source of seafood-borne radio-nucleotides is a result of atmospheric nuclear testing since , and therefore any residual activity from the s Castle series of tests contributes only a small fraction of the contamination within the lagoon's sea life.
Currently, no archaeological remains of Polynesian habitation have been identified. The almost completed corroded wreck of a Japanese fishing boat lies in the north fork of the reef passage.
