where is the brown tree snake found in the us
Brown tree snake Shortly after World War II, and before 1952, the brown tree snake was accidentally transported from its native range in the South Pacific to Guam, probably as a stowaway in ship cargo or by crawling into the landing gear of Guam-bound aircraft.[2][5][6] As a result of abundant prey resources on Guam and the absence of natural predators outside of feral pigs and mangrove monitors, brown tree snake populations reached unprecedented numbers. Snakes caused the extirpation of most of the native forest vertebrate species; thousands of power outages affecting private, commercial, and military activities; widespread loss of domestic birds and pets; and considerable emotional trauma to residents and visitors alike when snakes invaded human habitats with the potential for envenomation of small children. Since Guam is a major transportation hub in the Pacific, numerous opportunities exist for the brown tree snakes on Guam to be introduced accidentally to other Pacific islands as passive stowaways in ship and air traffic from Guam.[2] To minimize this threat, trained dogs are used to search, locate, and remove brown tree snakes before outbound military and commercial cargo and transportation vessels leave the island.[7] Numerous sightings of this species have been reported on other islands including Wake Island, Tinian, Rota, Okinawa, Diego Garcia, Hawaii, and even Texas in the continental United States.[8] An incipient population is probably established on Saipan.[2] Acetaminophen has been used to help eradicate the snake on Guam.[9]
Rattlesnake Rattlesnakes are native to the Americas, living in diverse habitats from southwestern Canada to central Argentina. The large majority of species lives in the American Southwest and Mexico. Four species may be found east of the Mississippi River, and two in South America. In the United States, the states with the most types of rattlesnakes are Texas and Arizona.
