Elephant
In 2008, the IUCN listed the Asian elephant as endangered due to a 50% population decline over the past 60–75 years while CITES lists the species under Appendix I. Asian elephants once ranged from Syria and Iraq (the subspecies "Elephas maximus asurus"), to China (up to the Yellow River) and Java. It is now extinct in these areas, and the current range of Asian elephants is highly fragmented. The total population of Asian elephants is estimated to be around 40,000–50,000, although this may be a loose estimate. It is likely that around half of the population is in India. Although Asian elephants are declining in numbers overall, particularly in Southeast Asia, the population in the Western Ghats appears to be increasing.
Oregon Zoo
Three female (Sung-Surin "Shine", Rose-Tu, and Chendra; Lily passed away on November 29th, 2018) and two male (Samudra and Samson) Asian elephants are displayed at the popular elephant exhibit. All were born at the zoo, with the exception of Chendra, who was orphaned in the wild; and Samson, who was acquired from the Albuquerque Zoo. Chendra is the only Borneo elephant in the United States. On November 30, 2012, at 2:17 a.m., Rose-Tu and the late Tusko (who are also the parents of Samudra) had a female calf Lily, weighing about 300 lbs (136 kg) at birth. There is a swimming hole in which up to ten elephants can simultaneously completely submerge, sandy ground for comfortable walking and a scratching station, which the elephants often choose to scratch their head, sides, belly, etc. The exhibit was recently enlarged from to , expanding into the same location as the elk and wolves (now gone) once were. Construction for the expansion began in 2013, and included a variety of terrain (meadows, forests, and mud wallows with sand lining the whole enclosure), a timed-feeding system to provide more natural stimulation, and an eco-friendly heating system to keep them warm year-round. Areas of the exhibit such as the Encounter Habitat were completed in summer of 2014, and their new habitat was finished in autumn of 2015.
