[2] Panthera tigris corbetti was proposed as a scientific name for this specific population by Vratislav Mazák in 1968 based on skin colouration, marking pattern, and skull dimensions.

[1] Results of a genetic study published in 2018 supported six monophyletic clades based on whole genome sequencing analysis of 32 tiger specimens.

[9] In Myanmar, surveys were conducted between 1999 and 2002, confirming the presence of tigers in the Hukawng Valley, Htamanthi Wildlife Sanctuary and in two small areas in the Tanintharyi Region.

[11] Camera trap surveys between 2016 and 2018 revealed about 22 adult individuals in three sites that represent 8% of the potential tiger habitat in the country.

[12] More than half of the total Indochinese tiger population survives in the Western Forest Complex in Thailand, especially in the area of the Huai Kha Khaeng Wildlife Sanctuary.

[13] Camera trap surveys from 2008 to 2017 in eastern Thailand detected about 17 adult tigers in an area of 4,445 km2 (1,716 sq mi) in Dong Phayayen–Khao Yai Forest Complex.

[16] In Laos, 14 tigers were documented in Nam Et-Phou Louey National Protected Area during surveys from 2013 to 2017, covering four blocks of about 200 km2 (77 sq mi) semi-evergreen and evergreen forest that are interspersed with some patches of grassland.

[17] More recent surveys have failed to detect any tigers, and the likelihood is that they have been extirpated as a result of poaching, fueled by demand from China.

In Laos, no tiger has been seen since 2013, when its populations were estimated at only two, and these two individuals vanished shortly after 2013 from Nam Et-Phou Louey National Protected Area, denoting they were most likely killed either by snare or gun.

[32] In Thailand's Huai Kha Khaeng Wildlife Sanctuary, seven female and four male tigers were equipped with GPS radio collars between June 2005 and August 2011.

Sambar deer, banteng, gaur, and wild boar were most frequently killed, but also remains of Asian elephant calves, hog badger, Old World porcupine, muntjac, serow, pangolin, and langur species were identified.

[39] In Myanmar's Hukaung Valley, the Yuzana Corporation, alongside local authorities, has expropriated more than 200,000 acres (81,000 ha) of land from more than 600 households since 2006.

China, South Korea, Vietnam, Singapore, and Taiwan banned trade in tigers and sale of medicinal derivatives.

[41] Patrolling in Thailand's Huai Kha Khaeng Wildlife Sanctuary has been intensified since 2006 so that poaching appears to have been reduced, resulting in a marginal improvement of tiger survival and recruitment.
