Question: In what year was the nominate cheetah subspecies, that makes the Entabeni Game Reserve it's home, classified as Vulnerable by the IUCN?

<P0-S0> Lemurs are strepsirrhine primates, all species of which are endemic to Madagascar. <P0-S1>  They include the smallest primate in the world, Madame Berthe's mouse lemur, which weighs 30 g , and range up to the size of the indri, which can weigh as much as 9.5 kg . <P0-S2>  However, recently extinct species grew much larger. <P0-S3>  As of 2010, five families, 15 genera, and 101 species and subspecies of lemur were formally recognized. <P0-S4>  Of the 101 species and subspecies, the International Union for Conservation of Nature (IUCN) classified eight as Critically Endangered, 18 as Endangered, 15 as Vulnerable, four as Near Threatened, eight as Least Concern and 41 as Data Deficient; seven were yet to be evaluated. <P0-S5>  From 2000 through 2008, 39 new species were described and nine other taxa resurrected. <P0-S6>  By 2014, the number of species and subspecies recognized had increased to 105; of these, the IUCN classified 24 as Critically Endangered, 49 as Endangered, 20 as Vulnerable, three as Near Threatened, three as Least Concern and four as Data Deficient; two were yet to be evaluated. <SEP> <P1-S0> The South African cheetah ("Acinonyx jubatus jubatus"), also known as the Namibian cheetah, is the most numerous and the nominate cheetah subspecies native to Southern Africa. <P1-S1>  Since 1986, it has been classified as Vulnerable by the IUCN. <P1-S2>  The South African cheetah live mainly in the lowland areas and deserts of the Kalahari, the savannahs of Okavango Delta and the grasslands of the Transvaal region in South Africa. <P1-S3>  In Namibia, cheetahs are mostly found in farmlands. <P1-S4>  The South African cheetah was first described by the German zoologist Johann Christian Daniel von Schreber under the trinomen "Felis jubatus jubatus" in the Dutch Cape Colony in 1775. <SEP> <P2-S0> The golden swallow ("Tachycineta euchrysea") is a passerine in the swallow family, Hirundinidae. <P2-S1>  Two subspecies are recognised, the Jamaican "T. e. euchrysea" and "T. e. sclateri" of Hispaniola (Haiti and the Dominican Republic). <P2-S2>  It usually inhabits the hills on the interior of islands, preferring open country. <P2-S3>  Currently, this swallow is restricted to isolated montane forests that primarily consist of the Hispaniolan pine. <P2-S4>  This species is considered to be a vulnerable species by the International Union for Conservation of Nature (IUCN), although the nominate subspecies, "T. e. euchrysea", is likely extinct. <P2-S5>  The exact cause of extinction is unknown, but likely factors include predation by mammals and habitat loss, although the habitat loss theory is not supported by very much evidence. <P2-S6>  The last sighting of the nominate subspecies was in Hardwar Gap (located on the boundary between Saint Andrew and Portland parishes), with three birds being seen on 8 June 1989. <SEP> <P3-S0> The Entabeni Game Reserve, Entabeni means 'place of the mountain', is a 220 km2 private reserve situated in the Waterberg in Limpopo Province in northern South Africa. <P3-S1>  The Entabeni Reserve is popular for safari trips because of the opportunity to see big game and a variety of birds and antelope species, as well as its beautiful scenery, and the fact that it is in a malaria-free zone. <P3-S2>  The reserve is home to Transvaal lion, African bush elephant, South African giraffe, African leopard, South African cheetah, warthog, African buffalo, hippopotamus and other safari animals in a variety of habitats.
