Stenocercus haenschi has been assessed as Critically Endangered under criteria B1ab(iii). as it is only known from one location, with an inferred extent of occurrence of less than 100 km², with extensive survey work failing to expand this distribution. Survey work has failed to find any specimens, which suggests that this species could possibly be Extinct (it is therefore tagged as being 'Possibly Extinct'). If it does still exist in its previous range it is threatened by habitat loss, where the natural vegetation has been replaced by plantations. Future surveys are needed to confirm if this species is in fact Extinct.
This species is only known from its type locality, Balzapamba, Provincia Bolivar, Ecuador, at 750 m above sea level. The type locality is in the upper valley of the Rio Babahoyo, which drains into the Pacific.
This species is known only from its type locality, where it was last collected in 1901; Torres-Cavajal (2000) visited the type locality in 1997 but found no specimens. More intensive surveys are needed to confirm this species as Extinct, in its type locality and areas of suitable habitat.
