Ili Pika range
Almost nothing is known about the ecology or behavior of this species.
O. iliensis exhibits low population densities. It is mostly a diurnal species, but may exhibit nocturnal activity. Only one to two litters are produced each year, but litter size for this species is unknown.
Its population has been reduced by 55% within 10 years. Population declines have been observed for several locations inhabited by this species. A recent census indicated that Ochotona iliensis may be extirpated from Jilimalale and Hutubi South Mountains. Populations have declined in the regions of Jipuk, Tianger Apex, and Telimani Daban. Only one examined site, the Bayingou region, showed signs of previously observed abundance. An estimated 2,000 mature individuals existed in the early 1990's. The exact causes for recently observed population declines are not known, but it is speculated that an increase in grazing pressure and global atmospheric pollution resulting in climate change are negatively impacting Ochotona iliensis populations. Low population densities and reproductive rates coupled with the relatively limited ability to disperse impede the ability of the species to recover from declines. There are no known conservation measures in place for Ochotona iliensis.
