Its work includes freeing and caring for captive bears in India[2] and Armenia, rescuing and rehabilitating orangutans [3] and other primates in Indonesia and treating injured and orphaned wildlife in Costa Rica.

[6] The organisation began by running a sanctuary in the southwest of England for domestic and farm animals until, in 1998, it opened a clinic in Goa, India for stray dogs and cats.

In 2009, YIARI's program director in Indonesia, vet Karmele Llano Sanchez, was called upon to treat a wound caused by the shackle on a captive orangutan in Pontianak, West Borneo.

[14] In June 2014 YIARI's primate rehabilitation centre in West Java joined the orangutan facility in receiving GFAS accreditation.

[16][17] IAR's ‘Tickling is Torture’ campaign, also launched in 2015, was designed to expose the inherent cruelty of keeping slow lorises as pets.

[18] Additionally, an ambitious tree-planting project that aimed to plant 650,000 trees and reforest an area of land lost in the fires was launched by YIARI in 2016.

[22] Also in 2017, with partners the Foundation for the Preservation of Wildlife and Cultural Assets (FPWC) IAR launched a campaign to rescue as many as 80 caged bears living in shocking conditions in Armenia.

The Kalandar tribespeople who danced the bears were taught new trades such as rickshaw driving or carpet weaving to help them support their families.

In addition to rescue, rehabilitation and release this centre provides offices from which the team campaigns and assists local authorities in efforts to tackle the illegal trade of slow lorises.

[45] YIARI, International Animal Rescue's Indonesian partners, run a number of holistic conservation and social initiatives including reforestation, habitat protection, Wildlife protection patrols, organic farming training,[46] the provision of alternate livelihoods and the establishment of The Power of Mama, Indonesians first all female fire fighting force.

[47][48][49] In October 2017, IAR partnered with Armenian group Foundation for the Preservation of Wildlife and Cultural Assets (FPWC) to free brown bears being kept in captivity across Armenia.

International Animal Rescue's veterinary teams in India and Indonesia routinely sterilise stray cats as a means of reducing and controlling their populations.

For many years International Animal Rescue was involved in the campaign to end illegal hunting in Malta by supporting the work of the wildlife protection unit of the police known as the ALE (Administrative Law Enforcement.)

Volunteer bird guards recruited from all over the world and trained by CABS are based in Malta to monitor migration and record any illegal shooting or trapping.

A control room is set up and staffed day and night and the police are alerted immediately to any illegal activity so that their patrols can respond swiftly and track down the culprits.
