The Natterjack Toad (Epidalea calamita) is a protected species in Latvia, their numbers continue to decrease. In 2010–2013 a total of 338 young Natterjack Toads, bred in the Zoo's Laboratory of Ecology, were released into the wild in Garaiskalns protected nature area to supplement and strengthen the existing wild population there.

Riga Zoo takes care of wildlife casualties, rehabilitating them and, where possible, releasing them back into the wild. In 2008–2017, 377 wild animals where admitted to the Zoo's Quarantine station. 228 of them were rehabilitated successfully and 77 were released back into the wild.
Rehabilitation work is conducted both by the Zoo in Riga and Affiliate Cīruļi. For example, in 2002, when a severe storm in Southern Latvia destroyed many White Stork (Ciconia ciconia) nests and in addition to this a drought in July–August made stork's food source scarce, 21 White Storks were admitted to Zoo's Affiliate Cīruļi. 11 young were rehabilitated successfully, and nine of them were able to join the wild stork autumn migration to Africa.
Since the space and resources of the Zoo are limited it is not able to provide help in all cases. A number of wildlife rehabilitation centers that have been created in Latvia in recent years are also prepared to help wild animals in trouble. The Zoo conducts education campaigns to raise public awareness and prevent wild animals from ending up in unnecessary captivity.

Riga Zoo undertakes the rehabilitation of stranded seal pups found on shores of the Baltic Sea and the Gulf of Riga. In 1983–2017, 138 seal pups were brought to the Zoo. 66 of them were rehabilitated successfully. The rehabilitated seals were included in the Zoo's animal collection, sent to other zoos or released back to the sea. In 2002–2017 a total of sixteen rehabilitated young seals were released back to the Gulf of Riga. All individuals were equipped with flipper tags. There have been no reports that any of the tagged specimens has been found.

In 2005, a campaign was launched together with Daugavpils Zoo, calling on people to report all sightings of the rare native European Pond Turtle (Emys orbicularis). The project was funded by the Environmental Protection Fund of Latvia.

In 2010, a Turtle Sanctuary was opened in Riga Zoo's Quarantine station, inviting people to take their unwanted pet turtles to the sanctuary rather than release them into the wild. In 2003–2017, a total of 413 turtles of various exotic species were admitted to the Zoo. Most of them were Red-eared Sliders of various subspecies. The Turtle Sanctuary has helped educate people, as well as find new homes to the turtles arriving at the Zoo.

Each spring since 1952 Riga Zoo organizes Bird Day with Woodpecker's Workshop where visitors learn how to make nest boxes for different cavity nesting birds from materials supplied by the Zoo. Every year several hundreds of nest boxes for small cavity nesting birds (tits, flycatchers, redstarts) and starlings are made. Each year we also highlight the conservation problems of some rare species, and nest boxes constructed for this species are set up within protected nature areas in Latvia supporting the research and conservation of these species in the wild. These highlighted species have included Common Kestrel (2006), Goldeneye (2008), Barn Owl (2009), Ural Owl (2010), Tawny Owl (2011, 2012), European Roller (1013), Hoopoe (2014), Little Owl (2017), Boreal Owl (2018) as well as Forest Dormouse (2007, 2015, 2016). Among Bird Day supporters were Nature Conservation Agency, Latvian Ornithological Society and Latvian Owl Research Society.
