In 1983, 27 Rothschild giraffes (Giraffa camelopardalis rothschildi) were translocated from Soi Ranch in Kenya's Rift Valley to Ruma National Park (NP). This measure was taken to both conserve the giraffes, and to enrich the park with new species. In July 2002 a team from OSIENALA (Friends of Lake Victoria) conducted a survey at Ruma NP to determine both the current giraffe populations and the impact of their introduction. The study found the giraffe population to be approximately 75. The giraffes' preference at Ruma NP was found to have an impact both on the environment and the human communities that surround the park.
