Friends of Nairobi Arboretum (FONA) was founded in 1993, under the umbrella of Nature Kenya (East Africa Natural History Society), by a group of people concerned about the neglect and decline of the arboretum during the 70s and 80s due to lack of govern­ment funding.

Its aim was to assist the Forest Department (now Kenya Forest Service - KFS) to revitalize and develop the Arboretum into a modern facility for promoting environ­mental education, recreation and scientific knowledge. Since 1993 FONA has been engaged in numerous physical improvements efforts at Arboretum e.g. providing benches, seats, picnic tables, a Shelter Banda, litter collection, grass cutting etc. FONA continues to work alongside KFS to maintain this green gem for recreation, education and scientific knowledge. Under the Forest Act 2005, FONA is registered as a Community Forest Association (CFA), thus enhancing community participation in the management of forest reserves.
