Information from Eden's field research, local sources, literature and international research contacts is entered into a database of over 10,000 species, sub-species and varieties. Eden's database includes information on taxonomy, rainfall range, topography, soil, edibility of different plant parts, and other uses such as land use, fuel, chemical uses, fertiliser, etc. Much of the food provided by the perennials is low status food but with high nutrient content. The consumption of such food will especially benefit women and children, who tend not to get as much high status food as men. Meat, for example, is a high status food that men have first priority to when it is served.
Women also get an income from selling fruits of perennial species in local markets.
When the vegetation declines, the wild animals disappear. The way to restore the wildlife again is to increase the vegetation. Perennials provide the local fauna with nesting sites and hiding places from predators. Through the establishment of perennials, Eden has seen several animal species returning to the field station. These include the monitor lizard, desert fox and different birds.
