The objective of the research was to evaluate the wild and cultivated plant diversity in the district of Cajatambo, Lima, in order to contribute to the sustainability of the agricultural system. The records were made during the years 2015 and 2016 through 44 transects of 30 meter in 9 plant formations in the patchwork mosaic determined by photointerpretation: agricultural field, eucalyptus forest, Polylepis forest, scrubland, grassland, lawn, bofedal, gravel and juncal. A total of 355 species, corresponding to 211 genera and 64 families were determined, being Asteraceae, Poaceae, Fabaceae, Caryophyllaceae, Lamiaceae and Solanaceae the families best represented. Thirty-two species were found in some category of threat, some present only in one place such as Ocopata, Iscu-Viconga, Huaylashtoclanca and in San Cristobal Hill, being scrublands, agricultural fields, grasslands and Polylepis forest, vegetal formations where the presence of threatened species has been registrered more. Vegetal diversity in agricultural areas such Parientana, Urpaycocha and Tizapampa grasses was highly variable over time, but with little plant diversity, while the scrublands near the quarry and mine and the Tocanca and Viconga grasslands were less variable and more diverse. The degree of anthropic intervention would determine this behavior. Of the species selected as potentially key, 12 would have a possible shelter pattern, while 4 species a possible pattern of mobile and fixed hot-sposts. The location of shelters allows planning of conservation and sustained exploitation of these resources. Knowledge of the population distribution over time of species that are used as forage, such as Trifolium repens, Medicago polymorpha, Medicago sativa and Cenchrus clandestinus, and others that are mostly collected and used, such as Ambrosia arborescens, Chuquiraga spinosa, Tetraglochin cristatum and Austrocylindropuntia subulata, contributes to their sustainable management. The presence of certain plants in dry season and which are widely used by local residents provide plant resources for subsistence at times when the scarce availability of water makes it more difficult to obtain resources. The use of these wild plants and weeds constitutes an important strategy in the sustainability of the Cajatambo´s agricultural system
