The family orchard is a common agroforestry production system from the tropics that usually does not exceed one hectare. This traditional production system differs from others because its vegetation is displayed in multi strata and distributed in different management areas more or less defined. The fieldwork was developed in 2013-2014, in the Ejido La Encrucijada, Cárdenas, Tabasco. The structure and management areas from family orchards were characterized according to their components; to do so, botanical composition, abundance, diameter at breast height, total height, crown cover and plant mapping were performed in each family orchards. The sampling area covered 3.35 ha ($\stackrel{-}{\mathrm{x}}$= 1156 m2). The plants were grouped into four strata, which comprised from 0 to 20 m, being the lower strata the most abundant and diverse. Mangifera indica L., Theobroma cacao L. and Citrus sinensis (L.) Osbeck were the woody species with higher importance value in the floristic inventory. From the components of family orchards two management zones were characterized, with 25 orchards that had an area of woody plants and another of medicinal herbs with ornamental.
