Opuntia Opuntia Opuntia, commonly called prickly pear, is a genus in the cactus family, "Cactaceae". Prickly pears are also known as "tuna" (fruit), "sabra", "nopal" (paddle, plural "nopales") from the Nahuatl word "nōpalli" for the pads, or nostle, from the Nahuatl word "nōchtli" for the fruit; or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary species is the Indian fig opuntia ("O. ficus-indica"). "O. ficus-indica" is a large trunk-forming segmented cactus which may grow to with
Opuntia ficus-indica the Mediterranean basin. Under those hedges and adjacent areas soil physical properties, nitrogen and organic matter are considerably improved. Structural stability of the soil is enhanced, runoff and erosion are reduced, while water storage capacity and permeability is enhanced. Prickly pear plantations also have a positive impact on plant growth of other species by improving severe environmental conditions which facilitate colonization and development of herbaceous species. Opuntia ficus-indica is being advantageously used in Tunisia and Algeria to slow and direct sand movement and enhance the restoration of vegetative cover, minimizing deterioration of built terraces with its deep and strong rooting
