Th e following prelim inar y plant spec ies list is suggested to be used in natural reco ver y a nd rest or at ion of polluted sites: A eloropus lagopoides, A izoon canariense , Anabasis ole(ifera, Cyp erus cong lom eratus , Fagon ia o valij olia, Herniari a hemist emo n, Launuea procumbens, Oligom eris subulata, Reichardia tingtuna , Salsola baryosma , Schan ginia aegyptiaca , Senecio desj onta inei , Zygophllum quatarense a nd Z yg ophylium simp /ex . T o facilit at e natural plant in vasion and rest or ation o f tar piles , the dumping sites mu st ha ve plant co mmunities with high species diversity and hig h percent age of annu al plants . Depending on sandtar ratio in the pile s . a rtificial see d ing of se lec ted plant species ca n be appli ed by usin g species mixes o r single spec ies see d ing. Managem ent co nside ra tio ns a re sugge ste d to opt imize the natural recovery a nd restoration of tar affecte d coastal marshes.
