My Answer SELECT Forest.Fo_name, Species.Sp_name, Species.Sp_woodtype FROM Forest INNER JOIN Species ON Tree.Tr_species=Tree.Tr_forest WHERE Fo_loc='ARTIC' ORDER BY Fo_name, Sp_name "For forests found in the regions coded as "ARTIC" list the forest name & species name and species wood type found therein.
