Relations with other habitat types

It is mostly coincident with EUNIS level V unit S3343 (“Northwestern Iberian Cytisus fields"), but its neat ecological and biogeographical in the ecoregion deserves recognition at level IV. It tends to appear at lower elevations than S33w (i.e. successionally associated to woodlands of the units T1Bx and T211 —or transitions thereof—rather than T19A).
