In this work, we address the existence and origin of the lithium (Li) desert, a region in the Li-Teff plane sparsely populated by stars. We measure stellar parameters and lithium abundances of 227 F-dwarfs and create, using literature measurements, an homogeneous catalog of 2318 stars for which we compute masses and ages. We suggest that stars below the Li desert are consistent with having evolved from the Li dip, discarding the need to invoke additional mixing to explain this feature. Thus, stars below the Li desert are not peculiar and are only distinguished from other subgiants evolved from the Li dip in that their combination of atmospheric parameters locates them in a range of effective temperatures where otherwise only high Li abundance stars would be found.
