The recent growth of low-density urban developments in the Mediterranean coast has led to an increase in the number of private domestic gardens. This thesis examines the flora, features and management practices of 258 private gardens in the Alt Empordà region in Catalonia. We also calculated water requirements of gardens based on species composition and land cover, and determined whether they can be predicted from the socioeconomic, demographic and cultural characteristics of households. Of the 635 taxa identified, 68% were exotic. Moreover, 39 species have been considered potentially invasive in Spain, although only 25 were present within the limits of the adjacent Aiguamolls de l’Empordà Natural Park. The distribution of garden floras was significantly related to different socioeconomic and demographic gradients, such as the occupancy rate of the house, the origin of the residents, their income level and the percentage of unemployed members. ​
