Portugal has tradition in the production of almond, mainly in Trás-os-Montes and in the Algarve, but more recently with the Alqueva dam, large almonds plantations (intensive and superintensive) are being born in the Baixo Alentejo. The walnut is produced a little throughout the country, with emphasis on Trás-os-Montes, Beira Litoral, Alto Alentejo, Ribatejo and Oeste, while the pine nut is concentrated in the district of Setúbal (mainly in Alcácer do Sal).
