Se pretende analizar su estado para tomar medidas encaminadas a su recuperación, y caracterizar el enclave desde un punto de vista ecológico. Para ello dividió el área de estudio en 26 unidades homogéneas, donde mediante parcelas de 12 m de radio se midió para Quercus suber L. y Pinus pinaster Aiton diversas variables dasométricas, así como características de las parcelas. Se catalogaron más de 150 especies vegetales, muchas de ellas en peligro de extinción, y se obtuvo un número aproximado de 9100 alcornoques, con un fuerte desequilibrio poblacional.

The observations were divided into periods of 15 days, from February 1st to April 30th for the prenuptial migration and from June 1st to October 31st for the postnuptial migration. The peak of the migration was obtained for each one of the following age classes: birds of the year (≤ 1 year), immature (2 years), first breeders (3 years), young breeders (4-5 years) and experienced breeders (≥ 6 years). A total of 226 rings from 12 different breeding colonies were recorded, being 80.5 % of the sightings from the Delta del Ebro colony. The peak of the experienced breeders during the prenuptial migration was obtained during the first fortnight of March. The other age classes had their maximum migration movements later in the season. The results for the postnuptial migration showed a peak for immature gulls during the first fortnight of June. The peak of the first and young breeders during the postnuptial migration was obtained during the end of June and the beginning of July. The experienced breeders had their maximum migration movements at the end of July. In addition, during the postnuptial migration, the age classes considered as breeders (>3 years) showed a second peak migration between the end of August and the beginning of September. This study may provide useful migration data at regional level for the management and conservation of this iconic species classified has vulnerable.
