Results of CSI Pollen in Cordoba (Spain) for 2015: Urban Apiary the best.
Apoidea. Spin-off from University of Córdoba.
The study was conducted in the municipality of Córdoba in southern Spain. The town lies in the valley of the Guadalquivir River between the mountains of the Sierra Morena (to the north) and the Guadalquivir Valley (to the south). The municipality is 1255.2 km2 in area with a population of 328,547 inhabitants in 2010.
Biomonitoring stations installed at five sites were used to assess environmental quality (heavy metal pollution, pesticides and solitary bees) since 2007 to 2011. Now, CSI Pollen project was conducted since April to September in 2015 at the same five sites:
Station 1 was located west of Córdoba in a plot at the Agricultural Experimentation Centre (IFAPA). Proximity to the Guadalquivir River allowed the honeybees to access riparian vegetation.
Station S2 was installed on agricultural land approximately 15 km south of the city. The landscape is without natural vegetation and has been parcelled into large farms of predominantly cereal and sunflower crops; uncultivated space is practically non-existent.
Station S3 was in Sierra Morena, 8 km north of the city at an altitude of 577 m. The study area was predominantly Mediterranean forest, and a nearby recreational park was included.
Station S4 was located in downtown Córdoba on the rooftop of an historic monument, “Malmuerta Tower”. Ornamental plants in gardens and on streets were the most accessible food sources for the bees.
Station S5 was located east of the city in an abandoned quarry with Mediterranean vegetation but few trees.
The results show us that in Station 4 (urban apiary), the quantity and variability of pollen colours were greater.
