Collecting Seeds and Fruits of the Native dune flora in Marbella
17th NOVEMBER 2020 – DUNE AREA “RESERVA DE LOS MONTEROS”, Río Real-Reserva de los Monteros
Collection of seeds of the wonderful Sea daffodil (Pancratium maritimum) and dune conservation
JUNIPER POLLINATION (Juniperus macrocarpa)
In La Adelfa dune there are several specimens of Maritime Juniper that do not have fruit. This is because they are young specimens and have not yet flowered. Fruit is found on some branches and not on others for the same reason. The fruit can have different colours depending on the year and their state of maturity.
Each specimen has branches with male flowers and branches with female flowers when mature. The male flowers produce pollen, which pollinates the female flowers, giving galbule-like fruits.
Pollination is mainly by wind.
SHORT EXPLANATION ON THE DIFFERENCE BETWEEN JUNIPERS AND SABINAS IN DUNAR ENVIRONMENTS
Sabina (Juniperus turbinata)
Junipers have overlapping leaves like roof tiles and are soft to the touch.
Maritime juniper (Juniperus macrocarpa)
Junipers have spiky leaves with one or two white stripes.
They belong to the cupresaceae family.
- Juniper phoenicea is a monoecious species, which means that the male, small and terminal flowers coexist on the same arboreal foot with the female, auxiliary ones, which after two years mature into cones of up to 14 mm, ovoid, waxy green and toning into a dark red finish. The male flowering branches have cones in the axils of the leaves, which produce a lot of pollen that is dispersed by the wind in spring.
- Large-fruited Juniper is a dioecious plant, the solitary and cylindrical male cones are on different bases from the female ones and it is distinguished by its needle-like leaves with two white bands on the upper face and its mature cones of between 7 and 15 mm, formed by 3 fleshy scales, welded together. They house 3 seeds. They go through different colours to black in their second year of maturation
It is not unusual to find galbules in different stages of maturity on the plant.

THE INTERESTING FUTURE FOR BIODIVERSITY IN OUR DUNE ENVIRONMENT
A door has just opened unexpectedly for us to work directly and take part in spreading the beautiful biodiversity which we have in the dune environments in the Natural Monument “Dunas de Artola”, as well as in the Ecological Reserve-“Dunas de Marbella”.
A family business situated in Cordoba has, for many years, been enthusiastically collecting, producing (organic crops) and commercialising the seeds and fruit of our Spanish wild native plants (more than 850 different species). They form part of the official Collaborating Entity of the Ministry of Agriculture, Livestock, Fisheries and Sustainable Development. Their interest is mainly focused on the Mediterranean area which is where our Association comes in, as we look after 500,000 m² of dune environment, stretching from the Natural Monument “Dunas de Artola” to the Ecological Reserve-Dunas de Marbella.
The project of Collecting Seeds and Fruits of the Native Dune flora will be a demanding and beautiful challenge, since we will become part of ensuring that the biodiversity prospers and spreads throughout all these dune environments, by reintroducing seeds from different native plant species to the targeted areas.
We are preparing annual collection programs, 8 native species per year for three years, for their re-introduction to the different ecosystems along the coastline of the Costa del Sol.
Biodiversity is life and the seeds of our native wild flora will bring biodiversity
There are some dune areas that still need a profound landscape restoration and where it will be especially satisfying to see how man’s intervention can be positive. Botanic biodiversity using genetically healthy, thriving plants encourages pollination of the vegetation, which in its turn shelters the entomofauna that includes insects and other arthropods.
At the same time, phytogenetic traceability is guaranteed thanks to strict control exercised by the Ministry of Agriculture, Livestock, Fisheries and Sustainable Development. The pertinent authorisations extended to ProDunas will provide the basis for guarantees regarding specific conservation and / or the reintroduction projects for the selected species.
This joint collaboration must be a lasting project. This is why our Association is seeking to work with different Spanish universities, some of which are already visitors to the Marbella dunes; organisations involved in research into genetic improvement, as well as schools, foundations and companies in general who would like to get involved in this amazing project.
Working together like this will ensure the advancement in understanding the autochthonous flora.
We would like to make it clear that involvement by third parties in this project will always be on an altruistic basis.
