CLEAN UP THE WORLD!

Last September our students took part in an environmental campaign  called "Puliamo il Mondo!", the Italian version of "Clean Up the World". It was meant to be a follow-up of the Green Day, organized in May to restore Villa Margherita in Castelvetrano. But what is "Clean Up the World?
"Clean up the world inspires and empowers communities to clean up, fix up and conserve their environment".

Alongside the collection of succulents, there is an enormous  specimen of Ficus rubiginosa , similar to a tropical jungle.

In the Cycadetum it is possible to admire certain species of cicadi that have a remarkable history:Cycas revoluta; Zamiaceae Ceratozamia mexicana and Dioon edule; Cycas circinalis; Dioon spinulosum, Encephalartos villosus, Macrozamia moorei and Zamia furfuracea. 

As regards palms, you can find Chamaerops humilis  , the only palm native to Sicily, and numerous exotic palms: W. filifera, W. robusta, Phoenix dactylifera, P. rupicola, P. reclinata, P. canariensis, P. roebelinii and p. teophrastii, Chamaedorea, brahea, sabal, Erythea, Livistona, Howea and Trachycarpus.
The Winter Garden has got a number of species native to the warmer climes of Africa, central America, South america, Asia and Australia: Coffea arabica, Carica papaya, numerous species of Bougainvillea, cinnamon (Cinnamomum ceylanicum), Parmentiera cereifera, and mimosa (Mimosa spegazzinii). In the glasshouse of the regions, you can see specimens of Ravenala madagascariensis) (the traveller's palm) and various species of Anthurium, Codiaeum, Pandanus  and other plants from tropical and equatorial  climes. Two smaller glasshouses house orchids and carnìvorous plants  respectively.
In the Experimental zone and zone of practical plantings  there are plants which produce foodstuffs, like Saccharum officinarum and Sorghum saccharatum; Persea americana, various cultivars of Banana (Musa acuminata balbisiana), pecan nut . Lastly you can find the medicinal plantings, including Artemisia absinthium, datura strammonium, gingseng (Withania somnifera9, la camphour (Cinnamomum canphora) and the opium poppy (Papaver somniferum).

MEDITERRANEAN POSIDONIA





The Mediterranean Posidonia, contrary to what you might think, is a marine plant, not an algae. In fact it consists of a root, a stem and leaves that are concerned with the process of photosynthesis.

Its stem, called rhizome, can develop both in horizontal and vertical direction. Nevertheless the leaves develop only from the vertical rhizome. The continuous accumulation of Posidonia forms a network of dead rhizomes called “matte”. These “matte” create a barrier that filters the carbon footprint in the environment thus reducing greenhouse gas emissions in the planet. The growth of “matte” is very slow, that’s why you must avoid destroying them, since it is a phenomenon not replicable on a human scale. In the Mediterranean Sea you can see the phenomenon of the beaching of the Mediterranean posidonia. This natural process, that is not harmful to environmental ecology, damages the tourist economy of the place.  For this reason  the particular composition of posidonia has been exploited either for removing it from beaches or for using it for economical purposes. Because of this, a particular type of compost ,acting as soil conditioner, has been created.The advantages of the compost are as follows:

  • Increase in the porosity of the soil
  • Increase in the bioavailability of soil microflora

SANTA NINFA NATURE RESERVE & LEGAMBIENTE (SICILY): ONE OF OUR LOCAL PARTNERS


The Santa Ninfa Grotta nature reserve was instituted by the Sicilian Region in 1995 and  its management was entrusted to Legambiente Sicilia, which deals with the tutelage and valorisation of the site, scientific research and  enjoyment of nature, and environmental education. The territory of the reserve, which is located  2.5 km from the village of Santa Ninfa, has been divided into two areas with different peculiarities:

§Zone A, comprising the hypogean parts of the Grotta;

§Zone B, comprising the Biviere Valley corresponding to the basin feeding the cave. 



The Santa Ninfa nature reserve lies within the bigger Site of Importance to the Community called the “Complex of the Santa Ninfa and Gibellina Mountains and Santa Ninfa Grotta”, set up in 1998 for the presence of various natural habitats and species, in accordance with the EEC 92/43 Habitat directive. The protected area, which has a surface area of about 140 hectares, lies in the territory of Santa Ninfa and neighbouring Gibellina (both places are in Trapani province). At first sight the territory does not seem to contain any spectacular beauties. However, a closer look reveals an incredible number of beauty spots. In the course of time this area has not been greatly threatened by commercial or industrial settlement, and so it has particular integrity. Consequently there are micro-habitats of rare beauty and major scientific interest. The natural landscape is particularly variegated and sinuous for the presence of numerous “dolines”. These depressions in the territory, which are more or less circular in shape, are indeed the most evident geomorphological element: these natural concavities are very close to one another, and trace out scenarios that evoke fascinating beehive structures. The dolines are a sign of the presence of karst phenomena, linked to a set of physical-chemical dissolution processes caused by rainwater in soluble rocks, like chalks and limestones: the rainwater shapes the rock, giving rise to a fascinating visible landscape, and through cracks and pores infiltrates the subsoil, contributing to the formation of subterranean cavities. Among the many caves, the one that gives the name to the reserve is undoubtedly the most spectacular: getting into the hole in the rock leading into the cavity is a truly exciting experience. You can visit the cave with the necessary speleological equipment and accompanied by the local guides.

CASE STUDY: VILLA MARGHERITA



Castelvetrano is an Italian town of about 31,761 inhabitants. It is situated on the South-Western coast of  Sicily, in the province of Trapani.

BIO-GEOGRAPHICAL STUDY OF THE TERRITORY

The territory of Castelvetrano, geologically young, is made up of a monocline that gradually plunges towards the sea.  Its morphology is quite hilly with small slopes,  reaching a maximum of 290 metres above sea level  to the north of the inhabited area. The territory has plenty of water. The main streams ,that are typically torrential , are Belice, that gives its name to the Valley, Modione and Delia. Since the territory is an agricultural  area ,  the outskirts of the town are intensively cultivated . For this reason it is quite difficult to find natural sites with flora and fauna typical of the Mediterranean insular area. The most common cultivation is the olive tree  in its variety called  "Nocellara del Belice" used either as table olive or oil. The latter product  is recognized   as a PDO product and is well-appreciated both in Italy and abroad. Other agricultural products  are vineyards, vegetables and wheat. 


CASE STUDY: VILLA MARGHERITA
The site we have chosen as a case study for urban recovery is a small garden that overlooks Regina Margherita Square (37°67' North ,12°79' East) from which it takes its name, in the city centre and on the edge of the first historical nucleus.


Regina Margherita Villa occupies a triangular space between two churches, St. Dominic Church (the oldest of the town ,XVth century)  and St John Church ( XVIth  century ) . In 1871 trees, palms, rubber plants were planted. In 1885 it was embellished with an iron railing and in 1887  a sculptor from Palermo, Mario Rutelli, added a marble group in the centre of a fountain. Unfortunately, during the Second World War the original , iron railing was partially damaged in order to make some cannons , and during  the 1968 earthquake that  destroyed the Belice Valley, the garden was used as a shantytown for the homeless  . Rutelli sculpture was restored by Professor Benedetto Risalvato  and it was put at the entrance to the Selinus Theatre while a copy of it was located in its original place, these days vandalized and degraded. Our recovery project includes a botanical study to identify any problems with the trees ; an intervention on them to remove molds and other infections; cleaning of flower beds and restoration of the sculpture called  "Bambocciata". 

Images referring to the first site visit to Margherita Villa  that took place on 26th February, 2016  with the whole staff and with the expert in Forestry and Environmental Sciences, Doctor  Cirabisi.
