A space for previous reflection a. If you have heard of biodiversity before, you may briefly respond to these questions (read

them carefully and think before you respond):

Which of the following definitions of biodiversity is correct:

b. Some species were introduced into the native flora and fauna by accident and also deli-

berately, and in each case it was humans who introduced them. Which of these groups contains the names of invasive species only?

c. The concept of a green space in the urban world seems, in principal, to be a contradicti-

on as it is difficult to define it as natural. Why is it important nevertheless that cities have potent green spaces?

d. Biodiversity allows man to discover plants with a variety of qualities he can benefit from.

There are probably many species still unknown today that hold pleasant surprises for us, so do not ever believe that any species is useless. Keeping this in mind, which of the fo-llowing suggestions is correct?

The Importance of Biodiversity [1]

� The evolution of species and their appearance and disappearance throughout the his-tory of the earth.

� The wealth of species in an ecosystem and the relative abundance of individuals of each species.

� The number of animal and plant species that exist in an ecosystem.

� Sparrow / Chamaerops / Parrot parakeet.

� Earthworm / Common mouse / Pine

� Asian tiger mosquito / Monk parakeet / Ginkgo biloba

� In order to maintain urban biodiversity

� To maintain a good balance between day and night temperatures

� To improve air and life quality of the inhabitants

� Plants allow the production of many medecines

� Serve to limit the emergence of many harmful insect pests

� Serve to limit the emergence of many lichens

Possible transformation of the vegetal landscape in Barcelona

Vegetation of the Barcelona area at the time of the Iberians

At the time of the first Iberian settlements, oak forests that covered the plain of Barcelona be-gan to be eliminated. The Iberians were located in more elevated spaces, that is, in the hills and slopes of Collserola and Montjuïc, and gaps began to appear in the territory of the original vegetation.

Vegetation of the Barcelona area in Roman times

The city known as Barcino was established at the mountain Tàber. There, public green spaces were limited to some trees and shrubs. In the private sphere, however, gardens with edible and medicinal plants could be found, as well as fruit trees and ornamental plants. The first green space created in Barcino was the legendary Hort del Paradís, Paradise Garden, the hanging gar-dens at the carrer del Paradís.

Vegetation in the Barcelona area in Medieval times

Count Mir constructed the Rec Comtal or Rec d’en Mir, which took the Besòs waters to Montca-da, brought them to the city and emptied them at the port, a distance of 12km, passing thro-ugh Sant Andreu and Sant Martí de Provençals. It served to move the mills and irrigate the land. Its existence changed the territory, since the space between the Rec and the sea became a fer-tile garden, which was named the garden of Barcelona in the 14th century. The predominance of agriculture as a defining feature of Barcelonan territory began at the end of the 8th century and finished in the middle of the 19th century. It was in the beginning of the 8th century that the area became organized in farms, crops, pastures and forests, when irriga-tion was intensified. The vegetation itself.: Some houses had gardens with ornamental plants, gardens with producti-ve nature, vegetables and fruits, which were intensely cultivated. The orchard was a type of garden dedicated primarily to consumption. Institutions had orange courtyards or groves. Their purpose was more ornamental and sensual, and served as a sign of prestige. The Barcelonan orange courtyards are considered characteris-tic of the medieval gardening tradition of our city, which originate in the Hispanic-Muslim tradi-tion. (Orange courtyard of the Llotja Gòtica 1401, Orange garden of the Casa de la Ciutat, Orange courtyard of the General Council 1536, the Casa de les Comèdies at La Rambla which disappeared in 1775)

Vegetation in the Barcelona area from the 18th to the middle of the 19th cen-tury. A Barcelona that is still primarily rural.

The rural landscape basically remained until the the mid-19th century. Until then, the area was primarily agricultural and without a lot of buildings. This area was marked by its military conditi-ons, which hindered further development. In the 18th century, agriculture in the Barcelona area was flourishing and numerous new residen-ces and farm houses were built. The most important novelty was probably of industrial nature (calico fabrics) that required white-ning. They had to be in flat and sunny places, where water was abundant, which is why the area became known as the Indiana prairies. The Indiana prairies The Indiana prairies radically changed the landscape of some parts of the Barcelona area. They were at the Raval, close to the Rec Com-tal, at the Parliament and at Sant Martí de Provençals. Thus the walled city, already industrial insi-de but still rural on the outskirts, dotted the landscape of the surroundings with its intense mani-facture of Indian fabrics. In the villages of Sarrià, Pedralbes and Gràcia, towers surrounded by gardens began to appear.

Barcelona today

In the mid-19th century changes were initiated that radically changed the Barcelona area in irreversible ways. These changes would represent the end of rural Barcelona and the beginning of urban BCN. The walls were demolished. The area that used to be agricultural and without many buildings was now under construction. The last major deforrestation of Collserola took place during the Civil War and in the immediate postwar period when, due to lack of fuel and oak, pine and white pine we-re reduced. It mainly affected the way the sun entered into the city, as shady places were less accessible now.

The Green World refers to the structure of the urban scheme located over the natural soil. Its wealth and health is an indicator of the environmental quality of the city. It contains natural spaces more or less transformed and completely artificial spaces (urban parks and gardens). In the city of Barcelona we find: hill environment (peripheral area of the city / parks at the Collserola side), streets framed with trees, urban parks and gardens, a zoo, and forest and moorland sites. The urban stretch is usually a result of urban planning, conservation or both. In contrast, the fauna is usually established in a natural way, in areas that are favorable to their development. A concrete case is the cuallevat ant (Crematogaster scutellaris) that lives in trees with aphid, its power source. 3.1 Indicate the colors of the different body parts of the cuallevat ant (Crematogaster scutellaris) that you observed Head: Body: Abdomen:

Barcelona has a cosmopolitan wildlife [7] There are many species in the city of Barcelona, both invertebrates (insects, worms, spiders...) and vertebrates (reptiles, amphibians, birds, mammals and fish). The vertebrate wildlife is generally characterized by its commensalism and philantropy. Most benefit from the absence of natural predators, of the relative prosperity and thermal stability of the urban structure and the high prouction of waste and biomass associated with invertebra-te animals. The reintroduction of the peregrine falcon, a small step towards the naturalization of the city A few decades ago you could find peregrine falcons nesting on the Santa Maria del Mar, until the urban riots set in, and human interests caused the extinction of even the last couple. Nevertheless, they could make use of new vertical structures (skyscrapers). It is not surprising that while the common hawk disappeard from natural areas like the Montseny, where the last nest was abandoned in 1982 because of the great amount of visitors, it can be found in areas closer to the Barcelonan population, yet in more peaceful pla-ces like the Banc Atlàntic skyscraper. In Catalonia, the falcon is a sedentary species, even though during the winter, some individuals come from Central and Northern Europe. In May 1999, four nests were placed on top of tall buil-dings in the city and 15 chicks born in captivity placed inside. This project promoted wildlife biodiversity and a reevaluation of the natural heritage of the city of Barcelona, as well as helped control the local pigeon population, which formed part of the falcon’s urban diet. There are currently three pairs of breeding falcons in Barcelona and one other in Sant Adrià del Besòs (www.falconsbarcelona.net) Problematic species These are species that were able to change their diet and benefit from the abundant food sour-ces in Barcelona. Pigeons. 180.000 were counted in 1992. They erode the walls of buildings, street furniture and transmit diseases. Since 1983 annual catching and gasification campains were carried out in various black spots of the city. The reason why the birds are so successful is that citizens conti-nue to give them food. In various European cities, awareness rising campaigns have been carri-ed out with great success. Grey rats, adapted to living in the sewers where they feed on human waste. Gull. Began to arrive inside the city of Barcelona beginning in 1972. The gull is increasing dra-matically in recent years throughout the Catalonian coast, primarily due to the control of cap-tured eggs, the increase of human waste and the new capacity of that species to benefit from the given resources. Not being selective and eating nearly anything has proven successful in this area ; they were thus able to change their eating habits and went from eating only fish to omni-vorism, using human waste, especially from landfills. They even attack pigeons in order to com-plement their nutrition.

Exotic species Lizards native to the islands (Ibiza, Formentera, neighboring islands), were found in the area of the Glòries plaza. It is assumed that they were introduced deliberatly around 15 years ago and continued to survive in an area of barren slopes with rocks and abundant vegetation availa-ble (Llorente,G. Et al.1995). It is possible that this community is endangered by urban pressure.

Monk Parakeet. After a massive import of these birds, they became caged domestic animals in many Barcelonan homes, but a large number of individu-als that were captured were also subsequently rele-ased. We can highlight three species here: the Monk Parakeet (Myopsitta monachus), the Rose-ringed Parakeet (Psittacula krameri) and the Blue-crowned Parakeet (Aratinga acuicaudata), the first of which was able to integrate in the urban dynamics of the city the most (Batllori,1985). The population of the Monk Parakeet is five tiems bigger than that of the Rose-ringed Parakeet. One of the keys to being a successful colonizer is the construction of large communal nests used both to rest and reproduce (Senar,1991).

The first nesting was found in Barcelona in 1974 in the date palm cemetery of Poblenou. Later on it continued in garden areas around the town and nearby municipalities. In 1991, there was a leak of copies that had just been delivered to the port, which brought new individuals to tho-se colonies that were beginning to form. Although these species can build their nests in different types of trees, it seems as though there is a strong preference for palms. The spread of palm trees enframing roads and alleys has en-couraged a further development of the community. These species have caused trouble in their place of origin (South America) around cereal crops, rice and citrus (Freeland, 1973). Problems have also been described in urban areas, such as the degradation of vegetation in urban parks and gardens, the transmission of diseass, the degrada-tion of urban furniture and nuisance for the neighborhoods due to the ensuing noise.

4.1 How did the Monk Parakeet get to our region? What has been the key to success of the colonizer? What problems can these parakeets cause in

urban areas?
