Greek Crops – Phrygana and Garrigue
Human motion, burning and destroying historical forests that after bordered the Mediterranean basin, has broken the pure setting past restore all through historical past. Deforestation, carried out with the goal of making house for farms and pastures, has triggered progressive desertification and impoverishment of the soils which, left uncovered, have additionally suffered harm from erosion. Beneath these circumstances, the event of arboreal species turns into increasingly inconceivable, whereas it’s somewhat new types of vegetation dominated by low shrubs and sub-shrubs which change the bushes which have a tendency to ascertain themselves. The degradation of the Mediterranean maquis provides rise to a kind of plant formation referred to as garrigue (from Provençal garrigue), dominated by shrubs, which is discontinuous and with huge open areas with outcropping rock, and phrygana, typical of the bottom resorts. extra arid. .
Phrygana and scrubland happen close to the ocean and within the inside, and the crops that make up every formation differ in line with substrate, altitude and phytogeographic zone. It’s not at all times straightforward to tell apart the 2 sorts of vegetation, which regularly steadily merge into each other, creating intermediate formations usually composed of species frequent to each habitats.
The crops that make up these phytocenoses current the most typical variations to conditions of aridity, comparable to sclerophyll, which makes it potential to restrict water loss by evaporation and transpiration, and microphyll, which is commonly accompanied by thorns and fragrant substances that discourage herbivores. Regardless of troublesome residing circumstances, these environments are dwelling to many species wealthy in flora, primarily annual herbaceous crops that flower in spring and die in summer season, or bulbous crops that handle to flower and survive due to their underground reserve organs. Among the many commonest plant households of scrubland and phrygana are Leguminosae, Euphorbiaceae, Labiatae, Compositae, Liliaceae and Orchidaceae. Though nearly all of the shrubby and suffruticous vegetation of the Mediterranean areas is of secondary origin (i.e. the results of anthropic motion on the unique forests), there are additionally explicit conditions by which these formations symbolize the very best stage of evolution of the native vegetation. . Their destruction results in the formation of dry lawns dominated by grasses and maintained on this state by grazing.
The caddisfly, or thorny scrubland, is a semi-natural biocenosis; that’s to say, a formation made up of spontaneous species that develop due to grazing and fires. It’s shaped by low, hemispherical, densely and tightly branched shrubs that attain a most top of fifty cm. The leaves are drought and grazing tolerant and usually deciduous in summer season. Huge, open, sunny areas with uncovered rock separate the shrubs, particularly in extraordinarily arid areas close to the coast. In the course of the summer season, essentially the most uncovered vegetative elements of the crops that inhabit this habitat dry out, giving the vegetation a attribute “burnt” look. This panorama, typical of nations dealing with the ocean, is a habitat of neighborhood curiosity. Probably the most attribute parts of its flora are Euphorbia acanthoclada, Genista acanthoclada, Sarcopoterium spinosum, Pistacia lentiscus, varied species of sage and cistus, herbaceous crops additionally current within the scrublands and quite a few species of orchids. Areas left free by shrubs are sometimes populated by bulbous crops comparable to Gynandriris sisyrinchium, and different herbaceous species with lovely flowers, comparable to Ranunculus asiaticus.
The garrigue is a discontinuous plant formation with huge open areas between the crops; it’s characterised by evergreen shrubs and subshrubs that develop to a most of 1 m and are sometimes thorny and proof against grazing. In coastal scrubland, which lies on the border between coastal plant formations and habitats extra protected against the motion of the ocean, there are various species of the genus Helichrysum, the most typical of which is H. italicum. It’s usually accompanied by Anthyllis hermanniae and many alternative cistus, comparable to Cistus monspeliensis, C. salviifohus and C. incanus subsp. creticus, which colour the earth with their flowers starting from white to pink and yellow.
Totally different garrigue formations are dominated by completely different crops, for instance Euphorbia acanthoclada, Phlomis fruticosa or Salvia triloba. Along with the populations of Daphne sericea and Lavandula stoechas, these are habitats of Neighborhood curiosity and subsequently topic to particular conservation measures, as are all of the coastal plant formations containing associations of the crops talked about above. -above.
Annual and bulbous crops populate the open areas of the scrubland. All of those crops flower early, often across the time of the spring rains, when the temperature begins to rise above the winter common. These meadows are dwelling to many ephemeral species that however supply their colourful contribution to the celebration of spring: amongst these, the very aromatic asphodels and plenty of bulbous crops, such because the showy orchids of the genera Ophrys and Orchis.
Because of the explicit morphology of the flowers of orchids, we most popular to precede the descriptions of the person species with temporary introductions to the household and particularly to the genera Ophrys, Orchis and Serapias.
