differences that characterize the two sides of Asinara Island result in a high variety of macro and micro habitats, which is reflected in the associated biological component.<\/div>\n<div>In particular, the limited depth and slope of the eastern seabed and the meteo-marine characteristics of this slope favor the development of extensive and well-structured <em>Posidonia oceanica<\/em> meadows, which are the typical elements of this part of the island.<\/div>\n<div> <\/div>\n<div>Posidonia is a plant endemic to the Mediterranean Sea, consisting of long ribbon-like leaves gathered in bundles. The young, central leaves are characterized by a light green coloration, while the older leaves take on dark green and brownish shades. The rhizomes are deeply intertwined and form special structures called <em>matte<\/em>, which may exhibit by the effect of current, channels and other special morphologies. In this way, seagrasses present a key role against coastal erosion by stabilizing the inconsistent seabed and limiting wave action through the leaf apparatus and the barrier effect of <em>matte<\/em>.<\/div>\n<div>The size and structure of posidonia beds are considered indicators of the quality of coastal systems because of their sensitivity to impacts generated by various anthropogenic activities (pollution, coastal erosion, increased turbidity, mechanical action due to fishing and anchoring).<\/div>\n<div>Grasslands represent biocoenoses with high biodiversity, in which various benthic and nectonic species, including some of considerable economic and naturalistic interest, feed, grow and reproduce.<\/div>\n<div>At the rhizome level, communities typical of deeper environments can be found, most frequently encountering holothurians, sea stars and the bivalve <em>Pinna nobilis<\/em> (a species of community interest and the subject of specific studies by the Park). Communities framed in the pre-coralligenic are established near the lower prairie boundary. As for the associated ichthyofauna, several species can be found, including seahorses, pipefish, wrasses, bream, salps, bream, bogue, and mullet.<\/div>\n<div>In terms of distribution, the prairie shows a considerable extension in the area between the Rada dei Fornelli and Punta Sabina, up to the bathymetry of about 35 m for an area of about 15 square kilometers, representing one of the most important posidonia in the Mediterranean basin. On the western slope, posidonia is locally present between Punta Tumbarino and Porto Manno della Reale to a maximum depth of 30-40 m.<\/div>\n<div>The grassland appears to be in excellent condition overall and does not generally show signs of obvious degradation, although there is evidence in portions, albeit spatially limited, of regression due to over-anchoring and areas where trawl furrows can be seen.<\/div>\n<div>The general state of well-being of posidonia meadows in Asinara is also evidenced by the analysis of its structure, the periodic presence of flowers and fruits, and the high values of leaf density.<\/div>\n<div> <\/div>\n<div>Species of particular naturalistic significance are found on the island: the red seaweed <em>Lithophyllum lichenoides<\/em> and the giant limpet <em>Patella ferruginea<\/em>. The former, included in the red list of species to be protected, is in steep decline in many areas of the Mediterranean being remarkably sensitive to pollution. <em>Patella ferruginea<\/em> is also a highly threatened species, mainly due to excessive anthropogenic harvesting. Here the stands of <em>Patella ferruginea<\/em> are found to be in good condition and often composed of individuals of considerable size (up to 10 cm wide).<\/div>\n<div>Surveys in the Punta dello Scorno area have shown at depths greater than 70 m a stand of <em>Laminaria rodriguezii<\/em>, a rare Mediterranean paleoendemism with considerable economic importance as a habitat for numerous species of commercial interest.<\/div>\n<div> <\/div>\n<div>The animal species found along the rocky seabed are those typical of reefs.<\/div>\n<div>Among them, some play a special role in fishing activities, as in the case of corvina, snapper, bream, sea bass, redfish, and several species of wrasses. The lobster<em>(Palinurus elephas<\/em>) can be found in the adult phase at depths between 15 and 100 m in rocky ravines and at shallower depths in the juvenile phase, during which it can also be observed in posidonia meadows.<\/div>\n<div>The presence, along the northern coast, of sizeable specimens of brown grouper has also been found at shallower depths than those at which these organisms can be observed in unprotected areas. Also of significance is the presence of the sea grasshopper or magnosa<em>(Scyllarides latus<\/em>), which has been listed as a species to be protected because it is highly threatened by indiscriminate harvesting. The presence of these and other species, such as moray eels, conger eels, and octopuses, in relatively abundant and undisturbed populations, as well as the variety and richness of benthic communities, certainly constitute reasons for the enhancement of the island&#8217;s seabed, but also a significant potential for sustainable enjoyment of the underwater environment.<\/div>\n<div>Finally, the presence in the waters facing the island of Asinara of bottlenose dolphins and other cetaceans, including minke whales and sperm whales, should be noted, which has resulted in the inclusion of the Asinara Sea within the international project for the conservation of the pelagic fauna of the Mediterranean, called the <em>Cetacean Sanctuary<\/em>.<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<div class=\"elementor-element elementor-element-06a8569 elementor-widget elementor-widget-spacer\" data-id=\"06a8569\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.20.0 - 13-03-2024 *\/\n.elementor-column .elementor-spacer-inner{height:var(--spacer-size)}.e-con{--container-widget-width:100%}.e-con-inner>.elementor-widget-spacer,.e-con>.elementor-widget-spacer{width:var(--container-widget-width,var(--spacer-size));--align-self:var(--container-widget-align-self,initial);--flex-shrink:0}.e-con-inner>.elementor-widget-spacer>.elementor-widget-container,.e-con>.elementor-widget-spacer>.elementor-widget-container{height:100%;width:100%}.e-con-inner>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer,.e-con>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer{height:100%}.e-con-inner>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer>.elementor-spacer-inner,.e-con>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer>.elementor-spacer-inner{height:var(--container-widget-height,var(--spacer-size))}.e-con-inner>.elementor-widget-spacer.elementor-widget-empty,.e-con>.elementor-widget-spacer.elementor-widget-empty{position:relative;min-height:22px;min-width:22px}.e-con-inner>.elementor-widget-spacer.elementor-widget-empty .elementor-widget-empty-icon,.e-con>.elementor-widget-spacer.elementor-widget-empty .elementor-widget-empty-icon{position:absolute;top:0;bottom:0;left:0;right:0;margin:auto;padding:0;width:22px;height:22px}<\/style>\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-68c1269 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"68c1269\" data-element_type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-78ce97f\" data-id=\"78ce97f\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-090f603 elementor-widget elementor-widget-text-editor\" data-id=\"090f603\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>For Asinara, the marine environment constitutes an element of particular value and scientific interest and is substantially characterized by a high integrity and diversity of floro-faunal communities, a remarkable landscape value, and excellent water quality in terms of ecology and chemical contamination.<\/p>\n<h4>The movements of the sea<\/h4>\n<p>Along the western side of the island, the surface circulation exhibits a marked seasonality: during winter the currents have a northeast to southwest direction and carry water masses from the west coast of Corsica, while in summer their motion is reversed. Within the Gulf of Asinara, the currents tend to move according to an hourly circulation that appears most pronounced in westerly winds, and to arrange themselves parallel to the coastline, particularly in the marine belt close to the shore. In the presence of southwesterly winds, the currents near the coast have a significant component in a direction perpendicular to it toward the open sea, resulting in vertical water movement of the deeper waters of the gulf.<br \/>The data collected by the Air Force over the course of 32 years from the station located near Punta Scorno, although referring to a period that is not recent, allow us to define a general picture of the state of the sea on the island of Asinara.<br \/>According to these data, the sea at Asinara is nearly calm on 20 percent of days and slightly rough one day out of two. However, for 25 percent of the days the sea \u00e0 very rough. During the period between May and September, sea conditions appear more favorable for navigation (particularly in the summer months), while the winter months are characterized by more severe sea states.<br \/>By virtue of the considerable exposure to westerly and northwesterly winds, the seas on the western side and northern cape of the island occur more frequently in states that are not favorable for navigation. The eastern side of the island, facing the Gulf of Asinara, is more protected and accessible, here are located the landing points among which the Reale pier is the least exposed to easterly winds. At present, the marinas of Cala d&#8217;Oliva and Fornelli, although sheltered from westerly winds, suffer most from exposure to easterly and sirocco winds.<br \/>Within the gulf, based on maximum wave height data recorded by the oceanographic buoy located in the Gulf of Asinara at Porto Torres during June 2000 to April 2001, waves rarely exceed one meter.<\/p>\n<h4>Water quality<\/h4>\n<p>The waters surrounding the island of Asinara are generally of high quality, as indicated by the remarkable transparency and low concentrations of anthropogenic impact indicator compounds or elements, to which corresponds a remarkable integrity of biological communities.<br \/>In the summer period, the water column appears vertically stratified, with maximum temperature differences of about 6 \u00b0C and surface temperature reaching as high as 26 \u00b0C in August. In winter the opposite process takes place, with a water temperature of 17\u00b0C in December.<br \/>Similarly, salinity, which, however, has a more limited time range, increases its values in summer.<br \/>In summer, the value of dissolved oxygen in the water also increases: this enrichment is probably related to the metabolism of the posidonia prairie that can provide the system with a large supply in terms of oxygen, which due to summer thermal stratification remains more localized on the bottom.<br \/>The trophic state of the water, measured by the combination of some parameters (chlorophyll, dissolved oxygen, total phosphorus and dissolved inorganic nitrogen), indicates high water quality and absence of significant alterations.<\/p>\n<h4>The morphology of the seabed<\/h4>\n<p>The seabed on the two sides of the island has profoundly different characteristics.<br \/>The open sea side is characterized by slopes with considerable steepness that continue in the submerged part and rapidly sink more than 50 m even a short distance from the coast. Strong currents and considerable mistral wave action prevent the formation of significant sandy deposits and shape the coastline with ravines, gullies and rifts. A cave of significant size is located at Cala di Peppe, set at sea level at a depth of about 8 m and a height at the entrance of about 10 m.<br \/>The eastern side is generally characterized by low, mostly rocky and sometimes entirely sandy coastlines. The seabed toward the gulf, taking up the morphology of the emerged part, tends to slope gently to the typical average depth of the Gulf of Asinara, which is about 50 meters.<br \/>The area between Punta Scorno and Punta Sabina has intermediate characteristics between those typical of the two slopes. The sea floor appears uneven as a result of frequent outcropping of the rocky substrate.<br \/>In the area between Cala d&#8217;Oliva and Punta Trabuccato, and particularly in the Rada della Reale, the seabed is predominantly sandy and hosts extensive and intact <em>Posidonia oceanica<\/em> meadows. Further offshore, around the 50 m bathymetric, the substrate consists of sediment and organogenic detritus.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element
