But what is a lagoon?
A lagoon is a transitional aquatic environment where freshwater from rivers and streams meets the salty waters of the sea. It is a vital ecosystem for biodiversity, home to a rich variety of plant and animal species. However, its ecological balance is delicate and requires care and respect.

In these calm waters, ducks, herons, egrets, and rare gulls thrive, immersed in the scents of Mediterranean vegetation and the vibrant colors of samphire. As long as nutrient-rich, unpolluted freshwater continues to blend with seawater in the lagoons, they will remain invaluable habitats for biodiversity conservation.

Interweaving of water,
sea and land.
Lagoons shape the coastal landscape of all of Sardinia. Their waters are often murky, and if we were to taste them, we would notice that their salinity changes depending on the season.

Lagoons shape the coastal landscape of all of Sardinia. Their waters are often murky, and if we were to taste them, we would notice that their salinity changes depending on the season.
how does the lagoon change throughout the year?
In winter, the turbulent floods of the stream make the lagoon less salty and enrich it with essential nutrients for the life cycles of its inhabitants. In summer, however, salinity rises significantly due to the drying up of the Arrieras stream and intense evaporation caused by high temperature and strong sunlight. By August, the salinity of the Nora Lagoon is nearly 10 points higher than the one of the sea. Too salty even for cooking spaghetti!
The Lagoon, The Nursery of the Sea
Many fish species migrate from the open sea to lagoons to grow. The mullet, for example, reproduces in the sea, but its juveniles swim against the tidal current to return to the lagoon, where they find abundant plankton and shelter. Once they reach maturity, the mullets head back to the sea to reproduce, repeating the cycle. The strong attraction to the lagoon for fish born in the sea is driven by the abundance of food these environments provide. Lagoons are among the most productive ecosystems in nature, as the rivers that flow into them carry mineral salts washed from the land they pass through.
A GREEN WORLD IN THE BLUE
Plants use these “fertilizers,” along with solar energy, carbon dioxide and water, to grow and thrive.
Among the essential aquatic vegetation supporting life in lagoons there are microscopic floating algae, known as phytoplankton, and larger macroalgae, which are anchored to the seabed.
When algae die, they are colonized by microscopic organisms such as bacteria and fungi, which decompose them into detritus. As decomposition progresses, the detritus gradually breaks down, becoming food for millions of tiny organisms.
Larger animals feed directly on these small organisms, transferring energy through the food chain to increasingly larger species.
The lagoon birdlife
In the Nora Oasis, amidst green landscapes, the lagoon and the sea, a variety of bird species hover, rest during migration routes and nest.

Halophytic plants
Lagoons represent a challenging environment for vegetation, where plants must adapt to extreme conditions.


Halophytic plants
Lagoons represent a challenging environment for vegetation, where plants must adapt to extreme conditions.

WHAT CHARACTERISTICS DO HALOPHYTIC PLANTS HAVE?
Halophytic plants can tolerate high salt concentrations in the substrate thanks to evolutionary mechanisms that enable them to survive in this habitat. Halophytic plants (or halophytes) can withstand sodium chloride (NaCl) concentrations ranging from 2% to 6%, compared to the 0.5% tolerated by most plants. They have developed various mechanisms to absorb water and nutrients, including:
- Increase in the salt concentration of cell sap through the accumulation of sodium, chloride, and potassium. Salicornia, for example, has a naturally salty taste.
- Absorption of salts followed by the elimination of excess through secretory cells on stems and leaves, giving the plant a porcelain-like texture, as seen in Limonium.
- Salt exclusion mechanisms at the root system level, as seen in Artemisia.
WHICH HALOPHYTIC PLANTS LEAVE IN THE LAGOON?
Prominent among the lagoon flora is salicornia, which is extremely versatile due to its resistance to summer dryness and winter submersion. It forms extensive grasslands around lagoons, characterizing them with seasonal color changes: from green in spring to red in summer. Salicornets host other halophilous plants within them:
Inula, with its fleshy leaves and robust root system, maintains a deep green color until late summer, a time when it is adorned with vibrant yellow flowers. Obion, on the other hand, develops hairs on its leaves to remove excess salt. These dead hairs and the salt accumulated on the surface reflect solar radiation, reducing heat and limiting evaporation.
Alimo grows mainly in coastal areas exposed to winds. Its tender twigs, macerated in vinegar, are used as a condiment. Its flowering extends from July to October.
Limonium or Common Statice enriches the biodiversity of brackish wetlands, with flowering extending from July to October.
In the Nora Lagoon, one of the most significant endemics of Sardinian flora, Isabelle’s and Caroline’s Limonium (Limonium carisae Erben), is found, flowering from June to August, finding its exclusive habitat in the meadows along the banks of the lagoon channels.
The Habitat: Heritage
and Conservation
Laguna di Nora is located within the Special Conservation Zone (SCZ ITB042216) “Capo di Pula” and within the Wildlife Protection and Fishing Reserve “Santa Margherita-Nora” (L.R. 23/1998).

Laguna di Nora is located within the Special Conservation Zone (SCZ ITB042216) “Capo di Pula” and within the Wildlife Protection and Fishing Reserve “Santa Margherita-Nora” (L.R. 23/1998).
WHICH AREAS ARE INCLUDED IN THE SCZ AND THE WILDLIFE PROTECTION AND FISHING RESERVE?
The protected coastal area covers approximately 1,850 hectares, stretching from the mouth of the Rio Pula (Foxi Durci) to Porto Campana, between the municipalities of Pula and Domus de Maria. It is one of the most biodiverse areas in southern Sardinia and a prime example of the Sulcis biogeographical subregion. This fertile coastal strip is nourished by several streams and creeks, including the Rio Pula, Riu Arrieras, Riu s’Orecanu, Riu Mannu, Riu di Santa Margherita, and Riu di Chia. These waterways either flow directly into the sea or feed a network of coastal lagoons and ponds of high natural value. The SCZ “Capo di Pula” encompasses a diverse range of environmental systems: the marine ecosystem, the coastal wetland system at the mouth of the Riu Pula and the Laguna di Nora (Stangioni S. Efisio), the coastal stretch between Capo di Pula and the river mouth, and the insular ecosystem of San Macario. Although distinct, these ecosystems are closely interconnected.
RARE AND ENDANGERED SPECIES LEAVE ONLY HERE
Plants are important bioindicators of the natural characteristics and overall health of their environment. Fortunately, the Oasi is home to a rich variety of plant species that signal a well-preserved environment.
From a floristic point of view, the Nora Lagoon is a place of great conservation value due to the presence of rare and endemic plants of Sardinia. Among these, Isabelle and Caroline’s Limonium (Limonium carisae) is the most representative species, found exclusively in the Nora area. Other notable species include Pignatti’s Limonium (Limonium dubium), endemic to Sardinia, Corsica, and Sicily, Limonium with reticulate branches (Limonium retirameum), Speronella sarda (Delphinium longipes), Damigella glaucescente (Nigella arvensis subsp. glaucescens), and the Cressa (Cressa cretica), which is classified as threatened on national red lists.
The Nora Lagoon is a site that is regularly visited by numerous species of birds, aquatic and otherwise. The lagoon compartment thus constitutes, from a birding perspective, the most important area of the SAC.
WHY PROTECTing IT
he Standard Data Form of the ZSC lists 30 bird species of community interest (Article 4 of Directive 2009/147/EC). Among them, the Audouin’s Gull (Larus audouinii) is the most significant species from a conservation perspective. Since 1990, this species has regularly nested at the site, with populations exceeding 600 pairs in some years, making the Laguna di Nora one of the most important nesting sites at the national level.
Over the past 25 years, however, a distribution shift has occurred, leading to a numerical decline in its historic range, which includes Sardinia and Tuscany. Until 2012, colonies in these regions accounted for approximately 80% of the national population, but they have since decreased in favor of newly colonized areas, primarily along the Ionian coasts of Sicily and Apulia, as well as in Campania (Ientile et al., 2016; Liuzzi et al., 2023; Amadesi et al., 2023).
The ancient tale
of the Lagoon
Laguna di Nora has not always looked the way it does today. Until the 1950s, the area now occupied by the lagoon was covered by the sea, forming a wide natural gulf sheltered from the northern and western winds.

Nora, a roman city
Under Roman rule, beginning in 238 BC, Nora experienced its greatest development and splendor. Between the 2nd and 3rd centuries AD, the city expanded greatly, with a road system connecting it to agricultural and mining centers inland. Ships loaded with goods from Spain, Greece, southern Gaul, the Italian peninsula, and Africa arrived in the port of Nora. The Romans and Punics used materials extracted from the Tyrrhenian Bench, which forms the Fradis Minoris Peninsula, to build the city.
As evidence of these activities, a Roman cistern from the third century AD, probably used to collect water for mining, can still be seen on the bank of the lagoon.
