Camí natural d’Utxesa

The River Segre and Utxesa Nature Trail begins at Torres de Segre (El Segrià - Spain), which is 15 km from Lleida (Spain). It connects a section of the river Segre with the Utxesa reservoir and surrounding area. The total length of the route is 13.5 km and it almost the whole route is in the municipal district of Torres de Segre though near Utxesa it also passes through part of the municipal district of Aitona.

On account of its natural value, Utxesa has been included in the Pla d'Espais d'Interès Natural (PEIN - Plan for Places of Natural Interest) and in Xarxa Natura 2000(Nature 2000 Network) in the section for the Drylands of Segrià-Garrigues. It has also been catalogued as a Zona d'Especial Protecció per les Aus (ZEPA - Special Protection Area for Birds).

There are also plans to include the section of the river Segre that passes through Torres de Segre whenXarxa Natura 2000 is extended.

The PEIN of Utxesa includes parts of the municipal districts of Torres de Segre, Aitona and Sarroca de Lleida. It is formed by the reservoirs of Utxesa-Secà, Simó and Burgebut, with their respective tail ends as humid zones; and also includes the tablelands of the Tossal de Carrassumada and the Tossals de Sunyer as wilderness areas.

All along the River Segre and Utxesa Nature Trail it is possible to enjoy a wide variety of landscapes where visitors will find numerous plant and animal species and a particularly large number of birds.  

Natural values

Along this section of the river Segre it is possible to enjoy really gratifying natural scenery as well as viewing the landscapes of the orchards and market gardens of the municipal district of Torres de Segre. The area bordering the river Segre has all of the typical vegetation associated with riversides. Local species include poplars (Populus nigra and Populus alba) and "verns" (Alnus glutinosa) There is also a great variety of fauna, including water fowl such as the mallard (Anas platyrhynchos), moorhen (Gallinula chloropus), grey heron (Ardea cinerea) and little egret (Egretta garcetta).

As well as water birds, near the river it is also easy to see the white stork, because there is a colony of them nesting on the bell tower of the local church and they often go near the river in search of food.

The Utxesa-Secà reservoir is a truly unique natural space, which is located at the very south-western tip of the central Catalan plain. It is a confluence of natural systems with a rich diversity of flora, vegetation and fauna. The diversity of its bird species (there are more than 280) led to it being declared a Natural Wildlife Reserve.

The most typical bird species found in the area include the marsh harrier (Circus aeruginosus), grey heron (Ardea cinerea), purple heron (Ardea purpurea), cormorant (Phalacrocorax carbo) and coot (Fulica atra).

As well as including the important wetland zone of the Central Depression, the area also includes tubular relief and quite important expanses of arid landscape. Some of the vegetable species that can be found on these low ridges include: thickets of rosemary and "maleïda perdiguera" (Rosmarino officinalis-Linetum suffructicosi) amongst which it is important to highlight a variety that is endemic to the Iberian Peninsula, "astragal de narbona" (Astragalus turolensis). Other varieties include dry thyme (Sideretum cavanillesii), alfa grass (Lygeum spartum), "sanadelles" (Stipa offneri, Stipa parviflora) and other herbaceous vegetation and particularly greybeard (Brachypodium retusum).

These types of vegetation also contribute to the presence of sub-steppe species such as the lesser grey shrike (Lanius minor), roller (Coracias garrulus), Thekla-Lark (Gaderida theklae) and the calandra lark (Melanocorypha calandra).

Cultural values

  • The Parish Church of Torres de Segre. The Parròquia de la Mare de deu Assumpta de Torres de Segre has been declared a cultural item of local interest. This church was built in the mid-18th century (1749-1759) and is an example of the classic church building typology, with a basilica-style layout, a transept and crossing dome, and baroque-style circles, which can be found in many parts of western Catalonia.
  • Hermitage of Carrassumada . The Ermita de Carrassumada is located on top of a small hillock and is a few kilometres from the centre of Torres de Segre. The site is the property of the Bishopric of Lleida. From the top of the hill it is possible to enjoy an excellent view over most of the comarca (local district) of El Segrià. There are still clear reminders of the original settlers who inhabited this hillock back in the Iber period. However, the name of this temple is the result of six centuries of Arabic settlement and culture.Carrassumada, or Kars'umm-adà in Arabic, is a composite term formed by Kars (palace or castle), Umm (mother) and adà, the name of the most important lord or master. It therefore would seem to mean: The Palace of Adà`s Mother. When the Christians reoccupied this area, in about the 12th century, they probably dedicated this hill to Saint Mary, crowning it with a small church built next to the palace and with the former mosque becoming part of the Christian temple.
  • Archaeological remains. The best known ancient settlement in this area is the one located at the tossal dels moros (Moor's Mound). The period for which there is most information about this mound is that of the medieval Moorish occupation, in which a small hamlet was built, which was surrounded by a wall and called Borch - Aisa. Archaeological remains have also been found on the hillock called Solibernat, which is very close to thetossal de Carrassumada (Carrassumada hillock).
  • Vaulted structures. These constructions are typical of this area and can be found near the Utxesa reservoir. They are buildings with relatively simple characteristics that were built by farmers to provide places in which to shelter from the rain and where they could let their animals rest.
  • Solution pits. Cadolles (solution pits) are natural holes that appear on the tops of flat rocks where rainwater accumulates and forms a small pool. They are mainly circular. In some places there is evidence that they have been extended by human agents in order to store larger quantities of water.
