139 - Menàrguens

Itinerari de 1.140 metres de llargada i 10 seccions, situat en una zona agrícola molt representativa del pla de Lleida. Situat a la comarca de la Noguera, a una alçada de 225 metres, es realitza des de l’any 2015.

El recorregut mostreja conreus abandonats, comunitats ruderals de la terra baixa, fruiterars i comunitats més naturals d'ambients molt àrids, com ara timonedes i prats de teròfits. Les condicions d'aridesa i calor extrema al període estival condicionen fortament la comunitat de papallones.

Phenology

The bars show the weekly average butterfly abundance (calculated as the number of specimens per 1000 m) for the set of species recorded in the transect. Dots correspond to the weekly average number of species.

Habitats

The graph shows the relative cover of each habitat type in the whole transect. Since 2000, a botanical characterization has been performed for each itinerary every six years. For itineraries with more than one botanical characterization, you can change from one to another by clicking on the year of characterization.

Sections

The map shows the transect route and the layout of the different sections. The background photograph corresponds to the 1:5000 orthophoto from the Cartographic Institute of Catalonia (ICGC).
