Itinerari situat al voltant de la Torre Salvana, al terme municipal de Santa Coloma de Cervelló, a la comarca del Baix Llobregat. Té una longitud total de 747 metres dividits en 8 seccions, a una alçada mitjana de 30 metres. Es va incorporar a la xarxa del CBMS l'any 2023, i va estar actiu fins el 2024.
La secció 1 recorre un sender obert i molt asoleiat, amb vegetació ruderal i alguns arbres a banda i banda (a destacar garrofers, lletsó, malva, caps blancs, panical i card marià -aquests just al final del transecte). La secció 2 transcorre per bosc obert amb pins i llentiscle. Als voltants, tot i que no són evidents si no et desvies del sender, podem trobar tambe cirerers d'arboç. La densitat d'arbres al voltant fa que mantingui una certa humitat fins i tot a l'estiu.

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.
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.
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).
