Near San Giacomo the Greenway crosses the road that leads from the town to Protte. Beyond the bridge over the Marroggia river the cycle path picks up again on the right, and runs along the left bank of the river to the overpass at the Campello sul Clitunno junction. Along the path, on the right, there is a small poplar forest: it dates back to 1950, and today it is an important refuge for numerous animal species. The Marroggia river begins to follow a more natural route at this point, and in the sections where the current is weaker you are likely to be able to pause and observe the elegant movements of dragonflies.
Further ahead, at the height of the water treatment centre, the Marroggia river flows away from the path, making way for a vast plain: at this point the river is joined by water from the Fosso Cortaccione drainage ditch and the Spoleto Valley Greenway intercepts the Lacus Clitorius Greenway. Moving on, enjoy the view over the Spoleto countryside, separated from the Valnerina valley by a section of the Apennine Mountains. At the first crossroads there is an old watermill on the left. The presence of an imposing weir gives pause for reflecting that the hand of man is forever attempting to contain and control the erosive force of flowing water. Downstream from here there is a large swathe of reed bed, a vital habitat where numerous species of birds, fish, reptiles and amphibians find refuge. Further on, the river starts flowing in a straight line again, in a single channel. The beautiful surrounding countryside is dotted with beautiful farmhouses and outbuildings, including old dovecotes, where the birds were reared in days gone by.
The ecological network
The Greenway Valle Spoletana partly corresponds to the ecological corridor of Tessino- Marroggia which represents, for animal species, an important connection between the Spoletan mountain-forest ecosystems and the wide alluvial plain of the Spoletan Valley, coincident with the basin of the ancient Lacus Clitorius. Near San Giacomo, the corridor Valle del Tessino – Valle del Marroggia joins the Greenway Lacus Clitorius that, thanks to its 15 km steadfst development between Passo d’Acera and Morgnano, connects Martani Mountains to the mountain systems between Spoleto and Trevi.
The reed bed
Walking along the Greenway, between San Giacomo and Azzano you’ll be able to observe a string of vegetation that stretches along Marroggia river. This semi-aquatic plant community is called reed and it is mainly made up of common reed (Phragmites australis). The reed bed represents a fundamental habitat of great conservation concern between land and water.Within reed beds live animal species that characterize both terrestrial and water environments, such as amphibians and birds, that there find the ideal conditions to find shelter, breed and feed.
