and finally, those related to wetland areas (Fig. 8.7.15) that are mostly found
in the hill zone and along the coast, and therefore in the most settled areas.
The integration of the two interpretations (overall and limited to nodes/cor-
ridors) favors the design of the REM, which is configured as a base narrative
which deals with the entire territory, and is characterized according to its
eco-
logical functions
(Fig. 8.7.16). The elements constituting the network are dif-
fuse both within areas of great naturalness and within those more extensively
modified by anthropic processes. For example, near the capital of the region,
which is considered a coexistence of metropolitan and important natural areas
(such as the Conero Regional Park), almost all of the elements constituting the
network are in close proximity to one another (Fig. 8.7.17).
The perspective framework is arranged in three distinct parts: the first part
defines the measures to be adopted for the individual resources; the second
highlights urgencies and priorities at the territorial level; the third identifies
tools for activating the monitoring system at different levels.
Finally, to meet the objective of favoring the activation of the REM at the
local scale, 25 project investigations have been developed, which carry partic-
ular importance for the significantly urbanized areas. These are divided into
five emerging themes and contexts:
1. The coastal city and its residual
environmental relationships
with the
hills.
2. The settled valley floor, river connectivity, and green backbones.
3. The agrarian landscapes and the diffuse connectivity of inland areas.
4. The dilated Apennines: the transition between the ridges and the foothills.
5. The Apennine ridges and the connection between protected territories.
Within the case studies coming under theme 1, we have identified the
“Colline del Fermano” as a typical example. This is an area of strong commer-
cial productivity, morphologically distinct from the settled valley floor.
Whether on the crest of the hills or in the valley, a progressive joining togeth-
er of built areas is seen. The rural area of the remaining part of the territory
coexists with elements constituting the regional ecological network (Fig.
8.7.18). Strategic orientation primarily deals with interventions to reinforce
the connections between the components of the
river network
. Particular
attention is placed on the
residual internal areas
to counteract the risk of a
reduction in biopermeability. Vegetation formation is the object of particular
attention, above all when continuity could be lost by intersecting various infra-
structures (Fig. 8.7.19).
Within the case studies coming under theme 2, we have identified the floor
of the Tronto Valley as an example, which is characterized by the tight proces-
sion of natural and man-made components. The river corridor marks the south-
ern limit of building expansion, which in a longitudinal sense, tends toward
the progressive joining together of its parts, above all near the arteries of the
infrastructure. The vegetation formation of the hydrographical network and
the division of cultivation into farms, keeps the relationship between the river
and the rural and urban fabric alive (Fig. 8.7.20). From the strategic point of
