City Urban Planningo of Sasso Marconi – Italy

Landscape, ecological network, and natural systems

The goal was to understand the level of ecological fragmentation in the area and the contribution that each part of the landscape already makes and could make to preserving biodiversity and building an ecological network on a municipal level. To these ends, natural, semi-natural, and landscape-environmental elements were evaluated in terms of the ecosystem. This was the basis for:
1.Defining the structure of the existing ecosystem
2.Identifying existing or potential conditions or influential factors on the flora, fauna, and landscape, and in terms of the area’s ecological fragmentation
3.Identifying model ecological scenarios
4.Preparing a preliminary ecological network plan
5.Comparison between the ecological network proposal and other siting and infrastructure arrangements that are already there or slated in the planning tools
6.Identifying critical points
7.Preparing a final version of ecological network plan

Based on local planning rules, land management, based on boosting the local ecological network, was divided into conservation, improvement, and completion.
Ecological studies that led to the design of the local ecological network pointed to the major ecological critical points as being in the Setta and Reno valleys. The same local ecological network holds most of the planned “works for completion”.
A planning chart was prepared identifying targeted, detailed needs for priority action, in addition to “work type summaries”.
1.Agro-ecosystems to which ecological balance functions should be given
2.Forest ecosystem to which to give ecological balance functions
3.Minor river corridors to be reinforced
4.River swath to bolster with multi-functional ecological functions
5.Openings of ecological permeability to be strengthened
6.Areas of ecological redevelopment with spaces for recreational use
7.Problematic development fronts to buffer with filter ecosystems
8.Potential barrier crossings
