Abstract
The protected areas are those territories subordinates to a special program of protection and management, in which is present a natural and cultural patrimony of important value.
In the present job the planning of the Natural Reserve of Tuscania, (country of Viterbo, north
Lazio), has been considered with objects of conservation of the environmental values and
sustainable economic development, like disposed of law L.R. 29 of 1997. The challenge is to
promote in the protected areas an economic development and in the same time conservation of the rhythms and the values of the nature.
We examined the state of the flora and the fauna present in the Reserve, the physical
atmosphere and archaeology, the state of the historical center (that is inside of the Reserve), and the impacts of the agricultural activity and the anthropic activities present, trying to arrive to a zonation
of the Reserve who respect the vocation of the territory.
The involvement of the Pubblic Agencies for the realization of the plan in order of the Natural
Reserve of Tuscania, has been continuous and constructive and has seen in the office of the park (instituted towards the end of 2004), a point of reference for all the citizens of Tuscania and not only. Therefore, task of the sustainable management is to regulation the use of the ecosystems and
the resources on levels that are tolerable from the system and that respect the resources to our
disposition.
For the Natural Reserve of Tuscania it has been predisposed a SIT-GIS in order to manage all
the informations that have been collections in the phase of surveying of the scientific study, in order to define the vocations, analyzing all the characterizing aspects of the territory of the natural area, perceiving it not like a geographic part but inserting in the immensest concept than intercomunale,
provincial, regional and national planning.
The fundamental role of the zonation is therefore to guarantee the conservation of the values of the territory being assigned various ties of protection to the various zones.
The study has evidenced the vocation of the Natural Reserve of Tuscania (RNT), that it is of
"rural park", that sees in the cultural landscape, that is historically influenced from the man, the main peculiarity.
To this joins the vocation "to archaeological park", like an important Etruscan center.
From the study it is emerged that to the center of the problematic is the Marta river, that slides in the heart of the Reserve from north to south.
The Marta is disturbed from the regulation of the lago of Bolsena (floodgates to the incile),
from hydroelectric centers of ENEL, that they interrupt for long and numerous features the uppermiddle course of the Marta river.
The quality of waters is modest, with repercussions on the microfauna (index IBE) that on the fish. To weight down the cargo on the river there is also one paper factory and the communal water conditioner for the civil drainages and also black waters of the slaughterhouse.
As far as the diffused sources of agricultural pollution, the problem does not appear of extreme
urgency, if not other compared with the other pollution sources; can some deduce therefore, that the agricultural activities presents today to the category of the compatible ones, in the sense that attributes to such term the law 394/1991 and L.R. 29/1997 (art. 26).
But the norm, too much addressed towards a zonation reported nearly exclusively on the rate
urbanization of the territory, has rendered enough difficult the task of allocation of the zones and subzones to the RNT. The dispositions to respect derive: of the institutive regional law n. 29/97, of the guide line of the Lazio Region and the outline standard of the Region.
The fundamental problem of the zonation is that easy falling in one clean separation between
the habitats.
To such scope, the Plan in Order proposes an Agenda 21 in order to allow to the local agencies
of being able to manage in compatible way the environmental system through one local politicy that has like common objective a sustainable development.
Today the restrictions dictated of the safeguard norms, limit seriously the development of
Tuscania. That makes to perceive the Reserve like a bureaucratic agency, a subject bound the
development of the territory.
For such reasons hope a quick approval of the PdA from part of the Country of Viterbo and the
Lazio Region, so as to be able to allow the RNT to develop a sustainable development for the
territory.
