L.R. no. 5 of 28th February 2005
The Reserve develops within Oropa Basin from an altitude of 814 meters
to the summit of the surrounding mountains reaching the 2,400 meters
above sea level. The slopes of Mt. Mucrone, Mt. Camino and Mt. Rosso
are covered in their highest stretches with large grasslands consisting
of nards, shrub formations with Green Alder and Rhododendron. While
going towards the bottom of the valley, these formations alternate with
invasive Birch in the abandoned meadows and grazing lands; the area of
the Sanctuary and Sacred Mountain is surrounded by forest formations
dominated by Beech tree - sometimes pure, but usually mixed with
Sycamore Maple and Ash tree at lower altitudes and with Golden Chain
tree and Mountain Ash at higher altitudes. Locally, between the 1,600
and 1,700 meters, there are populations of Bog Pine introduced by man.
Recent floristic research has given the opportunity to determine that
in Oropa basin there are almost 800 species, a very high number given
by the variety of the existing environments.
The establishment of Riserva naturale speciale del Sacro Monte di Oropa must be considered an integral part of the conservation and enhancement
project started by Regione Valle d'Aosta with the establishment of Riserva naturale regionale del Monte Mars in 1993; this action is part of the project of the National Ecological
Network activated by the Italian Department of the Environment in 1999,
according to which it is necessary to create an alpine territorial
system where it is possible to direct integrated and total policies
aimed at the conservation and enhancement of the natural resources and
system strategies regarding all the local environmental and cultural
elements. The system consisting of the two Protected Areas involves the
territorial and landscape context where the ancient procession held
every 5 years from Fontainemore to Oropa develops.

Analyzing the landscape of the Sacred Mountain, it is interesting to notice how vegetation represents an occasion to discover one of the integral parts of the sacred architectural project, although not the priority. The area of Mt. Oretto (that's the name of the mountain where the chapels lie) has been characterized by forest and animal breeding activities: the lower part was used as a pasture, the upper part as a forest, mainly a beech tree forest.
