The classification of a Monumental Tree can take place if at least one of the following requirements is met:
- Age: the longevity of the plant is a significant element
- Dimensions: Very large size for the species or larger than the other individuals of the same species present in the examined area
- Particular shape or bearing: Unusual shape or bearing for the species
- Ecological value: this is the case, for example, of trees that become a refuge for small fauna or home to a large number of organisms including fungi and insects);
- Plant architecture;
- Botanical Rarity; a rare plant certainly acquires a great biological value;
- Value, historical, cultural, religious: they are tall trees that bear a precise reference to events or memories relevant from the historical, cultural, documentary or local traditions point of view; this is also the case of tall trees inserted in particular architectural complexes of historical and cultural importance, such as villas, monasteries, churches, botanical gardens and private historical residences.
- Landscape value: for example rows and trees of particular landscape value, including those inserted in urban centers;
We can also use the following classification:
- Monumental trees not included in the national list (poor protection)
- Monumental trees included in the national list (Protected trees Art. 7 Law 10/2013) (first level protection)
- Monumental trees of Notable public interest (Landscape constraint pursuant to Art. 136 of Legislative Decree 42/2004) (second level protection)
In order to understand the classification given, let's see how the current legislation identifies the sector.
La law 14 January 2013, n. 10, in addition to dictating rules for the development of urban green spaces, it is the law that, together with the relative implementing decree 23 October 2014, defines and protects documentary trees, guaranteeing them specific landscape protection. Launched with the aim of providing uniqueness criteria useful for the protection and safeguarding of monumental trees, the law, in addition to providing a definition of the monumental tree, which each Region is obliged to implement at the legislative level, establishes, among other things, 'of course:
- each Municipality carries out a census of the monumental trees falling within the territory of its own competence, transmitting the results to the Regions;
- the Regions, after an appropriate investigation of the municipal proposals, draw up a regional list to be sent to the State Forestry Corps (see note *) in order to create a national list of monumental trees.
Note (*): From 1 January 2017, with the elimination of the State Forestry Corps, the coordination, collection, management of information and issue of opinions required by law have been transferred to the Ministry of Agricultural, Food and Forestry Policies.
In order to ensure maximum protection for monumental specimens, the law prohibits their demolition as well as changes to the related equipment, reserving the possibility of carrying out interventions of this type only for justified and urgent cases, in the face of municipal authorization and prior mandatory opinion. and binding of the State Forestry Corps. For unauthorized damage and killing, the law, unless the facts constitute a crime, provides for administrative penalties of between 5.000 and 100.000 euros.
Il inter-ministerial decree of 23 October 2014, implementing the regulatory provisions, defined the monumentality criteria on the basis of which to take a census and dealt in detail with the technical and operational aspects of the entire census activity as well as that concerning the preparation of lists at both regional and national level,
The Law 14 January 2013 n. 10 (Article 7, paragraph 1) taken from the Interministerial Decree 23 October 2014 (Article 7, paragraph 1) identifies the "monumental trees".
- tall tree isolated or part of natural or artificial wood formations wherever located or the typical secular tree, which can be considered as rare examples of majesty and longevity, for age or size, or of particular naturalistic value, for botanical rarity and peculiarities of the species, or that bear a precise reference to events or memories relevant from the historical, cultural, documentary or local traditions point of view;
- the rows and trees of particular landscape, monumental, historical and cultural value, including those inserted in urban centers;
- tall trees inserted in particular architectural complexes of historical and cultural importance, such as villas, monasteries, churches, botanical gardens and private historical residences.
Article 7 paragraph 2 of the 2014 inter-ministerial decree also provides further elements for the identification of monumental trees:
