Questionnaire: selection criteria
of protected forest areas (PFA) in Europe
This questionnaire aims at gathering detailed information about selection criteria of PFA in Europe in
order to fulfil a priority task of the WG1 of the Profor COST action. Please fill in this questionnaire and
send it to Etienne Branquart ([email protected]).
Conservation and natural value of forest ecosystems
The creation of protected forest areas may fulfil two main motivations related to biodiversity: to
maximise either conservation value or natural value (i.e. naturalness). The first one aims to protect key
sites for the conservation of rare or threatened species and habitats. The second one aims to restore
natural structures and processes typical of pristine woodlands. Naturalness quest meet therefore also
scientific objectives (learning by watching nature, close to nature forestry, etc.).
A lot of rare and threatened species are to be found in woodlands characterised by a high naturalness
such as old growth forests. For instance, saproxylic species are typically linked to over-mature trees or
to large woody debris, two key structural elements often eliminated from managed forests. It means
that naturalness objectives usually fulfil conservation ones. However, the opposite is not always true.
Conservation management does not always lead to the restoration of natural landscapes: dry
grasslands, heathlands and coppice woodlands are typically distinguished by a high conservation
value (they shelter numerous red-listed species) but a low naturalness.

1. Number of PFA types
1A. Total number of PFA types in the country
1B. Number of PFA types primarily dedicated to forest biodiversity
(conservation and scientific purposes)*
N=5
N=2
* corresponding to 1.1 to 1.3 categories of the MCPFE classification
2. Motivations
The main motivations to designate PFA matching 1B criteria could be: (1) mainly a conservation target
(should be based on species or habitat action plans and can involve active management for
conservation purposes), (2) mainly a naturalness target (restoration of dynamic natural processes), (3)
both of them, depending on individual areas within a single PFA type.
Please fill in the following table for the PFA types primarily dedicated to the conservation of forest
biodiversity (cf 1B). In the last column (prime motivation), indicate (1)-(3), according to the description
here above.

3. Use of scientific selection criteria
3A. Are scientific standardised criteria currently used for the selection of PFA in your country ? ..... Yes
Scientific criteria are used, however they are not strict standarized, see country report.
3B. Do they prevail on pragmatic criteria (e.g. site history, owner and availability) ? ......................... Yes
3C. Since when are scientific criteria used for site designation ? .................................................... 1970
4. Types of selections criteria
For each of the PFA types considered in Table 1, fill in the following table. Please use the following
grading: (1) primary importance, (2) incidental importance and (3) not taken into consideration.
Criteria definition
1A/ Habitat representativity: does PFA selection process aims to contain a representative selection of all forest types
present in the country?
1B/ Threatened habitats: does PFA selection process focus on rare and threatened habitats (e.g. prioritary Natura 2000
habitats)?
1C/ Phytocoenotic integrity: does PFA selection process focus on forest sites with a representative and undisturbed
vegetation (potential natural vegetation)?
1D/ Presence of signal species: are indicator species of natural conditions (forest continuity and integrity) used for PFA
selection in your country?
1E/ Presence of red listed species: does PFA selection process focus on specific rare and threatened species (e.g.
Natura 2000 species)?
2A/ Vertical and age structure: is a complex vertical and age structure a prerequisite for PFA selection? Do all the forest
developmental phases have to be represented into individual reserves?
2B/ Natural regeneration: is the presence of large amounts of young trees and saplings another prerequisite?
2C/ Old growth stages: does the selection process focus on old-growth areas characterised by the presence of overmature trees and minimal amount of dead wood?
2D/ Soil and hyrdology integrity: does PFA selection process focus on sites with undisturbed soils and hydrology,
including water quality and drainage?
3A/ Forest cover continuity over time: does PFA selection process focus on ancient forests with a long cover continuity
over time?
3B/ Old-growth continuity over time: ditto, with a continuity in over-mature trees and dead wood within the forest.
3C/ Minimal area for PFA designation: is a minimal structural area a prerequisite for PFA selection?
3D/ PFA environment and buffer area: is PFA environment taken into account before site selection ? Has it to be
included in a larger forest areas to fulfil connectivity requirements ? Has it to be remote from roads and pollution
sources ? Etc.
3E/ Habitat diversity within PFA: does PFA selection process focus on habitat complexes made of various habitat types?
3F/ Landform and topography: are PFA concentrated in particular landforms (mountains, flood plains, etc.)?

3F. Landform and topography
Are there other primary scientific criteria used for site designation that have been omitted in the Table
2?
NB! The criteria for National Parks not normally are connected to forest or forested area
In the last 10 years large size itself has been a criteria. (696 out of 819 present PFAs have a size less
than 1km²).
5. Quantitative assessment
For those criteria of primary importance for PFA selection ((1) in Table 2), explain hereafter how they
are assessed and which benchmarks, references and international or national standards are used. For
example, if minimal structural area is considered as a priority for the designation of some PFA type,
give some indicative value of the minimum size.
All data on the areas managed under and protected according to the Nature protection act is now
presented on web (in Norwegian):

uindex=3&pagename=Naturvernomr%c3%a5der
Criterion 1 = habitat representativity. Representativity is used as one major principle for both
special areas and type areas in the different National Forest Conservation Programs performed since
1980. There is quite close links between habitat types and the used classification of forest types.
Criterion 2 = presence of signal species. The term is not used directly in the selection of areas,
however, i.a. red-listed vascular plants in the nature reserves and the big predators mammals in
National parks have always been given significant value.
Criterion 3 = old growth stages, have been a more important specific criteria in the selection of
Reserves in conifer forests than in broadleaved forests.
Criterion 4 = natural regeneration. In Reserves i conifer forests natural regeneration has been a
prerequisite for selection in the first national conservation plan in the 1980 th. Later the size has been
regarded more important and parts of planted trees and even alien tree species occur in forest
reserves
Criterion 5 = minimal area for PFA designation. No minimal areal is decided, and some few of
especially the broadleaved forest reserves at the northern boarder of distribution can be smaller than
one ha of forest.
