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 ( E.Branquart@mrw.wallonie.be
).
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.

1A. Total number of PFA types in the country N = 13
1B. Number of PFA types primarily dedicated to
(conservation and scientific purposes) * forest biodiversity
N = 8
* corresponding to 1.1 to 1.3 categories of the MCPFE classification
** By the Law of Protected Areas, National and Regional Parks are multifunctional territories corresponded to 2 category (MCPFE classification) including areas under conservation regime (categories 1.1 to 1.3, that is strict reserves and nature reserves, SPA, WKH) whereas the present Regulations and rules of the each given park include biodiversity conservation already.
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.

Comments :
The main types of PFA’s are oriented to the biodiversity conservation. Thee A types (codes A-A'') as well as B and C attributed to areas of the conservation priority. D code attributed to areas of complex protected areas (Biosphere Reserve). Areas of E & F codes are SPA (Natura 200) and Woodland Key
Habitats (WKH). The process of their designation and implementation is continued away. Lithuanian
National & Regional parks are complex multifunctional areas, which include conservation of diversity, natural complexes, habitats and species in the Regulations of each given territory. However, it is not task of the paramount importance. Strict Nature Reserves and Kuršių Nerija National Park are exclusively public ownership.
3. Use of scientific selection criteria
3A. Are scientific standardised criteria currently used for the selection of PFA in your country ? ..... Yes
3B. Do they prevail on pragmatic criteria (e.g. site history, owner and availability) ?
........................... No
3C. Since when are scientific criteria used for site designation ? .................................................... 1993
Comments :
Up to above-mentioned 1993, designation of the protected areas mostly grounded on the criteria of landscape values, naturalness and episodic findings of habitats of the rare species. Since 1993, the system of protected areas is correcting by the more objective criteria taking into consideration naturalness, representativity, dynamic status if naturalness is lost, rareness and threateness, biodiversity, investigative level and scientific value as well as functional reliability, spatial distribution, aesthetic and economic values, connectivity with the whole natural protection network, etc. These are included into the Law of Protected Areas and other post-legal acts
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.)?

Are there other primary scientific criteria used for site designation that have been omitted in the Table
2 ? Preceding proposal :
- Dynamic status
- Scientific, aesthetic value
- Rareness
- Landscape attractiveness
- Connectivity with the whole natural protection network
- threatening level - has been included as 1B and 1E
- Naturalness – it is perceived as mentioned potential natural vegetation (1C) but it is not the same as the forest cover continuity because intensively managed and continually overgrown forest is unnatural yet
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.
Criteria 1 = 1B. Threatened habitats. The primary importance has for the strict nature reserves (code
A, SPA (code E, designation and implementation is continued, proposed for approval 300 designated territories by Habitat Directive ( State Protected Area Service, 2003 ), Woodland key habitats
(code F) ( State Forest Management Service, 2003 ) ( see PFA table) as well as for some Nature reserves while it is on an average only incidental importance (2). 1A criterion “Habitat representativity” wasn’t taken into consideration previously within designation of existing protected areas, however, it is mentioned in the present legal acts.
Criteria 2 = 1C. Phytocoenotic integrity. Criterion is important for the designation of Strict Reserves (A) while the rareness of communities is important for Nature Reserves (code B). Determined by the
Law of Protected Areas, and Regulations of the each given protected area. Quantitative characteristics are presented in the Country report and PFA table (WG1)
Criteria 3 = 1D & 1E. Presence of signal species. Presence of red listed species . Presence of the signal species was not used previously per se excluding current SPA and WKH (codes E & F); red listed species and typical communities is the main criterion for the selection of Nature Reserves
(code B) as well as for the Special Protected Areas (code E, Natura 2000, n= 90) ( State Protected
Area Service 2003 ), Woodland Key Habitats (F)( State Forest Management Service 2003) . Determined by the Law of Protected Area and post-legal acts (additionally, see PFA table)
Criteria 4 = 2C. Presence of old-growth stages.
The main criteria for designation of Strict Reserves
(codes A – A''). It is usable for the designation of Woodland Key Habitats (code F). The old trees are important objects of nature heritage. Determined by the Law of Protected Area, regulations of certain object, other legal acts. Minimal dead wood amount is the most important for the designation of Woodland Key Habitats (F) as well as for the certain Special Protected Areas (SPA) (E) taking into consideration the Bird Directive (79/409/EC) and Habitat Directive (92/43/EEC) transferred to the Law of Protected Areas, the List of the Selection Criteria of SPAs and SACs (Species Areas Of
Conservation) confirmed by the executive orders of the Minister of Environment, other post-legal acts related to Natura 2000 network in Lithuania. Presently, 390 designated SPA are proposed for approval ( State Protected Area Service, 2003)
Criteria 5 = Forest cover continuity over time.
It is most important for the designation of the Strict
Reserves (codes A – A''). Presented in the scientific publications, indirectly, it is mentioned in The
Program of Protection of Strict Nature Reserves, resolutions of the Ministry of Environment, regulations of the Strict Reserves. Quantitative characteristics are presented in the Country report and PFA table (WG1)
Criteria 6 = Old-growth continuity over time. Relatively less impact of forest management to forest as well as above-mentioned criterion are the important for the designation of Woodland Key Habitats
(G). Confirmed by the orders of the Minister of Environment, WKH inventory executive specifications
(LithuanianSwedish project “Pilot Wood Key Habitat Inventory in Lithuania” started in 2001, will be fulfilled in 2005; presently WKH occupy 12716 ha with mean area 3.3 ha).
