ANNEX I
COMMON METHODS FOR THE ESTABLISHMENT OF A PERIODIC INVENTORY OF DAMAGE CAUSED TO FORESTS (Article 2 (1)) I.
General remarks
The purpose of the scheme mentioned in Article 2 (1) is to establish a periodic inventory of the health status of forests in the Member States of the EEC by collecting representative data on the extent and intensity of forest damage and to monitor its development.
This inventory is to be carried out at Community level on the basis of a 16 kilometres × 16 kilometres grid network covering the entire area of each Member State. In addition, Member States may collect information from denser networks in order to obtain for the presentation of their annual report representative data at a national or regional level. For both observation levels (Community and national or regional) the common methods (described below) regarding the choice of the tree sample and the observation criteria shall be adopted.
The inventory is to be undertaken annually between the end of the formation of new needles and leaves and before autumnal leaf discolouration.
II.
Inventory methodology
II.1.
Selection of sample points
Forests, within the meaning of this inventory, are forest tree stands with at least 20 % canopy closure at rotation age (closed forests according to the Food and Agricultural Organization of the United Nations (FAO) definition). However, for stands of Quercus suber and Quercus ilex, canopy closure should be of at least 10 %. The minimum size of the forests to be sampled should be 0,5 hectare.
At Community level, data should be collected by a field inventory using systematically distributed sample points with a grid density of 16 kilometres × 16 kilometres and covering the entire area of each Member State. The 16 kilometres × 16 kilometres grid network is established following the latitude, longitude coordinate system in north-south and east-west directions from the reference point: latitude 50g15m15mm, longitude 09g47m06mm. The coordinates of these points will be transmitted to each Member State by the Commission.
Grid intersection points falling outside a forested area (according to the above definition) should be rejected as sample points although if in the future a new stand is established they must be reconsidered.
Member States which have already established a systematic network may retain the corresponding observation points of these networks for the purpose of establishing the Community network (points coinciding with or those closest to the 16 kilometres × 16 kilometres intersection points) provided that the common methods described below are applied. Member States which do not have or have only partially established such a systematic network shall establish or extend new networks in order to complete the Community network. In this case, a sample point falling in a forest (according to the above definition) should be located precisely at its predetermined geographical location. However, if at such a coordinate point it is impossible to establish a sample, the actual sample point may be shifted within the stand following an objective (unbiased) procedure.
II.2.
Selection of sample trees
At each sampling point, sample trees should be selected according to a stringently defined, objective and unbiased statistical procedure (e.g., four point cross cluster orientated along the main compass directions with corner points at 25 m distance from the grid point using a six-tree sampling process on each subplot or sample trees chosen following a spiral from the plot centre). In younger dense stands where individual crowns are not assessable, the selection of sample trees should be based on a defined geometrical process. This process should be repeated until a sufficient number of trees with assessable crowns has been found. The following selection criteria are to be taken into account:
- Member States may decide on the number of trees to be assessed at each point; however, the sample may not consist of less than 20 trees nor more than 30 and the number must remain constant,
- all tree species are to be included in the assessment. Sample trees should have a minimum height of 60 cm. Only predominant, dominant and co-dominant trees (Kraft: stem classes 1-3) qualify as sample trees for the purpose of damage assessment. Trees of these social groups with broken tops do not qualify as sample trees,
- trees removed as part of management operations may be replaced by new sample trees selected according to an unbiased procedure. If clear-cut, the sample point ceases to exist until a new stand has been established,
- the centre of a sampling unit should be marked for reassessment for the purpose of subsequent inventories. If possible, sample trees should also be permanently marked.
II.3.
Assessment of sample trees
Visual assessment of defoliation and discolouration
It is recommended that defoliation should be estimated in 5 % steps in relation to a tree with full foliage. The final allocation to defoliation classes as defined below should be made after the observations.
Alternatively, defoliation may be evaluated and classified directly into final defoliation classes which are defined as follows:
Class
Degree of defoliation
Percentage of needle/
leaf loss
0
1
2
3
4
not defoliated
slightly defoliated
moderately defoliated
severely defoliated
dead
0 - 10
11 - 25
26 - 60
> 60
Discolouration of the remaining foliage is assessed according to the following 4 classes:
Class
Discolouration
Indicative percentage of
needles/leaves discoloured
0
1
2
3
None or negligible
Slight
Moderate
Severe
0 - 10
11 - 25
26 - 60
> 60
If, in addition, defoliation and discolouration classes are combined, the following combined damage classes must be used:
Defoliation class
Discolouration class
1
2
3
Resulting damage class
0
1
2
3
I
II
III
III

III
0 = not damaged, I = slightly damaged, II = moderately damaged, III = severely damaged,
IV = dead.

II.4.
Data collection
In addition to the above forest damage assessments, the parameters listed below are the mandatory minimum for data collection:
- descriptive code:
- country
- actual latitude, longitude coordinates
- observation point number
- site data:
- altitude
- aspect
- availability of water to principal species
- humus type
- stand data:
- mean age of dominant story
- sample tree data:
- date of observation
- tree number (visible marks) or azimuth and distance (invisible marks)
- tree species
- defoliation
- discolouration
- damage due to easily identifiable causes (insect, fungi, abiotic agents . . .)
- sample trees replaced since the previous observations.
The common census form 1 of this Annex should be used for the 16 kilometres × 16 kilometres Community network, for the collection of the mandatory data and for the transmission of this data to the Commission.
II.5.
Training of field crews
Field crews should consist of two professionals, at least one should be a diploma-level/graduate forester as responsible crew leader. Prior to the beginning of the annual field season, all inventory crews must undergo a period of intensive theoretical and practical training in measurement and assessment procedures and filling out the various forms.
II.6.
Check survey
As customary in national forest inventories, a fraction e.g. 5 to 10 % of field sample points must be remeasured by an independent check-survey crew.
This control survey concerns all measurements and assessments made by the field crews. In case of significant discrepancies, the necessary adjustments of instruments or clarification of instructions and their application must be immediately arranged to avoid serious systematic errors.

Forest damage results
Results shall only be presented in terms of the percentage of trees falling into the different defoliation, discolouration and, where evaluated, combined damage classes (optional). The percentage of needle/leaf loss refers to damage as a result of unknown and known causes. In all tables, the number of trees observed and where possible, the corresponding forested area, should be included.
Total national results must be presented in the above terms by age (< 60 years,8 60 years) and the principal coniferous and broadleaved species following the same tabular presentation on Form T1+2+3. These results should be further broken down to produce a presentation with the same age distinction for each species (Forms TA1+2, TA3, TB1+2, TB3). A table indicating easily identifiable causes of damage should be presented separately.
Where possible, a comparison of the present situation with the previous years is to be made in order to study damage trends.
In addition to the results compiled at national level, Member States should submit results by administrative units (Region, Land, Province, . . .) and where possible ecological unit (growth area, Wuchsgebiet) insofar as these are available. Results are to be presented using Forms A1+2, A3, B1+2 and B3. These tables shall be accompanied by a map indicating the geographical location and extent of the units referred to.
If different grid densities are used within one Member State, the results must be calculated separately for each geographical unit for which a particular grid density has been used.
All results should be commented on and tables clearly explained.
III.
Information regarding possible causes of observed damage
A section of the national report should be devoted to the analysis of important information on the possible causes of the observed damage in particular with reference to atmospheric pollution. Results of any correlations made between different types and stages of forest damage (defoliation, discolouration, other signs of damage) and parameters such as site or stand characteristics, climatic data etc. should be included in the annual report.
IV.
Measures to restore damaged forests
Principal results of any measures or field experiments aimed at maintaining and restoring damaged forests should be presented in the report.
V.
Socio-economical impact of forest damage
Member States should provide any relevant information available on the socio-economical influence of forest damage.
