Report on Art. 6(4)
If, in spite of a negative assessment of the implications for the site and in the absence of alternative solutions, a plan or project must nevertheless be carried out for imperative reasons of overriding public interest, including those of social or economic nature, the Member State shall take all compensatory measures necessary to ensure that the overall coherence of Natura 2000 is protected. It shall inform the Commission of the compensatory measures adopted.
Where the site concerned hosts a priority natural habitat type and/or a priority species the only considerations which may be raised are those relating to human health or public safety, to beneficial consequences of primary importance for the environment or, further to an opinion from the Commission, to other imperative reasons of overriding public interest.’

Obligation: Information of the Commission of the compensatory measures adopted
Form: Provided by the Commission
Praxis: 42 cases reported in 2004-2006; Assessment of effects frequently vague and too general; scarce information on concrete impacts; mix up of mitigation and compensation measures; compensatory measures not related to the impacts

the reporting format or guidelines are insufficient or insufficiently precise;
the reports produced by the Member States do not always fully respond to the guidelines, and/or are late or incomplete; and
the information is not sufficiently validated at EU level, and cannot be compared to independent data on trends and status to assess effectiveness.

What is an occurrence?
Species: Locality with appropriate habitat where the species very likely occurs and which is clearly separated from another occurrence
Habitat type: Clearly delineated polygon
Need for assessing the frequency of habitats and species

Sampling approach
Complete sampling: Less than 100 occurrences. Advantage: no statistics needed
Representative Sampling: Necessary if main unit is too big; Recording of a representative sample. Statistical Tests needed.
6.-7.4.2009 | Folie 78
The sample size is dependent on:
Level of Significance: Probability that a measured difference is real
Power: Probability to detect a differential
Effect size: measure of the strength of the relationship between two
variables
Standard deviation
Correlation between the observed dates
