PRESENCE AND BREEDING
The data shown above refer to the global results, which include:
- Systematic Visits;
- Non-Systematic Visits;
- Incidental Registrations;
FREQUENCY OF OCCURRENCE
The frequency of occurrence is determined exclusively from the systematic visits.
The data are the results of two visits of one hour each, divided into 10-minute periods, which results in a total of 12 periods per square (see Methodology).
The frequency of occurrence is therefore listed in the following manner:
- Species detected in a total of 1 to 4 periods – Low frequence
- Species detected in a total of 5 to 8 periods – Medium frequence
- Species detected in a total of 9 to 12 periods – High frequence
