Birds
Factsheet: Birds are very well suited for monitoring. They are relatively easy to observe and at the same time react quickly to changes in the landscape, so they are good indicator species. In South Tyrol, there are 153 breeding bird species, among them 28 are inserted in Annex I of the Bird Directive (20009/147/EC).
Methods: We followed the protocol of the Italian bird-monitoring project MITO2000, using vocal point counts. The listening time at each point is standardized at 10 minutes. Surveys take place at the beginning of the breeding season until mid-July to exclude most migratory birds. The sampling takes place at dawn and ends in the early morning hours. Data for bird species is collected within a radius of 100 m around the central point of the single sites. At least two repetitions per point are carried out.
