Description
Summary:Julius-Kühn-Archiv, 442 : The national biodiversity indicator, ‘Species diversity and landscape quality’, in short, ‘bird indicator’, shows the index level and the trend of bird populations. However, it does not allow clarification of cause-effect relationships between changes in inventory of bird species and agricultural land use to derive recommendations for biodiversity protection. For this reason, an agriculturally-based bird monitoring scheme was developed, which can be integrated well into the existing bird monitoring. The method was designed hierarchically. Bird surveys were carried out on 1 km² plots by field surveys in eight time steps from March to July, synchronous with agricultural surveys on larger plots of 1.43 km². The obtained data allow analysis at the spatial scales of agricultural landscapes, field crops and habitats, vegetation structures, and the habitat matrix (HM) of breeding birds. Newly developed methods for calculating the dynamic abundance, vegetation structures on land and the HM were applied as an example to the indicator species Eurasian Skylark (Alauda arvensis), Yellowhammer (Emberiza citrinella), Corn Bunting (Emberiza calandra), Yellow Wagtail (Motazilla fl ava), Whinchat (Saxicola rubetra) Red-backed Shrike (Lanius collurio). Using these methods, favorable vegetation structures on farmland areas, field crops and habitats for biodiversity conservation were determined.
