lisa.reiss@umweltbundesamt.at 0009-0004-9535-5839 Selection of permanent monitoring points Repeated recording of occurrences Subsequent data storage, management, and harmonisation The eLTER site Zöbelboden is a remote forest site located within the Kalkalpen National Park in Upper Austria. The Zöbelboden was established in 1992 as the only Integrated Monitoring site in Austria under the UN Convention on long-range transboundary air pollution (CLRTAP). In 2006 it became part of LTER Austria. In 1997, 55 permanent monitoring points for standardized point counts were established. One additional monitoring point was added in 2005, followed by the establishment of 14 further points in 2025. At each monitoring point, all bird contacts were recorded from a fixed location at the center of a circular plot with a radius of 50 meters during a five-minute observation period. A contact is defined as the observation of a singing male, a calling individual, a family group, or a nest, as well as indirect evidence of presence such as droppings, food remains, traces of foraging, or other behavioral indications. This information is stored in the extended measurements or facts-file. The observation of a singing male is generally interpreted as evidence of a breeding pair. Each monitoring point was surveyed three times per breeding season. In 2005, incidental observations recorded outside the framework of the standardized point counts were additionally collected and are included in the dataset; these records are indicated as incidental observations in dwc:samplingProtocol. In 2025, the standardized point counts were expanded to include distance sampling, whereby all contacts detected beyond the 50-metre radius were also recorded; these records are indicated as distance sampling in dwc:samplingProtocol. Data collected in 1997 were preserved in an aggregated form: all three visits to a single monitoring point were combined into one event with aggregated bird occurrence data. Bird behaviour was documented as "behaviour1" and "behaviour2", as reflected in the extended measurements or facts in this dataset. It is not documented how these two behaviour fields were originally distinguished.
