Resting bird data
Between 1990 and 2013, all resting bird data of Lower Saxony have been managed in a purpose-built database on behalf of the State Bird Observatory & Field Centre. Analysis tools have been developed allowing the administrator to extract data.
Distribution maps, phenologies or trends can be calculated for parts of or the entire region assessing ecological features. The respective evaluation methods have been developed in cooperation with the State Bird Observatory & Field Centre (Krüger et al. 2013 (1)).
In cooperation with the Common Wadden Sea Secretariat these resting bird data are evaluated within the framework of the Trilateral Monitoring and Assessment Programme for the Wadden Sea. Data on the distribution and phenology of resting birds as well as trends and their causes are published in reports covering different aspects (e.g. Blew et al. 2005 2007, 2013, 2015, 2016; Ens et al. 2009, Laursen et al. 2010). A summarised presentation can be found in the Wadden Sea Quality Status Reports (QSR) (Blew et al. 2018) which are published at regular intervals.
Data management tasks and trend analyses were also carried out on behalf of the global organisation “Wetlands International” within the framework of the International Waterbird Census .
