We present an online database that provides unrestricted and free access to over 16 million plant phenological observations from over 8,000 stations in Central Europe between the years 1880 and 2009. Unique features are (1) a flexible and unrestricted access to a full-fledged database, allowing for a wide range of individual queries and data retrieval, (2) historical data for Germany before 1951 ranging back to 1880, and (3) more than 480 curated long-term time series covering more than 100 years for individual phenological phases and plants combined over Natural Regions in Germany. Time series for single stations or Natural Regions can be accessed through a user-friendly graphical geo-referenced interface. The joint databases made available with the plant phenological database PPODB render accessible an important data source for further analyses of long-term changes in phenology. The database can be accessed via www.ppodb.de. Full text available at: http://link.springer.com/article/10.1007/s00484-013-0650-2
... In addition, it has collated and stored earlier historical phenological data from unofficial networks, including that of Prof. Ihne of Darmstadt who coordinated a German scheme from 1883 to 1941 (Menzel et al., 2005). Observational records for the period 1936 to post-World War II are available from several other publications as well as from DWD yearbooks, and these data are hosted on the PPODB (plant phenological online database) (Dierenbach et al., 2013). We obtained all German first flowering dates (FFDs) of Coltsfoot from the DWD/PPODB, together with information on each station's latitude, longitude and elevation. ...
