TERENO (Terrestrial Environmental Observatories) bird monitoring in six agriculturally dominated landscapes of Saxony-Anhalt (Germany)

Survey points were located far enough apart (> 500 m) to sample spatially distinct bird communities within each site. A bird survey within one year was performed with three visits in the following periods: (1) 1-30 April, (2) 1-20 May, (3) 21 May-20 June. Based on the birds recorded in the field, the observed bird numbers at each point were translated into territory numbers per species as an expert guess.

With the start of the TERENO project (www.tereno.net) in 2009 contributing to the LTER network (Long-Term Ecosystem Research) in Germany (www.lter-d.de) and internationally as well (www.lter-europe.net) and the following surveys in 2012, 2013, 2014 the sites Harsleben (HAR) and Siptenfelde (SIP) were added. Although the monitoring program was designed to sample every three years, the years 2013-14 were taken as an additional check for variation of counts between years.

Metadata about the sites and related activities and data sets can be found in the DEIMS Repository for Research Sites and Datasets (data.lter-europe.net/deims).
