Data on three-year zooplankton monitoring in ditches of the apple orchard region of Altes Land, Germany : In Press, Accepted Manuscript
The data presented in this article are related to the research article 'Chemical and biological monitoring of the load of plant protection products and of zoocoenoses in ditches of the orchard region Altes Land' (Süß et al., 2006) , which is only available in the German language. The zooplankton data presented here were acquired from four ditches (three ditches were located in apple orchards, and one ditch was located in a grassland region) between 2001 and 2003 (Lorenz & Müller, 2018) . This article describes the methods used to determine zooplankton species in the samples. The field data set is publicly available at the OpenAgrar repository under https://doi.org/10.5073/20181213-163305 . It is related to the field data set of Lorenz et al. (2018) ,  where pesticide monitoring data from the same ditches and time period were presented.
