PINK - Dragonfly (Odonata) monitoring for the permanent surveillance of coastal areas in Flanders, Belgium is a sampling event dataset published by the Research Institute for Nature and Forest (INBO). The dataset contains over 2.500 dragonfly (Odonata) observations sampled between 2008 and 2014 at the Belgian coast. The dataset includes 34 species. The data are collected for the project PINK (Permanente Inventarisatie van de Natuurreservaten aan de Kust), which was commissioned by the Agency for Nature and Forest in 2007. The project started with the aim of mapping the natural values on the coast in a more systematic way. A first 3-year phase (PINK I) ran from 2008 to 2010, in which the methodology was set up and an initial assessment was conducted. A second phase (PINK II) ran from 2012 to 2014, which was a continuation of the main components of PINK I, with special attention for invasive species and grasshoppers. A third phase (PINK III) is running from 2014 to 2018. This dataset contains Odonata occurrences observed during PINK I and PINK II.
