Dataset Direct Download Service (WFS): Sensitivity Cards — Non-sensitive Weighted Mail Cards — Leucorrhinia caudalis (Leucorrhine Large-tailed)

Sensitivity map made by the ODONAT Grand Est network in 2018-2019. The distribution of the species is represented from recent occurrence data (1999-2018 or 2009-2018 by species). These are the 10 x 10 km Lambert 93 meshes in which at least one observation of the species has been made in the recent period. In each of these 10 x 10 km meshes, this presence is represented by the calculation of the proportion of 1 x 1 km meshes in which the species was observed. Any observations shall be taken into account: they can be implanted populations, but also erratic individuals. This layer represents the state of knowledge at the time of its realisation, it should not be considered exhaustive. The presence of the species outside the identified areas is possible.
