Map visualisation service (WMS) of the dataset: Sensitivity maps — Maps Natural regions — Pipistrellus_nathusii (Nathusius Pipistrell)

Sensitivity maps made by the ODONAT Grand Est network in 2018-2019. The distribution of the species is based on recent occurrence data (1999-2018 or 2009-2018 by species). These are the natural regions in which at least one observation of the species has been made in the recent period as well as natural regions where the species is highly suspected (i.e. experts) or benefits from older data. In each of the natural regions with recent non-marginal observations, this presence is represented by the calculation of the proportion of meshes 1 x 1 km in which the species was observed. For an explanation of the method of calculation, refer to the explanation sheet of the Natural Regions maps. Natural regions identify territories in which abiotic conditions (relief, geology, climate...) are relatively homogeneous. In fact, the observation of a species in a natural region (even in one location) makes it possible to strongly assume the existence of other favourable habitats elsewhere in the natural region. Any comments shall be taken into account: these may 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.
