Map visualisation service (WMS) of the dataset: Sensitivity Maps - Natural Regions Maps - Vipera_aspis (Viper aspic)
Description
Sensitivity maps made by the ODONAT Grand Est network in 2018 - 2019.
The distribution of the species is represented on the basis of recent occurrence data (1999 – 2018 or 2009 – 2018 depending on the species).
These are natural regions where at least one observation of the species has been made in the recent period as well as natural regions where the species is strongly suspected (expert reports) or benefits from older data.
In each of the natural regions with recent non-marginal observations, this presence is represented by calculating the proportion of 1 x 1 km meshes in which the species was observed. For an explanation of the calculation method, 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 at a single location) makes it possible to strongly presume the existence of other favourable habitats elsewhere in the natural region.
Any comments 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 realization, it should not be considered exhaustive. The presence of the species outside the identified areas is possible.
