Dataset Direct Download Service (WFS): Sensitivity Maps — Maps Natural Regions — Myotis_daubentonii (Daubenton Murin)
收藏资源简介:
Sensitivity maps 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 natural areas in which at least one observation of the species has been carried out in the recent period, as well as natural regions where the species is highly suspected (i.e. experts) or has older data. In each of the natural regions with recent non-marginal observations, this presence is represented by the calculation of the proportion of 1 x 1 km meshes in which the species was observed. For an explanation of the method of calculation, refer to the Natural Regions Map Explanation Sheet. Natural regions identify areas 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) provides a strong presumption of other favourable habitats elsewhere in the natural region. 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.

由ODONAT Grand Est观测网络于2018—2019年制作的敏感性地图。 该物种的分布范围基于近期出现记录进行表征,不同物种对应1999—2018年或2009—2018年的观测数据。 此类区域涵盖近期至少开展过一次该物种观测的自然区域,以及经专家高度推定存在该物种或存有历史观测记录的自然区域。 对于每个存有近期非零星观测记录的自然区域,该物种的存在情况通过统计观测到该物种的1×1平方千米网格占比进行表征。如需了解计算方法的详细说明,请参阅《自然区域地图说明手册》。 自然区域指非生物条件(地形、地质、气候等)相对均一的区域。 实际上,在某一自然区域内观测到该物种(即便仅在单个点位),即可高度推定该自然区域内的其他区域也存在适宜其生存的栖息地。 所有观测记录均需纳入考量:既包括人工引种的种群,也包括偶然出现的个体。 本图层仅反映其制作完成时的认知现状,不应被视为全面详尽的数据集。该物种在已识别区域之外存在分布的可能性依然存在。 如需获取更多信息,请参阅卡片读取说明文档及配套PDF卡片。
