Sensitivity Maps — Maps Natural Regions — Athene noctua (Chevêche d’Athena)
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. Refer to the card reading instructions as well as PDF cards for more information.
本数据集为奥多纳大东部网络(ODONAT Grand Est)于2018至2019年间制作的物种敏感性分布图。物种分布信息基于近期出现记录生成,不同物种分别采用1999-2018年或2009-2018年的观测数据。 该数据集涵盖两类自然区域:一类为近期至少开展过一次该物种观测记录的区域,另一类为经专家高度疑似存在该物种或拥有较老观测数据的自然区域。 针对存在近期非边缘观测记录的自然区域,通过计算观测到该物种的1×1km网格占比来表征其分布状况。计算方法的详细说明请参阅《自然区域地图说明手册》(Natural Regions Map Explanation Sheet)。 自然区域指非生物条件(地形、地质、气候等)相对均一的区域。 事实上,只要在某一自然区域内观测到该物种(即便仅单个点位),即可强烈推定该自然区域内其他位置亦存在适宜该物种的生境。 所有观测记录均予以纳入,既包括定植种群,也包括偶见个体。 本图层仅反映制作完成时的认知现状,不应被视为穷尽所有分布的详尽资料。在已识别区域之外,仍有可能存在该物种的分布记录。 更多信息请参阅卡片阅读说明及配套PDF格式说明卡片。
