Dataset Direct Download Service (WFS): Sensitivity Maps — Maps Natural Regions — Conocephalus_dorsalis (Reedy Coocephalus)
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.
ODONAT大东部大区(ODONAT Grand Est)网络于2018—2019年制作的物种敏感性分布图。 该物种的分布情况基于近期观测记录进行表征,不同物种对应1999—2018年或2009—2018年的观测数据。 此类制图覆盖的区域包含两类:一类是近期内至少有一次该物种观测记录的自然区域,另一类则是经专家高度推测存在该物种或存有历史观测数据的自然区域。 对于存在近期非边缘性观测记录的自然区域,该物种的出现情况通过统计观测到该物种的1×1千米网格占比来表征。若需了解具体计算方法,请参阅《自然区域地图说明手册(Natural Regions Map Explanation Sheet)》。 自然区域指非生物环境(地形、地质、气候等)相对均一的区域。 实际上,只要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其他区域也存在适宜其生存的栖息地。 所有观测记录均纳入考量范畴:既包括人工引种的种群,也包括偶见的零散个体。 本图层仅反映其制作完成时的认知现状,不应被视为全面完整的数据集。在本图层划定的区域之外,仍有可能存在该物种的分布点位。 如需获取更多信息,请参阅说明卡片阅读指南及相关PDF格式说明卡片。
