    Data Set Information:


    道路A项目涉及Pirzowice规划A1高速公路路段的一部分;该路段位于西里西亚Voivodship的北部边界,长约75 km。现场研究涉及拟建项目区域两侧宽度为500 m的狭长地带。现场盘点于2010年[1]和2011年[2,3]进行。2014年至2016年间进行的Marek So??tysiak观察补充了这些清单的结果[4]。最后,第一个项目包括80个两栖动物繁殖地。

    在S52高速公路Bielsko Biaa-Wadowice-Gogocz3w段上规划的Beskidy整合道路的两个变体附近编制了道路B清单。该路段的长度约为60 km。在2010年进行的清查中,[5]描述了125个真实和潜在的两栖动物发生地点。爬虫名录的方法包括地图分析、文献和档案数据分析,然后是实地观察。与第一种情况一样,清查是在春季进行的,包括观察水库中两栖动物的出现情况。研究区域包括一条500米宽的交通带,用于规划道路的每一种变体。为了进行最终实验,考虑了109个两栖动物发生地点。

    Name and symbol type description:
    1) ID a€“ vector ID (not used in the calculations)
    2) MV a€“ motorway (not used in the calculations)
    3) SR -> Surface of water reservoir numeric [m2]
    4) NR -> Number of water reservoirs in habitat - Comment: The larger the number of reservoirs, the more likely it is that some of them will be suitable for amphibian breeding.
    5) TR -> Type of water reservoirs:
    a. reservoirs with natural features that are natural or anthropogenic water reservoirs (e.g., subsidence post-exploited water reservoirs), not subjected to naturalization
    b. recently formed reservoirs, not subjected to naturalization
    c. settling ponds
    d. water reservoirs located near houses
    e. technological water reservoirs
    f. water reservoirs in allotment gardens
    g. trenches
    h. wet meadows, flood plains, marshes
    i. river valleys
    j. streams and very small watercourses
    6) VR - Presence of vegetation within the reservoirs:
    a. no vegetation
    b. narrow patches at the edges
    c. areas heavily overgrown
    d. lush vegetation within the reservoir with some part devoid of vegetation
    e. reservoirs completely overgrown with a disappearing water table
    Comment: The vegetation in the reservoir favors amphibians, facilitates breeding, and allows the larvae to feed and give shelter. However, excess vegetation can lead to the overgrowth of the pond and water shortages.
    7) SUR1 - Surroundings 1a€”the dominant types of land cover surrounding the water reservoir
    8) SUR2 - Surroundings 2a€”the second most dominant types of land cover surrounding the water reservoir
    9) SUR3 - Surroundings 3a€”the third most dominant types of land cover surrounding the water reservoir
    Comment: The a€?surroundingsa€? feature was designated in three stages. First, the dominant surroundings were selected. Then, two secondary types were chosen.
    a. forest areas (with meadows) and densely wooded areas
    b. areas of wasteland and meadows
    c. allotment gardens
    d. parks and green areas
    e. dense building development, industrial areas
    f. dispersed habitation, orchards, gardens
    g. river valleys
    h. roads, streets
    i. agricultural land
    The most valuable surroundings of water reservoirs for amphibians are areas with the least anthropopressure and proper moisture.
    10) UR - Use of water reservoirs:
    a. unused by man (very attractive for amphibians)
    b. recreational and scenic (care work is performed)
    c. used economically (often fish farming)
    d. technological
    11) FR - The presence of fishing:
    a. lack of or occasional fishing
    b. intense fishing
    c. breeding reservoirs
    Comment: The presence of a large amount of fishing, in particular predatory and intense fishing, is not conducive to the presence of amphibians.
    12) OR - Percentage access from the edges of the reservoir to undeveloped areas (the proposed percentage ranges are a numerical reflection of the phrases: lack of access, low access, medium access, large access to free space):
    a. 0a€“25%a€”lack of access or poor access
    b. 25a€“50%a€”low access
    c. 50a€“75%a€”medium access,
    d. 75a€“100%a€”large access to terrestrial habitats of the shoreline is in contact with the terrestrial habitat of amphibians.
    13) RR Minimum distance from the water reservoir to roads:
    a. <50 m
    b. 50a€“100 m
    c. 100a€“200 m
    d. 200a€“500 m
    e. 500a€“1000 m
    f. >1000 m
    Comment: The greater the distance between the reservoir and the road, the more safety for amphibians.
    14) BR - Building development - Minimum distance to buildings:
    a. <50 m
    b. 50a€“100 m
    c. 100a€“200 m
    d. 200a€“500 m
    e. 500a€“1000 m
