Abstract

The European green toad, (Laurenti, 1768), is a rare and protected species in Vienna. In spring and summer 2020, we conducted a survey to assess size and status of its population in Donaufeld, an agricultural area designated for real estate development. Recaptures of photographically registered toads allowed to estimate the population size with 137 individuals (confidence interval: 104-181). Comparatively large body size indicates the presence of a well-established population. Reproductive success was high in the study year. A mismatch mating of a male . with a female was observed. Mitigation measures are needed to support this population facing imminent habitat deterioration.

摘要

欧洲绿蟾蜍（Laurenti，1768年）是维也纳的一种珍稀保护物种。2020年春夏，我们在多瑙费尔德进行了一项调查，以评估其在这片指定用于房地产开发的农业区域的种群规模和状况。通过对有照片记录的蟾蜍进行重新捕获，估计该种群数量为137只（置信区间：104 - 181）。相对较大的体型表明存在一个成熟的种群。在研究年份繁殖成功率较高。观察到一只雄性……与一只雌性……的错配交配情况。需要采取缓解措施来支持这个面临栖息地即将退化的种群。
