Citizen science platforms for sharing photographed digital vouchers, such as iNaturalist, are a promising source of phenology data, but methods and best practices for use have not been developed. Here we introduce methods using Yucca flowering phenology as a case study, because drivers of Yucca phenology are not well understood despite the need to synchronize flowering with obligate pollinators. There is also evidence of recent anomalous winter flowering events, but with unknown spatiotemporal extents.

使用公民科学家的照片进行大规模植物物候评估的方法。

用于共享照片数字凭证的公民科学平台，例如 iNaturalist，是物候数据的有前途的来源，但尚未开发出使用方法和最佳实践。在这里，我们介绍使用丝兰开花物候学作为案例研究的方法，因为尽管需要与专性授粉媒介同步开花，但丝兰物候学的驱动因素尚不清楚。也有证据表明最近异常的冬季开花事件，但时空范围未知。
