In accordance with the 92/43/EEC "Habitats" Directive, Mediterranean temporary ponds are identified as a priority natural habitat within the European context. They are a very interesting and unique habitat type, as ecological conditions can vary greatly in a short period of time. Due to their small size, many Mediterranean hydrophytic bryophytes typical of this habitat are often overlooked or misinterpreted. Their distribution, habitats, ecology, and strategies are generally poorly understood. Several of them are currently considered rare or endangered in the Mediterranean. As these ponds are particularly sensitive to human activities and natural changes, such bryophytes and associated vegetation communities may be at risk. This study is focused on their floristic variability in different environmental conditions in two sites of particular phytogeographic interest in the Mediterranean area. In the Sardinian of Giara, 56 taxa (50 Bryophyta and 6 Marchantiophyta) were found, and in the Umbria Piana di Ferretto, 54 taxa (34 Bryophyta and 20 Marchantiophyta) were documented. The taxa from the two areas were analysed and compared. Life strategies, life macroforms, light and moisture preferences, chorological elements, and moisture belts were considered. The data are presented here together with information on the phytogeography and ecology of the species recorded. The findings indicate that a bespoke monitoring strategy and dedicated conservation measures are essential for the effective protection of bryophytes, ensuring the achievement of meaningful and sustainable conservation outcomes.
根据92/43/EEC“栖息地”指令，地中海临时池塘在欧洲范围内被确定为优先自然栖息地。它们是一种非常有趣且独特的栖息地类型，因为生态条件在短时间内可能会有很大变化。由于其面积较小，许多典型的地中海水生苔藓植物常常被忽视或误解。它们的分布、栖息地、生态和生存策略通常了解甚少。其中一些目前在地中海地区被视为珍稀或濒危物种。由于这些池塘对人类活动和自然变化特别敏感，此类苔藓植物及相关植被群落可能面临风险。本研究聚焦于地中海地区两个具有特殊植物地理学意义的地点，在不同环境条件下它们的植物区系变异性。在撒丁岛的贾拉，发现了56个分类群（50个苔藓植物门和6个地钱植物门），在翁布里亚的费雷托平原，记录了54个分类群（34个苔藓植物门和20个地钱植物门）。对这两个地区的分类群进行了分析和比较。考虑了生存策略、生活大型形态、光照和湿度偏好、分布区系成分以及湿度带。此处呈现的数据以及所记录物种的植物地理学和生态学信息。研究结果表明，定制的监测策略和专门的保护措施对于有效保护苔藓植物至关重要，可确保实现有意义且可持续的保护成果。
