This article presents the floristic, structural, and syntaxonomical features of plant assemblages in temporary wetlands and the pattern of the corresponding habitat types; according to the Habitats Directive. Nine pristine temporary wetlands covering a wide range of shapes, elevations and substrates were monitored. The "within temporary wetlands" hydrological gradient was strong enough to drive the vegetation and habitat type patterns. Plant assemblages presented a spatial arrangement in three concentric belts repeatedly present in each site in the same relative position. The presence of the H3120 habitat type was recognized in the central and in the intermediate belt. The outer belt was the more suitable for the presence of the H3170* priority habitat. Therefore, it should represent the main conservation target within temporary wetlands. On the other hand, it was the smallest in size (only 13% of the total surface) and in some cases absent, inconspicuous, or severely fragmented.
本文介绍了临时湿地植物群落的植物区系、结构和句法特征，以及根据《栖息地指令》相应的生境类型模式。监测了九个原始的临时湿地，这些湿地涵盖了广泛的形状、海拔和基质。“临时湿地内”的水文梯度足以驱动植被和生境类型的模式。植物群落呈现出一种空间排列，在每个站点的三个同心带中以相同的相对位置重复出现。在中心和中间带都存在 H3120 生境类型。外部带更适合 H3170*优先生境的存在。因此，它应该是临时湿地内的主要保护目标。另一方面，它的面积最小（仅占总面积的 13%），在某些情况下缺失、不明显或严重破碎。
