The conservation actions of endangered plant species require a clear knowledge of their habitats. Guss. (Urticaceae) is a rare endemic plant species occurring on shady cliffs in the southern-eastern part of Sicily. In the last century, the extreme anthropogenic alterations of Hyblaean plateau have caused the continuous and unrestrained fragmentation of natural habitats and consequently the reduction and disappearance of some plant species. A total of 52 vegetation plots, of which 34 are unpublished, were analyzed in order to characterize the floristic composition of the community. All the relevés were classified using classification and ordination methods. The species is mainly linked to shady and wet rock habitats, and only secondarily colonizes the undergrowth shrubs. According to IUCN criteria, we propose a new risk status for this species and the establishment of a new habitat (92/43CEE) for correct long-term conservation. Finally, a new association, , which falls within the alliance ( class), was described. This study can provide useful information for the management and conservation of .
濒危植物物种的保护行动需要对其栖息地有清晰的了解。古斯荨麻（荨麻科）是一种稀有的特有植物物种，生长在西西里岛东南部阴凉的悬崖上。在上个世纪，伊布利亚高原极端的人为改变导致了自然栖息地的持续且无节制的破碎化，进而造成一些植物物种数量减少和消失。为了描述该群落的植物区系组成，共分析了52个植被样地，其中34个是未发表的。所有的样方都使用分类和排序方法进行了分类。该物种主要与阴凉潮湿的岩石栖息地相关，其次才在林下灌木中生长。根据世界自然保护联盟（IUCN）的标准，我们为该物种提出了新的风险状况，并为其长期正确保护建立了新的栖息地（92/43CEE）。最后，描述了一个新的群丛，它属于联盟（纲）。这项研究可为古斯荨麻的管理和保护提供有用信息。
