Cystoseira amentacea is a Mediterranean endemic alga thriving on very shallow rocky substrates. It has been considered as a threatened species, having experienced a steady decline and is therefore protected by international conventions. The historical distribution of the species has been assessed along the French Mediterranean coast, on the basis of 467 articles and herbarium vouchers. We have produced an accurate map of its current distribution and abundance along 1832 km of coastline, through in situ surveys. C. amentacea was observed along 1125 km of shoreline, including 33% of almost continuous or continuous belt. In most of its range, there is no evidence of loss, except in 4 areas of Provence, French Riviera and Corsica. A significant relation was found between the absence or low abundance of C. amentacea and the vicinity of ports and large sewage outfalls. The status of conservation of the species should therefore be reassessed.
角叉菜是一种地中海特有海藻，生长在非常浅的岩石基质上。它被认为是一种受到威胁的物种，经历了稳步下降，因此受到国际公约的保护。基于 467 篇文章和标本凭证，对该物种在法国地中海沿岸的历史分布进行了评估。我们通过实地调查，制作了一张关于其当前分布和丰度的精确地图，沿着 1832 公里的海岸线进行了调查。在 1125 公里的海岸线沿线观察到了角叉菜，其中包括 33%的几乎连续或连续的带。在其大部分分布范围内，没有损失的迹象，除了在普罗旺斯、法国里维埃拉和科西嘉的 4 个地区。我们发现角叉菜的缺失或低丰度与港口和大型污水排放口的附近有显著的关系。因此，应该重新评估该物种的保护状况。
