About Callitriche stagnalis Scop.
Callitriche stagnalis Scop., commonly called pond water-starwort, is a species of perennial aquatic vascular plant. It can grow well in a wide range of aquatic and subaquatic habitats, especially those with slow-moving or still water. While C. stagnalis is not harmful to humans, its high reproductive rate can threaten native vegetation in regions where it has been introduced. Dense vegetative mats formed by this species often outcompete native plant species.
C. stagnalis typically occurs in aquatic environments with little to no water movement. It is commonly found in lakes, ponds, salt marshes, and slow-moving rivers and streams, and it can thrive in both fresh and brackish water habitats.
The species is native to Europe and North Africa, where it is widespread across local aquatic and subaquatic habitats. Today, C. stagnalis has been recorded in Europe, Northern Africa, the United States, Asia, Australia, New Caledonia, and New Zealand.
