context_page_description: Callitriche stagnalis is a perennial aquatic vascular plant species. Also known as pond water-starwort, C. stagnalis, may thrive in a variety of aquatic and subaquatic habitats, specially those exhibiting slowly moving to non-moving water. Although C. stagnalis does not pose a threat to humans, its reproductive rate may pose a threat to native vegetation. Resulting dense vegetative mats frequently out-compete species in native communities.
context_section_description: Although this species does not pose a threat to humans, it has the potential to threaten native and other local vegetation. Due to this species ability to reproduce by clonal spread, C. stagnalis can form thick and locally dense vegetative mats which can crowd out other vegetation by taking up limited space and nutrients in the environment.
