Her research this summer is on the nexus of biodiversity and water resources. Her earlier NWNL blogs were: Wild Salmon v Hatchery Salmon and Buffalo,…

What are Phragmites and why are they a Problem?

Non-native Phragmites, also known as common reed, is a perennial, aggressive wetland grass that displaces native plant and animal species. Invasive Phragmites is one of the most widespread plants on Earth and is found worldwide. In the U.S. it grows in the eastern states particularly along the Atlantic Coast and increasingly across the Midwest and…

Even invasive species can be beautiful

Water hyacinth (Eichhornia crassipes) is one of the world's worst aquatic weeds. It is characterized by rapid growth rate, extensive reproductive output and broad environmental resistance. It creates dense mats of vegetation that restrict oxygen in water, causing deterioration in water quality, fish mortality and declining biodiversity. A healthy acre of the plant can weigh…
