The following parrotfeather profile (as well as many other aquatic invasive species profiles) can be found in the Lakes SOS app.
Other Common Name(s): Brazilian Watermilfoil; Parrot Feather; Parrot Feather Watermilfoil; Parrot’s-feather; Water-feather
Origin: South America
Habit: Aquatic and submersed perennial herb
Leaves: Emergent: Bright green; waxy; 1 - 2 inches (2 - 5 cm); stiffer and darker green than submersed leaves; can grow 1 foot (30 cm) above the surface; feathery; resemble small pine trees; Submersed: Limp; commonly mistaken for Eurasian milfoil; arranged in whorls of 4 - 6 leaves around the stem, each leaf having 20 - 30 leaflets
Stems: Stout; elongate; suspended in the water column or floating; reddish; adventitious roots form along the stem
Flowers: Inconspicuous; white; formed at the axils of emergent leaves; approximately 1/16 inch (0.15 cm) long; flowers in spring and sometimes fall
Habitat: Along the edges of freshwater lakes; ponds; streams; canals; not usually found in fast moving waterbodies; can tolerate moderate water level fluctuations; may be found in water gardens and aquariums
How it Spreads: Plant and root fragments spread by flooding, animals and boat propellers; also spreads by intentional planting
Threat: Dense populations create mats that choke waterways and hamper recreation; disrupts the food web by choking out native vegetation needed by fish and other aquatic species; can contribute to increased mosquito populations
Other Information: Almost all plants are female, therefore reproduction by seed is not an issue in North America
It’s finally April, and although some areas are experiencing pretty significant weather events, this is the month we start looking forward to warmer weather, bird and amphibian migrations, animals emerging from hibernation or torpor, and all the wonders and excitement spring brings.
There is no better way to celebrate spring than to participate in Earth Day activities every April 22nd. Every year, we recognize and celebrate the incredible strides we’ve made in the United States in environmental protection from the very first Earth Day in 1970. We’ve enjoyed clean air, clean water and federal protection of our threatened and endangered species for almost a half a century.
This year will be a different experience and not exactly the celebration we’ve become accustomed to on Earth Day. On April 22nd, hundreds of Marches for Science will take place across the county. These peaceful protests are to show our support for science, scientific research and evidence-based policies. The current administration in Washington does not support science, which is both dangerous and irresponsible. We hope you all feel the need to come together to support science and choose to participate in a march. Check out the March for Science website for organized marches in every state.
