Clean Water and Native Plants

/0 Comments/in , /by

Article by Plant NOVA Natives; Image: https://jamesriverconsortium.org

If your property contains a stream, pond, or any sort of wetland, whether its flow is permanent or intermittent in nature, this article is especially for you! Anyone can directly enhance water quality, and in turn benefit the health of the animal, plant, and human communities that depend upon it, by using native plants to fill the “riparian buffer” adjacent to a water feature. The word “riparian” comes from a Latin word meaning “bank.” A riparian buffer protects the wetland from runoff from developed areas, including turfRegrass lawns.

If the riparian buffer already contains natural vegetation, you should first control any invasive plants found there.You should also avoid adding any new species, native or otherwise, that will disturb the existing plant community. You may need a waiver from your County to remove existing vegetation and to plant new plants within 100 feet of a stream, shore, or wetland. Maps of these “Resource Protection Areas” can be found here. If the area is currently landscaped or mowed, you may be able to add native plants without a waiver, but you should still check with your county or municipal government.

To figure out if the plants that are present are native or invasive, you can use a free app such as iNaturalist or a subscription-based app such as PictureThis to help you with the identification. You can also invite a volunteer from the Northern Virginia Bird Alliance Wildlife Sanctuary Program to walk the site with you.

Healthy riparian buffers with native plants are beautiful to see and fun to explore. They support a wide diversity of life and create peaceful and inviting landscapes that draw us in to enjoy and connect with the nature they support.

Riparian buffers are also the natural defenders of stream banks. They help stabilize the soil and control soil erosion. This is due to their capacity to slow down and absorb stormwater runoff that would otherwise erode the banks of streams and rivers and fill the Chesapeake Bay with excessive silt. Due to riparian buffer degradation and excessive runoff across Northern Virginia, a massive quantity of silt from our streams and rivers now reaches the Chesapeake where it clogs the gills of wildlife, smothers eggs, buries aquatic insect habitats, and interferes with the production of oxygen by aquatic plants. Anything we do that successfully holds soil will benefit the Bay. Riparian buffers also act as filters that trap pollutants. This protects aquatic life from harmful contaminants and keeps them out of our water supply. Native trees provide the leaves that feed aquatic insects, and their shade lowers the water temperatures, making the environment more hospitable for life. As the earth warms, planting and protecting native plants on riparian borders will become increasingly urgent.

Ideally a riparian buffer should be at least 100 feet wide, but don’t let that discourage you, as a buffer of any size is helpful. Try to pick combinations of native plants that would naturally occur along waterways in your region. This will increase the odds of creating a balanced healthy habitat that continues to grow and thrive. Please refer to the resources on the Plant NOVA Natives website to help you select your plants.

Riparian buffers formed naturally on undisturbed land, holding soil, cooling water, filtering pollutants, and supporting life. It is humans who have disturbed them. Our work now is to take a moment to pause and wonder at the interdependence of land, water, native plants, and animals. Regardless of the other forces at work to degrade our environment, we still have the power to rebuild essential habitats on the lands we control.

The Northern Virginia Soil and Water Conservation District (NVSWCD) monitors several streams throughout Fairfax County during their scheduled stream monitoring workshops throughout the year. These workshops engage volunteers in collecting data, with scheduled monitoring sessions at least twice a year at each location.

NVSWCD trains volunteers to assess ecological conditions in streams based on the absence/presence of benthic macroinvertebrates (aquatic bugs and other critters). Training includes field workshops and mentoring by experienced monitors, no prior experience required!

Volunteers can assist at different levels of commitment. You may choose to participate in one or a few NVSWCD public stream monitoring workshops, or you may become a certified stream monitor to adopt your chosen stream and commit to monitoring it at least twice a year.

There are three shifts scheduled thus far –

  • March 11, from 10am-1pm at Sugarland Run in Herndon
  • March 16, from 9am-12pm at Pohick Creek in Springfield
  • March 20, from 3-6pm at Difficult Run in Great Falls

Minimum age: 12  (All volunteers under 18 years of age must be accompanied by an adult.)

To sign up, please log in to Volunteer Fairfax and search for stream monitoring.

Detergents and Stream Environments

Article and photos by FMN Stephen Tzikas

During your outdoor activities, you may have seen soap suds in a trail stream.  While there is some environmental concern about them, their science is interesting.

My first professional exposure to detergents was with my first career project in 1985, at an environmental closure of the General Aniline & Film (GAF) plant in Linden, NJ.  I had the task, among other things, of testing, classifying, and preparing various detergents and surfactants for proper disposal.  The company, founded in 1886, had its origins as the German IG Farben firm whose assets were seized as enemy property in 1941.  When I see suds in a stream, I always remember the project at GAF.

Detergents are used for many purposes, but they can easily get

Surface Tension at the Turquoise Trail stream in Reston. Detergents lower the surface tension of the water, making it hard for aquatic insects like water striders to float on the surface.  They can leave fish and other critters starved for air. Detergent binds up oxygen to form bubbles.

into freshwater ecosystems.  Detergents are organic compounds, which have both polar and non-polar characteristics. There are two kinds of detergents: phosphate detergents and surfactant detergents. Detergents that contain phosphates are caustic, and surfactant detergents are toxic. Surfactant detergents are used to enhance wetting, foaming, dispersing and emulsifying properties. Phosphate detergents are used to soften hard water and help suspend dirt in water. Detergents, including biodegradable ones, can be poisonous to aquatic life. They can destroy the external mucus layers that protect the fish from bacteria and parasites. Most fish will die when detergent concentrations approach 15 parts per million, and concentrations as low as 5 ppm will kill fish eggs. Surfactant detergents can affect the breeding ability of aquatic organisms. Detergents also lower the surface tension of the water, which impacts some aquatic life.  Phosphate detergents can lead to freshwater algal blooms that release toxins and deplete oxygen.

Soaps and detergents are made from long molecules that contain a head and a tail. The diagram below represents a surfactant molecule. The head of the molecule is attracted to water (hydrophilic) and the tail is attracted to grease and dirt (hydrophobic). When the detergent molecules meet grease on clothes, the tails are drawn into the grease but the heads still remain in the water. The attractive forces between the head groups and the water are so strong that the grease is lifted away. The blob of grease is now surrounded by detergent molecules and washed away. The detergent molecules also help to make the washing process more effective by reducing the surface tension of the water.

How Detergents Work (Snapshot excerpted by author from https://molview.org with a search on sodium o-dodecylbenzenesulfonate.) The long chain of the sodium o-dodecylbenzene-sulfonate molecule is “grease-loving” while the cyclic part is “water-loving.”

Emerging stream concerns include another type of foamy substance.  This is a group of manufactured compounds known as per- and polyfluoroalkyl substances (PFAS). PFAS have broad uses in commercial products such as food packaging, nonstick coatings, and firefighting foam. Conventional wastewater treatment plants do not effectively remove PFAS. The PFAS concentration lifetime advisory is 70ng/L for perfluorooctanoate (PFOA).

In Fairfax County, the storm drainage system is separate from the sanitary sewer system. Storm drains convey stormwater runoff directly to local streams. Car wash water may contain oils, greases, detergents and other materials that pollute water and harm wildlife that live in streams. In Fairfax County, commercial car washes must be equipped with water recycling systems and discharged to the sanitary sewer system.  Individual residential car washing is exempt from this regulation. You can help by washing cars in an area away from storm drains. Use the minimum amount of detergent necessary, and use products that are biodegradable, phosphate-free, water-based, and pH neutral.

What About the Turtles?

/in , /by

During construction projects in Northern Virginia that include deforestation, the sites are required to have perimeter erosion control measures, often black plastic silt fence, often reinforced with chain link. Most of the displaced wildlife can escape by climbing, jumping, or flying out, but what about the turtles? Eastern box turtles often get barricaded in where they exhaust themselves trying to escape, desiccate in the sun, or get eaten by roving predators.

Tanya Finch, a Virginia Master Naturalist with the Banshee Reeks chapter, started What About

the Turtles? (formerly Tanya’s Turtle Project) in 2021. They work with construction contractors to gain access to construction sites and have volunteers walk the perimeter in search of critters that need a helping hand. They work with A.E.R.O. Animal Rescue for any injured wildlife and K2C Wildlife for assistance with venomous snakes we may encounter. They give presentations to local community groups on their important work, and how everyone can get involved.

In 2024, they saved 177 creatures including multiple species of turtles, 2 species of snakes, and a great blue heron from construction sites. This is thanks to including aquatic turtles in our efforts, rather than just terrestrial box turtles. If you see new construction sites, please email Tanya at [email protected] the location so she can see about coordinating a site walk.

Virtual
FEE: $15 member; $25 non-member

REGISTRATION

Event Sponsored by the Northern Virginia Bird Alliance (NVBA)

Between 2019 and 2022, the speaker completed five field trips in search of Hudsonian Godwits. Beehler visited stop-over sites through the Great Plains; visited breeding habitat in western Alaska, Churchill, Manitoba, and the High Arctic of western Canada; and did field surveys at a famous autumn staging site in James Bay. In all, Beehler traveled solo by car more than 30,000 miles, encountering Hudsonian Godwits in 10 states and provinces. He also spent time with Marbled and Bar-tailed Godwits, and 33 additional shorebird species. Moreover, Beehler accompanied various shorebird fieldworkers as they studied godwits and other species in remote and iconic field sites. In this illustrated lecture, Beehler will recount the highlights of his more than five months in the field, from Nome and Point Barrow to Tuktoyaktuk, Moosonee, and Monomoy Island.

Bruce Beehler is an ornithologist, conservationist, and naturalist. He is currently a Research Associate in the Division of Birds at the National Museum of Natural History, Smithsonian Institution, and a Scientific Affiliate of the American Bird Conservancy. Beehler has spent much of his scientific career studying and conserving birds and their forest habitats. After conducting doctoral fieldwork in Papua New Guinea, Beehler worked for ten years at the Smithsonian’s National Museum of Natural History, followed by stints at the Wildlife Conservation Society, U.S. Department of State, Conservation International, and the National Fish & Wildlife Foundation.
