2015 Firefly Festival: Perfect Weather, Perfect Fun

by Caroline Haynes, ARMN volunteer


ARMN volunteers were well represented at another successful Firefly Festival at Fort C.F. Smith in Arlington on Sunday evening, June 28. Unlike previous festivals that were sticky and hot, the previous day’s rain and cooler temperatures made for a perfectly delightful summer evening. Children of all ages improved their insect ID skills at “Bug Bingo,” were transformed into their favorite insect by some artful face painting, learned to imitate the flash patterns of different species of fire flies, created some beautiful glow-in-the-dark firefly crafts––and, of course, caught and released lots and lots of fireflies. Those who participated in the nature walk at dusk were rewarded with a meadow light show as the fireflies began their nightly courtship. The almost-full moon and roasted marshmallows topped off a fun, educational, family-friendly evening.

A Visit to Blue Plains Advanced Waste Water Treatment Plant

ARMN member Louis Harrell reports on a group visit to Blue Plains. All came away with enhanced understanding of waste water treatment––and some valuable tips. 

By Louis Harrell, ARMN

On May 28, 13 ARMN members traveled to Southwest D.C. to the Blue Plains Advanced Waste Water Treatment Plant for a guided tour of the facility. Blue Plains is the largest plant of its kind in the world, with the ability to treat 370 million gallons a day. Peak capacity is slightly more than 1 billion gallons per day. The facility serves Loudoun County, Fairfax County, part of Arlington County, Montgomery County, Prince George’s County, and the District of Columbia.

We saw key features of the facility and met with an engineer who answered questions about the plant and informed us about issues that Blue Plains faces.

We saw the primary and secondary sedimentation tanks, the nitrification and denitrification tanks, and the location where cleaned water is returned to the Potomac. The nitrification tanks use microbes and a large amount of aeration to oxidize the nitrogen from ammonia to nitrate. The denitrification tanks are used to convert the nitrate to nitrogen gas using microbes and methanol. Unlike the nitrification process, the denitrification tanks do not use aeration. The nitrification and denitrification steps, along with a final disinfection step, make Blue Plains into a highly advanced facility. Our guide showed us samples of the effluent and drinking water and we agreed that they both looked the same.

Some of the takeaways from our visit included:

  • Blue Plains plans to start using methane captured on site to produce 10 MW of their power requirements. DC Water is the single largest consumer of electricity in the District.
  • The plant produces Class A biosolids, which are presently distributed locally for free to community gardens; in the next few years they hope to market them commercially. This change will allow the plant to reduce its carbon footprint by one third.
  • We learned that flushable baby wipes should not actually be flushed as they clog the pipes at the plant. Composting was also recommended.

Bees of Singular Tastes and the Plants They Love

by Sherrie Burson and Brooke Alexander, ARMN

Sam Droege, a scientist at the Patuxent Wildlife Research Center, entertained and educated ARMN volunteers and members of the public on May 11 in a talk at the Arlington Central Library. Droege works on the design and development of status and trends data for U.S. plants and animals. Currently, he is swept up in surveys for native bees.

Droege shared research from a soon-to-be-published paper he co-authored with Jarrod Fowler that lists plant genera and the native specialist bees that need them. He explained that specialist bees have more finicky needs than generalist species. Generalist bees are out all season, have higher population levels, and can handle disturbed sites. In contrast, specialist bees are out for an average of five weeks, have lower overall population levels, and are good indicators of quality habitat. Of the bees that carry pollen (not all do––parasitic bees, for example,) specialist bees feed their young from a limited range of one to three plant genera. Native bee specialists tend to visit perennial plants commonly found in vernal woodlands (ephemerals), summer composite communities, and ericaceous (plants in a family that includes blueberries) heaths.

Droege dazzled the audience with photographs of flowers and the bees that frequent them, describing their interactions. In response to a question about cultivars, Droege said that initial research performed at the Mt. Cuba Center, a horticultural institution in northern Delaware, and by the New England Wild Flower Society shows that cultivars are less attractive to bees. However, planting native species is a known benefit to native bees.

Droege and Fowler’s paper includes a list of plants that native bee specialists find particularly appealing. The list includes a number of native plants that are not commonly planted in local yards. Droege encouraged the audience to consider planting some of these species to support the bees that need them.

The following table lists genera and common names for a host of native plants that thrive in our area. Most of them should be available from the Earth Sangha plant nursery in Springfield ( or from the Potowmack Chapter of the Virginia Native Plant Society at Green Spring Gardens in Alexandria (

Planting species that native bees depend on is one important strategy to help save these important pollinators. Another is to provide patches of bare ground for ground-nesting bees. These kinds of measures, when practiced widely by homeowners and caretakers of community landscapes, go a long way toward ensuring the continued––and critical–– presence of native bees in our ecosystems.

ARMN Member Mary McLean Wins Bill Thomas Award


Mary McLean in Tuckahoe Park

The Arlington Regional Master Naturalists proudly announce that on April 21, 2015, ARMN member Mary McLean was named a recipient of the Bill Thomas Outstanding Park Service Volunteer Award for her work in 2014.

McLean is a steward at Tuckahoe Park in Arlington and her specialty is invasive plants. Since the early 2000s, she has enlisted the help of neighbors, volunteer and school groups, and many others to transform the park and educate them on how to spot a non-native plant species. As a result, Tuckahoe has benefitted from a significant decline in non-native, invasive species, restored health of the native trees, and the return of native shrubs and ground cover.

In addition, McLean has also conducted focused tours and presentations on Tuckahoe Park’s underground stream and other ecological wonders to help educate and motivate others to join in the beautification effort. She also has volunteered at and served professionally as the Outdoor Learning Coordinator at Tuckahoe Elementary School. In those roles, she has worked with teachers, volunteers, and students in Tuckahoe Park on restoring habitat, planting natives, controlling erosion, and learning the natural history of the park.

Virginia Master Naturalists Celebrate 10 Years

In the past 10 years, the Virginia Master Naturalist program, which includes the ARMN chapter, has trained more than 3,000 Master Naturalists who have contributed more than half a million volunteer hours. Read more about this amazing decade of stewardship, education, citizen science, and conservation.

BLACKSBURG, Va., April 9, 2015 – This year marks the 10th anniversary of the Virginia Master Naturalist program. In the decade since the national program started in the Commonwealth, the organization has trained several thousand Master Naturalists, who have contributed 526,583 hours of volunteer service — the equivalent of well over 250 years of full-time employment.

Master Naturalists have installed bluebird birdhouses, counted monarch butterflies, built forest trails, helped schoolchildren plant wildflowers, yanked invasive species from parklands, and much more. Their work, which provides education, outreach, and service to support Virginia’s natural resources and public lands, is calculated to be worth nearly $12.4 million to date, said Alycia Crall, program coordinator.

“Close to 3,500 Master Naturalists have been trained since the program began in Virginia,” Crall said. “Many of them are still active volunteers, donating at least 40 hours of work each year.”

On the average, each active volunteer reaches more than 70 youth and adults annually through educational programs or informal projects. Master Naturalists have contributed to more than 70 scientific studies, advancing knowledge about Virginia’s natural resources. Study subjects have ranged from frogs to American chestnuts to spring beauty flowers to osprey. Master Naturalists have cared for more than 2,500 acres of public lands by removing non-native species, maintaining trails, and planting native flowers.

The organization has grown from an initial 10 chapters to 29, each making a significant positive impact on Virginia’s natural resources. The Virginia Master Naturalist program is open to anyone who wants to learn more about nature. While participation is limited to those 18 or older (or at least 14 years old when accompanied by an adult), many chapters offer Junior Master Naturalist programs for younger children through 4-H clubs or schools.

Participants learn basic ecology and scientific principles as well as ornithology, geology, botany, zoology. They start out by completing 40 hours of basic training offered through a local chapter. An additional eight hours of advanced training are required each year.

“I like marking the seasons by seeing what’s happening out there,” said Brenda Graff, a master naturalist in Christiansburg. “I especially like collecting data that can help the environment.”

Virginia Master Naturalist Program is jointly sponsored by the Virginia Cooperative Extension and the Virginia departments of Conservation and Recreation, Environmental Quality, Forestry, and Game and Inland Fisheries, as well as the Virginia Museum of Natural History. The program is based in the Department of Forest Resources and Environmental Conservation in Virginia Tech’s College of Natural Resources and Environment.

The College of Natural Resources and Environment at Virginia Tech, which consistently ranks among the top three programs of its kind in the nation, advances the science of sustainability. Programs prepare the future generation of leaders to address the complex natural resources issues facing the planet. World-class faculty lead transformational research that complements the student learning experience and impacts citizens and communities across the globe on sustainability issues, especially as they pertain to water, climate, fisheries, wildlife, forestry, sustainable biomaterials, ecosystems, and geography. As a land-grant university, Virginia Tech serves the Commonwealth of Virginia in teaching, research, and Virginia Cooperative Extension.

Time to Think About Spring Planting: This Year, Plant Natives!

by Kasha Helget, ARMN Communications Chair


Scarlet Bee Balm (Monarda didyma)

Why plant natives?

As described by the USDA, native plants are adapted to the local climate and soil conditions where they naturally occur. They also are critical sources of nectar, pollen, and seeds that provide food for native butterflies, insects, birds, and other animals.

Native plants are also advantageous, because they:

  • do not require fertilizers and require fewer pesticides than lawns.
  • need less water than lawns and help prevent erosion.
  • help reduce air pollution.
  • provide shelter and food for wildlife.
  • promote biodiversity and stewardship of our natural heritage.
  • are beautiful and increase scenic values!
