Big Thank You to Founder Marilyn Schroeder

/in , /by

The Fairfax Chapter (FMN) has one official Cooperative Agreement (CA). A mutual agreement between FMN and Fairfax County Park Authority (FCPA) agreeing to provide mutually beneficial resources. The CA was originally signed in 2007 with a revised version of the CA was signed in 2022 by VCE Exec Dir. Micheal Cutter (for FMN) and FCPA Jai Cole, Executive Director FCPA.

As Chair of the Fairfax Chapter’s Coordinating Committee, Marilyn Schroeder drafted the original CA when the FMN charter was established in 2007. She then represented FMN as the liaison until June 2025 when she passed the reins to another FMN volunteer. At the chapter membership meeting in June, FMN recognized Marilyn’s 18 years coordinating the meat and marginalia of FCPA activities – applying for field permits, identifying volunteer opportunities, providing FCPA trainers for FMN classes, and a myriad of other detailed responsibilities in coordination with other FMN Committees. Annually, FMN contributes more service hours towards FCPA activities than to any other single FMN chapter associate. 

Even though Marilyn will continue to volunteer in other FMN activities, it is with much gratitude that we sincerely give thanks for her many years of specific service as the liaison. She was previously honored as an FMN Trailblazer for her significant contributions in establishing the FMN chapter in 2007 – drafting initial By-laws and Operating Manual, and serving in several board positions over the years.

Katy Johnson is the new FCPA/FMN liaison.

FCPA 2025 Outstanding Volunteer Awards

/in , /by

As announced by FCPA at its meeting on May 28, the Fairfax County Park Authority Board approved a resolution honoring 20 individuals as 2025 Outstanding Volunteers. These peer-nominated individuals were recognized for their dedication to community and their invaluable service to the Fairfax County park system.

Of the twenty, two Fairfax Chapter Master Naturalist volunteers were officially recognized:
* Jean Lockhart, Hidden Oaks Nature Center, Front Desk
* Elizabeth Train, Huntley Meadows Park, Roving Naturalist/General Support
The Board stated that more than 10,000 volunteers contributed to the operation, preservation and conservation of Fairfax County parks in Fiscal Year 2025. They contributed 116,005 hours of volunteer service and their work is valued at over $3.88 million. The Park Authority could not function without the support and commitment of our volunteer force.
“Our parks meet the highest standard of beauty, safety, and accessibility in large part due to our volunteers. Their skill and passion, whether repairing trails, planting trees, or educating visitors, elevate every acre, every day,” said Park Authority Executive Director Jai Cole.

Jean, a relatively new VMN (2023), contributed hours as volunteer on duty, nature program leader, and bird counts. Liz, a VMN since 2019, is involved with just about every volunteer role possible at Huntley Meadows Park. They are both very deserving of this recognition.

The Park Authority, joined by Fairfax County Board of Supervisors honored all of its amazing volunteers with a special evening of music and celebration at the Volunteer Appreciation Night on Thursday, July 10, as part of the Government Center’s ‘Evenings on the Ellipse’ Summer Concert Series.

And The Emmy Goes To …

… FMN Kathryn Pasternak for the Outdoors Maryland segment titled “Ghost Rivers”. Ghost Rivers tells the story of Sumwalt Run, a stream that once flowed through Baltimore’s Remington neighborhood. In the early 20th century it was buried in a brick and concrete culvert up to 40 feet below street level. The same fate as natural streams in cities throughout the world, including a network of streams in Arlington, Alexandria, and Washington, D.C. – But I digress.

Artist Bruce Willen memorialized Sumwalt Run by tracing its path through the neighborhood, marking it with a sinuous blue line and adding educational markers that tell the environmental, cultural and historical story of the stream along the path it takes all the way to the Jones Falls, and then out to the Chesapeake Bay.  Kathryn and the team worked with Bruce filming the final stages of the Ghost Rivers public art installation, and accompanied him on a walking tour he gives with local residents. They also filmed the Baltimore Department of Public Works inspecting the interior of the Sumwalt Run culvert using a crawler camera, and then doing water testing at the outflow of Sumwalt Run at Jones Falls.

The Outdoors Maryland Episode received the Emmy Award and like all their episodes, it has three stories. The 3 stories stitched together in Episode 3603 each have a different theme about water. Series Producer Stefanie Robey describes it this way: It was a Bay/water themed episode, with stories about submerged aquatic vegetation restoration work, open-water swimming, and the Ghost Rivers project.

Kathryn thinks part of what helped them win was that the episode told stories about water from three totally different perspectives — a more science/restoration focused piece, a recreation focused piece, and then a historical/cultural/arts focused piece with Ghost Rivers. Kathryn’s segment starts at the 9:45 mark of the episode and runs to the 18 minute mark. But the entire episode is interesting.

Eight months work for eight minutes of video. That’s tenacity. The episode won for Science/Environment Long Form.  (Watch here: Outdoors Maryland, scroll down to Episode 3603).

Kathryn (Pasternak Media) became an FMN in 2021 but she is also a veteran of wildlife, conservation, and cultural films; and recipient of two National Emmy Awards for ‘Best Science and Nature Program’. She spent 15+ years at National Geographic Television working on high-end programs for international distribution. Since 2007, she’s been producing media independently both as a freelancer and small business owner.

Beech Leaf Disease (BLD)

The following Information comes from the Urban Forest Management Division Annual Report Fiscal Year 2024, Released April 2025

Beech Leaf Disease (BLD)

What is it?
BLD, a relatively new disease of native American beech as well as other
Fagus/beech species, is caused by a foliar-feeding nematode (a
microscopic roundworm). The nematodes enter the tree’s leaf buds in
the fall where they overwinter, multiply, and feed on newly forming
leaf tissues. The nematodes further multiply and spread throughout
the tree from year to year until leaf buds no longer produce leaves.
As healthy foliage decreases, the tree’s energy, nutrient, and water
uptake decreases, and the tree eventually dies.
Why is it a problem?
Beech trees are critical to the native forest ecosystem, providing
food for a wide variety of wildlife, and bearing nutrient-rich fruit with
seeds that last through the winter and serve as a food source when
other plants have long stopped producing. There are approximately 4.3
million beech trees in Fairfax County, making them tied with red maple
for the County’s most common tree species. BLD, nearly 100% fatal,
is spreading rapidly; and there is no known safe treatment option for
forested environments.
What is being done?
County staff achieved the following results and milestones in FY 2024:
 Mapped 6 infestations totaling 60 acres at regional and County parks (previously 13 acres in FY 2023).
 Established 4 monitoring plots in beech stands confirmed to have, or at high risk of developing, BLD.
 Participated in a comprehensive U.S. Department of Agriculture (USDA) Forest Service study spanning the full geographic reach of
both BLD and beech bark disease.
 Hosted a webinar—“Unraveling the Mystery”—in partnership with Virginia Cooperative Extension (VCE) to raise awareness.
 Contributed BLD samples for a regional nematode DNA study out of the University of Connecticut.
How YOU can help!
– First, learn to IDENTIFY early symptoms of the disease, infected leaves, and other diseases that can appear like BLD.
– REPORT sightings on iNaturalist, an easy-to-use app that shares information with community scientists.
– And finally, PRACTICE good tree care such as proper mulching and watering during droughts; and be considerate and responsible when it
comes to selecting soil treatments and other landscaping services.

Pollinator Pathways: Connecting your yard to the bigger picture

Article by Eileen Ellsworth

Imagine the world as it once was. Verdant forests, buzzing meadows, and numerous other natural areas were immense, whole, and pulsing with life. Over time, human activity emerged and carved the natural world into disconnected, even isolated parts. Ecologists refer to this process as habitat fragmentation. You can see it in urban settings where green parks are biological islands surrounded by buildings and concrete roads. You can see it in rural settings where agriculture simplifies ecosystems and amplifies the populations of only certain insects to the detriment of others. You can see it in suburban settings where developments destroy natural habitats and where landscapes are “replaced” with all non-native species.

Large and mostly undisturbed ecosystems can still be found, of course, especially in our beloved national parks and forests. But even they are distant from each other, understaffed, and too small in total acreage to sustain the biodiversity of the continent. Any solution to the problem of habitat fragmentation and the resulting loss of biodiversity, therefore, must be found right here among the throng of human life – where we live, work and play.

Is it possible to reconnect isolated fragments in our urban, suburban, and rural settings to benefit pollinators and the creatures that depend upon them? That was the question that sparked the “pollinator pathway” concept in 2007 by Sarah Bergmann, an artist living in Seattle. As part of a social and ecological project, she envisioned and described a network of native gardens that could create a “pathway” to support pollinators. This core idea led to the creation of a nonprofit – Pollinator Pathway – by Donna Merrill, a conservationist from Wilton, Connecticut, in 2017. Since then, the group has helped inspire and launch a national movement.

The idea is a powerful one. Anybody can take part, even at a novice level. There are very few barriers to participation. If all you have is one native tree or a  small pollinator garden – preferably one with some native plants – it’s a start, and you can build from there.

The main goal of a pollinator pathway is to reinstate connectivity between several small but healthy habitats. A single native tree can support bees and other pollinators as much if not more than a flower garden. Building a pollinator pathway on your street, for example, may include adding a new native tree or two, or creating new healthy gardens on communal grounds or private property as “stepping stones” along the way. It may include the expansion of existing native plant areas. Removal of invasives that disrupt the pathway will certainly be part of the plan, along with pledges to avoid all broadcast pesticides including mosquito and tick sprays. Only unpoisoned ecosystems can be included in the work.

Many communities across America are already building pollinator pathways and proving the concept. You can recruit participants on your own, or have fun working with like-minded people to muster engagement. Hold a kick-off meeting to build some early momentum. Don’t over plan. Take some early action, starting with 1 or 2 easy planting projects, then see where it takes you.

On a new webpage just launched by Plant NOVA Natives you will find some handy tools to help you build a pollinator pathway in your neighborhood or community. They include:

  • A tip sheet for pollinator pathway organizers
  • Instructions for ordering medallion signs that will be delivered to your house from Plant NOVA Natives for you and your participants. If you are in Northern Virginia, we will have the sign company mail you the first five for free.
  • Ideas for how to pitch the idea to the folks you want to engage
  • Pollinator Pathway handouts to leave with your neighbor.

Join the movement! Let’s work with our neighbors and friends to connect the fragments, rebuild some beneficial habitats, and heal the everyday ecosystems that surround us. Their resilience is astonishing. New life, activity, and hope will certainly emerge, along with a new joy in being part of something much bigger than our own backyards.

Photo: FMN Mary Ann Bush, FMN Spring Grads – June162025

On Monday June 16, we proudly celebrated the graduation of a passionate and dedicated group of students from our Master Naturalist Basic training program. What began as a shared curiosity about the natural world has transformed into a community of informed and enthusiastic stewards of our local environment.

Over the past several months, these individuals immersed themselves in both classroom learning, and field trips which facilitated hands-on, experiential learning opportunities outside of the classroom. They learned not only about native ecosystems and species, but also how to be a part of natural resource conservation in the community

Graduation is more than a milestone—it’s a beginning. These new graduates are now equipped and eager to take on a wide range of volunteer opportunities: leading nature hikes, restoring habitats, monitoring wildlife, educating the public, and much more. Each graduate brings a unique voice and skillset, and together they form a force for good in our natural communities.

To our newest graduates, we can’t wait to see where your curiosity, compassion, and commitment take you next!

Here are the 2025 Spring FMN Basic Training Graduates:
Alsegaf, Kathy
Baucom, Celeste
Borghi, Aurora
Bretz, Kevin
Colby, Charles
Curley, Christina
De Nardi, Mia
Edwards, Eren
Grass, Nancy
Gravatt, Peyton
Newberry, Tucker
Racine, “Anna Virginia “”Hope”””
Racine, James
Smyth, Trish
Zavala, Andy
Malcolm Macniel
Elliff, Rachel

A thought provoking prose to encourage this tour is Charles Dickens’ luminous writing about the beauty of the natural world – “The freshness of the day, the singing of the birds, the beauty of the waving grass, the deep green leaves, the wild flowers, and the thousand exquisite scents and sounds that floated in the air— deep joys to most of us, but even more so to those whose life is in a crowd or who live solitarily in great cities as in the bucket of a human well—sunk into their breasts and made them very glad.”

As you push off from the shore, inhale deeply, relax, immerse yourself in the natural world, and become “very glad”.

Katy Johnson – The New FMN Liaison to FCPA

/in , /by

As many readers already know, FMN has maintained a signed Cooperative Agreement (CA) with Fairfax County Park Authority (FCPA) since chapter inception in 2007. Annually, FMN contributes more collective volunteer hours towards FCPA Activity Codes than any other single partner organization.
In turn, FCPA provides FMN with course instructors, meeting facilities, volunteer opportunities, and access to parks for field trips and CE hikes.
In 2024, FMN reported over 5300 volunteer hours at 12 individual FCPA sites.

The CA identifies liaison roles and responsibilities for both FCPA and FMN. Together the liaisons coordinate activities, acquire field trip permits, identify opportunities, and maintain open communications between the orgs. Currently, Tammy Schwab is the FCPA liaison and Katy Johnson is the newly designated FMN liaison. Katy takes over from Marilyn Schroeder who held the FMN role since 2007, when she helped establish the initial CA.

Katy graduated FMN training in 2021. Since then she has contributed over 600 service hours and is also the POC for FMN activities in Fairfax City. She is very familiar with the functional liaison responsibilities defined in the CA by virtue of her similar role in another local organization, Northern Virginia Mineral Club. Katy joined NVMC and FMN because she believes in their missions – to educate and spread an understanding of the importance of natural resources in our everyday lives.

Going forward please direct questions regarding FCPA opportunities to Katy

FMN Katy Johnson rockhounding – photo Katy Johnson

(katynor@gmail.com). FMN has 10 individually defined Activity Codes for FCPA. We look forward to continuing our long time association with Fairfax County Parks. Thank you Katy!

FYI – Additional Chapter Partners:
The formal CA with FCPA is the only signed agreement our chapter maintains. We do, however, have other Chapter Partners and we strive to identify points of contact for each of them in their corresponding BI Activity Code descriptions.
For example, FMN service hours for Fairfax Tree Stewards may be recorded using Activity Code S405. The FMN POC for FTS is found in the S405 Activity Code description in BI, along with additional details so you may ask questions of someone directly involved with that organization.

The FMN web site lists several chapter partners and links to their sites for general information. FMN POCs and specific FMN Activity details will normally only be found in the BI Activity Code Description, as described above for S405.

Of course if all else fails, please direct activity code catalog and CE questions to the Hours/CE co-chairs and we will work with you to clear the fog.
Hours/CE email – FMNcontinuingED@gmail.com
