Are too many deer endangering our local flora and fauna? If so, what can be done about it?

As humans have transformed landscapes, many species have lost their habitats, struggling to survive, while whitetailed deer have thrived. Overwhelming evidence points to high deer populations as a main factor in reducing
biodiversity and limiting forest regeneration. Cornell University Professor Blossey, a leading expert on forest health in
the Eastern United States, will present evidence for this imbalance and discuss potential solutions. “Deer are
charismatic native species that belong in our fields and forests,” Blossey said. “Humans have allowed them to become
ecological bullies, and if we are serious about our responsibilities to protect all native species, we need to embrace the
need to reduce deer impacts through reductions in the local deer herds.” This presentation, sponsored by a network of
Northern Virginia environmental organizations, comes as Arlington County studies the impact of deer.

A Look Behind the Curtains – Project Codes

Cover photo: Jerry Nissley

As experienced FMN volunteers most of us have logged into Better Impact (BI) to record hours of service or CE. Because of this, from time to time the Projects/Hours Committee receives questions via [email protected] asking about how to record hours or how to best identify service codes to use for a given project. Given that there are those occasional questions and that there have been some subtle changes to BI over time, we thought a behind the curtains look into the intricacies of FMN Project Codes may be helpful. So strap in and welcome to the most exciting ride of your life through the wild kingdom of Project Codes. [Exciting ride? Isn’t that a little over the top? Ok that’s probably gratuitous-hype but who’s going to read a boring article on ‘process and policy’? Bleh. Let’s move along.]

At chapter inception, FMN developed and continues to maintain a service/project catalogue in accordance with reporting requirements and responsibilities that all chapters have to state level VMN. The FMN catalogue lists all approved FMN projects and it is required by VMN in order to maintain insurance liabilities in case of incidents while volunteering. By recording hours in a timely fashion, the FMN volunteer provides partial but verifiable evidence to help VMN protect the volunteer in case there is an incident. Accumulated hours, reported annually to VMN, also support our sponsor agencies by providing documentation that benefits their funding profiles. The Project Catalog may also be considered a valuable, readable list of FMN volunteer opportunities organized by areas of interest. It is an informative resource at your fingertips to provide legit ideas to fuel your volunteer cravings. It’s better than ice cream! [Whoa… hold on there partner … better than ice cream? Ok, I give. That is a ridiculous thought. Let’s continue.]

As an organizing construct, FMN has nine project categories and one CE component:
1. Admin
2. Birds
3. Community Outreach
4. Habitat creation and restoration
5. Native plants and invasive removal
6. Parks
7. School Engagements
8. Water and wetlands
9. Wildlife Surveys
CE = All Continuing Education

Project codes are further classified as either Citizen Science, Education/Outreach, or Stewardship. Project codes beginning with C = Citizen Science; codes beginning with E = Education/Outreach; and codes beginning with S = Stewardship. C, E, or S codes are distributed throughout the FMN Categories (except for Admin and CE) depending on the project description and purpose.
The four-part Project Code was developed by the FMN IT team. This format allows codes to be correctly cataloged and supports automated extraction of data for annual reporting requirements. The parts are:
1. FMN category – | 2. Project Code: | 3. Project Title – – | 4. Project Org

FMN category – Project Code: Project Title – – Project Org

Here are 3 examples:
Parks – C106: FCPA Citizen Science Programs — Fairfax County Park Authority (FCPA)
Project code C106 covers most citizen science projects on park property sponsored by FCPA for which FMN volunteers may contribute hours as identified in the project description .

Community Outreach – E543: Education and Outreach — FMN
Project Code E543 is for educational, community outreach project hours (tabling, teaching, instructing) contributed by FMN volunteers as defined in the project description.

Native plants and invasive removal – S861: Plant NoVA Trees – – Department of Forestry (VDoF)
Project Code S861 identifies stewardship projects organized by the organization Plant NoVA Trees for the physical planting of native plants or removal of invasive plants for which FMN contributes hours. VDoF is a sponsor of Plant NoVA Trees and VMN and the project org.

Project Org (part 4) is the value entered into the Project Organization field, which is the last required field in the template when recording service hours. [Wait, what? So you never have to guess at what to enter? That’s right.  Just copy that value in as the Project Organization and be done. Let’s move along. The article is getting way too long; we’re losing readers; almost done.]

New projects may be requested by FMN volunteers at any time by submitting a Project Proposal form. The form is available on the VMN web site buried in their vast reference libraries, so it is easier to request a form by emailing a request to [email protected]. The Hours Committee will send a blank form and a pre-filled sample form for guidance –  [no questions asked, he says sotto voce]. Once the form is returned, the Projects/Hours Committee will review it to make sure the project does not fall under the purview of an existing project. If the project is deemed unique, it will be evaluated for approval. [At which time questions will be asked? Yes. That’s what we do. But we do it for you. Hey – that could be a Projects/Hours Committee logo or catch phrase; bumper stickers, hats. Stop it! Just end the article already!]

There you have it – a peek into the BI project code structure as tailored by FMN. Of course, the Projects/Hours Committee will continue to be at your service to answer future questions, so fire away.

Responding to Misbehavior in Nature

Photo:  FMN Janet Quinn

Article by FMN Laura Handley

With all the time we Master Naturalists spend in nature, most of us have witnessed some sketchy behavior out there. Perhaps you’ve seen a lady digging trillium from the forest floor, or kids pulling the wings off insects, or young lovers carving their initials into the smooth bark of a beech tree. What are we to do in such a situation? Do we cringe and walk on, averting our eyes from the misbehavior? Are we obligated to jump in and put a stop to it?

Thankfully, not the latter. As Master Naturalists, we have no duty to act when we see someone messing with nature. We also have no enforcement authority, so we’d have no more standing than any other passersby to tell someone to stop what they’re doing. And unlike park rangers, we’re not trained to enforce park regulations. Our training includes many best practices for observing nature and moving through natural areas, but it doesn’t cover the rules that apply in any particular area. Rules can differ quite a bit from one park system to another: an activity that’s banned in one place might be perfectly fine elsewhere. (For instance, the Fairfax County Park Authority is adamantly against foraging for edible plants, but Sky Meadows State Park in Fauquier County allows visitors to gather small amounts to be consumed within the park, and some national forests even allow commercial harvesting with the right permit.)

What we are trained to do is understand nature and share our knowledge with others. And most misbehavior toward nature is rooted in a lack of either knowledge or empathy (which often arises from knowledge). It’s safe to assume that if someone makes the effort to visit a natural area, they value nature and wouldn’t want to ruin it; they often just don’t know that what they’re doing is bad, or bad enough to make a difference. And so our best response, when we see someone doing something that looks harmful, is to start a conversation and see if we can advise them better. (Of course, we should always be careful when approaching strangers; some people can get belligerent when questioned. Use your best judgment, and remember that it’s not worth risking your safety to intervene.)

A good way to start the conversation is with a friendly, open-ended question: “What are you doing there?” Give the person a chance to explain what they’re up to. It could be that you caught them at the worst-looking moment of something innocuous, such as trampling vegetation while trying to retrieve a lost ball. It could be that they don’t know they’re doing harm, such as by walking off-trail or collecting wild seeds indiscriminately without a plan to ensure those seeds germinate and thrive. It could even be that they think they’re helping when they’re actually doing harm, such as by killing bugs that pose no threat or cutting down native vines from trees. Or–ideally–it could be that they know exactly what they’re doing and are going about it in a legal and environmentally responsible way, such as foraging the berries of an invasive plant to keep that plant from spreading, or collecting a small sample of a local ecotype of a native plant to add to their garden in place of a nursery-grown strain from out of state. (I hope this last option becomes more common as people become more aware of ecological issues and the many productive interactions we can have with our local ecosystems!)

Once you’ve established a rapport with the person, and once you’ve learned what their goals are, you can help them find a more ecologically sound way to meet those goals. If those kids are feeling bored and destructive, you could steer them away from the poor innocent bugs and toward an invasive plant that needs removal. The trillium-gathering lady might not know that most woodland wildflowers require the soil chemistry and mycorrhizal symbionts of the forest floor; once she learns those plants will almost certainly die if transplanted elsewhere, she’d probably take your suggestion to leave them be and look instead for native plants that would thrive in a garden (especially if you point her toward resources and retailers like Plant NoVA Natives and Earth Sangha). And if the lovers want to memorialize their relationship, instead of scarring an older tree, why not plant a young one that can grow along with their love? In an ideal situation, everyone can leave satisfied; if not, at least the culprit will know better and you’ll have done all you can to share your knowledge and encourage better stewardship.

While you’re talking, I wouldn’t brandish the Master Naturalist credential to convey authority, but it’s not a bad idea to mention the program or the resources on our website, especially if the person seems interested in learning more. Who knows–maybe you’ve found a new applicant for the next Basic Training!

The Virginia Geological Field Conference

Article and photos by FMN Stephen Tzikas

Every autumn the Virginia Geological Field Conference (VGFC) provides geologists, university students, and the public an opportunity to participate in a geologic field excursion within the State. In 2022 the event was held November 11-12 and explored the Goochland Terrane, just west of Richmond, VA. Attendance levels usually necessitate the need for two coach buses to transport the participants to the various locations on the agenda. The event is usually hosted by universities, community colleges, and/or State organizations. The field experience is invaluable. The VGFC website provides the details and should be monitored:

These conferences and field trips are not just found in Virginia, but they are not available in every state. Fortunately for Virginia Master Naturalists, our neighboring States have very active programs as well:

I highly recommend these State excursions as learning experiences for Fairfax Master

This is one of the many outcrops at Hidden Rock Park in Goochland, VA. These leucogranite dikes display boudinage structure.

Naturalists, even though only the VGFC excursion is applicable as FMN CE training.*  I have been to several of these and they are excellent, especially the ones found in northern states offering glacial geology exploration opportunities.

There were plenty of boudins at visited locations in the 2022 VGFC site itinerary. A boudin is a geological term for structures formed by extension (stretching), forming sausage-shaped boudins.

Welcome Fairfax Tree Stewards

Cover photo: Public Domain

In January 2023, the FMN board approved a chapter partnership with Fairfax Tree Stewards (FTS). FTS is an educational, non-profit, volunteer organization providing specialized training and certification focusing on trees. It is a program under the auspices of Trees Virginia, registered with the state as Virginia Urban Forest Council and is a private, non-profit organization whose mission is to enhance the quality of life through the Stewardship of our Commonwealth’s urban and community trees. Founded in September 1990 and incorporated in June 1991, the organization works to promote an awareness of our community forests and the value of trees. Approved chapters, such as FTS, use the newly updated Manual to form the basis of training classes, and FTS will supplement book learning with hands on field classes on tree selection, tree planting, tree pruning and tree ID by season.
The first FTS certification class, scheduled for February 2023, is full and includes a few FMNs. FTS is an approved CE organization and service codes for collaborative projects have been created in BI for use by FMN volunteers as projects develop.

Habitat creation and restoration – E405: Educational Projects Fairfax Tree Stewards – – FTS
Educational project code for Fairfax Tree Stewards (FTS).
Educational Projects could be advising a homeowner or association on proper tree selection and planting, education about maintenance, developing resource lists, or FTS tabling events at selected locations in Fairfax County.
When recording these hours in BI, ‘FTS’ should be entered as the Project Organization.

Habitat creation and restoration – S405: Stewardship Projects Fairfax Tree Stewards – – Department of Forestry (VDoF)
Stewardship project code for Fairfax Tree Stewards (FTS).
Stewardship Projects could be helping a homeowner or association with proper physical design, planting, tree pruning, or maintenance, at selected locations in Fairfax County.
When recording these hours in BI, ‘Department of Forestry (VDoF)’ should be entered as the Project Organization.

To participate in FTS projects, one must be a certified Fairfax Tree Steward along with being an FMN member.

UPDATE- new training location: The National Park Service (NPS) Needs Volunteers to Help Save the GWM Parkway’s Trees, January 21st

Photo: FMN J. Quinn

Saturday, January 21, 2023

New Location: Fort Hunt Park
8999 Fort Hunt Rd,
Alexandria, VA 22308


To Attend the training please register here.

The National Park Service (NPS) needs volunteers to help remove English ivy from many trees along the south GW Memorial Parkway.

Mireya Stirzaker, NPS Natural Resources Specialist, will hold a volunteer training on January 21 at 10 a.m. at NPS’s Collingwood Park/Picnic Area on the east side of the parkway.

What’s Involved

Mireya will help people learn how to remove ivy, designate safe areas in which to work and supervise at least one session.  NPS can provide some tools and supplies.

To attend the training, register at  On January 21, dress warmly in layers, wear sturdy shoes and bring water. You can volunteer once or multiple times.

Ivy’s Harm

Invasive English ivy is a perennial, aggressive plant that covers the ground, crowds out valuable native plants and climbs up trees.

It can smother a tree’s bark and block the sunlight needed for photosynthesis.

Trees weighed down with ivy vines are more susceptible to toppling during rain, snow and ice storms.

Around 20 percent of the parkway’s plants are not native, according to NPS biologists. Most invasive, introduced from other areas accidentally and deliberately have few controls, form monocultures, impair biodiversity and destroy native habitats.

Why Care about the Parkway’s Trees

Trees sequester carbon, reduce other pollution, stem stormwater runoff, reduce cooling costs and provide habitat for birds and other wildlife.

The parkway is losing trees because of, for example, the invasive emerald ash borer.  The Dyke Marsh Wildlife Preserve alone could lose around 1,000 ash trees.

Many oaks are suffering too.  Over-abundant deer eat young saplings which alters forest succession, prevents regeneration of plants and impairs biodiversity.

A Memorial Parkway

In 1928, Congress authorized the construction of the Mount Vernon Memorial Parkway to honor the bicentennial of George Washington’s birth.  Planners created a design that includes forested areas, minimizes signs and lights and prohibits billboards.  It is intentionally a slow-speed parkway and trail of natural, historic and recreational sites in over 7,000 acres of parkland, our national park.

Healthy, native trees are an integral part of that design and consistent with Congress’s intent.

Photo: FMN Ana Ka’ahanui

Thursday, February 2, 2023
7 – 8:30 pm
$10 ASNV members/$15 Nonmembers

Register here.

Join Greg Butcher, Audubon Society of Northern Virginia board member and recently retired migratory species coordinator for the U.S. Forest Service International Programs, for an introduction to waterfowl identification. Get to know many of the species that winter in the open waters of our region. You’ll learn how to tell a Bufflehead from a Hooded Merganser, and, you’ll learn the features (and hear the call) of the beautiful Tundra Swans that winter in Northern Virginia. Strategies will include identification by shape and color pattern. After the presentation, test your identification skills with a Kahoot!

This event will be helpful for those participating in the Winter Waterfowl Count on Feb 11-12 but is open to anyone who would like to know how to identify winter waterfowl!

There is an optional field trip for a limited number of participants, but you are encouraged to do your own independent field trips to see winter waterfowl! Some good locations to see waterfowl in NoVa are Huntley Meadows, Dyke Marsh and Mason Neck State Park.
