The pollinator garden redux at the Potomac River Occoquan National Wildlife Refuge is certainly not a complete success story yet but the story behind how it got started and kicked off is a complement to success.

Let’s rewind … FMN set up an outreach table the Mason Neck Eagle Festival a few months ago. Near day’s end Gabby Youngken, Visitor Services Specialist at Potomac River NWRC, stopped by to see if FMN could advise them on how to refurbish their on-site pollinator garden. As circumstances would have it Sarah Mayhew had recently established an FMN Chapter Project (CP179) at Mason Neck to do their gardens. With FMN Steph Johnson as technical advisor, Sarah and other FMN members, along with Friends of Mason Neck, developed a phased work and maintenance plan/schedule and were in the midst of working it.

Fast forward … Because everything was documented the Mason Neck plan was easily extensible to NRWC. Surely since NWRC is directly across Belmont Bay from MNSP it stands to reason they would have the same weeds. Right? FMN sent MNSP plans to NWRC for review; followed up with a site visit to NRWC; met the staff; toured the property; and then tailored the plan for them. We then had to gather a volunteer base to execute the plan. FMN contacted Merrimac Chapter, since they operate in Prince William county. FMN has a frequent volunteer in the NWRC visitor center – he was in. Master Gardeners was interested in helping. NWRC has a few volunteer groups they tap and of course several hard working interns from the American

Conservation Experience, EPIC Program. With the team set, Gabby picked 8 Aug to kickoff the project. Many hands make short work! Phase one done!

The team was able to save several native plants for reuse, turn the soil to remove roots, and then cover with black plastic (to smother roots) until the scheduled fall planting.

So the ‘success’ to date is really credit to how the group came together as a result of outreach to cooperate and collaborate on a project that benefits our park systems. Stay tuned for more on this effort when it completes.

Bonus factoid: The Potomac River National Wildlife Refuge Complex is a complex of three National Wildlife Refuges in Virginia located along the Potomac River.
The three refuges are:
* Elizabeth Hartwell Mason Neck National Wildlife Refuge
* Featherstone National Wildlife Refuge
* Occoquan Bay National Wildlife Refuge
The first two are administered jointly for planning, while the third is currently treated separately.
The pollinator garden is at the Occoquan Bay site.

Tree-of-Heaven is Not Heavenly!

Article by Cindy Speas, Chair, Fairfax County Tree Commission

In summer many folks travel to the Shenandoah Valley and beyond for recreational opportunities. Driving in any direction from Northern Virginia in the growing season, there is a tree that can be seen everywhere along the highways and byways. The dramatic clusters of seeds are so large they look like giant flowers among the leaves. It’s not native walnut or native sumac—it is Ailanthus altissima, commonly called Tree-of-Heaven. Disturbed areas and right of ways along roads are perfect locations for this opportunistic pest to colonize. Ailanthus is popping up in suburbia as well, and those of us who love trees wonder why experts are calling for us to remove these attractive and fast-growing specimens from our properties as soon as possible?

Ailanthus was imported from China and widely distributed in the United States as an ornamental in the late 1700s and 1800s. Its behavior, though, is far from heavenly—it spreads aggressively through root sprouting and huge seed production; it grows to maturity rapidly with a very long taproot; it is characterized by its terrible odor; and it poisons the ground around its roots with chemicals, in a process called allelopathy. This prevents native trees and plants from growing nearby, allowing Ailanthus to quickly spread and dominate our landscape.

Additionally, Ailanthus is the preferred food source for a new invasive insect—the Spotted Lanternfly (SLF). In spite of state quarantines, this destructive pest has now been found in Fairfax County. It is a major threat to some of Virginia’s agricultural areas, especially our vineyards, peach orchards and hops. It is also a threat to native tree species like oaks and maples that thrive in our yards. Forest Pest Branch asks all residents to report Ailanthus here and report Spotted Lanternfly sightings here.

Some may ask why these non-native trees should be removed—don’t they at least provide shade and shelter in a warming world? They certainly can, but they crowd out our native oaks, beeches, hickories and maples, as well as failing to provide the critical food resources that native insects and other animals need to live and reproduce in a fully functioning, healthy ecosystem. If a plant like this is killing off or threatening major parts of our local natural food web, the entire system will eventually collapse. And we will lose our native tree canopy along the way.

How can we stop the spread of this nasty invasive? The first thing, of course, is not to purchase it in the first place! So be sure to learn how to identify it. You can become familiar with the iNaturalist app on your smartphone or use other online resources to name the plant. The second is to remove the tree if it is growing on your land. This pest, however, thrives when simply cut down, so strategies must be used to kill the root system right away. There are some excellent resources to help landowners eliminate this threat safely and efficiently. Blue Ridge Prism has excellent fact sheets with details about herbicide use for this and other invasive species.

Visit Plant Nova Natives for more information about invasives and their destructive roles in our native environment. If we could eliminate a threat like the Tree-of-Heaven, that would truly be heavenly.

Box Turtles Surveyed at The Clifton Institute

In mid-May I joined a group of citizen scientists  gathered at The Clifton Institute (Clifton) in Warrenton, Virginia, equipped with a radio receiver and antenna.  As the faint pings from the receiver grew louder, we followed the direction of the strongest sounds and eventually found our prize, a Woodland Box Turtle (terrapene carolina carolina)!  The transmitter equipped creature was snuggled in tall grass and would have been difficult to find without the transmitter.

We began our day learning about Clifton’s ongoing Box Turtle research program from Andrew Eberly, Habitat Specialist and our guide for the day.  Clifton is unusual in being not just an education center but also a research station and a conservation organization. That means that participants on their field trips have the unique opportunity to participate in real scientific research and to see ongoing restoration projects in action.

In spring 2022 Clifton launched an exciting new research project on Box Turtles. The goals of the project are to better understand how Box Turtles are doing at Clifton (where they are still common), why they are declining in the region, and how landowners can help turtles. They are especially interested in studying the animals’ movements in different kinds of habitats so that they can advise landowners on when and how to change mowing and haying practices to minimize turtle mortality.

When they find a turtle they notch its shell with a unique code so that they can identify it when they (hopefully) see it again. They have found more than 106 turtles! They estimate that roughly 370 turtles live on the 400 acres they have surveyed. They have been amazed to find so many and want to figure out what makes their property so turtle-friendly.

As a pilot study, they attached radio transmitters to five of the turtles and tracked their movements to get a better idea of where they’re hanging out and when. Five turtles didn’t tell them much, but the tracking worked well enough that they had expanded to twenty turtles by the time of the May field trip.

After some of us took turns using the receiver and antennae to locate some of the previously

identified turtles, we moved to “Turtle Junction”, a site on the property known for its turtle habitat.  We were delighted to find two more unmarked turtles there.  Andrew carefully notched their shells, and weighed and measured them to log them into the survey subjects.

Flush with success, the group moved out of the lush forested area just as a spring downpour began.  Although The Clifton Institute is a 45-minute drive away from my home, the trip provided enough education, outdoor time in beautiful surroundings, and the feeling that I had added needed information to citizen science that I would readily go again and highly encourage you to do the same!

Results of The Clifton Institute’s 28th Annual Butterfly Count

/in , , /by

Photo by Juan Gonzalez, Peck’s Skipper at The Clifton Institute 28th Annual Butterfly count

The Clifton Institute had a great count this year! They found 1,856 butterflies of 39 species. Compared to previous years, numbers were down, but diversity was about average. Other butterfly counts in the area have been down this year as well and we are guessing that the drought is to blame. Despite that, they had new high counts for Pipevine Swallowtail, Pearl Crescent, Red Admiral, Horace’s Duskywing, and Sachem, and no new lows. Numbers of Sachems and Pearl Crescents were both way up from previous highs.

Photos from the day are here!

This year they had the help of 38 volunteer counters that ranged from beginners to experts. Their area leaders were David Cox, Victoria Fortuna, Sue Garvin, David Gorsline, Walt Gould, Larry Meade, and Rebeca Sanchez-Burr. Many thanks to all for supporting the count!

A Thank you also to all of the landowners that allow access and make this count possible each year! Peck’s Skipper photo by Juan Gonzalez.

Report Your Plantings: Every Tree Counts!

/in , , /by

From Plant NOVA Trees:

Every tree counts! And counting every tree also helps show whether Northern Virginia is meeting its environmental goals. The Virginia Department of Forestry is counting planted trees to see if Virginia is meeting its stormwater goals to protect the bay, and the Department of Environmental Quality is asking Northern Virginia to plant 600,000 trees by 2025.

​Birch leaf_edited.png                  Birch leaf_edited.png

Since most available land in Northern Virginia is private property, this goal will not be met without planting thousands of new trees in our own neighborhoods. Help keep track of the progress and build momentum by reporting your tree planting. The tree planting reports are forwarded and added to the Virginia Department of Forestry’s My Trees Count map, which is updated a couple times a year.

​As of 7/20/2023:  12,677 trees and shrubs reported!

FMN Chapter Project Update by Sarah Mayhew

The pollinator gardens at Mason Neck State Park remain a work in progress.  Some of them are looking beautiful and others are still looking neglected.  That is because we are responsible for reclaiming 6 different pollinator garden beds.  Five of them are looking good.  The sixth one is the largest — the Woodland Edge Garden is 56 ft x 52 ft or almost 3000 sq. ft.  Our two July workdays focused on getting 1/3 of the Woodland Edge Garden cleared for “smothering” the Japanese Honeysuckle under black plastic.  Here are the before, during, and after pictures of that work:

As you can see, there was a lot growing and then we cut it all down to ground level.  The next workday our volunteers laid down the black plastic, creatively repurposing the chicken wire we removed from the fence to help weigh down the plastic!

Our August workdays will be on Tuesday, August 8, and Saturday, August 12, 2023.  We have moved the start time to 9:00 a.m. to avoid the heat.  Our goal for these two days is to remove a large multiflora rose bush and selectively weed some invasives from the remaining two thirds of the garden that is in much better shape.  We will be identifying many native plants as we go, so you will have a good opportunity to learn new plants, too.  You can sign up to help us here:  Mason Neck State Park Pollinator Garden

 

There is one more update to the Chapter Project schedule.  We discovered in July that our “second Saturday” schedule conflicts with the Green Breakfasts.  We are moving our workdays to a “third Saturday and third Tuesday” schedule beginning in September.  We don’t want to deprive any member of the Continuing Education opportunity the Green Breakfasts provide.  Keep learning!
