Fall Cleanup in Two Easy Steps

Here is an executive summary of eco-friendly yard maintenance recommendations for fall.

  1. Watch the pretty leaves flutter down from above.
  2. Do as little as possible to disturb those leaves or the flower stalks.

In the days when gardening meant growing food for the table, cleaning out plant debris before winter was a routine practice to reduce the spread of diseases that affect vegetables. That routine carried over when suburbanites switched their yards to ornamental plants and turf grass, with the unfortunate consequence that we deprived our non-human neighbors of the shelter and food they need to survive. The tide is turning, though, as people are realizing that attractive gardens that support the ecosystem do better when their caretakers go easy on the autumn chores.

Some birds and nocturnal mammals are able to dig for grubs in a lawn, but you may have noticed that most friendly critters such as box turtles, frogs, and katydids do not spend a lot of time frolicking on your turf grass. It would leave them much too exposed, not to mention starving. Layers of leaves from native trees and shrubs, by contrast, provide a smorgasbord for them. Some of their meals consist of the caterpillars and other insects that feed on the leaves of native trees in spring and summer until they float down to the ground in the fall. Those that escape predation turn into adults the next spring and start the cycle over. Other insects such as fireflies spend their entire lives in the leaf litter, coming out briefly to find mates. All this assumes that their homes are not chopped up or raked up to be sent off to mulch factories.

Similarly, dead stalks provide shelter for many little critters, including certain species of native bees that burrow into the ends of broken stalks to lay their eggs.  Plants left intact enliven our yards all winter with their interesting seed heads and waving stems, made even more lively as the songbirds perch on the stalks and scrabble in the leaves for the seeds of flowers and grasses.

As the plants emerge again in the spring, they have no trouble pushing past the dead leaves, which act as a natural mulch until they gradually decompose and feed the soil. Many of the dead flower stalks will have fallen down by spring, and those remaining are quickly hidden from sight by the growing plants. If those plants are native to our ecosystem, they continue to provide benefits the rest of the year by nourishing the caterpillars and providing nectar and pollen for the pollinators. Some of the thicker leaves such as oaks may smother turf grass under the trees, but that is just as well, since mowing around trees risks injuries to their bark, and walking under them compacts the soil and stresses the roots. Trees do best when their leaves are left in place out to the drip line. But if that isn’t possible, try to move these leaves intact into other beds.  Mulching fallen leaves with the mower blade is better than sending them off in a truck or dumping smothering piles in the woods, but it may chop up the insect larvae and eggs.

Simple adjustments such as these to our landscaping practices will greatly improve the prospects of our local ecosystem. Other important steps to take include adding native plants, removing invasive non-native plants, minimizing the use of outdoor lighting, and eliminating mosquito spraying with its lethal consequences to the living world.

Despite Predation, Bluebirds at Langley Fork Park Endure

As Bluebird Trail Monitoring Leader at Langley Fork Park in McLean, I have been trying to optimize the environment for the bluebirds at the park. The trail monitoring team and former trail leader all help in the effort, so I am fortunate to have their assistance.  

In 2021 we nurtured 63 total protected birds which included 26 bluebirds.  In 2022 we had 57 total protected birds which included 24 bluebirds.  In 2023 we had 49 protected birds of which 14 were bluebirds.  This can be contrasted to the five years prior to that in which Langley Fork Park monitoring succeeded with about 40 protected birds per year which included about five bluebirds a year.  Our efforts in the recent past are successful compared to the longer historical record. 

Were it not for the loss of 14 bluebird eggs in 2023, the count could have been 28 bluebird fledglings.  That would have been larger than the 2021/2022 counts.  All but one of the bluebird eggs were loss to predation.  On the other hand, all but one of the seven unhatched tree swallow eggs were part of clutch sizes that also included fledglings.  The solitary tree swallow egg in a Box 11 attempt was overcome by an ant infestation.  Another year of snakes at Box 7 resulted in five tree swallow nestlings being devoured. Consequently Box 7 has been moved, as was Box 9, that had four bluebird eggs vanish.  Indeed Box 7 was also attacked by a snake last year.  There aren’t any overhead trees in the area, and we maintained the grass so no large weeds could provide a pathway for snakes.  Nonetheless, it seems snakes can be skillful predators traveling up the bluebird pole and baffle.

As for a solution at the end of the season, we paired Box 7 with Box 4, as pairing boxes can provide

Box Pairing Experiment at Langley Fork Park. Boxes 5 and 9 in the photograph are spaced approximately 10 feet apart, as are Boxes 4 and 7.

positive outcomes when good park locations for boxes spaced more than 100 yards apart are limited.  This solution was used for Box 9 too, as it seems the birds didn’t care for all the playing field activity around Box 9’s former location.  Box 9 is now paired with Box 5.  This will be an interesting experiment. 

Bluebirds are territorial, so two pairs generally won’t nest in boxes that are closer than 100 yards. Though, boxes in pairs might attract a different species, like tree swallows.  Tree swallows compete with other species such as bluebirds, as well as their own species.  Tree swallow pairs will compete, sometimes to their deaths, with each other for nest sites.  Male tree swallows will claim a bird box and guard it, in hopes of attracting a female tree swallow.  Consequently there is a strange dynamic ensuing.  By installing boxes in pairs, they will be close enough that both boxes are unlikely to be occupied by the same species, but just plentiful enough to allow for another species without an aggressive competition between the two species.  This strategy has worked on bluebird trails.  There are different recommendations on how far apart to place the pairs, from on the same pole to as much as 24 feet apart. We placed our two pairs at about 10 feet.

Status of 2022 Changes

The start of the 2023 monitoring season incorporated some changes recommended in 2022.  Our team agreed that moving Boxes 1, 4, 7, 9 might help the bluebirds.  The data showed that Boxes 1, 2, 5, and 9 never had bluebirds. We also had the opportunity to add an 11th bluebird box which was installed.   

  • Box 1 was moved closer to the parking lot to get more attention by the bluebirds.  As a result of the move, the box produced 3 bluebird and 5 tree swallow fledglings. 
  • Box 4 has had occasions of broken eggs from intense competition.  Moving it from the corner of the field to a more bushy area closer to some benches improved it.  In 2023 this box produced 5 tree swallow fledglings.
  • Box 7 had a snake predator in 2022, but it was not under any trees and the weeds around it were cut.  We decided to leave it in place at the last moment in 2022.  Unfortunately in 2023 it was once again attacked by snakes.  No fledglings survived.  To avoid that mistake again, Box 7 is now paired in a good location for the upcoming 2024 season. 
  • Box 9 was moved a few yards farther from the human activity at this playing field area. Yet in in 2023 this box did not produce any fledglings and four bluebird eggs went missing. It is now paired in a better location for the upcoming 2024 season. 

Finally, something should be said of unhatched eggs, which for the most part is uncontrollable. Unhatched eggs could be a result of issues related to temperature, humidity, infertility, environmental chemical use, or physical damage to the eggshells. Sometimes too, if the female bird is inexperienced, or if there is not enough food nearby and she has to leave the nest frequently to forage, the eggs can be affected  negatively.

Science in Your Watershed

A watershed is a common geographic area that drains all streams and rivers into a common outlet, like a bay.  The Northern Virginia Soil and Water Conservation District has a macroinvertebrate stream monitoring program that helps protect our watersheds:

https://www.fairfaxcounty.gov/soil-water-conservation/volunteer-stream-monitoring

Getting to know your watershed is like getting to know your neighborhood.  Our local Potomac Watershed is part of the Chesapeake Watershed, which is part of the Mid-Atlantic Watershed, and which is part of the Eastern Watershed.  A principal river of a basin is a river that drains directly into the ocean.  Our Atlantic Seaboard Basin includes the Hudson River, Delaware River, Susquehanna River, our local Potomac River, and the Savannah River.  Your watershed’s information can be found at this USGS website which contains many USGS links:

https://water.usgs.gov/wsc/map_index.html

You can visit the Environmental Protection Agency (EPA) website, type in your zip code, and get a local map of your watershed: https://www.epa.gov/waterdata/hows-my-waterway.  For example, my Reston home location is part of the local Difficult Run watershed.

Illustration by author:  Local Watershed Generated by the EPA website per input of the 20191 zip code. Notice the drainage pattern. Depending on a location’s geology, drainage patterns can be dendritic, trellis-like, rectangular, or radial.

The website provides physical, chemical and biological water quality factors from its monitoring locations.  In Fairfax County, drinking water comes from two major sources: the Occoquan Reservoir and Potomac River.  Fairfax Water operates both the Corbalis and Griffith treatment plants, where water undergoes a series of treatments.  In recent years, new emerging contaminants have become a concern in drinking water. You can help protect the drinking water quality in Fairfax County by preventing water pollution and reducing runoff.  For example, don’t flush expired pharmaceuticals in the toilet, and keep car wash suds out of the storm drains.

By visiting the USGS water data website, more interesting data can be gleaned: https://waterdata.usgs.gov. I used this site to compare historical information to an unusually high level of water in the Potomac River following a large rain event.  The unusual event took place on June 2, 2018, the day I took a geological excursion to Great Falls Park with Northern Virginia Community College (NVCC).

The flux of the Potomac River on June 2, 2018 was 25,000 cubic feet per second as recorded at Little Falls dam and pumping station. River flux is controlled both by precipitation and the size of the watershed. Flux affects erosion rates. When a path of a river narrows the velocity rises, and there is more erosion by 3 types of stream loads. Dissolved load is comprised of invisible minerals carried to the ocean, where through evaporation and concentration, the ocean receives its high salt content. The suspended load carries the coarser sands and requires a faster velocity.  The competence of a river is the maximum particle size that it can transport, and the thalweg is the line of lowest elevation within a watercourse. As one walks toward a thalweg, the brushing of sand particles upon the leg will be stronger. The bed load rolls along a river bottom, and these carry the largest and heaviest materials. The Appalachian Mountains feed these three loads through erosion.

The mountains now average about 3,500 feet in height, but were up to 20,000 feet at peak height some 200-300+ million years (Myr) ago. These higher mountains had a steeper gradient 100 Myr ago. The velocity was higher, as well as cut down, and so too the erosion. As a river cuts down, mass wasting can fill in through rock falls on the sides. In 100 Myr the Potomac River will be flatter and wider with a lower gradient. This is compounded by rising sea levels by melting polar region ice.  During the entire time of our NVCC geologic hike through Great Falls Park we did not change elevation.  But there was a cut down from upstream (where we stood on the shoreline) to downstream of the river (where it was a gorge). Another type of river dynamic is headward erosion. Downstream waterfalls push rocks off causing the waterfall to slowly move upstream. In floods the competency goes down and larger particles settle as the river covers a wider area.

The Corporate World Embraces Native Plants

/in , /by

Most corporate properties have pretty “standard” landscaping, meaning the plants do very little if anything to support the local ecosystem. More and more, though, we are seeing innovative landscape designs on commercial properties that demonstrate the potential for corporations to be leaders in the effort to save the natural world, starting on their own land. While they are at it, they are creating beautiful and welcoming spaces for their clients and employees.

One example of this approach is the work done at the recently-opened Kaiser Permanente medical centers in Springfield and Woodbridge (Caton Hill). Both properties are richly landscaped with trees, shrubs, grasses and perennials that are almost entirely native to Northern Virginia. (The few exceptions are non-invasive.)

According to Alton Millwood, director of Planning, Design and Construction at Kaiser Permanente Mid-Atlantic, “The landscape design at Caton Hill Medical Center focused on allowing the natural environment to be a part of the community’s wellness plan. There is an abundance of research showing that exposure to nature can lower our heart rate, alleviate mental distress, speed recovery rates, and even alleviate symptoms of mental disorders. This is why Kaiser Permanente felt it was important to keep natural woodland areas on the project site and invite people into those space with trails and areas to sit and relax. Additionally, the native plants used on the site help to create a healthier environment by providing food and habitat for birds and other wildlife, conserving water, and reducing noise and pollution associated with mowing. It only made sense that if we were going to involve the natural environment for our own health that we would do what we could to improve the health of the environment.”

Another goal of the project was to help Northern Virginia region meet its stormwater goals to protect the local streams and the Chesapeake Bay. The planting beds and the rooftop meadow decrease the amount of runoff from impervious surfaces. Design considerations included using a variety of native plant species to provide four-season interest, using low-maintenance plants that will not require long-term watering, and choosing species that will grow to the appropriate size for their locations so that important sight lines remain open and safe.

The reaction of employees and patients alike has been extremely positive. “Many members and staff have taken advantage of the outside seating, walked through the Gardens and Health Park to immerse themselves in nature and its healing benefits, and observed the rooftop meadow flowers in full bloom, with birds and pollinators busy in their tasks.”

Asked what would be his advice to other corporations, Alton replied, “Using sustainable design practices such as planting native plants is good for people and the environment – it is a win-win. For corporations, sustainable design can impact their bottom line, too. Native plants are more likely to live long and thrive in our environment. They require less maintenance, less fertilizer and pesticides, and less water. All this adds up to savings for the owner. Hiring a like-minded design professionals can help you create places like Caton Hill Medical Center that help benefit our community and the local ecosystem.”

Advantages of Natural Science Sketching

Article and illustrations by FMN Stephen Tzikas

We all have a bit of an artist in us when we learned to draw and use coloring books as children.  Some of us went further. I started self-learning art with the Jon Gnagy sets from the 1960s and 1970s.  He also had a television show.  My first dedicated art class was in 9th grade.  Among master naturalists, there are many sketchers, and I will offer my perspective on this subject.

My first application of art was with the Association of Lunar and Planetary Observer (ALPO).  They have a 1 year observing program focused on sketching astronomical objects.  What made the ALPO observation program so unique was an appreciation for details one cannot “casually see” or photograph.  When I first started this program, I was asked to pick a lunar crater and draw it as observed through a telescope.  My first sketch was not much more than a 1 minute drawing with a circle and a shadow in it.  By the time I graduated that program, I was sketching similar craters that would take me 3 hours to complete because of all the detail I could now see for which I was oblivious when I started the program. To illustrate this, I provide an example of my sketch of the crater Arzachel on the Moon.

Sketch of Moon Crater Arzachel, August 4, 2014 at Colongitude 7.97 degrees.  Magnification 169x using a Meade 12” Lightbridge telescope in Reston, VA.

Sketching details incorporate a gray tone scale (1 through 10) using different labelled pencils for this purpose. Moreover, a photograph can’t capture all the differences in live perception. Especially in astronomy, viewing gets distorted by the atmosphere. A properly identified astronomical sketch includes criteria to understand its context, such as the time and date, the object, the telescope used, and the accessories.  These sketches are accepted by various organizations as a record for future generations.   

Numerous natural science genres include colored scientific illustration, comics, and journals. Art I have seen over the decades show how illustrations have evolved, sometimes forced by necessity.  I once sketched a full Moon to compare my attempt to Galileo’s first attempt.  By then I was trained in astronomical sketching.  This feat is impossible to do in a night because many more hours would be needed than available, and keeping in mind that the shadows on the Moon are constantly changing due to movement through space.  This shadowing is defined by co-longitude and is the reason why one cannot just continue a lunar sketch the upcoming evening.  Out of necessity a style needs to be created to capture a background in a sketch and these styles evolved with time.  Style (what to accentuate) is not only a function of the historic time it was created, but also social factors that may have included materials available, social beliefs, talent, interpretations, and imagination.  The historically preserved sketch is a record of what could have existed at a time but no longer does.  Historical sketches and paintings often include environmental conditions useful to scientists, even if those works were never intended for that purpose.    

In a wider context, art can be a record of human consciousness.  The human consciousness can incorporate aspects of psychology, anthropology, and philosophy. Indeed, art can use a broad brush, to borrow a metaphor.  Art has its own unique place in nature sketching.  I would encourage others to submit articles to the FMN Newsletter as a means of preserving the various forms of art and observations for future generations. 

In addition to the FMN Newsletter as a source for art-related information, there is the art competition for the FMN recertification pins. Also, there are nature journaling meet-ups at the Clifton Institute and nature art classes are given at Hidden Oaks Nature Center.  Always available are You-tube videos on sketching. Just have a look at the fine pieces of art posted on the NOVA Nature Journal Club Facebook group at: https://www.facebook.com/groups/544583139673338

John Muir Laws also provides free videos online that have helped people become skilled observers to creatively document their experiences with nature. Experiencing the moment can sometimes be quite different from what a static photograph portrays. See the website at: https://johnmuirlaws.com/

Tree-of-Heaven is Not Heavenly!

/in , /by

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!

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!
