Leave Fawns Alone!

Article and photos by Virginia Department of Wildlife Resources

It’s that time of year again when white-tailed deer fawns are showing up in yards and hayfields, and concerned citizens want to know how to help. In almost all cases, the best way to help is to simply give the fawn space and leave it alone.

Concerned people sometimes pick up animals that they think are orphaned. Most such “orphans” that good-intentioned citizens “rescue” every spring should have been left alone. Most wild animals will not abandon their young, but they do leave them alone for long periods of time.

Fawns, born from May through July, are purposely left alone by their mothers. Female deer, called does, stay away from the fawns to avoid leading predators to their location. The white-spotted coat camouflages a fawn as it lies motionless in vegetation. Young fawns generally will not try to run away when they are approached.

Does will return several times each day to move and/or feed their young. You probably will not see the doe at all since she only stays to feed the fawn for just a few minutes before leaving it alone again. If less than 24 hours have passed since a fawn has been “rescued,” the fawn should be taken back and released at the exact same location where it was found. After returning the fawn, immediately leave the area and do not wait for the doe to return. The doe will not come back for the fawn if a human is nearby.

Help Keep Wildlife Wild

If a wild animal has been injured or truly orphaned, do not take matters into your own hands. You may locate a licensed wildlife rehabilitator by calling the Virginia Department of Wildlife Resources (DWR) toll-free wildlife conflict helpline at 1-855-571-9003, 8:00AM-4:30PM, Monday through Friday or visit the Licensed Wildlife Rehabilitator section of the DWR website.

Raising a wild animal in captivity is illegal unless you have a DWR wildlife rehabilitation permit. Each animal’s nutritional, housing, and handling requirements are very specific and must be met if they have any chance of survival. With even the best professional care possible, the survival rate of rehabilitated fawns and many other animals is very low. The best advice for someone who wants to help wildlife is to keep it wild. Once people interfere, we reduce the opportunity for animals to receive natural care and we increase the risk of harming our wildlife heritage.

Humans and Trees Share a Common Enemy: Stress!

Article by Elaine Kolish; feature photo: Plant NOVA Natives

We all know that chronic stress affects our health and well-being, causing us to go into “fight or flight” mode. That, in turn, can lead to a variety of health effects ranging from depression to high blood pressure, which itself can increase our risk for stroke or heart attack. Ongoing stress also affects the health of trees. But unlike us, they have limited options for reducing their stress. They can use internally produced chemicals and scents to deter predators and warn other trees of threats, as well as help stressed neighbors by sharing water and nutrients through an underground fungal network. But they can’t pick up and move to avoid stressful conditions. We need to step in and alleviate tree stressors to the extent we can, particularly those caused by human activity. The good news is that caring for trees and spending time in nature can reduce our own stress. A win-win.
Although there are some stressors – such as early spring frosts, extreme heat, and heavy snow and ice – where we are mostly powerless to help, there are many others where we can make a difference. And it is important to do so, because trees can die from exposure to long-term stress, such multi-year droughts.or become more susceptible to insect pests or to diseases that kill them. Let’s look at some human-caused stressors – ones that we can control – and at environmental tree stressors such as drought, where we might be able to help.

·         Use the right plant in the right spot. Right off the bat, you will stress a tree if you plant it in the wrong spot. For example, a shade loving, understory tree such as Flowering Dogwood is going to be highly stressed if planted in full sun in dry soil. Consult plantnovatrees.org for help in choosing the right trees for your site.

·         Use proper planting and staking techniques, These include not planting the tree too deeply and not burying the trunk flare. Think about whether you need stakes and guy wires, because preventing a tree from swaying in the wind will weaken it. If you do use them, always remove them in a timely fashion and not later than a year after planting. When left on too long, stakes can girdle and kill a tree. For information on how to plant a tree properly, consult Fairfax CountyTree Basics.

·         Use proper mulching techniques. Mulch should be applied in a donut shape, not a volcano, and should not touch the tree. When piled high against the tree, mulch can cause decay and ultimately death. The mulch should not be more than two or three inches deep to allow the rain to penetrate. If for some reason you want to add more every year, you should remove the old mulch first.

·         Avoid competition for water. Trees and turf are not friends. Since both have shallow roots, they compete for water and nutrients, and turf wins the battle in the tree’s early life. Also, if there is grass under trees, we run the risk when mowing of damaging the bark, nicking shallow tree roots, or compacting the soil. Any of those will stress our trees. Mulch and/or dead leaves under trees is best, and the larger the ring, the better. A large turf-free ring also provides the opportunity for underplanting with native shrubs and ground-layer plants, creating a mini productive habitat for insects and wildlife.

·         Everyday activities that can hurt trees. Chaining bikes or other items to trees can damage their bark, as does allowing car doors or bumpers to hit them. Repeatedly wounding their bark makes trees vulnerable to decay and disease. Parking under trees also causes soil compaction that can suffocate tree roots.

·         Use proper pruning methods. Don’t top trees! That is a sure way to weaken a tree, make it structurally less sound, and in the most extreme situations eventually kill it. It is useful [1] to take out broken, diseased and dead branches. For example, a clean cut to remove a broken branch helps a tree recover from a wound better, and pruning out a dead branch keeps it from falling unexpectedly and damaging something or someone.  If you don’t know how to prune trees properly, hire a certified arborist to do so or consult one of the many how-to-prune books you can find at the library. A good reference book can show you how to prune trees so they are free from structural weakness and are as healthy and vigorous as possible.

·         Water during droughts. We may not think to water our native trees and shrubs, because a key characteristic of native plants is that once they are established, they no longer need to be watered. But, when there is a drought, even natives may need to be watered, and that is especially true if they have limited soil space from which to draw water, such as in a small tree box next to a street. Without sufficient water, trees will lose their fine absorbing roots and leaves and move to a dormant state. Years of drought and/or other stressors eventually can cause the tree to die.

·         Protect young trees from deer browse. Unfortunately, an overabundance of deer can stress and threaten the survival of our woodies. Consult Plant NOVA Natives for strategies to deal with that.

Although human actions as well as environmental factors can stress trees, we can avoid causing harm and can take actions that keep trees healthy and vigorous. Trees provide us so many benefits, including a profound sense of well-being, that it is well worth it for all of us to do all we can to reduce tree stresses and promote tree health.

New Particulate Pollution Air Quality Index

You may soon notice some changes to the Air Quality Index (AQI). The AQI is a standardized color-coded scale used to describe health concerns associated with common pollutants such as ground-level ozone and PM2.5 (particulate pollution smaller than 2.5 microns in diameter). The AQI can range from 0 to 500. An AQI from 0-50 is green, for good air quality, whereas an AQI above 300 is maroon, meaning that air quality is hazardous. When the AQI is above 100 (orange or worse), air quality is unhealthy: first for sensitive groups of people, then for everyone as the values increase.

On May 6, the AQI changed for PM2.5 such that the breakpoint between green (good) and yellow (moderate) air quality has become more stringent. The Moderate category now begins when fine particle pollution concentrations reach 9 micrograms per cubic meter of air (the level of the updated annual air quality standard). Previously, the Moderate category began at 12 micrograms per cubic meter. EPA implemented this change to increase public health protection, consistent with evolving scientific understanding of the impacts of PM2.5 pollution. As a result of this, you may see air quality reach the yellow (moderate) AQI more frequently than in the past.

Create a Mini Meadow

Article and photo by Plant NOVA Natives

When they aren’t being bulldozed over, the natural state of most meadows in Northern Virginia is to gradually revert to forest, but that fact does not lessen their importance to the ecosystem. Although there are many threats to our woods, it is the meadows that are disappearing the fastest, which is a big problem for birds and other critters that depend on sizable meadows for habitat. When was the last time you saw a meadowlark or a quail, for example?  So if you own land with a natural meadow, you do a great service by preventing it from reforesting (or from being developed.)  

Most of us don’t have natural meadows on our properties, but we, too, can help repair some of the damage by adding meadow plant species to our yards. In most cases, that translates to creating pollinator gardens that can serve as mini-meadows or small-scale meadow analogs that attract hummingbirds, butterflies, and other pollinating insects. Even relatively small spaces can foster meadow habitats, especially because much of the ecological value of a meadow comes from common, easy to find, easy to grow species.
Start with just two or three sturdy and meadow-loving natives that produce beautiful flowers and attract pollinators as well, such as Butterfly weed (Asclepias tuberosa), Goldenrod (e.g., Solidago rugosa or Solidago caesia), Mountain mint (e.g., Pycnanthemum tenuifolium), and Hollow Joe-pye-weed (Eutrochium fistulosum). Plants like to grow in communities near other plants. It’s a good idea to put three to five of them together, which mimics the way plants grow naturally in meadows. You can always increase the types and number of native flowering plants in your mini meadow, expanding it over time as your space and interest allows.
Pollinator turnout on flowering natives is high. Dozens if not hundreds of hummingbirds, bumblebees, flies, beetles, and hummingbird moths, along with many other kinds of pollinators, will show up. The more varied your mini meadow offerings, the more diverse the pollinator population it will attract. It is sure to delight and amaze you, especially when compared to the dearth of pollinator activity on non-native landscapes. Don’t be surprised if you start seeing more insect-eating birds such as warblers, Eastern Phoebes, and Eastern Wood-Pewees. They will certainly notice and take advantage of the opportunity.
When planning your mini meadow, don’t forget grasses. Somewhere between 40% and 70% of meadow plant species are some sort of grass, a term used here to include sedges, rushes, and grasses. All grasses are wind pollinated, so you won’t see the same level of pollinator interaction as with the native flowers listed above. But grasses are nevertheless essential to the wildlife of a healthy meadow.  Their dense roots, which you will only fully appreciate the first time you try to dig up a native grass plant and move it, help stabilize the soil, prevent erosion, corral assertive native flower species, and tamp down weeds. Birds use grasses for nesting materials. Monarch butterfly larva can use grass stems for cocooning. Grasses are host plants for skipper butterflies. The list goes on. They provide support and protection for many birds, insects, and other small meadow critters living in, on, or close to the ground.
You can find out more about garden-worthy grasses on the Plant NOVA Natives website. Good bets for your mini meadow include Broomsedge, Eastern narrow-leaved sedge, and Little Bluestem.
You won’t have to go far to find native meadow flowers and grasses for sale. Many sellers are close to where you live. Northern Virginia is fortunate to have several native-only garden centers. In addition, one-day native plant sales are held across the region in the spring and fall. Also, conventional garden centers now supply more native plant options than ever given the growing consumer demand.
No matter how modest or ambitious your plans may be, taking the first step to build a mini meadow habitat is what matters. Your new native plantings will expand meadow-like habitats, increase meadow-loving life, and ultimately improve the biodiversity of the region.

How a Return to Tribal Management is Restoring Landscapes, Webinar, May 21st

Tuesday, May 21, 2024
7 pm
Register here.

Tribal people have lived in North America for at least 10,000 years, shaping how the landscape evolved and functioned. During that time, they developed cultures and traditions that stressed the obligation tribal people had to the foods, medicines, and places that sustained and defined their way of life. However, disease and settlement disrupted the balance, replacing it with the extractive management approach that has dominated the landscape for the past three centuries. On May 21, discover how a return to tribal practices can help restore that balance. Cody Desautel, executive director of the Confederated Tribes of the Colville Reservation in northern Washington State, hosts our next Life on a Sustainable Planet webinar. He’ll reveal how the last 50 years have seen a resurgence of tribal self-determination, and how indigenous knowledge is helping reestablish healthy relationships between people and the land.

Discover stories of hope and resilience every month, at the Smithsonian Environmental Research Center’s (SERC) free webinar series! SERC’s monthly science talks highlight the research and conservation that are leading us to a more sustainable future, featuring scientists from the Smithsonian and around the world. They air on Zoom every third Tuesday of the month at 7pm Eastern, January through October, unless otherwise noted. All of their talks are recorded. By signing up online, you’ll be able to watch live and receive a link to the recording after the event. Closed captions available at the event and on the recordings.

The Amazing Camp Zama Hornet’s Nest

Photos and article by FMN Stephen Tzikas

Every now and then I see a wasp building a mud-based tubular shaped nest in some corner of my home’s front door portico. These are mud dauber wasps. Mud wasps are solitary wasps, which means it builds a single nest for itself.  They are fairly common and the internet has photographs of their nests.  That got me thinking about the most magnificent insect nest I’ve seen.

While serving as the Chief, Environmental Management Office for the US Army in Japan, I had many partners and stakeholder on the installations. One of them,

Close-up of the hornet’s nest from Camp Zama, Japan

in the same Directorate of Engineering and Housing as my office, was Buildings and Grounds.  In the pre-internet age, we visited other offices in person to conduct business, and the live interaction was always valuable and rewarding. During one visit to the Buildings and Grounds Office on February 10, 1993, some of its employees came back with a nice catch from someplace on the installation.  It was the largest hornet’s nest I ever saw.  I didn’t know it at the time, but years later after I took the photographs, I would be in a much better position to appreciate them as a Master Naturalist.

Hornets are a type of wasp, though wasps typically are paper wasps and yellow jackets.  There are differences in the way the insects build their nests.  Hornets construct nests using chewed wood and saliva and can take months to build, giving it a papery look.  Hornet nests are also much larger than wasps nests, being larger than a basketball size.  If you ever encounter such a nest, be careful.  Hornets can sting repeatedly, and may cause allergic reactions that can be life threatening.  If you discovered such a nest on your property, it may be wise to have a professional exterminator address the problem.  Hornet nests are structured in a closed architecture, that is, the nest has a surrounding envelope, with a small opening at the bottom of the nest.

Paper wasps also create nests out of a paper-like product of maceration.  Paper wasps nests may have an exterior that looks less elegant, a sort of conglomeration of parts and crater-like surfaces often lacking an envelope. A yellowjacket wasp nest will have a single opening, but these wasp nests are usually in the ground, and only visible as a small hole in the dirt.

Upon returning to the US in 1994, I worked at the Washington Navy Yard for a couple years.  One of Naval installations under our responsibility was the Patuxent River Naval Air Station in Maryland.  At least on one occasion if not more, I drove out to the location for an environmental evaluation. Runner up to the Camp Zama, Japan, hornet’s nest were the termite mound nests at this Maryland location.  I recall they looked nearly as high as humans, but in some parts of the world they can be 25+ feet.  Besides those tall termite mounds, I saw many wild turkeys and large bulb eye insects nearly a couple inches in length.  I was beginning to think about what an unusual place this Patuxent River area was.

 

William Ramsay Science Night

William Ramsay Elementary in Alexandria is an interesting facility, housing the school, a recreation center, and the Buddie Ford Nature Center. Hosting the first annual Science Night was a natural neighborhood outreach for the school. They were indeed a gracious host too providing dinner, signage, and setup assistance for all the volunteers.

FMN’s connection to the event is Peter Jones, an FMN member and EL teacher at William Ramsay. FMN responded to Peter’s call for volunteers with two nature related topics.

Tom Blackburn donned his Audubon hat and provided a colorful interactive presentation on “Birds and Beaks”. Jerry Nissley was there with “Turtle Talk”, a fun-fact-filled show and tell display focused on Woodland Box turtles.
The event was set up in the rec-center gym and included tables on a myriad of environmental topics such as Energy Concepts, Water Cycle, Climate Action, and Air Quality Technologies. On the nature side, Buddie Ford Nature Center, Geology and Minerals, Entomology (drawers of awesome bugs from USDA collection housed at Natural History Museum), Pollinators, Spotted Lantern Fly, and the aforementioned Birds and Turtles all had tables.

Vesta Nelson, Science Coach at Ramsay followed up with a message to the volunteers saying, “WOW! We had over 300 visitors last night.  We weren’t getting a lot of feedback about kids attending, so I really didn’t think it was going to be that big.
THANK YOU, THANK YOU, THANK YOU! Words cannot express how thankful I am because you all really did an AMAZING JOB! The kids learned a lot!  I couldn’t believe what they remembered. We do shout outs at our school and the 4th and 5th graders gave us a lot of shout outs! WOO HOO! I’m so pleased with how it turned out.”
