Millions of Trees at Risk in Northern Virginia? Introducing Tree Rescuers!

Northern Virginia’s oldest and best-loved trees are in danger, and the threat is in plain sight – and yet there are few who can see it.

But help is on the way! Tree Rescuers – a new community education and outreach program – is shining a light on non-native invasive vines, which pose a mortal threat to millions of mature trees in Northern Virginia.

More than 130 people from neighborhoods across Northern Virginia have already volunteered with Tree Rescuers, a new campaign sponsored by Plant NOVA Trees and aimed at preserving our area’s mature trees.

“We were amazed at how many people were ready to do something like this for the trees but didn’t know how to get started,” said Margaret Fisher, one of the coordinators of Plant NOVA Trees. “This is a great time to start, since the leaves are down and the vines can be seen more easily.”

As many as three million trees in Northern Virginia may be at risk, said Fisher.

Many people are unaware that invasive vines like English Ivy can eventually make a tree hazardous (and expensive to remove). Tree Rescuers volunteers learn how to identify problematic vines, then walk their neighborhoods spotting trees that need help.

The Tree Rescuers don’t remove any vines themselves, but they warn landowners by dropping off a brochure explaining the problem and ways to fix it.

Data gathered by Tree Rescuers will also help improve knowledge of the actual number of trees at risk, since the collected data is being aggregated and mapped. A map of neighborhoods surveyed can be viewed here.

Tree Rescuers is part of Plant NOVA Trees, a five-year campaign by local governments and nonprofit organizations to increase tree cover in Northern Virginia. Native trees are a key part of the solution to many community problems, from extreme weather and air and water quality to the health of birds, wildlife, and the Chesapeake Bay.

Fairfax County Watershed Cleanup, Various Dates

The Nature Conservancy is partnering with Fairfax County Park Authority to do a wonderful watershed cleanup around 15 different Fairfax County parks!

Registration for the annual Fairfax County Watershed Cleanup is now available at They need nearly 500 volunteers to help clean up plastic bottles, cans and other debris. It’s a great way to give back to the community, and it’ll be a pretty fun day as well!

Event capacity is limited, and they request that you register individually or in family units. Before registering a large group of 10+ people, please double check that everyone in your group is committed and will attend. This prevents situations where one group takes half the available spaces and then cancels last-minute, and they have no one to fill in.

Plastics! Plastics! Everywhere.

Article and photos by FMN Mike Walker

Like last year, I saved every scrap of “plastic” that came in to my home in January and February. Fortunately I have a wonderful screen porch to store this stuff outside during the cold weather. As you can see above, in two months, I collected a shocking total of about 60 cubic feel of “plastic” stuff, ranging from bubble wrap, packaging waste (even from organic products) prescription bottles, shrink wrap, etc. I even had a plastic hose from my washing machine, plastic “throw-away” sunglasses from the doctor for eye dilation and plastic clips from ink for my printer. A real potpourri of plastic trash.  My wife and I do not go out of our way to buy plastic products, of course, I submit that we are typical consumers. Collecting two months worth of material is a vivid reminder of what is coming into our lives and how difficult it is to avoid an avalanche of plastic material.

After two months of collecting,  I sorted the plastic into what can actually be recycled….see my picture below….a small fraction of waste…15 bottles and some caps. While manufacturers offer “helpful” codes on the bottom of many plastic products, most plastic is simply not recyclable and in Fairfax County becomes waste to be incinerated.

Being aware of our use patterns for “stuff”…whether it be plastic, water consumption, gasoline or other resources is the first step in becoming aware of our impact on the earth and the search for serious reductions in consumption. Taking the time to simply collect the plastic that comes into your home for a period of time can become a real eye opener to the sheer volume and variety of plastics – including non-recyclable plastics – that are encountered everyday. It can really make you mindful to look for ways to reduce your consumption, too.

The Northern Virginia Bird Club offers three guided bird walks a week at a variety of locations.  The trips are free and open to all.  There is no need to register for the local trips.

Here is the schedule for March – June 2022.

Spring Native Plant Sales

Native plants provide better food for insects, which in turn provide food for birds. You can make a huge difference for wildlife by planting native species on your property.

Virginia Native Plant Society maintains a list of native plant sales in the area.

Not on the list, but worth considering is Loudoun Wildlife Conservancy’s Native Plant Sale, which takes place on April 16, 2022 in Morven Park in Leesburg.  More information is here:

Spring in Washington, by Louis J. Halle

Photo:  Barbara Saffir

Reviewed by FMN Kristina Lansing

After a cold, grey winter, spring once again is on our doorstep. If you’re chafing to get outside but are finding conditions still a bit less than hospitable, try curling up instead with “Spring in Washington.”

“In the year the atomic age was born, a young man on a bicycle appointed himself monitor of spring in the nation’s capital. Starting before sun-up each morning, he pedaled miles and saw much before his workday began at the offices of the State Department. That the year was 1945 is of no importance, for the events he chronicled could have taken place in 1845 or 2045. The rites of spring are eternal.”*

Consider traveling back in time to experience what Washington was like back in 1945. Join author Louis J. Halle on his daily forays to the the Tidal Basin, Rock Creek Park, Dyke Marsh, Theodore Roosevelt Island, and the C&O Canal. Rock Creek was less visited back then and Dyke Marsh, lacking a boardwalk, was essentially off limits to all but the hardy and adventurous. A passionate observer of nature, Halle documents in detail the migration of birds, the awakening of foliage, and the changeability of the wind and the local weather. Written in the style of Aldo Leopold, but speaking very much with his own voice, Mr. Halle reflects not only on nature but on foreign affairs and the human condition. It’s a timely read for many reasons.

This book, which numbers just over 200 pages, is no longer in print but copies can readily be found in the Fairfax County Library system or for purchase via Amazon and Alibris. If at all possible, do try to snag a copy that features the illustrations of American artist Francis L. Jaques, as his drawings truly are delightful.

Louis J. Halle was born in New York City and educated at Harvard University. In 1979 he received the Audubon Naturalist Society’s Paul Dartsch Award for outstanding contributions to the field of natural history.
