About the Wild Plant Nursery

The Wild Plant Nursery is a unique resource for ecological restoration in the greater Washington, DC, area. Established in 2001 in Springfield, Virginia, under an agreement with the Fairfax County Park Authority, the nursery is the region’s most comprehensive source of local, wild native-plant material (“local ecotypes”). The use of local ecotypes is a standard best practice in ecological restoration because that helps to safeguard genetic diversity and local adaptation in the species planted. The nursery is currently working with about 340 species, some uncommon or rare in the wild in this region. For many of these species, their nursery is the DC area’s only source of production — local ecotype or otherwise. All plants are grown from seed (or spores) that they themselves collect, from over 50 local natural areas. (They collect only with permission.) The nursery serves their own planting programs, as well as those of area governments, schools, businesses, and other conservation nonprofits. They rely on volunteers to run the nursery! To join them, check the Volunteer page for our Field Schedule. Please note that their nursery and office addresses are different. The Wild Plant Nursery is located at 6100 Cloud Dr. in Grove Point Park (formerly known as Franconia Park), Springfield. Our office is located in Annandale but is not open for plant sales.

*NVSWCD Workshop*
Sugarland Run Stream Monitoring Workshop

When: Thursday, May 2, 3:00-6:00pm
Where: Sugarland Run Stream Valley Park, Herndon/Sterling

This site is located near one of the largest great blue heron rookeries (breeding/nesting areas) in the eastern US. Volunteers often find plenty of newly hatched young crayfish in the spring. This is also the most accessible stream site, which can be easily reached by wheelchair and/or other assistive tools over a paved path. Learn more and register for this workshop and others here.

*NVSWCD Workshop*
Little Difficult Run Stream Monitoring Workshop

When: Saturday, May 11, 1:00-4:00pm
Where: Fred Crabtree Park/Fox Mill Park, Herndon

This small stream is located in a peaceful wooded park a short hike away from the parking area. Little Difficult Run often scores very highly on the macroinvertebrate index because its watershed lies almost completely within the protected parkland. Reaching this site requires hiking through the woods and over uneven terrain. Learn more and register for this workshop and others here.

*NVSWCD Workshop*
Quander Creek/Dyke Marsh Stream Monitoring Workshop

When: Thursday, May 16, 9:00am-1:00pm
Where: Mount Vernon District Park, Alexandria

Volunteers monitor a small tributary of Dyke Marsh twice this spring in partnership with the Friends of Dyke Marsh. This is the District’s only muddy bottom stream, all others use the rocky bottom protocol. You will see a lot of cool crane fly larva and dragonfly larva here! Reaching this site requires walking through the woods and over uneven terrain. Space at this workshop is limited. If you’re interested in joining us, please email Ashley.

*NVSWCD Workshop*
Horsepen Run Stream Monitoring Workshop

When: Thursday, May 23, 3:00-6:00pm
Where: Horsepen Run Stream Valley Park, Herndon

This site has undergone a lot of change over the last few years! While it had become more challenging to monitor this site in the past, recent changes to the streambed have brought more riffles to monitor and we’re excited to see how this changes the macroinvertebrates we may find! This is an accessible stream site, which can be reached by wheelchair and/or other assistive tools over a paved path (there is a moderate slope). Learn more and register for this workshop and others here.

 

More Training and Stream Monitoring Opportunities

The NoVa Soil & Water Conservation teams are  very excited to contribute their stream data to state and national datasets. If you’d like to see data from all the NVSWCD regional stream monitoring team’s active sites, you can find our organization on the Clean Water Hub.

Spring Native Plant Sale at The Clifton Institute, May 18th

Saturday, May 18, 2024
11:00AM – 2:00PM

The Clifton Institute
6712 Blantyre Rd
Warrenton, VA 20187

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. Since fall 2019 The Clifton institute has been collecting seeds of native grassland plants from around the area, which means in addition to being native they are of local ecotypes. At the plant sale they will sell seedlings grown from these seeds of a variety of perennial wildflowers, native grasses, and a few trees. Some of their favorites include butterflyweed, upland ironweed, scaly blazing star, narrow-leaf mountain-mint, and gray goldenrod. Partners from other organizations will also have plants and merchandise for sale. They will accept credit card, cash, or checks made out to the Clifton Institute. Hope to see you there!

In 2022, The Clifton Institute started a research project to study what habitats Box Turtles use at different times of year. This will help inform researchers and other landowners about the best time of year to mow fields and do other land management practices that might disrupt or even kill Box Turtles. On this second installment of Science Saturdays, participants will help get the 2024 season started by looking for turtles that were radio-tagged last year as well as potentially finding new turtles to tag. This is a special opportunity to tag along with the staff researchers and see how field science is done.

The Tree Trimming Scammers

/in , /by

Article by Cindy Speas, Chair of the Fairfax County Tree Commission

The doorbell rings, and at your door is a young man who says, “Hello, I was driving by and noticed your trees need some pruning. I’ve been working at your neighbor’s house, and thought I’d stop and offer you the same deal!”

It must be spring. We often hear about telephone or online financial scams, but what about the “woodchucks” or tree scammers that arrive at your door? These are seasonal workers, usually untrained, uncertified, and unlicensed.  Beware! They come bearing disaster for our trees, as well as our wallets.

Last spring Fairfax County posted a great article about the tree trimming scam. One police officer is quoted as saying this is “one of the most pervasive criminal problems this county is facing right now.” It happens in all seasons, of course, when trucks drive by looking for accessibility ramps or seniors working in their yards, or in spring seeking “unkempt” yards. So, if you have a yard full of native plants and little lawn, and you wait for just the right time after winter to clean up your beds, you could be a target.

These folks are not arborists and may remove living wood or, at worst, “top” your healthy tree. When the growing end of every tree limb or branch is lopped off, the tree can lose as much as 75% of its leaves, which provide a majority of the tree’s food. When a tree is weakened by less food and water, it becomes vulnerable to insect, sun and wind damage. These stresses mean that the tree may not survive the butchering. When you see a lot of fast growing shoots where major limbs were cut, that is a major sign of stress and poor health. Many municipalities and counties have great resources for resisting this fraudulent behavior. Here’s one from Fairfax County: https://www.fairfaxcounty.gov/publicworks/trees/plant-care. It’s one thing to spend—or even overspend­—on taking out a dead limb, but quite another to fall for the “just let us prune your trees and everything will be fine” pitch. And don’t forget, untrained workers may use spikes on their boots because they are not taught the best practices of a reputable tree care specialist. This is highly damaging to the health of your trees.

Our trees are critical to our quality of life, and to the economic value of our homes, but they are threatened by “woodchucks.” Become informed about tree care—a good arborist can be as valuable to the life of your tree as a good electrician or plumber is to the life of your home. It is worth taking the time to find out if these solicitors are licensed and insured, certified in their area of expertise, and have good recommendations. Compare and weigh the costs and benefits of particular work that you know you need—don’t take the cheapest and easiest course of action. Be a good consumer and do the research. Just say NO to the door-to-door solicitor and yes only to the company YOU call that has good reviews, an arborist on staff, and free initial consultations.

Beware! Your beautiful trees are counting on you to speak for them and protect them.

 

Build a Mini Bird Sanctuary

/in , /by

Article by Plant NOVA Natives

The best sanctuaries for birds are undisturbed expanses of forests and meadows. Anyone can see that those are rapidly disappearing in Northern Virginia, and where they remain, they are rapidly shrinking below the size needed for many bird species. Those in charge of any patch of land can help some of these birds by adding plants to expand the habitat value of nearby parks and natural areas.

The partnering organizations that together make up Plant NOVA Natives are inviting individuals and communities to participate in a “Bird Sanctuary Planting Weekend,” October 25-28. People will be installing native canopy trees and understory plants all on the same weekend, all across the region, in a big celebration of trees and the natural world. In Fairfax County, the first twenty faith communities to apply will receive a free “mini bird sanctuary” – a native canopy tree and two native shrubs – assuming they have an appropriate location, as confirmed by volunteers who will be doing site visits to help the communities evaluate their properties for opportunities to improve habitat.

What does it take to provide sanctuary for birds? The first requirement is that the plants be native to the local ecosystem. This is because the diet of baby birds consists primarily of caterpillars, and most caterpillars can only eat the plants with which they evolved. By far the biggest source of food for caterpillars is the leaves of large native shade trees, by virtue of their immense canopy compared to smaller plants. The second requirement is to provide food for the adults. Adult birds also require caterpillars and other bugs for protein. They also need the seeds and fruits from the smaller native trees, shrubs, vines, and flowers that are tailor-made for their nutritional needs (unlike those of many non-native plants.) Different bird species feed and nest at different heights from the ground, so native plants are needed at all levels. You may notice, for example, the preference of sparrows and robins for the ground layer, bluebirds for the shrubs, bluejays higher still, and woodpeckers in the canopy. (The fact that some birds require the lower levels is the reason why it is so imperative to keep cats indoors.)

Another reason to install native plants at the ground layer Is that many of those caterpillars feeding up in the trees spend part of their life cycles sheltering on the ground. They cannot find the habitat they need in mounds of mulch, not to mention in lawns where they get chopped up by lawn mowers. What does provide shelter is native perennials and dead leaves.  So once you have your trees and shrubs in place, you can have the fun of exploring the numerous native groundcover options, gradually expanding the landing pad out to the drip line as the trees grow.

Volunteers Needed: Habitat Restoration Project at Occoquan Bay NWR, April 20th

Saturday, April 20, 2024
1:00 PM – 3:00 PM

Occoquan Bay NWR
14050 Dawson Beach Road
Woodbridge, VA, 22191

This program is part of the Stretch Our Parks initiative, in partnership with the staff of Occoquan Bay National Wildlife Refuge.

On Saturday, April 20, help remove invasive garlic mustard from a meadow in the refuge. Volunteers will partner with Refuge staff, Audubon volunteers and neighbors to make more space in the meadow for native grasses that birds love!

Garlic mustard’s roots release chemicals that alter the important underground network of fungi that connect nutrients between native plants, inhibiting the growth of important native species. Luckily it can be easily removed – but there is a lot of it! Learn more about Garlic mustard here.

No experience necessary! The staff will show you how to identify and remove Garlic mustard. Trash bags will be provided. The area may be muddy so please bring rain boots or waterproof shoes, and gardening gloves if you have them.

Meet at the Central Parking Lot, not at the Visitor Information Center lot. Registration recommended but not required, please feel free to bring a friend!

Tuesday, April 23, 2024
7:00 PM – 8:00 PM

Virtual Seminar
ASNV Member ticket: $10 (Non-member ticket: $20)

Registration required!

Did you know you don’t even need binoculars to explore the big world of birds? Often it is faster and easier to identify a bird by its song – if you know how to bird by ear. In this program, Colt Gregory will:

  • explain the many benefits of birding by ear

  • introduce some of the most common birds by their songs and calls

  • share resources and apps to help you practice and improve your birding by ear skills.

This program is intended for beginning birders but may be a helpful refresher for more experienced birders. This program welcomes children aged 10+ if they are accompanied by a participating adult.

Colt Gregory is a member of the Audubon Society of Northern Virginia, Northern Virginia Bird Club, and Arlington Regional Master Naturalists, serving on ARMN’s Training Committee. Colt co-leads the weekly Sunday bird walks at Great Falls National Park and leads several routes in regional Christmas Bird Counts. He enjoys hiking, camping, and birding during both. He believes that Audubon programs provide a better understanding of the relationships among plants, animals, and the environment while giving us all opportunities to volunteer, educate, and learn.

Colt will lead an optional field trip in northern Virginia on Saturday, April 27, 2024, at 8:00 AM for up to 15 local Birding by Ear participants. The fee is $30 per person. Click here to register for the field trip. The field trip is first come, first served, and there will be a waitlist. The field trip will be in Great Falls, VA. The exact location will be shared only with field trip registrants.
