Native Plant Sales are Booming

Interest in using native plants in our yards has been growing over the past decade, gradually at first, and suddenly exponentially. It has long been known that native plants are critical to the ecosystem, and now thought leaders in the landscaping industry have taken up the cause of promoting them for our yards. Public gardens have set aside sections to demonstrate their value in the landscape, and gardening magazines are touting them in every edition. Garden centers have responded to the increase in demand for natives by increasing the diversity of plants available for sale.

When COVID struck last year, new gardeners flocked to garden centers in droves. As the country has started to open up this spring, sales have soared even higher. A very significant chunk of those increases has gone toward native plant purchases. The landscape designers and owners of garden centers that specialize in native plants have been exhausting themselves to keep up with the demand.

Why are native plants so particularly popular? We may be reaching a tipping point in acceptance of personal environmental responsibility, as the populace is finally facing the reality that our ecosystem is teetering in the balance and that the time to take action is now. Our own properties are a place where we can make a palpable difference by using locally native plants to support birds and other wildlife. Many of the new gardeners are younger and particularly attuned to the value of gardening not just for beauty but for a greater purpose. At the same time, the industry has had time to experiment with native plants and figure out where they do best in a landscape setting. It is now easy to find the plants and choose the ones best suited to a given landscaping need.

Several years ago, representatives of environmental organizations and governmental agencies got together to create Plant NOVA Natives, a campaign to promote the use of native plants in Northern Virginia. One strategy has been to provide a plant guide and resources on the Plant NOVA Natives website, with simple suggestions for every planting situation along with more details for those who are interested and even more details for landscape professionals. The other strategy has been to essentially deputize everyone who hears about the value of native plants to spread the word. One section of the website shows how to reach out to neighbors, community associations and faith communities. The website also lists the garden centers that only sell native plants – an introduction to three of those specialty nurseries is on this short video – as well as twenty-one conventional garden centers where volunteers for the campaign have been putting red “Northern Virginia Native” stickers on plants.

All in all, Northern Virginians are discovering that gardening to support nature has never been easier. Once healthy landscaping practices are adopted, the sight of a yard dancing with butterflies is enough to sell the native plant concept all by itself.

Plant NOVA Natives Needs Volunteers!

/in , /by

Plant NOVA Natives encourages residents as well as public and commercial entities to install native plants as the first step toward creating wildlife habitat and functioning ecosystems on their own properties. Lots of volunteers are needed!

Please email [email protected] if you can help with any of the following positions:

More people to help put their red Virginia Native stickers on plants at conventional nurseries. A very fun way to learn about plants!

For their upcoming five year native tree campaign:

—Put on a launch event in September or October– Can you arrange a tree-related events (plantings, talks, walks, giveaways, etc.) during that period? They would like to advertise multiple events all over Northern Virginia.

—Help with the legwork for their launch period –  They need someone to correspond with potential event organizers and put it all onto a calendar.

—App creator– Can you create a very simple app to pair with the My Trees Count website? They will be asking people to record their tree plantings (in fact people can record them now) on the state website and would like an app to make it more mobile friendly.

—Social media volunteers – They need one or two people to take the lead on regular postings on various social media sites.

—Someone to send press releases – They need an ongoing “press office” to collect contact info for all the local media outlets then send them occasional press releases, starting with our launch month.

Audubon Afternoon: How Birds Adapt their Songs to Urban Noise and What We’ve Learned during the Pandemic, Dr. David Luther, June 6th

Register here.

Audubon Society of Northern Virginia will hold its annual membership meeting virtually, on Sunday, June 6 from 3:00 to 3:15 PM. The membership will vote on incoming Directors and new terms for Officers.

At 3:15 PM, they will welcome Dr. David Luther to their Audubon Afternoon. Urban environments are among the most highly modified habitats on the planet. David’s research has focused on how human activity has modified habitats and altered ecological processes around the world. Acoustic communication is a critical component of reproductive success in many species. His lab at George Mason University studies how human noise affects the behavior and survival of a diversity of bird species.

Quantify the benefits of trees with i-Tree and help NASA too!

/in , /by

Article by FMN Kim Schauer

MyTree is one of the many tools within the iTree suite of free online tools that uses peer-reviewed, USDA Forest Service research to quantify the benefits and values of trees,  and iTree’s tools will get a software update on May 3 that will embed the latest USFS science.

You can get an itemized list of ecosystem services (and an estimate of the monetary value of those services) by visiting the MyTree online app and entering details about the species, health, size and location-relative-to-your-home of your specific tree.

For example, MyTree indicates that a 40″ diameter sweetgum in excellent health in full sun within 20′ of a Mt. Vernon home that was built between 1950-80 on its northeast side:
• intercepts 1,594 gallons of rainfall annually
• avoids 247 gallons of runoff annually,
• sequesters more than 13 lbs. of carbon dioxide annually,
• saves 192 kWh of electricity in reduced air conditioning costs annually
• has stored 30,277 lbs. of carbon dioxide over its lifetime.

MyTree is a helpful tool to give evidence that just leaving a tree standing and/or hiring a certified arborist to protect and preserve a tree can be a worthwhile investment. This tool is mostly meant to analyze individual trees.

A few of the other tools in the suite include:
   –iTree Design (for parcel-level analysis)
   –iTree Canopy (use aerial photos to estimate benefits of trees)
  –iTree Hydro (to quantify stormwater benefits)
  –iTree Species (estimate the benefits of different species)
   –iTree Planting (quantify future benefits of a new tree-planting project) 

As a side note, anyone who is collecting tree data with MyTree might also be interested in learning about NASA’s very cool citizen science project, GLOBE Observer: Trees. Using the app helps NASA improve and ground truth satellite data and track biomass gains/losses.

The GLOBE Observer: Trees app

   1.  Open the GLOBE Observer: Trees app.
   2.  Take a photo of a tree.
   3.  Walk to the tree (so the app can record the distance).
   4.   The app calculates the estimated height of the tree.
   5.  Enter more optional data to add to the value of your observation.
   6.  Contribute to to NASA scientists’ understanding of the world’s canopy!

Below is an excerpt from the GLOBE Observer: Trees webpage:

Tree height is the most widely used indicator of an ecosystem’s ability to grow trees. Observing tree height allows NASA scientists to understand the gain or loss of biomass which can inform calculations of the carbon that trees and forests either take in from or release into the atmosphere. Tracking how trees are changing over time can help us estimate the number of trees that make up an area.  Learn more about the science of trees, and how NASA studies them, on the Trees Science page.

Here’s a 4/21/21 article about it:

Article and photo of Sully by FMN Marilyn Parks

Two of my favorite things come together in Ellen Reid’s SOUNDWALK, nature and music.  Ok, three of my favorite things since I get to bring Sully!  

Wolf Trap Park offers two trails that take hikers through the winding, woody parkland behind the Filene Center.  SOUNDWALK is GPS-enabled work of free public art that uses music to illuminate the natural environment.  It has been tailor-made to its setting and encourages calm reflection and introspection as you follow the blue (2.5 miles) or orange (1.5) trail markers.  The sun was gleaming on Wolf Trap Run, the woods alive with spring growth.  Take time to look at the Redbud and Dogwood trees in bloom, the spring beautifies popping up through the forest floor.

Ellen Reid SOUNDWALK was co-commissioned by the New York Philharmonic, Saratoga Performing Arts Center, Wolf Trap Foundation for the Performing Arts, Mann Center for the Performing Arts in association with The Fairmount Park Conservancy, and the Britt Festival Orchestra.  For more information on specific presentations, visit ellenreidsoundwalk.com.

Now through September 6, 2021 at Wolf Trap National Park for the Performing Arts.  Free.  If you go, download the app before you arrive at the park and remember to bring your earbuds – not everyone wants to hear music as they’re walking the trails.

Note that the Ranger Station is closed and due to construction projects, many areas of the park are closed in the interest of public safety.  Face masks are required on NPS administered lands where physical distancing cannot be maintained.

Sustainable Diet, Sustainable World: Community Supported Agriculture Makes Both Happen

/in , /by

In her article on the Knowledge Driven Enterprise blog, Savanna Smith reports that “When you buy your groceries, the best and brightest fruits and veggies have usually traveled across the country and sometimes across the world to get to you. This supply chain bypasses the perfectly fresh produce local to your community. Our traditional market practices have enormously high transportation and carbon costs, create massive amounts of wasted food, and may leave our local farmers with unsustainable businesses.

So what can we do to address these problems?”

Smith discusses community supported agriculture options in Northern Virginia and elsewhere. And she offers a great list of resources for further reading.
