Arlington’s Tree Canopy Fund Survey

These trees planted in 2009 are now taller than the apartment building!

In 2008, the Arlington County Board created the Tree Canopy Fund (TCF) to ensure funds contributed by developers who cannot meet tree planting requirements on their sites will be used to plant trees on other private property.  Since then, 1,686 saplings have been planted throughout Arlington under the oversight of the Urban Forestry Commission (UFC).  The program is managed by Arlingtonians for a Clean Environment (ACE) and trees are planted by a professional tree care contractor. TCF provides larger trees planted by professionals (these root balls weigh 300 – 500 pounds, and trees are 6 feet tall!), sizes more appealing to condos, apartment managers and homeowners seeking immediate impact for the front yard and sidewalks.  Since planting larger trees professionally is more costly than providing tree whips, TreeStewards were asked to conduct a tree survey in the summer of 2017 to determine the program’s effectiveness.

Over 25 Tree Stewards along with some Master Naturalists were instructed on how to score trees on the survey sheets and told not to enter private property without permission. They were assigned neighborhoods and fanned out over the entire county to search for and assess the trees planted during the last 8 years. Volunteers also distributed educational information to homeowners on how to remove ivy from trees, correct mulching and other topics.  In many cases, volunteers rang doorbells or left notes offering to discuss tree care or ask permission to enter a backyard to better rate a tree.  Other volunteers entered the data collected and assisted with the final analysis.

Arlington Oaks received an oak.

  • 1,372 trees or 81.3% were found by the survey volunteers. A tree that was “not found” could mean the tree could not be observed and rated because of a fenced yard or the tree location listed was not clear.  What we do know is that less than 19% of trees planted through the TCF program have died.
  • 88% of the trees found were rated in “Good” condition. This shows that most residents who have received planted trees under the program take care of their trees. Trees were planted throughout Arlington at single family homes (49%), multifamily properties (49%), and nonprofits (2%).

The Tree Canopy Fund also funds education efforts. The 2012 community education campaign to remove ivy from trees allowed Tree Stewards and Master Naturalists to hire a professional communications firm that has resulted in more than 22,000 internet visits and 5,000 pieces of printed material distributed.  In 2018, a community campaign encouraging preservation of mature trees will be conducted by Tree Stewards. Materials will be developed by the same professional communications firm and tested on Arlington homeowners focus groups in February with campaign starting in late March.

All of the Tree Canopy Fund programs depend on volunteers for their success. Arlington residents learn about the free tree offers from notices in civic association newsletters and other media, yet it is committed volunteers who go door to door encouraging neighbors and apartment managers to apply for trees that have had the best success.  Education on tree care in the community is promoted by Arlington’s active volunteers.

The  young trees planted so far under the Tree Canopy Fund programs will require decades before they can replace the tree canopy lost by the removal of large trees during development, yet it is a start.

TreeStewards select saplings for the spring 2018 planting to ensure quality trees.

Christmas Tree Choices: Living, Cut, or Artificial

After 50 years of reuse and recycling, this artificial tree is green!

‘Tis the season in which many believe the holidays would not be complete without a decorated tree. For those who care about their own environmental impact, the good news is you can follow your traditional celebration with a clear conscious! Just remember the environmental golden rule to Reduce, Reuse, and Recycle whatever your choice. Below are points to consider:

Artificial Trees create a larger carbon imprint at the beginning, yet with yearly reuse and not purchasing new models, this can be spread out over a long time.  The tree to the left is basically a wooden pole with green wire bristles from 1960 – so old it is now chic, and holds 50 years of family history.

Add a Free Native Tree

Sassafras albidum

Sassafras albidum

Trees have many benefits. They provide shade, beauty and tranquility, cool the air, soak up greenhouse gases, emit oxygen, and help to shelter and feed birds and other wildlife. Native trees are especially important because they can support a huge number of native insects and caterpillars, which is what songbirds feed their young. Caterpillars also turn into beautiful butterflies and moths.

So if you can do only one thing for nature, plant a native tree. Or, if you live in Arlington, have one planted on your property at no cost to you through the Tree Canopy Fund.

Attend a meeting from 7 to 8:30 p.m. Monday, Nov. 6, at Shirlington Library, 4200 Campbell Ave., Arlington, to learn more about the tree canopy fund and how you can apply for a robust tree to be planted on your property next spring. The application deadline is Dec. 15, 2017.

For a list of the 11 available species followed by photos and additional descriptions of each tree, click: TCF 2018 Spring Species

Tree Stewards will help you select the right tree for the right place right at your home.

The Silent Killer in Your Yard

What’s scarier than bumping into a spider web, a witch, a black cat or a bat in the dark of All Hallows Eve?

It’s a zombie plant that harbors rodents and mosquitoes on the ground but morphs into a killer of earth’s largest living ancient species when it climbs and matures. Still stumped?

It’s English ivy, which can choke – and kill — the beautiful trees that give our yards and neighborhoods shade and character. What looks like a lovely little green plant can clamp onto trees, accelerating rot, and causing mature trees to fall down during storms.

Ivy can strangle trees, and once it is in the tree canopy, it can block sunlight from the trees’ leaves. Dense ivy cover deprives the tree’s bark of normal contact with air and microorganisms and competes with the tree for nutrients and water. Ivy is a threat. But we can beat it with simple landscaping work.

3 Steps to Remove Ivy from Trees

1. Use garden clippers to cut ivy at the bottom around the entire trunk of all infested trees. The goal is to separate all ivy vines from their source of nutrients in the soil so they will die. If the ivy is not dense, you can pull it from the soil at the bottom of the tree with your hands, especially soon after it rains. On heavily infested trees with ivy vines thicker than an inch, you will need to carefully saw through the vine and carefully, gently ease it away from the bark. Experiment with the tools below to find what works best for you.

TIP: Wear gloves and long sleeves to lessen the risk of poison ivy. Many prefer doing this during the winter months when poison ivy is less virulent, and they will have heavier clothing to reduce the risk.

2. Pull all ivy vines out of the ground around the base of the tree, making a “life saver ring” 2 feet wide all around the tree. This will protect the tree from future infestations. This is easiest to do when the soil is soft from rains; if the ground is very hard and the vines keep breaking, wait until after a rain to remove the vines. The cleared space allows you to see any emerging ivy from roots you missed. Arborists suggest laying a 2″ thick leaf or wood chip mulch for three feet around the tree to preserve moisture in the soil and keep lawn mowers from getting too close to the roots. Keep the mulch 3″ away from tree trunk to ensure air exchange for the bark, and you can spot any ivy trying to reinfest the tree.

3. Once cut, leave ivy on the tree. Do not pull it off because that could harm the tree. Ivy will gradually blend into the tree bark after it is cut. Check up your tree each winter to be sure the ivy remains off.

Please note that ivy’s leaves grow larger and more heart-shaped as the vine climbs up the tree. This mature phase of the plant produces flowers in late summer and purple berry-like fruit in autumn that birds eat and spread far from the initial source. If you’re uncertain about the identity of the vine on your tree, track a stem of it back to ground level until you are certain it’s English ivy. Then follow the steps above to kill its vines on the tree trunk.

Can This Tree Be Saved?

How about it, Tree Stewards and arborists?

What’s your prognosis for an Eastern redbud Cercis canadensis ‘Forest Pansy’ with a see-through split trunk? Click each image for a better view:

This perky redbud caught our fancy as we conducted the census of specimens planted by Arlington County’s Tree Canopy Fund in the Langston-Brown/Halls Hill neighborhoods. It was decked with plastic Mardi Gras beads, and its owner said that in New Orleans, such bejeweled trees are called “Tree of Life.”

Our tree, however, has several problems. Obvious is its mulch volcano. And although the strands of beads are lightweight, they could burden the branches.

CLUE: Our tree had crossing branches. The one on top sprouted from the back of the larger branch it is weighing down. The trunk split near where these branches originated.

When we examined the trunk, we found that it had been badly split long enough ago for the heartwood to have dried. Tell us what you think!
