Casey Trees celebrates Park(ing) Day in D.C.On Sept. 16, Casey Trees turned two metered parking spots in Dupont Circle into an instant park to promote the environmental, social and financial benefits of trees as part of Park(ing) Day 2011.

Casey Trees’ park design replaced 320 square feet of impervious surface normally off limits to pedestrians with an abstract forest open to the public. Oversized tags touting the financial and environmental value trees bring to D.C. residents were attached to surrounding trees.

“We are pleased with the attention our Park(ing) Day installation attracted,” said Mark Buscaino, Executive Director of Casey Trees. “The event was a perfect opportunity to engage District residents about the benefits of trees and the urban forest.”

PARK(ing) Day is an annual event that brings together activists, artists and citizens to temporarily transform parking spaces into public parks. In 2010, more than 800 parks in more than 180 cities in 30 countries were created.

Summer's Rainfall shortage shows in Casey Trees' weekly watering alertsJuly 2011 was the hottest month

on record in Washington, D.C., which was apparent in Casey Trees’ summer watering alerts.

All four of July’s weekly recommendations — part of Casey Trees’ 25 to Stay Alive watering initiative — were “Dry.” When “Dry” conditions are posted, residents should give their trees the recommended 25 gallons of water per tree.

Watering alerts were issued every Monday from May 8 to Sept. 26.

“Dry” conditions happened most often — 10 out of 21 weeks — with “Normal” conditions coming in a close second at nine weeks. “Normal” alerts denote optional watering for the week.

The only “Wet” condition, meaning no watering is necessary, occurred in early September when the remnants of Tropical Storm Lee dumped nearly seven inches of rain on D.C.

Casey Trees’ newest downloadable tree walk will guide you through

the streets of Capitol Hill near Lincoln Park.

Although Pierre L’Enfant had grand plans for this site, Lincoln Park was initially used as a dumping ground until being developed as the site of Lincoln Hospital during the Civil War. In 1867, it was designated as a park to commemorate President Lincoln and the Freedmen’s Memorial that you see in the center of the park today was installed and dedicated in 1876, funded entirely by freed slaves.

Tree walks for the National Gallery of Art Sculpture Garden, Tudor Place and the Franciscan Monastery are also available online at no cost.

Casey Trees marks one year in BrooklandCasey Trees moved into its new headquarters in the heart of Brookland one year ago. We are grateful for the warm welcome and look forward to being an integral member of this wonderful community.

Casey Trees will welcome nearly 60 cyclists who will be riding into

the District Saturday, Oct. 8 on the second to last leg of the 20th annual STILH® Tour des Trees, a weeklong, 485-mile cycling tour benefiting the Tree Research and Education Endowment Fund (TREE Fund).

Casey Trees is a co-sponsor of the 2011 STIHL® Tour des Trees. The seven-day tour originates in Virginia Beach and stops in Williamsburg, Richmond, Charlottesville, Front Royal and Reston before concluding in D.C. Cyclists participate in tree planting and public awareness events at each stop.

“Casey Trees is proud to be a Silver Sponsor of the 2011 STIHL Tour des Trees,” Executive Director Mark

Buscaino said. “By supporting the Tour des Trees we are investing in urban forestry research that will significantly benefit the District’s urban forest and its neighborhoods for generations to come.”

In D.C., cyclists will participate in a tree planting at the U.S. National Arboretum and visit Casey Trees’ headquarters for lunch and tours of the site’s bioretention planters and green roofs. The tour concludes at The American University Woods-Brown Amphitheater at 2:00 p.m. with closing ceremonies immediately following. Chuck Leavell, keyboardist for the Rolling Stones, will serve as keynote speaker and join The Tom Principato Band to entertain the crowds.

Tour des Trees rides into the District Oct. 8

Site tours available through First FridaysFirst Fridays is a new series presented by Casey Trees’ Planning and Design department to introduce individuals, particularly design professionals, to sustainable urban design that incorporates trees.

October’s session focuses on trees and bioretention and will highlight curbside bioretention and innovative ways to maximize curbside root space for trees under sidewalks.

Details: Friday, October 7; 12:30 p.m. Advance registration required; space is limited. Lunch is provided.

When putting a price tag on the value of a tree, we often talk in the abstract: things like improved air quality, cleaner water and higher property values are among the many benefits that we list when “calculating” the return on investment trees can offer us. But unless you have visited a nursery recently, the costs associated with planting a tree may not be evident.

At Casey Trees, we plant 2- to 2.5-inch caliper trees — an industry standard for street trees that we have adopted because of their ability to better withstand urban conditions. The cost to Casey Trees to purchase, transport and plant such trees is $250 per tree (see illustration).

We understand that the environmental benefits of trees far outweigh their monetary cost which is why we offer our trees — and related tree care materials — at no cost to groups. However, after 10 years and more than 10,000 trees planted across our nation’s capital, we are now asking for your help.

Donations of any amount make a difference; however, we hope you will consider sponsoring the planting of one tree this fall with a gift of $250.

Fall in D.C.Fall is upon us and the District’s trees never disappoint. Starting in mid-October, trees in our area will begin to explode into brilliant reds, oranges and yellows before falling dormant for winter.

Three pigments are responsible for this impressive show - chlorophyll, carotenoids and anthocyanins. Chlorophyll gives leaves their familiar green color; carotenoids produce yellow, orange and brown colors; and Anthocyanins add color to red apples, blueberries, cherries, strawberries, and plums. They are water soluble and appear in the watery liquid of leaf cells.

Both chlorophyll and carotenoids are present in the chloroplasts of leaf cells throughout the growing season. During this time, chlorophyll is produced and broken down and leaves appear green. As days get shorter, chlorophyll production slows down until it stops. The green color is no longer visible, and other pigments present (carotenoids) with the chlorophyll are then revealed. During autumn, bright light and excess plant sugars produce anthocyanins within leaf cells.

Observe the city’s transforming treescape on one of our docent led tree tours by foot or bike, by volunteering at an upcoming Community Tree Planting event or when visiting a nursery to select a tree to plant at home.

District's trees to peacock in October

Best time to plant trees is nowSpring prompts most to think about making major improvements to their yards, but fall — October through December — is actually the ideal time to plant trees as they enter dormancy during this period.

When selecting a tree from a nursery

or garden store, look for the following:

• Healthy foliage. The tree’s crown, or canopy, should make up two-thirds of the tree.

• Tree stem and branch condition. There should be a strong central leader and branches should be

nicely formed and no larger than two-thirds the diameter of the trunk.

• Tree damage. Make sure the tree is free of pests and the trunk has no injuries.

• Trunk form. Tapered trunks withstand more stress.

Tree Rebate now offers up to $100 per tree for select large canopy trees, $50 for most othersCasey Trees now offers rebates up to $100 per tree to individuals who plant large canopy trees on private property in the District. Seven genera and 27 species — mostly native hickories and oaks — qualify for the increased rebate. Rebates of up to $50 per tree will continue to be available for small and medium canopy trees.

“Our Tree Rebate program has been tremendously successful in helping us advance D.C.’s 40 percent by 2035 Urban Tree Canopy Goal,” said Jim Woodworth, Director of Tree Planting. “By offering an increased rebate amount, we hope to incentivize residents and business owners to plant more large canopy trees because they provide greater environmental benefits than ornamental and smaller-growing trees.”

The program, funded by the District Department of the Environment, provides rebates to individuals who purchase and plant a tree on private property in D.C. Rebate requests must be accompanied by a completed form pledging to water and care for the tree for a minimum of two years and a purchase receipt for each tree.

“While rebate forms may be submitted year-round, the best time to plant trees is in the fall and spring months,” Woodworth added. “Trees planted in the summer may not be able to withstand the heat stress experienced in this region.”

Invasive tree species, including Norway maple, Tree of Heaven, mimosa, Bradford pear, Sawtooth oak and Siberian elm and the Ash tree should not be planted and do not qualify for the rebate. Dwarf trees and shrubs are also ineligible.

Additional program revisions allow for the rebate to be submitted for trees planted on nonresidential property in D.C. and the elimination of the three trees per property maximum. Trees must continue to be planted on private property and not on public property such as in street tree boxes, triangle parks or traffic circles.

Downloadable rebate forms, instructions and a complete list of trees eligible for the increased rebate are available at www.caseytrees.org/rebate. Participating area nurseries are also listed.

By offering an increased rebate amount, we hope to incentivize residents and business owners to plant more large canopy trees because they provide greater environmental benefits than ornamental and smaller-growing trees.

Oct. 1 marked the first day of the fall Community Tree Planting (CTP) season. Casey Trees, with the help of hundreds of volunteers, will plant more than 380 trees at 28 sites across the District.

Individuals enrolled in the Tree Planting Workshop, a qualifying course for Casey Trees’ Citizen Forester program, planted the first trees of the season on the grounds of The Catholic University of America as part of their field training.

Citizen Foresters serve as volunteer tree ambassadors to the community on behalf of Casey Trees and teach new volunteers how to properly plant and care for trees. The Tree Planting Workshop is a free continuing education course offered to the public.

Scheduled sites include a military base, community garden, marina, at-risk youth housing and eight schools. Of note, the Charitable Foundation of the Energy Bar Association will sponsor the planting of 10 trees at Capitol Quarter, a new park in Southeast along the riverfront.

“We look forward to working with volunteers of all ages and abilities this fall to restore the District’s tree canopy,” Executive Director Mark
