FROM CLASSES TO PLANTINGS TO RESEARCH, CASEY TREES' FALL PROGRAMS HIGHLIGHT

TH E VALU E OF TREES


CASEY TREES NEWS IN BRIEF

Casey Trees gears up for fall planting season Casey Trees is about to make more than 350 trees — and 26 sites in the D.C. area — a little happier through its Community Tree Planting (CTP) program. The first tree will be put in the ground on Sept. 27 at The Kingsbury Center, one of 10 schools receiving trees this fall. New Citizen Forester (CF) recruits will learn how to properly plant trees and lead volunteers from experienced CFs at the National Zoo planting on Oct. 6. All other volunteer opportunities begin Oct. 27. The full schedule is available on Page 10. School plantings and some special planting events are closed to outside volunteers. Advanced registration is required and is available on a first-come, first-served basis. No tree planting experience is necessary to participate. For individuals interested in re-treeing the District in ways other than tree planting, check out Page 7 for more on how to sponsor a tree planted this year through the CTP program.

CASEY TREES NEWS CONSTRUCTION AT TREE PLANTING ANNEX NEARS COMPLETION | The new building at 3015 12th Street NE, which will house Casey Trees’ Tree Planting Department and its tree yard, is almost complete. Finishing touches will be made during the month of September. TWO STAFF RECEIVE ARBORIST CERTIFICATION | Arborist-Auditor Katie Heffernan and tree planting crew member Josh Singer passed their International Society of Arboriculture (ISA) exams and are now certified arborists. The new certifications bring the total number of ISA-certified arborists on staff to eight. SUMMER VOLUNTEERS HELP CARE FOR D.C.’S TREES | Last month, dozens of volunteers helped water, weed and mulch trees planted by Casey Trees in the past two years. On Aug. 6 and 7, a group of British teenagers helped care for trees at Oxon Run Park in Ward 8. Each teen raised more than £4,000 for the Joshua Foundation and were rewarded with a two-weeks-long community service trip to the U.S., with stops in New York, Chicago and Washington, D.C. In another tree care event on Aug. 11,

From the Desk From Vision to Reality: Aligning D.C.’s tree functions to achieve Mayor Gray’s 40 percent tree canopy goal Mayor Gray has received much deserved praise for his Sustainability Plan and 40 percent Tree Canopy Goal. To attain it, Casey Trees urges Mayor Gray to review the city’s current tree management activities and the agencies that carry them out. The two key agencies involved in tree related activities in D.C. are the District Department of Transportation (DDOT), and within it the Urban Forestry Administration (UFA), and the District Department of the Environment (DDOE). Their missions are as follows:

MARK BUSCAINO

EXECUTIVE DIRECTOR

• DDOT: Develops and maintains a cohesive sustainable transportation system that delivers safe, affordable, and convenient ways to move people and goods while protecting and enhancing DC’s natural, environmental and cultural resources. Within DDOT… • UFA: Establishes and maintains a full population of healthy street trees. • DDOE: Improves the quality of life for the residents and natural inhabitants of the Nation’s Capital by protecting and restoring the environment, conserving our natural resources, mitigating pollution, and educating the public on ways to secure a sustainable future.

4

Although these statements are clear, history, not mission, often dictates tasks, which is why UFA for example, administers D.C.’s tree protection law, often called the Tree Bill. While the law impacts trees almost exclusively on private space, UFA is tasked with street tree management on the public space. The net impact is that administering the Tree Bill on private lots interferes with UFA’s ability to carry out its primary mission managing street trees, and UFA has suggested that DDOE assume Tree Bill oversight to streamline agency functions. Another administrative alignment issue concerns the D.C. State Forester’s Office, which is housed in UFA. Given UFA’s mission, the D.C. State Forester oversees exclusively street trees, different from every other state forester office, which oversees all trees and forests in their state. By extension, federal funds provided to the DC State Forester’s office are used almost exclusively on the city’s street trees as opposed to all of D.C.’s trees. Finally, the State Forester’s Office is supposed to support and convene an Urban Forest Council to encourage coordination of a state’s management of its trees and provide the public a voice into urban forestry-related matters — a key element of Mayor Gray’s Sustainability Plan. Unfortunately, since 2002, D.C.’s State Forestry Office is the only state forester’s office in the U.S. that does not have an Urban Forest Council, which muzzles the public voice, discourages Agency coordination and encourages inefficiencies and waste.

September 2012 | theleaflet


DDOE plants trees on private lots through its stormwater programs, conducts tree planting for stream stabilization and other performs activities. It reviews construction plans that impact trees, is responsible for regulatory compliance to the EPA for tree-related issues and coordinates writing and implementation of the city’s Urban Forest Master Plan — a requirement of the city’s MS-4 Stormwater Discharge Permit. DDOE has had its Urban Forest Master Plan draft ready to go for years, but because of agency struggles, it has never been finalized. These issues have slowed D.C.’s progress toward a greener future, and we urge the Mayor to take the following steps: 1. Revise UFA’s mission to include tree management on schools, parks and other DC public spaces. This is a huge job that plays to UFA’s strengths, recognizes their current role and will enhance the quality and quantity of trees on public space. 2. Shift Tree Bill and Tree Fund oversight to DDOE, both of which impact private space. This will clarify roles and cement DDOE’s mandate and activities on the private space including tree planting, development plan review and related tasks.

4. Task DDOE to establish and regularly convene an Urban Forest Council to give the public a voice in D.C.’s tree issues and to coordinate agency activities to reduce redundancies and inefficiencies in managing the District’s urban forest on all lands. 5. Finally, relocate the D.C. State Forester’s Office to DDOE, which is charged by its enabling legislation with establishing, coordinating and meeting tree policy on all D.C. lands, not just its street trees. The Mayor’s Sustainability Plan and its 40 percent tree canopy goal are ground breaking, and to achieve it, the city must modify its existing organizational structure to eliminate overlapping responsibilities, inefficiencies and waste. These simple actions will have a significant positive impact toward achieving the goal and will represent a quantum leap for the future of this, our City of Trees. Regards,

Mark Buscaino Executive Director

3. Assign coordination of all-lands tree policy, done by no agency at present, to DDOE as required by its enabling legislation.

Spotlight Citizen Forester Theresa Jenkins does her name proud Since her days in high school, Citizen Forester Theresa Jenkins has embraced her nickname: Tree.

project leaders and a diverse group of volunteers, all whom have similar aspirations, optimism and expectations for improving the District’s canopy.”

A Brookland resident, Jenkins would regularly pass Casey Trees’ headquarters on 12th Street NE and was curious to see what the organization was about.

One of the greatest aspects of tree planting is working with the Casey Tree Staff, the dedicated project leaders and a diverse group of volunteers, all whom have similar aspirations, optimism and expectations for improving the District’s canopy.

“I loved the name,” she said, “and I was actively looking for a volunteer opportunity that would benefit many aspects of the city, while doing something I love.” Jenkins’ first taste of Casey Trees came in May 2011, when she a took a tree tour of Capitol Hill. “I wanted to know more,” she said, “so I quickly attended several classes and tree plantings and became a Citizen Forester later that year.” Being outdoors and helping improve the environment play important roles in Jenkins’ life — and her volunteer service with Casey Trees — but it is the community aspect of tree plantings that keeps her coming back for more.

Jenkins is vocal about her support of the city’s tree canopy and the work she and others do to protect it. Though she understands the importance of planting, she often talks with people about advocating for trees in communities. “Trees are important to the health and well-being of all District citizens,” Jenkins said. “Plus, planting trees is a great way to get connected to the city you live in.” Do you want to become a Citizen Forester? Register online for the Citizen Forester-qualifying Tree Planting Workshop on Oct. 6.

Tree Planting Tree Rebates up to $100 per tree available By Katie Heffernan, Arborist-Auditor, Casey Trees | Fall is a great time to plant, and Casey Trees’ popular Tree Rebate program continues to offer do-it-yourself tree planters big rewards during tree planting season. Any individual who plants a tree on private property in the District can receive a rebate from Casey Trees for up to $100. There is no limit on the number of trees that a person can be rewarded rebates for. Rebates of up to $50 per tree are available for small and medium canopy trees, including standardsize fruit trees and native flowering trees like silverbell or yellowwood. Most trees qualify, as long as they reach 15 feet tall and wide at maturity. Dwarf trees and shrubs — even large shrubs — do not qualify for the rebate. Invasive tree species — Norway maple, Tree-of-heaven, Mimosa, Bradford pear, Sawtooth oak and Siberian elm — and any variety of ash should not be planted and do not qualify for the rebate.

Casey Trees will approve the full rebate amount for purchases more than the rebate tier amount, or the full retail price of the tree for purchases that are less than the rebate tier amount. Note that trees must be planted on private residential and commercial 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 online.

A selection of 27 large, native canopy trees qualify for the $100 rebate — primarily oaks and hickories, as well as American beech, American linden, American sweetgum, sycamore and tuliptree. Rebate requests must be accompanied by a completed form pledging to water and care for the tree(s) for a minimum of two years, as well as an itemized receipt for each tree.

Education TreeWise sees greater engagement in second summer of program By Liz Ball, Volunteer Coordinator, Casey Trees | With a successful second season under its belt, TreeWise, Casey Trees’ summer youth enrichment program, embodies the idea that teaching children early on about the urban forest can make them more informed tree stewards in the future. TreeWise, formerly called Arbor Kids on the Go, was launched last summer. The approach is unique — TreeWise counselors hit the road and bring fun and engaging environmental education lessons to youth ages six to 13 enrolled in summer programs in the District, Maryland and Virginia. This summer, counselors Alex Kemp, a senior at The George Washington University, and Michelle Ramirez, a senior at the University of Maryland at College Park, taught more than 500 students a curriculum filled with lessons, activities and games to further the their environmental awareness and knowledge. Lessons included many hands-on activities, including “Water and Trees,” where students learned about the important relationship trees have with water, especially in our urban environments, and tested their knowledge in a relay race. “It was hands down our most popular lesson this summer,” Ramirez said. “There is no better way to reinforce what the kids learned than with a race that tested their knowledge retention.”

12

Overall, Ramirez and Kemp visited a total of 14 different groups in five Wards and Maryland, including Bridges Academy, CentroNía Bilingual Charter School, Grace Episcopal Day School, Jan’s Tutoring House and The Lowell School. The students at these camps participated in some of TreeWise‘s 80-plus sessions this summer!. “TreeWise was the greatest educational experience of the summer,” said Rene Davis, a staffer at the Bridges Academy. TreeWise will begin scheduling camps early next spring. Find out more about the program and application requirements online or email inquiries to treewise@caseytrees.org. Would you like to get your children outdoors learning about trees and the benefits they provide? Give them the seed hunt guide on Page 16, or find more downloadable activities online.

Technology & Research New research projects signal departmental changes By Jessica Sanders, Director of Technical Services and Research, Casey Trees | As the focus of the department changes from geographic resources to technical services and research, a new long-term plan is being developed and implemented. Research is integral for evaluating current practices and developing methods to inform and improve future programs. The Technical Services and Research (TS&R) Department has a few projects queued up this year, including urban tree mortality, urban ecosystem services analysis (iTree) and establishing growth models and projections of trees planted in various soil scenarios Planting trees is key to Casey Trees’ mission. Department staff have altered the previous tree mortality study to incorporate a more scientific approach. By tracking tree progress and mortality, TS&R staff can build mortality contingency tables. These contingency tables will make it easier to track the difficult urban environment that trees live in, providing appropriate data for Casey Trees staff to use while analyzing management practices to increase tree survival rates. They also help define an establishment period for urban trees in the District. This establishment period is the hardest portion for a tree, the growth can be very inconsistent, and mortality is high during this period. When trees have consistent growth from one year to the next, a tree is

theleaflet | September 2012

considered established. Urban trees are often planted in very compacted or fill soils, which make growing conditions very harsh. Because of this, there have been various techniques and products over the years to create a more habitable environment for trees in cities. These products have never had a direct comparison in one geographic area using one tree species. This year, Casey Trees staff have the opportunity to observe these variables using trees planted 8 years ago. This exciting research will not only provide insight to the scientific and planning community, but it will also be a way of assessing methods for future site remediation. The mission of Casey Trees was an important factor in changing departmental direction, and trees planted in the future will be given greater opportunities to thrive as TS&R enters a new chapter of research. Join Jessica on Sept. 13 as they discuss tree canopy issues in this month’s Tree Talk Thursdays online chat.

Planning & Design Development Tracker: St. Elizabeth’s East Campus in Ward 8 By Lisa Morris, Planning Associate, Casey Trees | The D.C. government is working to transform the historic, 180-acre east campus of St. Elizabeth’s Hospital into a new hub of activity east of the river. A possession transfer between the federal and D.C. governments initiated master planning process. Released earlier this summer, the master plan proposes a mixeduse development that would repurpose most of the historic buildings as well as add new buildings. Currently, the site has about a 32 percent tree canopy cover, slightly below the city average of 35 percent. If the plan is built, about 12 acres of canopy will be lost to new development, reducing the tree canopy to around 25 percent. The loss of trees and addition of impervious surface will perpetuate problems such as stormwater runoff and water and air pollution. With careful attention, the District can capitalize on this development opportunity while mitigating for

14

the canopy loss that the development plans require. First, the development team should design tree spaces that are large enough to facilitate street tree canopy growth. Soil volume recommendations range from 400 to 1,000 cubic feet, depending on the species and sidewalk width. Silva cells under the sidewalk can extend rooting space for street trees to help them reach their full potential. Second, we recommend setting a tree canopy goal to ensure that the canopy that will be lost is made up for throughout the development. For a development of this density, a 35 percent canopy goal would be ambitious but achievable. Large scale developments such as St. Elizabeth’s East provide an opportunity to bring new employment, residential and retail opportunities to the District’s residents. They also provide an opportunity to create more sustainable and beautiful neighborhoods by planning for a healthy and extensive tree canopy.

Tree Care Casey Trees encourages summer tree watering, fall weather preparation This summer has been hard on the District’s trees, as much of the area has been affected by moderate drought conditions. To help residents ensure their trees are receiving the proper amount of water, Casey Trees will continue to issue its weekly watering recommendations through the September. The Farmer’s Almanac forecasts a fairly warm September, with two inches of rainfall — 1.5” below average — furthering the region’s recent dry spell. And although summer is still upon us, the first day of autumn — Sept. 22 — is right around the corner and it is never too late to get your trees ready for the seasonal transition. Fall is ideal for planting new trees — receive up to $100 per tree through our Tree Rebate program. The mild weather also makes it easier to prepare existing trees for the cooler months. By the end of the month, Casey Trees encourages you to: • Continue watering. Practice 25 to Stay Alive — 25 gallons of water per tree per week in times of little or no rainfall — through the month of September. Do not water after the ground freezes.

theleaflet | September 2012

• Remove slow-release watering bags. Tree trunks and the tree flare need to be exposed to air, so once October arrives, remove any watering devices and store them until next spring. • Check the mulch. Freshen mulch by adding two to three inches in a ring around the trunk. Be sure to practice the 3-3-3 rule — three inches of mulch in a three-foot ring with a three-inch space around the tree trunk. Casey Trees offers tree-care resources online and through its course offerings and Tree Talk Thursdays online chat.
