asey Trees is now accepting applications for its eighth annual High School Summer Crew jobs program, which will run from June 20 to August 12, 2011.

Selected students will travel by truck or bike in teams to sites across all eight Wards to water, weed and mulch trees that Casey Trees has planted in the last two years. When not caring for the District’s trees, crew members participate in a

series of career development activities, such as tree climbing at the U.S. National Arboretum and digital mapping at the National Zoo, profiling their experiences on Casey Trees’ blog, Tree Speak.

Applicants must be 16 years or older, be enrolled in or just graduating high school in the D.C. area, demonstrate an interest in the environment and be willing and able to work outdoors in all weather conditions with a variety of landscaping tools.

Applications must be completed online in one sitting by May 1. Crew member finalists participate field tryouts in May, when they experience the type of work they would be doing in the program, which has graduated 94 high school students since 2002.

In addition to caring for the District’s trees, Summer Crew members participate in other activities, such as tree climbing at the U.S. National Arboretum.

More information regarding the program, including the online application, can be found on the Casey Trees’ Education webpage.

New legislation will impact stormwater management in D.C.

C

Every year, one billion gallons of untreated stormwater combine with oil, dirt and trash from D.C. streets, and then mix with raw sewage to flow into our rivers. Currently, the city’s waters are unfishable, un-swimmable and hostile to diverse ecosystems that once thrived. In recent years, new environmental regulations and design standards have helped improve the quality of our waterways.

The District’s sewer system, designed 300 years ago, sends both combined waste water and sewer water for treatment before entering the river. When too much rain falls, the water bypasses treatment and empties directly into the river.

Increased development leads to more stormwater runoff, and simultaneously decreases the amount of trees and other vegetation, which help absorb runoff.

To better manage the overrwhelmed 2

n less than a decade, Casey Trees has planted more than 10,000 trees, educated thousands of adults and children on the value of urban forests, developed cutting edge online mapping tools, and partnered with elected officials, developers and community groups to implement best construction practices that protect existing trees and add new ones.

Although we have accomplished a lot, much more work remains. We need your help.

Access points in the curbside along 12th Street NE allow stormwater to infiltrate bioretention planters and pass into Casey Trees’ rain garden.

asey Trees and its Planning & Design department are working to add trees to stormwater designs to help increase the District’s tree canopy and simultaneously clean its rivers. Stormwater management has become a big issue in recent months, with the implementation of a new fee system and a dispute that ended in Congressional legislation.

system, the District started charging landowners a fee for the amount of stormwater runoff produced on their property.

The federal government, which occupies about 20 percent of the District’s impervious surface area and is also tax exempt, refused to pay the fees claiming they were taxes. However stormwater fees are incurred for using the sewer system, just as an electricity bill is a fee for using electricity. In response, Congress passed a bipartisan bill in December (S.3481), requiring the federal government to pay the sewer fees.

Newly embraced design principles incorporating plants to absorb stormwater before it runs into the sewers are finding their way into local development projects with greater frequency.

Directing stormwater runoff to irrigate landscapes helps conserve energy and save potable water. Casey Trees’ two rain gardens at our new headquarters are examples of this type of design.

PRUNING ELMS I

n January, nearly 30 Citizen Foresters and Casey Trees staff attended two tree care workshops at Dangerfield Islan, where they learned how to properly prune American elms. The classes were held in conjunction with the American Elm Restoration program and taught by U.S. National Park Service horticulturist Barry Stahl.

Stahl grows the classic American elm species (Ulmus americana), the Jefferson and Washington elms and the disease-resistant cultivars Valley Forge, Princeton and New Harmony, propagated from elm cuttings.

Winter is the ideal season for pruning because the trees are dormant, as well as the insects and diseases that take advantage of open wounds. Pruners tended to young trees — generally 10 to 12 feet tall — nipping out dead and broken branches, removing branches that were too low and establishing strong central leaders, or stems. theleaflet | February 2011

Stahl teaches six steps of pruning: •

Remove broken, diseased and dying branches.

•

Select or create a central leader and cut back or remove competing branches.

•

Select and establish the lowest permanent branch (depends on the tree’s location).

• Select scaffold branches and remove competing branches and plan for proper spacing • Select temporary branches below the lowest permanent branch.

• Before you make a cut, connect with the tree, feeling the ground around it and touching its bark, reassuring the tree that pruning is good for it.

Citizen Forester spotlight: Gregg Serenbetz

Y

ou can say Gregg Serenbetz has planted his volunteer roots with Casey Trees.

Gregg was one of the first Casey Trees volunteers, participating in the street-tree survey in 2002. He enjoyed his experience and became a Citizen Forester when Casey Trees began planting trees the following year. As he planted more frequently and became familiar with other CFs and the Casey Trees staff, he decided to try his hand as a Lead Citizen Forester.

Plantings have provided him an opportunity to see different neighborhoods across the District, and when he passes a tree he has planted, he gets a feeling of satisfaction.

“Volunteering with Casey Trees has been one of the best things I have ever been involved with,” Serenbetz said. “I know I’m doing something beneficial in the long run — helping to re-tree D.C. Every tree I plant will provide exponential benefits in the years to come.”

He has enjoyed building relationships with his fellow CFs and Casey Trees staff, whom he refers to as his “tree cult” when he discusses his volunteering with friends and family.

These friendships, and the bonds he makes with the communities he plants in, deepen his devotion and interest in planting trees.

“The incredible warmth and appreciation community groups often display towards Casey Trees and the volunteers during events still surprises and encourages me,” he said.

Serenbetz said he was at the top of one category among his fellow Citizen Foresters: he’s the muddiest.

Planting dates will run from March 5 to May 7.

“One constant throughout all of the plantings I’ve done is that somehow I usually always end up with dirt on my face,” he said. “I’m not sure if that’s funny or interesting, but I do take pride in it!”
