Clarendon Willow oaks are pruned by County foresters

Eric Wiseman, Associate Professor of Urban Forestry and Arboriculture at Virginia Tech has released a study on the benefits of Arlington County’s street tree inventory. Key findings are:

• Arlington has an estimated 20,355 street trees
• The five most abundant street tree species are willow oak, red maple, Japanese zelkova, pin oak, and Callery pear
• Each year, Arlington’s street trees intercept over 28 million gallons of rainfall and sequester over 4 million pounds of carbo dioxide
• In total, Arlington’s street trees provide over $2 million in benefits annually or roughly $105 per tree
• The replacement value of Arlington’s street trees is estimated at nearly $36 million
