As part of Mayor Bloomberg's plan to plant one million new trees in the city by 2017, volunteers took to parks in Staten Island, the Bronx, Brooklyn and Queens yesterday to add another 20,000 to that number. About 3,500 trees were planted in Van Cortlandt park alone. More places for the coyotes to hide!

The trees are needed not just to add to the city's greenery but to replace the number of trees that were downed in September's storm. Funds for the replacement trees come from MillionTreesNYC, which says almost 3,500 trees were damaged in the storm; reports said that in Park Slope there was almost one downed tree per block. People can donate or learn about volunteer opportunities on the site.
