From the Council on the Environment of NYC website:
MillionTreesNYC, through the generous sponsorship of American Express, has 1,250 FREE trees available for adoption by homeowners and community groups. Trees will be distributed by New York Restoration Project (NYRP). Note individuals and families are limited to adopting one tree per household; and all tree recipients are required to register their new tree at www.milliontreesnyc.org. Interested community groups that can plant and care for 5-10 trees should contact before October 18th.
(a shout-out to those of us who rent:) For residents who do not have their own yard to plant a tree, information on volunteering, educational programming and contributing to MillionTreesNYC will also be available.A variety of trees of different sizes, including flowering and medium and large canopy (shade) trees will be available. MillionTreesNYC horticultural staff will be present to provide advice on which species tree is best for your home.
Sounds good to me. In fact, I'll be happy to assist with the care and maintenance of a tree if it means I can let my kid run around your yard a couple of times a week. Seriously, let me know!
