MillionTreesNYC (Parks & Recreation)
As part of the Mayor's PlaNYC initiatives, the New York City Department of Parks & Recreation and New York Restoration Project (NYRP) developed MillionTreesNYC, a citywide initiative to plant one million new trees in New York City's public and private spaces over the next ten years. Launched in October 2007 in collaboration with community, non-profit, government and corporate partners, MillionTreesNYC supports a robust stewardship program to sustain the long-term health of NYC's urban forest, as well as systematically catalog tree plantings and their care. Other core elements of the MillionTreesNYC initiative include community outreach, public education and advocacy. MillionTreesNYC also introduces individual home-owners, building owners and management, and residential and commercial developers to a land manager education program that promotes the health, environmental and economic benefits associated with planting and maintaining trees.

MillionTreesNYC Training Program (Department of Parks & Recreation)
Launched in November 2008, the MillionTreesNYC Training Program is a 7-month green collar job training program in support of the MillionTreesNYC initiative. The objective of the MillionTreesNYC Training Program is to help disengaged young adults aged 18-24, a target population of the Mayor's anti-poverty efforts, develop marketable employment skills to meet the growing need for qualified "green collar" professionals in the arboriculture and landscape industry as a result of MillionTreesNYC. Instruction in arboriculture, ecological restoration, and garden restoration and design is provided through in-the-field training at the Parks Department and New York Restoration Project. The Program also relies on the collaboration of other MillionTreesNYC non-profit partners including the New York Botanical Garden which provides a customized educational curriculum in botany, horticulture, forestry, and soil science for the participants, and the Lower East Side Ecology Center, Trees NY and others who provide certificate training.

The High Line (Department of Parks & Recreation)
 The High Line is a new public park built atop a 1930s elevated freight rail structure on Manhattan's West Side. Running 1.45 miles in total, the High Line's first section (from Gansevoort Street to 20th Street) opened to the public on June 9, 2009. It has been under the jurisdiction of the Department of Parks & Recreation since 2005, when it was donated to the City by CSX Transportation.

Friends of the High Line, a community-based 501(c)(3) non-profit group was formed in 1999 when the historic structure was under threat of demolition. Friends of the High Line worked with the City to preserve the structure for reuse as an elevated public open space through the federal railbanking program. The non-profit now works as a conservancy, in partnership with the Parks Department, to maintain and operate the park. Significant funds are being raised privately by Friends of the High Line, as part of the operating agreement with the Parks Department.

The High Line's new park landscape was designed by a team led by James Corner Field Operations, with Diller Scofidio + Renfro. The park design is inspired by the wild, self-seeded landscape that grew up on the High Line when the trains stopped running.

Gracie Mansion
The Gracie Mansion Conservancy is a private not-for-profit corporation established in 1981 to preserve, maintain, and enhance Gracie Mansion - one of the oldest surviving wood structures in Manhattan and a member of The Historic House Trust. The Conservancy's mission is to raise funds to restore and maintain the historic structure and acquire furnishings that illustrate the rich history of New York; improve the surrounding landscape and gardens; and provide educational services, including publications and tours.

Tours are offered on Wednesdays at 10:00 am, 11:00 am, 1:00 pm, and 2:00 pm; $7 for adults, $4 for seniors, students free. Group tours are also available. To make reservations for individuals or groups, to volunteer or to help support the Gracie Mansion Conservancy, please call 311 (or 212-NEW-YORK outside of New York City).

Additionally, a book titled "Gracie Mansion: A Celebration of New York City's Mayoral Residence" was published by Rizzoli through the Gracie Mansion Conservancy. Written by Ellen Stern, the book gives a terrific account of the House as the home of New York City's mayors and their families, beginning with Fiorello La Guardia in 1942. Anecdotal portraits of all of Gracie Mansion's mayoral residents are provided. The book also details the 2002 restoration that transformed Gracie Mansion into the "People's House" under Mayor Michael R. Bloomberg. The pages of the new book are illustrated with letters, maps, designer's sketches, and never-before published photographs of the historic interiors of the House. Books are available for purchase by calling 311. Proceeds from the sale of this publication will help support the Conservancy's tour and educational programs.
