MillionTrees NYC Research

Welcome to MillionTreesNYC Research. In addition to citywide tree plantings, volunteer engagements, and public programs, studying the effects of increasing tree canopy on urban ecosystems and various related fields is essential to our mission. The MillionTreesNYC Advisory Board Research & Evaluation Subcommittee works to coordinate efforts between researchers and policymakers towards a better understanding of New York City's natural environment.

The Urban Field Station at Fort Totten: A Collaboration between the USDA Forest Service and New York City Department of Parks and Recreation

New York City Parks and USDA Forest Service Northern Research Staff work together on various research projects related to MillionTreesNYC at the New York City Urban Field Station, a collaborative facility that supports scientists from both agencies as well as visiting researchers.

Urban Field StationUrban Field Station staff are involved as members of the MillionTreesNYC advisory committee as well as the Research & Evaluation and Tree Planting & Stewardship subcommittees. In this spirit of facilitating research, an urban forestry and ecology bibliography was created in support of the MillionTreesNYC project. This project was initially conducted by Northern Research Station personnel at the request of the MillionTreesNYC campaign, with guidance from the MillionTreesNYC Research Committee. The bibliography file can be used with most commercial bibliographic software. Last updated August 2011.

In support of MillionTreesNYC, Northern Research Station staff has compiled a comprehensive Urban Forest Bibliography (PDF, 678 KB) of ecological studies and research sources.

MillionTreesNYC, Green Infrastructure, and Urban Ecology:
A Research Symposium

March 5th and 6th, 2010
New York City

Thanks a million to all those who participated in our 2010 Research Symposium! The New School venue was filled to capacity as over 200 researchers, practitioners, and environmental enthusiasts took in presentations on subjects ranging from assessing large-scale reforestation efforts to stormwater management to green roof hydration. An extensive poster session offered attendees insight into the latest developments in urban ecological research. Special thanks to our seven invited speakers whose presentations offered insight into ecological projects taking place in Chicago, Los Angeles, Boston, Phoenix, Stockholm, and New York City.

A total of 55 research papers and posters were presented during the MillionTreesNYC Spring Research Symposium. We've included a list of the presenters and their respective study topics in the comprehensive Symposium Research Abstracts (PDF, 1 MB) document. Please feel free to browse these submissions, which bolster the growing body of knowledge on urban ecology and green infrastructure.

Cities And The Environment (CATE) Journal Issue on MillionTreesNYC Research

In order to continue the momentum initiated by our spring 2009 Research Workshop and March 2010 Symposium, the editors at Cities And The Environment (CATE) Electronic Journal have collaborated with MillionTreesNYC to release a special edition of their publication which reflects many of the contributions from our partners in research.

Executive Summary from our Spring 2009 Research Workshop

The Spring 2009 workshop "MillionTreesNYC, Green Infrastructure, and Urban Ecology: Building a Research Agenda" brought together more than 100 researchers, practitioners and New York City policymakers to collaboratively develop a research agenda to support the management, practice and rationale for MillionTreesNYC and to contribute to the accumulating knowledge on the socio-ecology of urban landscapes and green infrastructure. The workshop was organized by the Research & Evaluation Subcommittee, a component of the MillionTreesNYC Advisory Board. Workshop activities included prepared presentations by NYC officials, USDA Forest Service scientists, and university researchers; site visits to a variety of MillionTreesNYC planting sites; and a two-day workshop consisting of dialog within and among discussion groups. The discussion groups were categorized into eleven topic areas:

  • Ecosystem Services: Local Air Quality and Urban Heat Island
  • Ecosystem Services: Water Quality, Storm Water Management
  • Economic Impacts: Quantifying Returns on Investment
  • Education
  • Human Health and Well-Being
  • Stewardship and Management
  • Green Jobs & Social Justice
  • Reforestation Dynamics and Forest Health
  • Biodiversity and Ecological Communities
  • Green Infrastructure
  • Implications of Scale

These eleven topics span an enormous range of intellectual and natural resources management activity and show how broadly the MillionTreesNYC campaign touches the population, the economy, institutions and built environment of New York City. The workshop is intended to be the first step in a broader process of integration between researchers and practitioners working to understand and improve New York’s environment and green infrastructure.
