1. Selecting locations for Urban Tree Canopy

    A 2010 research paper titled: Prioritizing Preferable Locations for Increasing Urban Tree Canopy in New York City presents a set of Geographic Information System (GIS) methods for identifying and prioritizing tree planting sites in urban environments. It uses an analytical approach created by a University of Vermont service-learning class called “GIS Analysis of New York City’s Ecology” that was designed to provide research support to the MillionTreesNYC tree planting campaign. These methods prioritize tree planting sites based on need (whether or not trees can help address specific issues in the community) and suitability (biophysical constraints and planting partners? existing programmatic...
  2. Factors affecting young street tree mortality

    The U.S. Forest Service has released a publication called “Biological, social, and urban design factors affecting young street tree mortality in New York City.” Abstract: In dense metropolitan areas, there are many factors including traffic congestion, building development and social organizations that may impact the health of street trees. The focus of this study is to better understand how social, biological and urban design factors affect the mortality rates of newly planted street trees. Prior analyses of street trees planted by the New York City Department of Parks & Recreation between 1999 and 2003 (n=45,094) found 91.3% of those trees...
  3. Handicapping a key harbinger of spring

    Scientists at the US Forest Service’s Pacific Northwest Research Station Portland, Oregon, have developed a model to predict bud burst. They used Douglas firs in their experiments but also surveyed research on about 100 other species, so they expect to be able to adjust the model for other plants and trees. Both cold and warm temperatures affect the timing, and different combinations yield different outcomes — not always intuitive. With plenty of hours of cold temperatures, trees need fewer warm hours to burst. So earlier spring warmth will drive bud burst earlier. If a tree isn’t exposed to enough cold,...
  4. Woods to the Hoods

    The Urban Corps of San Diego County (UCSDC) is one of 17 organizations statewide selected to receive funding from the American Recovery and Reinvestment Act which is being administered by California ReLeaf. UCSDC’s mission is to provide job training and educational opportunities to young adults, in the fields of conservation, recycling, and community service which will assist these youths in becoming more employable, while protecting San Diego’s natural resources and instilling the importance of community involvement. The $167,000 grant for UCSDC’s Woods to the Hoods project will allow the Urban Corps to plant about 400 trees in three low-income, high-crime,...
  5. Vibrant Cities & Urban Forests Task Force

    The United States Department of Agriculture (USDA) Forest Service and New York Restoration Project (NYRP) are seeking nominations from the nation’s urban forestry and natural resource leaders to become part of the task force, Vibrant Cities and Urban Forests: A National Call to Action. The 24-member task force will draft a set of recommendations outlining a federal roadmap to meet the needs of cities committed to expanding, enhancing and stewarding their natural resources and urban forests. As they craft and advance the recommendations, task force members will apply their knowledge and experience to become high-profile champions of the nation’s urban...
  6. Plant a Tree, Rescue a Forest

    Plant A Tree, Rescue A Forest For Earth Day: Saturday April 17, 2010 Here is a unique chance to assist rangers with forest restoration after back to back forest fires throughout California. Volunteers will be planting seeds and performing seedling preparation activities at the US Forest Service Nursery in Placerville, CA. From these growing grounds young seedlings will be distributed throughout California’s national forests to areas of recent fires. Did You Notice? Air quality over the Bay Area has been significantly reduced during the summers of 2008 and 2009 due to fires in our forests resulting from numerous droughts, insect...
