| Abstract: | In 2006, City of New York Department of Parks & Recreation launched a study to identify key factors influencing the mortality of its street tree population. With USFS and university project partners, Parks studied trees planted in diverse conditions (from concrete downtown to grassy outer boroughs) between 1999 and 2003. Using GIS, a 14,000 tree random sample stratified by time in-ground and land use was pulled from the original data set of 45,000 potential tree records. These trees were surveyed over the summers of 2006 and 2007. Field materials included tree attribute tables and a grid map series at 1:10,000. A survey tool was created with over 40 questions and was uploaded onto Palm Pilots for mobile data collection. Collected variables ranged from tree diameter and street width to the presence of stewardship or play equipment in order to examine social, biological and physical design factors. Spatial and non-spatial statistics are currently being applied to the collected data. Additional spatial analysis will be done in ArcGIS. Parks & Recreation will use the results to inform planting decisions and direct community outreach efforts. With the near endless diversity of neighborhoods surveyed, there is a broad target audience for this research. |
