<br />Davey Resource Group, Inc. <br />Tree Inventory Analysis & Maintenance Strategy <br />Appendix B <br />Study Area and Data Collection <br />Study Area <br />Orono covers an area of 25.15 square miles, of <br />which around 36% is bodies of water and the <br />remaining 64% is land. The city encompasses <br />three communities: Long Lake in the North, <br />Minnetonka Beach in the South, and Spring Park in <br />the Southwest. The 2019-2022 Orono inventory <br />focused data collection on all right of ways and <br />parks – it is DRG’s understanding that no data <br />collection was done in the wooded naturalized <br />areas of the city. All other spatial analyses (i.e., <br />i-Tree Canopy) were restricted to the same area as <br />inventory data collection. <br />DATA COLLECTION <br />DRG received an excel spreadsheet containing the inventoried tree data over a three-year time period. At each <br />site, the following data fields were collected by a contractor hired by the city of Orono: <br />● Address ● Condition <br />● Botanical Name ● Date <br />● Common Name ● Land Use/Park Name <br />● DSH* <br />Maintenance needs are based on Best Management Practices: Tree Risk Assessment (International Society of <br />Arboriculture 2011). The knowledge, experience, and professional judgment of DRG’s arborists ensure the high <br />quality of inventory data. <br />EQUIPMENT AND BASE MAPS <br />DRG received this data as an excel spreadsheet and the type of equipment used to collect the data is unknown. <br /> <br />Image 1.
