3 Original Inventory: Davey Resource Group, ,697 trees, stumps and sites 4,697 trees, stumps and sites 58 genera 110 species 58 genera 110 species Quercus comprised 25% of inventory, Acer 16% and Prunus 7.2% Quercus comprised 25% of inventory, Acer 16% and Prunus 7.2% 38% 6but 24 38% 6but trees Excellent, 2,197 Good, 1,570 Fair, 462 Poor, and 37 dead. 61 trees Excellent, 2,197 Good, 1,570 Fair, 462 Poor, and 37 dead. 157 recommended removals, 461 Hazard Reduction Pruning, 3,709 maintenance pruning 157 recommended removals, 461 Hazard Reduction Pruning, 3,709 maintenance pruning

4 Flat files and maps Street tree data in spreadsheet format Street tree data in spreadsheet format Web based forest management software Web based forest management software Work order forms Work order forms Reports available Reports available Finance tracking Finance tracking

5 Learning GIS Data Management Transforming flat file datasets to georeferenced GIS information can require negotiating several corners, but it can be done. After 6 years what was still good? What parcels were what? When 16 trees were on one lot? How can faulty data be used/corrected?

6 Parks and municipal property Tree in parks and undeveloped property were mapped using ESRI Tree in parks and undeveloped property were mapped using ESRI Included all city owned parcels excepting ROWs Included all city owned parcels excepting ROWs The same set of web based management tools were available for this set of trees. The same set of web based management tools were available for this set of trees.

7 Resources No field staff dedicated to tree care No field staff dedicated to tree care $110,000 budget for tree work $110,000 budget for tree work $10,000* plus various fees for planting $10,000* plus various fees for planting $15,000 for resource management $15,000 for resource management

8 Information requirements Existing trees Existing trees Existing tree spaces and limitations Existing tree spaces and limitations Utilized tree spaces Utilized tree spaces History of tree work History of tree work History of tree spaces History of tree spaces Requested tree work Requested tree work Requested tree installations Requested tree installations Special tree needs Special tree needs

9 Edited Data To make the data usable: Georeference Georeference Refer to spaces not trees Refer to spaces not trees Relate to tree data Relate to tree data Create additional data sets with history of trees including work or requests for service Create additional data sets with history of trees including work or requests for service
