The point dataset was obtained by WCA from WCA in Oct 2021. The attributes of interest to this study included unique TreeID, Exact DBH, DBH Range, Height Range, Botanical Name, Common Name, Latitude, and Longitude. Updates to the tree layer were made by joining the results from the Oct 2021 i-Tree report. An i-Tree Eco Analysis was run in Oct 2021 using i-Tree Eco v6.0.22 and the results were joined based on unique tree ID to the Tempe’s tree inventory. <span style='font-family:inherit;'> </span>Attributes added were: Structural Value ($), Carbon Storage (lb), Carbon Storage ($), Gross Carbon Sequestration (lb/yr), Gross Carbon Sequestration ($/yr), Avoided Runoff (cubicFT/yr), Avoided Runoff ($/yr), Pollution Removal (oz/yr), Pollution Removal ($/yr), Total Annual Benefits ($/yr), Height (ft), Canopy Cover (sqft), Tree Condition, Leaf Area (sqft), Leaf Biomass (lb), Leaf Area Index Basal Area (sqft), Cond, i-Tree_ID_BotName, i-Tree_ID_ComName and i-Tree_ID Genus. The exact definitions, meanings, calculations, etc. for the i-Tree Values can be found on i-Tree’s website via the i-Tree Eco User Manual. For certain layers the individual i-Tree values were aggregated by census tract, census block, zip code, etc. These results can be seen in the polygon layers with the following attribute values: CanopyCoverPer_Final, COUNT_Tree_ID, SUM_Replacement_Value____, SUM_Carbon_Storage__lb_, SUM_Carbon_Storage____, SUM_Gross_Carbon_Sequestration__lb_, SUM_Gross_Carbon_Sequestration____y, SUM_Avoided_Runoff__ftÂ__yr_, SUM_Avoided_Runoff____yr_, SUM_Pollution_Removal__oz_yr_, SUM_Pollution_Removal____yr_, and SUM_Total_Annual_Benefits____yr_</span></p><p style='margin-top:0px; margin-bottom:0in; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial; font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'><span style='font-family:&quot;Segoe UI&quot;, sans-serif; font-size:10pt; border:1pt none windowtext; padding:0in;'><br /></span></p><p style='margin-top:0px; margin-bottom:0in; background-image:initial; background-position:initial; background-size:initial; background-repeat:initial; background-attachment:initial; background-origin:initial; background-clip:initial;'><span style='border:1pt none windowtext; padding:0in;'><font face='Segoe UI, sans-serif'><span style='font-size:13.3333px;'>This dataset also contains the Tree Equity Score from American Forests. The Tree Equity Score is a product of American Forests and is a metric that helps cities assess how well they are delivering equitable tree canopy cover to all residents. The score combines measures of tree canopy cover need and priority for trees in urban neighborhoods. It is derived from tree canopy cover, climate, demographic and socioeconomic data.
