The City has a target of increasing tree canopy coveracross the City to 18% by 2030. Currently the City has 12.9% average tree canopy cover across the City and over the last fouryears total canopy cover has hovered between 12.3-12.9%. Given that there is a margin of error of ±1%, it is difficult todetermine if there has been improvement or not on a City-wide scale.The City has a goal to protect trees in urban areas. For the past four years, the City has used High Resolution AirborneMultispectral Imagery to calculate changes to 'significant canopy'. 'Significant canopy' is defined as tree canopy cover thatis taller than three metres and has a larger area than 20m². Canopy loss is the result of the removal of trees from public andprivate land, as well as significant pruning.Unfortunately, significant canopy loss rates have increased over the four-year period. During this period, the City has lost acombined total of 808,000m² of tree canopy cover including 68% from residential land and 12% from the City's verges. In thissame period, Nollamara lost 11% of its tree canopy cover; Scarborough lost 10%; Balga lost 9%; and Doubleview and Innaloolost 8% of their tree canopy cover.In relation to development zones: over the four-year period, properties in the R40 zone had a net loss of 15% of their treecanopy cover and properties in the R30 zone and R25 zone lost 9% of their tree canopy cover. In relation to canopy growthacross the City: over the past four years, the City's existing canopy grew by 265,000m² but the chart shows that four years ofgain was effectively lost in one year (2015/16).Million Trees ProjectThe City aims to plant one million trees and shrubs over a 17-year period. Over the past seven years, the City's plantingaverage has been 55,448 trees and shrubs per year. In the 2015/16 planting season, the City is estimated to have planted71,000 trees and shrubs bringing its total planting numbers to 406,211.Tree Canopy Cover Target for 2030With a view to halting the loss of canopy cover, Council set a target of an average of 18% canopy cover across the City by 2030.
