Goal 1: Urban Canopy

about 1 year ago
CLOSED: This discussion has concluded.

The objective of the urban canopy is to increase the cover of the urban canopy to 20 per cent greater than the 2017 audit (see FAQs for heat maps of canopy). To achieve this, the following actions are proposed:

  1. Replace all deceased public trees in road reserves and public open space (public domain) as first priority
  2. Provide new street trees on demand as second priority
  3. Provide infill winter street tree planting to all road rehabilitation projects and EMP projects as third priority
  4. Ensure there is a nett increase in the number of public trees each year
  5. Maintain planting targets in greenway and bushland management plans

What are your thoughts on these actions?

    The objective refers to the '2017 audit'. Can the City please provide the statistics for this audit across the City, the breakdown for each suburb, land-use category, and land tenure, the method for achieving this audit, and the accuracy of the data within this audit? I agree with the comments below suggesting it is not always the best option to replace deceased public trees as they may provide important habitat. It is also important to consider how trees will be replaced when they are deceased. For example, the retention of stumps and roots may provide a source of inoculum of serious tree pathogens and exacerbate the issue that has caused the death of the specimen. More specifically:1. Replace all deceased public trees in road reserves and public open space (public domain) as first priority. Thoughts: I don't believe the replacement of such trees should be 'first priority' as stated. First priority should be to determine the cause(s) of death wherever possible and where it is not obvious, and implement measures to prevent repeated deaths of replanted specimens, and prevent spread of these cause(s) to nearby trees. 2. Provide new street trees on demand as second priority. Thoughts: It is only worthwhile providing new street trees on demand where these trees are of high quality. What procedures does the City have in place to ensure that supplied trees are of a high quality as in my experience the majority of trees supplied by nurseries in Perth are not. What will be the lead time from request for trees to supply? If a particular species is in short supply at a nursery then the only available stock may be of poor quality. How will the City deal with such issues?3. Ensure there is a nett increase in the number of public trees each year. Thoughts: This would suggest that the City has a detailed understanding of the total number of all of its public trees and a database that is regularly updated on loss and replacement of these trees to enable annual reporting of these statistics. Is this the case and what is the method for maintaining this database? Does the City have a good understanding of the annual change in the numbers of these trees over the past 5 years and if so what are the statistics? Is it realistic to expect the numbers to increase given the current trend? I don't necessarily agree that increasing the number of trees will enable an increase in canopy cover. For example, the replacement of one large tuart 30m in crown diameter with 3 smaller advanced nursery tuart 1m in crown diameter may never reach the same canopy area for many reasons. How will the City overcome such issues?

    Regarding street trees. Streets look more beautiful when trees are planted in "avenues" (same tree all along the road).There are some areas where there are many different species which makes the street scape unattractive.Is there some way of getting more continuity with street trees in streets that already have trees? eg choosing a species, removing others & replanting to make same?

    While I agree with the idea of planting new trees, I would caution against the plan to remove 'all deceased public trees' since these provide an important habitat for insect and bird life. It's not just about how trees look, it's about having a diverse, varied habitat for fauna which includes allowing trees to rot in their natural cycle so that animal life can benefit from this process. The aim is to support the entire ecosystem!
