Скачать или смотреть Urban Forests - saving our trees

Learn about how urban trees enhance our health and our suburbs with Melbourne Uni experts Dr Greg Moore and Judy Bush. Our local trees are under pressure, particularly from development and we need to take action now.

0:03 Intro to Dr Greg Moore OAM, Senior Research Associate, Melbourne Uni, Burnley Campus
0:25 Dr Greg Moore: What is an urban forest? Why 30% tree canopy - 3:30:300 rule
2:30 Urban tree lifespans are too short - conserving trees for best carbon and health results
5:52 Rising heat is really impacting our urban trees - getting serious about tree protection important given heat wave death potential
7:11 Tree distribution is much worse in Melbourne's disadvantaged North and West
8:18 Higher tree canopy associated with major health benefits including increased longevity, better student outcomes, maternal health, lower prescription drug use, and increased stress resilience
9:11 Loss of canopy due to over diligent powerlines clearances - could be 300mm like in South Australia in low bushfire risk areas

11:22 Intro to Dr Judy Bush, Senior Lecturer, Urban Planning, Melbourne Uni
11:51 Dr Judy Bush, big picture talk on how policy can protect urban trees
12:18 Policy: Urban forest strategy, local law, significant tree register and planning scheme provisions
12:36 Local laws and significant tree register criteria have considerable variation between municipalities
13:28 Planning scheme provisions include overall objectives and local provisions which vary between LGAs, for instance Boroondara does not use the overlay provisions as much as neighbouring LGAs
15:11 Particular provisions including tree retention, percentage of built area and permeability, but they are only triggered by a development application and require enforcement.
16:48 Policy integration - coordinating tree, health, climate and active transport policies, for instance for more shade on cycling lanes
18:13 Both individuals and governments may approve of tree positive policies, but still believe that it doesn't apply to them, for instance Grand Prix tree clearing.
18:54 It requires multiple policy approaches to protect and enhance our urban tree canopy and health benefits
