Vulnerability

A System Already Under Stress

• Below ground

(e.g., soil volume, soil quality, utilities)

• At ground

(e.g., permeability)

• Above ground

(e.g., utilities, structures)

When properly planted and cared for:

• Long-lived urban trees generate

ecosystem services that increase

• ur resilience to climate change

If neglected, we risk:

• Disservices and increasing

emissions due to frequent tree removal and replacement

A System Already Under Stress

Risk and Vulnerability to Climate Change

Reduced growth and increased mortality due to… Reduced water availability and increased length of drought Waterlogging of soils and freshwater flooding Longer wildfire seasons and increased frequency and duration of wildfire More hot days that exceed species specific growth

• ptimums

More frequent and severe pest outbreaks and variety

• f pests

More salt-water inundation during storm surges Increasing diversity of species tolerant of Vancouver’s climate due to… Longer growing season, milder winters and fewer damaging frosts
