Assessing the impact of vegetated curb cuts on temperature mitigation and biodiversity support in Trois-Rivières

Green infrastructure plays many roles in our cities

 

Vegetated curb cuts are designed for stormwater management

 

 

Vegetated curb cuts have the potential for co-benefits

Rue St Maurice as a case study

 

  • 54 curb cuts were installed in 2018
  • 20,000 plants were planted in 2018 and monitored for 3 years after
  • 7 different designs (+ controls)

What is the impact of vegetated curb cuts on different co-benefits?

  1. Temperature

  2. Pollinator (bee) interactions

  3. Vegetation management

Temperature is cooler in vegetated curb-cuts at night

Shrubs mediate night-time temperature

Design does not cause major differences in pollinator interactions

Trees and shrubs are most persistent vegetation

 

Vegetated curb cuts have benefits for human and non-human residents in cities

  • vegetated curb cuts have co-benefits
  • design of curb cuts impacts co-benefits
  • small scale green infrastructure affects night-time temperature (by many degrees!)
  • shrubs are providing cooling and mangement benefits

Thank you!
