Naturalization has many benefits.

Naturalization is the process of encouraging altered or degraded lands that may possess little habitat or ecological value to regenerate into a natural state.

There are many benefits to naturalization including:

  • Increasing our urban tree canopy
  • Protecting fragile river valleys
  • Creating or enhancing wildlife corridors and habitats
  • Creating forest edge buffers

Natural areas support species at risk, improve air and water quality, increase natural cover and buffers, and in some instances, reduce noise levels. Naturalization reduces the speed of water and soil erosion and eliminates dangerous parkland maintenance sites such as slopes. These valuable areas naturally increase public awareness and foster an appreciation of nature.

Woodland Management
The City of Mississauga manages and maintains over 130 woodland areas. When trees are pruned or removed, all limb and trunk wood is left on site within the wooded area. By leaving all material on site, we do not disturb or affect the sensitive regeneration of native flora and fauna and encourage natural regeneration by providing materials for regrowth and habitat for woodland insects and animals.

Natural Area Enhancement & Restoration
The Parks & Forestry Division have been enhancing natural areas in City parks and green spaces for over 40 years. This work is mainly done through a process called naturalization where altered or degraded lands that may possess little habitat or ecological value are encouraged to regenerate into a more natural state consisting of trees, shrubs and ground cover. With the support of volunteers, tens of thousands of trees, shrubs, wildflowers and grasses are planted annually through this program.
