Expanding Urban Forests to Protect our Great Lakes

1000 Friends is leading a project to expand urban forest canopies to protect watersheds in four Green Tier Legacy Communities (GTLC). 

We are working with Ashland, Bayside, Oshkosh and Sheboygan to plant 350 trees to reduce runoff into the Great Lakes.

  • Ashland will be planting 30 trees, along with four rain gardens, native prairie plants and native shrubs in Bayview Park on the shore of Lake Superior to be the last line of defense against runoff.
  • Bayside (100 trees) and Oshkosh (120 trees) will be planting their trees on plots throughout their communities to help disperse runoff.
  • Sheboygan is replacing 93 ash trees that were removed because of the emerald ash borer (EAB) – they have identified locations that align with the City’s Storm Water Plan. The tree planting initiative also aligns with Sheboygan’s Emerald Ash Borer and Urban Forestry Plan the city adopted in 2016.

A grant through the USDA Forest Service Great Lakes Restoration Initiative (GLRI) is funding the tree plantings.

Urban forests are crucial green infrastructure tools for reducing storm-water runoff. The expanded urban canopies in the four communities will collectively take up a projected 20,650 gallons of water a year. The new urban trees will also help reduce pollutant and sediment loading into Lake Michigan and Lake Superior by mitigating erosion and increasing nutrient infiltration.

While urban forests are vital resources for natural storm-water management, they provide a number of other diverse community benefits:

  • Provide shade – mitigate the urban heat island effect
  • Lower energy demands
  • Reduce atmospheric CO2 levels and other air pollutants (see video below to learn how and why)
  • Reduce traffic speeds
  • Raise property values
  • Increase wildlife habitat

We are excited about this new land-use initiative and are expecting to lead similar projects across GTLC’s and other Wisconsin community’s in the future.
