Step 1:
Research the issue. Click on your assigned urban forest issue below.
Invasive Species
An invasive species is one that out-competes the native species in an area. Invasive species can be plants, animals, insects, or diseases; invasive species can be aquatic or terrestrial. You will be investigating how invasive species impact forests, urban forests specifically. There are many different invasive species impacting forests. Do not focus on a specific invasive species, but instead provide an overview of invasive species in general. (Another group will be investigating Emerald Ash Borer)

Tree Canopy Loss
The tree canopy is the area covered by the leaves and branches of trees. The word “canopy” can be used in terms of an individual tree or to describe the collective branches and leaves in an entire forest. Since the tree canopy has many benefits, loss of the canopy has many drawbacks.

Emerald Ash Borer
Emerald ash borer is an invasive insect species. This insect feeds on all species of ash trees. Since ash trees are common in Wisconsin’s urban forest, the potential impact of this invasive species is great.

Trees and Utilities
The companies that supply electricity to homes and businesses must maintain overhead power lines. Trees can grow into these lines and cause conflict.

Soil Compaction
Trees and other plants need soil to grow. Soil must have air spaces in it to let water percolate
through and must allow air to get to roots in order for the soil to support plant life. Soil that has been compacted has lost those air spaces. Soil Compaction Diagram

Heat Island
Concrete, asphalt, and other surfaces in urban areas absorb heat from the sun and re-radiate it. This creates what is known as a “heat island.” Urban areas tend to be 5-9 degrees warmer than surrounding rural areas because of this phenomenon.
