  Human impact
  Development
  From a regional perspective, the park is isolated from other natural areas because in Essex County, less than 6% of the native forest cover and 3% of the wetlands remain intact. Much of the area (97% of it) has been altered and mostly converted for agriculture, industry or urban development. It is also located relatively close to the major urban area of Windsor-Detroit.
