Maintenance and restoration of natural areas and woodland habitats in Northern Illinois

The Morton Arboretum is the site of numerous restoration projects. This includes the restoration of a 40 hectare tallgrass prairie and savanna which is one of the oldest tallgrass restoration projects in the United States. The Schulenberg Prairie and Savanna was established in 1962 and has developed over the decades to include over 500 plant species, including the introduction of 9 endangered species. The propagule sources for this restoration all came from within 80 kilometres of the restoration site, many of which have been subsequently demolished due to development and urban sprawl. The high species richness of this restoration also ranks similarly to local prairie remnants, a feat which is incredibly difficult to attain in tallgrass prairie restorations.

Oak Savanna woodland

The Morton Arboretum is also restoring 280 hectares of oak woodland, known as East Woods, which contains an old second growth oak (Quercus alba, Q. rubra, Q. ellipsoidalis, Q. macrocarpa) canopy with a greater sapling layer presence of mixed mesophytic species. This restoration includes experimental methods of prescribed fire and canopy thinning to recruit oak seedlings, which are largely absent from the woodland. Current management activities have yielded significant increases in species richness, including two locally threatened plant species. Finally, overall habitat heterogeneity throughout the Arboretum’s natural areas has recently fostered more ecological restoration projects within wetlands and along 6 kilometres of streams.
