data sets were used to design planting specifications and the restoration program
for the Kankakee Sands project.
The restoration plans consisted of detailed hydrological, seeding and planting,
vegetation management, and soil preparation specifications for the entire 7,300
acres (Figure 9.10). A total of 5,200 acres of several key wetland types, 1,900
acres of various prairies, and about 200 acres of savanna were targeted in the
restoration plans.
A phasing program plan was prepared commensurate with financial resources
and labor and equipment availability to implement the program (Figure 9.11). The
initial stages of work involved collecting local genetic seed stocks from about a
thirty-five mile radius for approximately three hundred native plant species. Seeds
were dried and stored, and some percentage of supplies was direct seeded into
a 180 acre nursery established on-site and designed to provide enough pure live
native plant seed after year 3 to restore approximately one thousand acres of land.
A small fraction of seed was used for producing about two hundred thousand
plant plugs grown in the AES greenhouses that were also planted in the nursery
(Figure 9.12). A first-year planting of plugged New England aster (
Aster novae
angliae
) in the nursery during the first year produced over thirty pounds of pure
live seed per acre.
Disablement of tiles was done by simply backfilling ditches that were not encum-
bered by regulatory or legal protection. Using earthmoving equipment, filled-in

Restoration plans were completed by taking soils and their seed banks,
determining hydrological restoration potentials, and using reference natural areas for design
