were either broadcast seeded or hy roseeded followed by 1 ton per acre of hydromulch
and 1000 pounds per acre of Biosol applied with a hydromulcher. Additionally,
approximately 4.5 acres of smaller areas not easily accessible by the hydroseeder were
hand seeded. These activities followed the reclamation techniques defined in the
Cresson Project Reclamation Plan.
