Generic Seed Mixes
    For The Hard Rock Program


Created by Pete Strazdas

This generic seed mix is recommended for hard rock and placer exploration and mine sites under Exploration or Small Miner Exclusion Statement provisions of the Hard Rock Mining Reclamation Act.  Operating Permit sites will have site-specific mixes.  Other agencies, such as the Bureau of Land Management, US Forest Service and Department of Natural Resources and Conservation, often recommend specific seed mixes for projects on land regulated by them.  Check with the particular agency for acceptability of Hard Rock Program Generic Seed Mix for reclamation on agency sites.
