Historic resources (archaeological sites and standing structures) are nonrenewable resources that enhance our understanding and appreciation of the cultural heritage of Illinois and possess information of federal, state, regional or local significance. It is the policy of the Department of Natural Resources (IDNR) to protect, preserve, conserve and interpret the historic resources present on lands owned and leased by IDNR

The CRMP secures historic resource evaluations for department undertakings in compliance with Federal and State historic preservation laws; informs department staff of research findings and recommendations; develops cultural resource management plans for department properties; nominates eligible sites to the National Register of Historic Places and develops policies and procedures for managing and protecting significant historic resources
