My experience with grazing reserves is you email then they send you an auto reply with the conditions and rules.

How to access PGRs
To enter any PGR, follow these 4 simple steps:
Locate the PGR on the AEP Recreational Access Internet Mapping Tool.
Email the PGR you wish to access. You will receive a confirmation email outlining the terms conditions for recreational access for that PGR.
Know the general recreational access conditions for the PGR you are entering.
Keep your confirmation email. It is suggested you retain this information, either on an electronic device or as a hard copy, when accessing the PGR. Failure to comply with the Recreational Access regulation and the terms and conditions of the access order may result in charges under the Recreational Access regulation.
