ORS § 390.980
In addition to State of Oregon funds available for the purposes of ORS 390.950 to 390.989 and 390.995 (2), the State Parks and Recreation Department may use such portion of moneys made available to it by any federal agency which may be used for such purposes, including matching funds, as the department determines are necessary or desirable to carry out the purposes of ORS 390.950 to 390.989 and 390.995 (2). In addition to the foregoing, the department may receive and may encourage the receipt of donated funds or property from individuals, groups or organizations (including trail users) for specified or nonspecified uses in connection with the acquisition, development, maintenance and administration of Oregon recreation trails. The department if it considers it advisable, may provide under its rules and regulations, for the use of a portion of any such donated funds received for nonspecified purposes to grant to an owner of private land adjacent to an Oregon recreation trail, funds indemnifying such owner for damage clearly caused to the land of the owner, and property therein, by users of such trail and which such landowner has not been able to recover from the user causing such damage.
