(a) Lands defined by ORS 273.251 as indemnity lands, school lands or farmlands.
(b) Lands which have escheated to the state.
(2) Nothing in ORS 273.805 to 273.825 is intended to be an express or implied limitation upon the powers of the department to acquire, lease, manage, control or protect land pursuant to authority otherwise granted by law. ORS 273.805 to 273.825 and 327.430 are not the result of a legislative intent or belief that the department is without authority to acquire, lease, manage, protect or control common school grazing lands.
