Legislative findings—1987 c 159: “Adequately funding construction of the state’s educational facilities represents one of the highest priority uses of state-owned lands. Many existing facilities need replacement and many additional facilities will be needed by the year 2000 to house students entering the educational system. The sale of timber from state-owned lands plays a key role in supporting the construction of school facilities. Currently and in the future, demands for school construction funds are expected to exceed available revenues.

The department of natural resources sells timber on a sustained yield basis. Since 1980, purchasers defaulted on sales contracts affecting over one billion one hundred million board feet of timber. Between 1981 and 1983, the department sold six hundred million board feet of timber less than the sustainable harvest level. As a consequence of the two actions, the department entered their 1984-1993 planning decade with a timber sale arrearage which could be sold without adversely affecting the continued productivity of the state-owned forests.” [ 1987 c 159 § 1.]
