Colorado Revised Statutes Title 36. Natural Resources General § 36-1-129. Bonds

(2)(a) In leasing state lands for nonagricultural purposes, the state board of land commissioners shall require of the lessee a bond or damage deposit securing the state against loss of rents or other loss or waste, or occupation of the land for more than thirty days after the cancellation or expiration of the lease of the lessee, unless the lessee becomes the purchaser of the land, and the state board of land commissioners shall retain all interest earned on such a bond or damage deposit while held by the state board of land commissioners. In no case shall the lessee be allowed to cut or use more timber than is necessary for the improvement of the land or for fuel for the use of the family of the lessee; and the cutting and hauling of timber to sawmills, to be sawed on shares, is expressly prohibited.

(b) A lessee of state lands shall not be required to post a bond if such lessee is leasing state lands solely for agricultural purposes; except that a bond or damage deposit may be required for state-owned improvements even if leased solely for agricultural purposes.
