DENVER -- Referendum M is one of two items on the November ballot dealing with obsolete provisions in the state Constitution.

“Every election cycle we tend to do some provision that gets rid of obsolete provisions in our constitution,” Assistant House Majority Leader Terrance Carroll told 7News. “In this case, it’s about land value and land increases.”

Referendum M would remove the wording in Colorado’s Constitution regarding tax exemption for property owners who plant forests on private land.

“Much of the work we do about land values and increases in land value is actually done on the county level through county assessors and it's really out of the hands of the state," said Carroll.

Opponents of the referendum say removing the measure could end up limiting the power of the state legislature to provide a tax exemption for planting trees on private land.

Supporters say since it’s an issue each county takes care of, there’s no need for it to be in the Constitution.

“These provisions in the constitution go back into an era in the state when the state was first founded," Carroll said. "We really just don't need them anymore."
