Conn. Gen. Stat. § 12-102: Taxing of woodland.

The assessors of any town wherein woodland or land suitable for forest planting is situated, which the owner thereof seeks to have classified under the provisions of section 12-96, shall examine such land and give the owner thereof a sworn statement giving separately the value of the land and the value of the timber thereon. If such owner files written application with the assessors on or before September thirtieth in any year, such statement shall be furnished him on or before the first day of November following. Such land shall be placed in the list for such year at the value so placed upon it by the assessors, provided classification in accordance with the provisions of sections 12-96 to 12-100, inclusive, shall be granted by the State Forester prior to the completion and filing of such list by the assessors.
