Illinois Administrative Code › Title 17 - CONSERVATION › Part 1537 - FOREST MANAGEMENT PLAN › Section 1537.1 - Definitions

Current through Register Vol. 48, No. 28, July 12, 2024
"Advance Regeneration" - tree seedlings and saplings
				established and growing in the forest understory.
"Afforestation" - the establishment of forest trees by planting
				or seeding an area not previously forested.
"Basal Area" or "BA" - a measurement of the cross-sectional
				area of a tree, taken at breast height (41/2 ft.); a term commonly used as a
				measure of forest density and expressed in square ft./acre.
"Base Cost" - the estimated total cost of work for a practice
				based on the market.
"Cancel" - the act of an IDNR Forester cancelling a timber
				grower's Plan and enrollment in the Program due to:
sale of property;
failure to follow or implement required practices;
failure to adhere to 17 Ill. Adm. Code 1536; or
due to a timber grower performing or advocating any act or
				effort that damages, hinders or destroys forest land or forest resources in the
				FDA Program.
Cancellation removes a timber grower from the Program, thus
				preluding any benefits of the FDA Program, including preferential property tax
				assessment levels guaranteed by the program.
"Compatible Forestry Use" - lands not having productive forest,
				but that are permanent natural features or land uses that facilitate,
				compliment or enhance natural wildlife habitat, natural resource conservation
				or environmental or site quality, such as a rock outcropping, open wetland,
				natural grassland, firebreak, food plot or pond.
"Contiguous" - continuing without interruption by a nonforestry
				land use.
"DBH" or "Diameter at Breast Height" - the diameter of a tree's
				trunk measured at 41/2 feet above ground level on the uphill side.
"Desirable Species" - native or adapted forest trees, shrubs
				and herbs having desirable attributes as forest products and habitat.
"FDA" means the Illinois Forestry Development Act [ 525 ILCS 15
				].
"Flat Rate Payment" - a lump sum cost-share payment to a timber
				grower to cover a portion of the cost of a successfully completed practice,
				according to 17 Ill. Adm. Code 1536 and the Program Agreement.
"Forest" - a biological community whose dominant vegetation is
				trees.
"Forestry Best Management Practices" or "BMPs" - practical and
				economically achievable practices for preventing or reducing nonpoint source
				pollution.
"Forest Management Plan" or "Plan" - a written forest
				management planning document required of an entity entering the Program
				described in 17 Ill. Adm. Code 1536 and prepared, by a timber grower,
				professional forester or natural resource manager, to guide and direct the use
				and management of a forest property under the FDA, this Part (Section
				1537.60
				and Exhibit A, Section VIII) and 17 Ill. Adm. Code 1536. The Plan must be
				certified by the IDNR Forester.
"IDNR Forester" - an employee of the Department of Natural
				Resources, Division of Forest Resources, who is designated by position title as
				Forest Management Program Manager, Regional Forestry Administrator, Forestry
				Natural Resource Specialist or Natural Resource Advanced Specialist.
"Practice" - specific activities prescribed to be completed in
				an effort to improve or enhance the health, composition, quality, regeneration
				and growth of forests.
"Program" means the Forestry Development Cost-share Program
				authorized by the FDA and implemented at 17 Ill. Adm. Code 1536.
"Reforestation" - the re-establishment of forest cover by
				natural or artificial means on areas recently or historically supporting forest
				cover.
"Regeneration" - the renewal of a tree crop by natural seeding,
				sprouting, planting, harvesting or other methods; also includes young trees
				that will develop into the future forest.
"Silviculture" - the art, science and practice of establishing,
				tending and regenerating forest stands for the production of goods and
				services; the theory and practice of controlling forest establishment,
				composition and growth.
"Special Sites" - sites offering unique historical,
				archaeological, cultural, geological, biological or ecological
				characteristics.
"Stand" - a group of trees that, because of their similar age,
				condition, composition, management history and soil characteristics, are
				logically managed together as a single unit.
"Stocking" - a function of the number of trees, basal area and
				quadratic mean diameter per acre in a specific forest area compared to the
				optimal level to best achieve management objectives. Stocking may be expressed
				as a percentage or in relative terms such as understocked, fully stocked or
				overstocked.
"Timber" - trees, standing or felled, and parts of trees, that
				are capable of attaining a size and form that allows the trees to be sawn into
				usable lumber products, excluding Christmas tree plantations and woody crops
				raised primarily or exclusively for use as firewood or biomass.
"Timber Grower" - the owner, tenant or operator of land in this
				State who has an interest in, or is entitled to receive any part of the
				proceeds from, the sale of timber grown in this State and includes persons
				exercising authority to sell timber.
"Timber Stand Improvement" or "TSI" - a combination of
				intermediate cultural treatments designed to improve the growth, condition and
				composition of the forest.
"Treatment" - the act or effort of performing and successfully
				completing a practice or a combination of practices included in the
				Plan.
"Tree Shelter" - a constructed or commercially purchased
				shelter that is at least 4' in height designed to protect a tree from wildlife
				damage and/or enhance growth. Tree shelters must conform to 17 Ill. Adm. Code
				1536.65(c)(1).
"Wetlands" - those areas inundated or saturated by surface
				water or groundwater at a frequency and duration sufficient to support, and
				that under normal circumstances do support, a prevalence of vegetation
				typically adapted to life in saturated soil conditions.
