As used in OAR chapter 629, divisions 605 through 669 and divisions 680 through 699, unless otherwise required by context:
(1) "Abandoned resource site" means a resource site that the State Forester determines is not active.
(2) "Active resource site" means a resource site that the State Forester determines has been used in the recent past by a listed species. 'Recent past' shall be identified for each species in administrative rule. Resource sites that are lost or rendered not viable by natural causes are not considered active.
(3) "Active roads" are roads currently being used or maintained for the purpose of removing commercial forest products.
(4) "Aquatic area" means the wetted area of streams, lakes and wetlands up to the high water level. Oxbows and side channels are included if they are part of the flow channel or contain fresh water ponds.
(5) "Artificial reforestation" means restocking a site by planting trees or through the manual or mechanical distribution of seeds.
(6) "Basal area" means the area of the cross-section of a tree stem derived from DBH.
(7) "Basal area credit" means the credit given towards meeting the live tree requirements within riparian management areas for placing material such as logs, rocks or rootwads in a stream, or conducting other enhancement activities such as side channel creation or grazing exclosures.
(8) "Bog" means a wetland that is characterized by the formation of peat soils and that supports specialized plant communities. A bog is a hydrologically closed system without flowing water. It is usually saturated, relatively acidic, and dominated by ground mosses, especially sphagnum. A bog may be forested or non-forested and is distinguished from a swamp and a marsh by the dominance of mosses and the presence of extensive peat deposits.
(9) "Channel" is a distinct bed or banks scoured by water which serves to confine water and that periodically or continually contains flowing water.
(10) "Chemicals" means and includes all classes of pesticides, such as herbicides, insecticides, rodenticides, fungicides, plant defoliants, plant desiccants, and plant regulators, as defined in ORS 634.006(8); fertilizers, as defined in 633.311; petroleum products used as carriers; and chemical application adjuvants, such as surfactants, drift control additives, anti-foam agents, wetting agents, and spreading agents.
(11) "Commercial" means of or pertaining to the exchange or buying and selling of commodities or services. This includes any activity undertaken with the intent of generating income or profit; any activity in which a landowner, operator or timber owner receives payment from a purchaser of forest products; any activity in which an operator or timber owner receives payment or barter from a landowner for services that require notification under OAR 629-605-0140; or any activity in which the landowner, operator, or timber owner barters or exchanges forest products for goods or services. This does not include firewood cutting or timber milling for personal use.
(12) "Completion of the operation" means harvest activities have been completed to the extent that the operation area will not be further disturbed by those activities.
(13) "Conflict" means resource site abandonment or reduced resource site productivity that the State Forester determines is a result of forest practices.
(14) "Debris torrent-prone streams" are designated by the State Forester to include channels and confining slopes that drain watersheds containing high landslide hazard locations that are of sufficient confinement and channel gradient to allow shallow, rapid landslide movement.
(15) "Department" means the Oregon Department of Forestry.
(16) "Diameter breast height" (DBH) means the diameter of a tree inclusive of the bark measured four and one-half feet above the ground on the uphill side of the tree.
(17) "Domestic water use" means the use of water for human consumption and other household human use.
(18) "Dying or recently dead tree" means a tree with less than ten percent live crown or a standing tree which is dead, but has a sound root system and has not lost its small limbs. Needles or leaves may still be attached to the tree.
(19) "Estuary" means a body of water semi-enclosed by land and connected with the open ocean within which saltwater is usually diluted by freshwater derived from the land. "Estuary" includes all estuarine waters, tidelands, tidal marshes, and submerged lands extending upstream to the head of tidewater. However, the Columbia River Estuary extends to the western edge of Puget Island.

(24) "Foraging area" means an area (usually a body of water) where bald eagles concentrate their hunting activities.
(25) "Foraging perch" means a tree or other structure that overlooks a portion of a foraging area and is habitually used by bald eagles as a vantage point while hunting.
(26) "Forestland" means land which is used for the growing and harvesting of forest tree species, regardless of how the land is zoned or taxed or how any state or local statutes, ordinances, rules or regulations are applied.
(27) “Forest practice” means any operation conducted on or pertaining to forestland, including but not limited to:

(29) "Free to grow" means the State Forester's determination that a tree or a stand of well distributed trees, of acceptable species and good form, has a high probability of remaining or becoming vigorous, healthy, and dominant over undesired competing vegetation. For the purpose of this definition, trees are considered well distributed if 80 percent or more of the portion of the operation area subject to the reforestation requirements of the rules contains at least the minimum per acre tree stocking required by the rules for the site and not more than ten percent contains less than one-half of the minimum per acre tree stocking required by the rules for the site.
