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
(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

means restocking a site by planting trees or through the manual or mechanical distribution
(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.
(20) "Exposure categories" are
used to designate the likelihood of persons being present in structures or on public
roads during periods when shallow, rapidly moving landslides may occur.
(21) "Filling" means the deposit
by artificial means of any materials, organic or inorganic.

at any time of the year by anadromous or game fish species or fish that are listed
as threatened or endangered species under the federal or state endangered species

used by young birds to develop flying skills.
(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.

(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

level established by rule of the board that represents adequate utilization of the
productivity of the site.
(33) “Harvest type 2”
means an operation that requires wildlife leave trees but does not require reforestation.

trees, per acre.
(34) “Harvest type 3”
means an operation that requires reforestation and requires wildlife leave trees.
This represents a level of stocking below which the size of operations is limited
under ORS 527.740 and 527.750.
(35) "High landslide hazard
location" means a specific site that is subject to initiation of a shallow, rapidly
moving landslide. The following criteria shall be used to identify high landslide

specified in (a) or (b) above, field identification of atypical conditions by a
geotechnical specialist may be used to develop site specific slope steepness thresholds
for any part of the state where the hazard is equivalent to (a) or (b) above. The
final determination of equivalent hazard shall be made by the State Forester.
