112 S i l v i c u l t u r e Best Management Practices

Basal Area Forestry term used to refer to the 

density of a stand of trees, expressed in square 

feet/acre. On a per tree basis, the basal area 

is the cross-sectional area of the tree at breast 

height.

Bedding A technique whereby a small continuous

ridge of surface soil is formed to provide an 

elevated planting area or seed bed. In Florida, 

it is used primarily on wet sites to improve soil 

drainage and aeration for seedlings.

Borrow Pit An excavation site to provide fill 

material necessary for forestry related activities 

such as road construction.

Broad-Base Dip A reversal in the grade of 

a permanent access road for the purpose of 

intercepting and diverting surface water flow 

without seriously impeding vehicular traffic.

Cavity Tree (Den Tree) Mature hardwood and 

softwood trees that are hollow and typically of 

the older age classes that are used by certain 

birds and other small wildlife species for shelter 

and habitat.

Canal A man-made waterbody; does not include 

natural streams that have been modified by 

dredging or straightening.

Chopping A mechanical treatment whereby 

vegetation is chopped by blades on a roller drum 

implement, pulled by tracked or rubber tired 

equipment. The “chopping’’ of this vegetation 

facilitates: more control of prescribed burning, 

decreases rough vegetation conditions, provides 

some level of control on competing vegetation, 

improves tree planting conditions.

Class I Waters Waterbodies that serve as 

sources of potable water supply; designated 

by the State for additional water quality 

protection.

Clearcutting A silvicultural system in which 

all merchantable timber is harvested within a 

specified area in one operation.

Cross Ditch A shallow depression built 

diagonally across a road or trail for the 

purpose of diverting water off the road surface.

Cross-Drain Culvert A metal, wooden, plastic or 

concrete conduit through which surface water 

runoff is directed underneath the road surface 

to the opposite side.

Detritus Natural woody debris such as leaves, 

branches, etc., provided by trees – serves as a 

food source for certain aquatic insects.

Ditch Plug Material used to partially or 

completely obstruct the flow of water in a ditch.

Erodible Soils Those soils identified as being 

subject to erosion based on soil texture, 

composition and topography.

Erosion The process by which soil particles are 

detached and transported by water, wind or 

gravity to some down slope.

Fertilizers Any substance or combination of 

substances used primarily as a source of plant 

nutrition or soil amendment.

Firelines Constructed barriers typically 

established by plowing and/or harrowing to 

contain fires within a specific area.

G l o s s a r y
S i l v i c u l t u r e Best Management Practices 113

Flowing Wetland A wetland (listed in appendix 5)

that has a surface connection to a well defined 

stream channel at one or more points, and has 

a definite stormwater inflow and/or outflow.

Foam Line Type of fireline that incorporates 

the use of fire-resistant foam material in lieu 

of, or in addition to, plowing or harrowing.

Low Water Hard Surface Crossings (Fords) 

Rock, brick, logs, and other stable materials 

place on the bottom of certain perennial or 

intermittent stream channels to accommodate 

traffic during periods of low water flow.

Harrowing (Disking) A mechanical means of 

scarifying the soil to reduce competing vegetation 

and to prepare a site to be seeded or used as a 

fire break.

Harvest Unit Refers to an area of specific size 

and location where timber harvesting operations 

are being performed.

Haul (Spur) Roads Temporary forest roads 

constructed to facilitate the transport of timber 

or other forestry related activities.

Hydric Soils Soils exhibiting a considerably wet 

nature, typically characterized by a dark color 

and associated with wetlands.

Hydrology The scientific study of the properties, 

distribution and effect of water on the earth’s 

surface, in the soil and underlying rocks and in 

the atmosphere.

Hydroperiod Period of time during which soils, 

waterbodies, and sites are saturated.

Impoundment Areas Those areas within which 

water is stored by artificial means such as a 

dike or dam.

Intermittent Stream A stream that has a well 

defined channel but maintains only seasonal 

flow under typical climatic conditions.

K-Factor An index representing the potential 

erodibility of a soil, by water, based on soil 

texture.

Leave Trees Large mast producing and/or 

cavity trees which are representative of the 

older age classes of the stand and are considered 

valuable for wildlife, or related ecological 

purposes.

Logging Debris The unused and generally 

unmarketable accumulation of woody material, 

such as limbs, tops, cull logs and stumps, that 

remain as residue after timber harvesting.

Mast-Producing Trees Various species of trees 

considered valuable for the production of food 

for wildlife.

Mat Logging Sometimes referred to as “shovel 

logging” - a technique used on wet sites where 

logs are temporarily placed in skid trails, 

creating a log “mat” upon which the skidders 

operate.

Modified Stream A natural watercourse which 

has been dredged or straightened.

Non-Point Source (NPS) Water pollution which 

is not traceable to any discrete or identifiable 

source, but rather is generated by activities 

within a diffuse treatment area.
114 S i l v i c u l t u r e Best Management Practices

OFWs Outstanding Florida Waters Waterbodies 

which exhibit unique characters in terms of 

quality and value designated by the State for 

additional protection from further pollution 

and degradation.

ONRWs Outstanding National Resource Waters 

Waterbodies which exhibit characteristics 

that meet specific water quality standards for 

national designation for protection from 

pollution and degradation.

Operational Application Method by which 

pesticides and fertilizer are applied, using 

commercial type equipment such as skidders 

or tractors and large boom equipment. Does 

not refer to hand-held spreaders or small scale 

equipment (4-wheelers).

Perennial Streams A watercourse that flows 

in a well-defined channel throughout the year 

under typical climatic conditions.

Pesticides Chemical substances, either liquid 

or granular, that are used for the control or 

eradication of undesirable insects, diseases, 

vegetation, animals and other organisms. 

Herbicides, Insecticides, Fungicides and 

Nematicides are all considered pesticides.

Pollutants Natural or man-made waste material 

that contaminates air, soil or water.

owned and managed by any unit of local, 

regional, state or federal government. Lands 

not wholly owned (i.e., lease, wildlife management 

agreement, easement, life estate, purchase 

agreement, etc.) may limit the terms of control 

by a unit of government.

Raking Component of site preparation in 

which non-merchantable trees, some stumps, 

roots, and logging slash are piled and/or 

pushed into individual piles or windrows by 

heavy equipment with rake-like blades. 

Refuse Inorganic waste materials such as 

metal, rubber, plastic and glass.

Regeneration The young tree crop that either 

artificially (machine/hand planting) or naturally 

follows a stand of older trees.

Rip-rap Aggregate material placed on potentially

erodible sites to reduce the impact of rain or 

surface runoff from these areas.

Rotation The period of time required to 

establish, grow, and harvest a crop of trees at 

a specified stage of maturity.

Sediment Soil particles which have been 

detached and transported by water during the 

process of erosion.

Seed Tree Cut Method of timber harvesting 

that provides for the natural regeneration of 

a site by leaving single, or small groups of 

seed-bearing trees distributed throughout the 

harvest area.

Selection Cut Removal of select trees within 

a forest stand based on some economic or 

physiological criteria. Generally results in 

uneven aged stands.

Shelterwood Cut Removal of mature timber 

within a forest stand in a series of harvests 

which extend over a relatively short portion 

of the rotation in order to encourage the 

establishment of even-aged reproduction under 

the partial shelter of seed trees.
