Airboat: An airboat is a flat-bottomed watercraft that is propelled forward by an aircraft-type propeller and engine.Airboats are popular in Florida as transportation because they can easily navigate through shallow marshes, canals and lakes.  They are heavily used by Aquatic Weed Control to get into hard to reach areas.  The loud sound of an airboat is produced by the large propeller.

Alkaline soil:  This is soil with a pH level greater than 7.0 through most of the root zone or surface layer.

Annual Growth: the amount of new plant biomass produced per year, usually measured as above-ground production.

Annuals: plants which complete its life cycle in one year or growing season.  They quickly flower and produce seeds, and then wither. The success of this life form lies in the seeds, which often lie dormant until the next season.

Aquascaping:    The planting of plants to improve the appearance of a lake or pond using aquatic plants for environmental reasons.   This is often referred to as mitigation.

Aquatic Plant:  A plant that grows completely or partially in water.

Apron:  An area that protects the soil from soil erosion. This is like the sloped areas of concrete under a highway bridge or the sides of a dam or spillway.

Arbor Day:  Arbor Day is a nationally-celebrated observance that recognized the benefits of trees in the urban environment and encourages tree planting. Founded in 1872, National Arbor Day is celebrated each year on the last Friday in April.   Florida usually celebrates during the 3rd week of January.  Hundreds of communities do individual events and to find out the one in your area, check with your local city offices or county officials.

ATV: A small, open vehicle with one seat and large tires that is designed to travel over  a variety of  uneven, rugged terrain.   These are used by Aquatic Weed Control to get close to the waters edge in order to spray herbicides or to travel from pond to pond or carry light loads.

Carp Barrier:  In bodies of water with canals, spillways leading to other areas, carp barriers must be installed to prevent the grass carp from escaping.  Florida Fish and Wildlife require these before they will issue a permit to add carp to a waterway.  We custom build these barriers to fit the clients situation.

Category 1 exotic: The FLEPPC comes out with a list every 2 years.  Professional like Aquatic Weed Control, study these lists and adhere to the states regulations regarding these plants.  Category 1 exotics plants that cause ecological damage to native plant areas.   They  invade an area and quickly displace native plants.  There are currently 67 plants on this list.  The best thing a land owner can do to help the State of Florida in controlling these plants is not to introduce them into your landscape.    Some well-known plants are; Camphor tree, water-hyacinth, hydrilla, cogan grass, Melaluca tree, torpedo grass, water-lettuce and Brazilian Pepper tree.

Category 2 exotic:  There are 71 plants on this list.  They are spreading and increasing in area but they have not caused ecological damage, yet.  We can help landowners identify and remove these plants from the property before their exotic seeds are spread by the wind,  wild by birds and animals.  Some of the more well-known plants on this list are; alligator weed, was begonia, bamboo, Lead tree, Chinaberry, papyrus, Sesbania, and caster beans.

Certificate of Insurance:  A certificate of insurance is issued by an insurance company/broker that is used to verify the existence of insurance coverage under specific conditions granted to listed individuals. More specifically, the document lists the effective date of the policy, the type of insurance coverage purchased, and the types and dollar amount of applicable liability.   Certificates are issued to customers of Aquatic Weed Control.

Degradation:  To wear away an area by erosion.  An area where large amounts of water have degraded the banks of a waterway.

Detention:   This is a pond or area that temporarily store runoff water prior to it's gradual release into a creek, retention pond, etc.

Disturbance: Any event which alters or stresses an environment’s structure and function.

Dormant:  A state where a plant in a suspended state of growth.   This time is needed  to protect the plant from bad weather conditions so that it can resume growth when the weather improves.

Drain:  Is the action of moving excess water down or away.  The water can move through ditches, pipes, channels or percolate through the soil. 

Dredging: use of motorized piece of equipment to clean, deepen, or widen a waterway to improve navigation and/or control aquatic weeds.

Duck box:   These boxes are built for nesting purposes around lakes, ponds and marshes throughout the state are potential production sites for wood ducks.  We recommend that all wood duck boxes be erected over water, using steel or wooden posts with predator-proof metal cones or sleeves. Wood ducks nest from mid-February to mid-March.  Cedar is a natural favorite for box construction because it is naturally resistant to weather and insects. A little latticework inside the front of each box acts as a ladder for the chicks to climb out.  At the end of nesting season the boxes need to be cleaned of the old nesting materials and replace it with a fresh layer of wood shavings. This annual cleaning is a necessary part of long-term maintenance of your duck boxes.   Although these nesting boxes are intended primarily for wood ducks, other species of wildlife will also find them attractive for homes. Other visitors could be owls, woodpeckers and the occasional honeybee.

E

Ecological Restoration: altering an area in such a way as to reestablish an ecosystem’s structure and function.  The goal is to bring it back as close to its original state or to a healthy state.

Ecosystem: a collection of interacting organisms and their physical environment that functions together as a single area unit.

Emersed: are aquatic plants that have their roots in sediment with the plant’s leaves and flowers showing above the waterline.  Torpedo grass, maidencane and cattails are examples of emersed plants that usually grow near the bank and can extend out 3 to 10 feet.

Enzyme:   A chemical that breaks down a substance/matter or allows a chemical reaction to occur.

Erosion: Erosion can be a real problem during heavy rains when the water pours into waterways and cause the bank to erode.  It depletes the surface soil or rock edges and cause them to crack and fall into the water.

Erosion Blanket:   These blankets consist of degradable natural threads like hemp or coconut fibers that are pinned in place along shorelines.  They are designed to provide protection and promote vegetation establishment in 45 days to 12 months, depending on the blanket and plants used.  New vegetation is planted throughout the blanketed area.  The blanket holds the shoreline and slowly degrades as the new plants take root and control the area on their own.

Eutrophic: refers to a body of water which is excessively rich in dissolved nutrients and usually poor in dissolved oxygen.

Evolve: proceeding through the natural process of change caused by genetic mutations and selection upon those mutations for environmentally favorable traits. Two different environments can lead to the evolution of two different organisms from one ancestor.

They are designed for digging and moving earth. They dig with hydraulically powered arms that are used to dig ditches, move materials, heavy lifting, waterway dredging, general grading and more.  With the proper attachment they can be used to cut trees and brushes. Their design came as a natural improvement to the steam shovel.

Exotic plant:   As European explorers traveled to th shores of Florida, they brought with them nearly 1,300 exotic plants which are reproducing on their own in the wild or a with help from humans. These problem plants are considered "invasive"   When they were removed from their native lands that has controls in place like climate, diseases or insect pests to control them and were transplanted to Florida they became very aggressive just to survive. They grow very fast and take over any and all Florida's native species. The Florida Department of Environmental Protection publishes a list of unwanted plants every 2 years.

F

Fertilizer:  This is a matter that is added to the soil or plant to stimulate plant growth.  Most often the aquatic technicians see fertilized grass clipping floating in ponds which puts nutrients in the water and encourages algae and weed growth. Make sure to instruct landscapers to blow clippings away from the water.

Filtration: removal of particulate matter from water due to obstruction and reduced water velocity.

Floating Mats:  These are plants that have roots under the water or no roots at all.  Their their leaves or stems grow into mats that float on the surface of the water.   Some of these plants are algae, water hyacinth and salvinia.

Moveable Dam:  A barrier that can be moved in a way to allow a small or large opening to permit water to flow in a controlled way through or over a dam.

Muck: a highly organic, dark or black soil.  This is rotten vegetation that builds up over time and decreases the capacity of a waterway.  The act of taking out the muck is called demucking. There are two general kinds of soils—mineral and the organic type called muck or peat.   Muck fires can cause problems for neighborhoods   and firefighters for months. They can heat to 500 degrees, smolder as deep as the muck goes, burn for weeks and rekindle forest fires long after they are thought to be gone.  Sizzling organic muck can transfer enough underground heat sideways to spark forest fires several yards from the original fire, even after the main fire is out.

Mulch:  A natural or artificial layer of plant materials, such a tree bark, tree mulch, sand or paper to cover the soil surface.

N

Native Plants:   Native plants are those that grow naturally in a particular area and were doing so before humans introduced plants from other countries to the area.  Any plant that was in Florida before Columbus is considered a Native.  Native plants in Florida glow in harmony together native plants.  We at Aquatic Weed Control has our own Native Plant Nursery where we grow plants to supply out client's needs. 

Naturalized: Refers to a previously exotic or foreign species which has established in and conformed to an ecosystem.

Niche:  A specific area where the environmental conditions allow a specific plant or tree to thrive.  They have found their niche.

Non-native:  Any plant that was brought to Florida from another country is considered a non-native.  Thousands were brought over by early settlers in the 1800's.  Of the nearly 1,000 non-native plants in Florida over 100 are invading natural areas and cause environmental problems.  About 30 of these plants are so bad that millions are spent every year to try to keep them under control.

Nuisance plants:  As early travelers from other countries came to the shores of Florida, they brought with them over 1,300 exotic plants which are reproducing on their own in the wild or a with help from humans.   These problem plants are considered "invasive"   When they were removed from their native lands that had controls in place like climate, diseases or insect pests to control them and were transplanted to Florida they became very aggressive just to survive.  They grow very fast and take over any and all Florida's native species.  The Florida Department of Environmental Protection publishes a list of unwanted plants every 2 years.  Some native plants can also be nuisance plants, like Cattails.

Nursery: This is a place where plants are propagated and grown to a usable size.  We at Aquatic Weed Control have our own Native Plant nursery where we grow our own plants and pass the savings onto our customers.

Nutrients: chemical compounds in a usable form for plants and/or animals. Example would be phosphate and nitrogen.

O

Oligotrophic: refers to a body of water that is very low in minerals and is poor in dissolved nutrients and usually rich in dissolved oxygen.

Open Drain:  The path in which water drains created naturally or constructed.

Organic Matter:  Any material or organism alive or dead.

Outflow:  An area where water can flow through a drain, ditch or pipe.

Oxygen levels:  The level of oxygen in a body of water is important if your pond is stocked with fish.  As dissolved oxygen levels in water drop below 5.0 mg/l, fish are put under stress. The lower the concentration, the more the stress on the fish.  Oxygen levels that remain below 1-2 mg/l for a few hours can result in large fish kills.   This can often happen during a Florida winter when the water levels are low and the water temperatures are cold.

The level of dissolved oxygen in a body of water can vary from hour to hour. The level falls as fish remove oxygen molecules from the water with their gills. The more fish in the water, the more dissolved oxygen they remove. That is why AWC uses a formula to determine how many Tripoid Grass Carp are needed in a body of water. 

Pond managers can improve oxygen in small ponds by using aerators. It is usually difficult, however, to increase oxygen levels in ponds larger than 2 or 3 acres.

Pigment:  a matter that makes a plant have a distinctive coloring; may have protective properties or attraction properties like in the spatterdock or a Venus Fly Trap.

Petiole:  The connecting piece from a leaf or flower to a plant stalk.  When flowers are pinched off to promote growth, it is often recommended to pinch it off in this location. 

Predation:  refers to consumption of an organism, the prey, by another organism, the predator.  The Bladderwort plant captures very tiny invertebrates in their bladders that are attached to stems. Prey brush against the tiny hairs connected to the bladder’s trapdoor.

Propagation:  the act of creative new plants, multiplication by natural reproduction or vegetative means; ei, seeds, bleeding, grafting, etc.

Propagule: Any part of a plant that can give make a new plant that aids in a plant spreading. The tubers of the pickerel and water lilies plant are good examples.  They spread along the bottom of a waterway and send up new shoots that will reach above the waterline.

Random: 1.) having an undefined distribution (not clumped and not uniform). 2.) having a likelihood of being selected that is not biased from any other item in the selectable area.

Raking:   This is a service we can provide to customers with beaches on the lakefronts.  Regularly raking the sand takes off all organic material that would otherwise decompose and turn to muck. 
Waterways in Florida often get spikerush, hydrilla and eel grass mats that form on the surface.  Our team uses specialized rakes to rake out the mats and then haul the debris away.  This is followed up by a maintenance program to keep them from coming back.      

Reclamation: The process of changing an area to bring it to a healthy state unlike the original ecosystem.

Rehabilitation:  Changing a deteriorating habitat in order to improve ecological function.

S

Sandy soil: Sand is sedimentary grains 2 -1/16 mm in diameter.  Sandy soils have a gritty texture and are formed from weathered rocks such as limestone, quartz, granite, and shale. If sandy soil contains enough organic matter it is easy to cultivate, however it is prone to over-draining and summer dehydration, and in wet weather it can have problems retaining moisture and nutrients.

Savanna: tropical grassland region with scattered trees or shrubs.

Sediment:  Is a solid material that has been moved from it's original area by water, gravity, air, wind as a byproduct of erosion.

Sedimentation: settling of particulate matter in water related to particle size, water velocity, and water flow.

Silt: sedimentary grains smaller than sand. Silt can be found at the bottom of bodies of water where it accumulates slowly by settling through the water.

Skiff: A flat bottom open boat of shallow draft, having a pointed bow and a square stern and propelled by oars, sail, or motor.  Skiffs are usually manned by one person and are used by Aquatic Weed Control to provide service in open waterways.  They are light and can be unloaded and loaded back onto a trailer by one person.

Soil Horizon: layer of soil developed in response to localized chemical and physical processes resulting from the activities of soil organisms, addition of organic matter, precipitation, and water percolation through the layer.

Spodosol: type of soil layer with precipitated (solid) organic matter, aluminum, and iron.

Submersed:  Refers to a plant that has growth mostly or entirely underwater. Hydrilla and eel grass are submersed plants.

Sustained yield: perpetual achievement and maintenance of a high level of annual (or regular periodic) output of the various renewable resources of the public lands.

Swamp devil:  Refers to powerful vegetation. It is the ultimate weapon in annihilating heavily matted vegetation that cannot be controlled using conventional harvesting equipment. The Swamp Devil is designed for use in areas where dense aquatic vegetation is clogging waterways, restricting water flow and impeding boating and navigation.

T

Terrace:  A nearly level strip of land with one or more levels rising one above the other.  This is sometimes used to control erosion by changing the runoff channel of water that would have allowed it to flow uninterrupted down from the soil.

Topographic:  Refers a detailed mapping or charting of the surface of a small area or district.  Elevations are shown, surface configuration by means of surveying.

Topped -out:  An action in which submersed plants reach the water's surface and form mats that reduce the amount of sunlight and oxygen.  Hydrilla is one of these plants.

Topsoil: the surface layer of soil that has favorable characteristics, which are usually high in nutrients which makes it good for plant growth,

Track Hoe:  A machine also known as an excavator.  They have a bucket, a boom and a cab  where the person sits to operate the machine.  They may run on wheels or by laying tracks. They are designed for digging and moving earth. They dig with hydraulically powered arms     that are used to dig ditches, move materials, heavy lifting, waterway dredging, general grading and more.  With the proper attachment they can be used to cut trees and brushes. Their design came as a natural improvement to the steam shovel.

Triploid Grass Carp:  These are carp that are bread with 3 sets of chromosomes which makes them sterile and unable to reproduce in the wild.  These are the types of fish we supply to our clients to control weeds in difficult waterways because they love to eat.

Turbidity: Refers to water that is not clear, cloudy, contains some amounts of sediment  suspended in water.  This can occur when working along shoreline and the earth is displaced as part of the work.  The law requires that Turbidity Barriers be installed to prevent this type of water and debris from getting into an otherwise clean waterway.

Turbidity Barrier:   These are designed to keep silt, sediment and debris from migrating off the job site into water and are required by State and Federal regulations.   When the unwanted vegetation is cleared the barrier will be pulled to the shore and the debris is caught in the barrier and taken away to reveal a clean area.

Tussocks and floating islands:   These are islands that sometime appear in waterways.  They are usually made of native plants.  The islands can range from a few feet wide to acres and sometimes trees will take root and grow on them.  Animals can actually live on these islands like alligators, ducks and birds. Aquatic managers refer to these floating islands or forests as tussocks. Water levels can be controlled with through levees and dams which help to suppress tussocks formation.
