COMPREHENSIVE FINAL EXAMINATION ACADEMIC YEAR: 2025/2026
Name users and their associated uses of water resources in VA
1. Public utilities: provide drinking water
2. Campgrounds, parks, etc: recreation
3. Owners of waterfront property manage their water: protect their investment
4. Industry depends on cooling and fire ponds for safety
5. Irrigation districts provide water for crops and livestock
6. Real estate developers, streams, and lakes provide aesthetic appeal
7 Fish farmers use aquatic systems for the commercial production of fish
What necessary and beneficial roles do aquatic plants play in their native systems?
Serve as food, habitat, and shelter for other aquatic organisms. Stabilize the substrate, filter
storm and runoff water

,When do aquatic plants become a problem?
In large numbers, aquatic plants can hamper fishing, swimming, and boating. Plant masses can
also adversely affect the chemistry of underlying waters, degrading fisheries and killing food
supplies for fish
Name the six weed control option that this manual will discuss
Prevention and cultural, manual, biological, mechanical, and chemical control
Which of the six control methods should often be your first line of attack
Prevention
Name several things you must consider when making weed management decisions
1. Type of plant
2. The use of the water
3. Physical constraints
4. Water quality
5. The impact your control tactic will have on fish and wildlife
List four aquatic pests not addressed in this manual: Explain why they are not covered:
1. Mollusks: Catagory 5B Marine antifoulant paints
2. Mosquitos and black flies: Catagory 8 public health and pest control
3. Nusiance reptiles, amphibians, and leeches: no chemicals currently used
4. Nuisance mammals and birds: Catagory 7D Vertebrate pest control

,Why is it important that aquatic weed managers learn good communication skills
Weed managers are often the most visible members of an aquatic resources team. They are
often seen and remembered by the public. Weed managers may need to respond to an on-the-
scene reporter or inform residents about what technique or chemical is being applied and why.
Well prepared weed managers are critical in a public relations program.
Explain why notifying landowners before implementing a control program is especially
important
Early notification enables you to meet and discuss the control program with nearby landowners
before application begins. Details about how, where, and when you will be working can be
discussed. Areas of special concern can be addressed in advance.
When approached by a landowner concerned about the weed control method you are
performing, how should you proceed?
Be polite and businesslike regardless of what they say or do. Answer questions honestly.
Aquaculture-
The cultivation of fish, plants, and other aquatic products for sale
Aquatic pest-
A plant, animal, or insect that interferes with the functions and use of an aquatic system

, Aquatic plant-
a plant that grows in water or in areas closely associated with water
Aquatic Resource-
A river, stream, lake, pond, or other body of water. Provides drinking water, recreation areas,
habitat for wildlife, and other benfits for people and the env.
Integrated pest management-
A system that uses all appropriate strategies to reduce pest populations. By using this you may
reduce the need for pesticides.
Nutrient Management-
Actions that reduce the amount of nutrients that flow into a body of water. Excess nutrients
cause weeds to flourish. By reducing nutrient runoff, __________ __________ may prevent a
weed problem before it starts
Pest-
any living thing that is undesirable to people or the env. An organism may be a pest in one
place, but not in another.
