What is picking up, bagging, and throwing your dog's poop away! (and in some cases, composting it)
Name an important and easy BMP (Best Management Practice) that your parents may ask you to do when walking your dog.

100

Fertilizer, household cleaners, detergents, animal waste and manure, treated and untreated municipal sewage waste
Name two sources of phosphorus.

100

Invasive species are known to have a direct negative impact on an ecosystem while non-native species do not cause any harm to an ecosystem.
What is the difference between a non-native species and an invasive species?

100

What is impervious
What type of surface is concrete?

100

What is clear-cutting
What is the most harmful method of logging?

200

What is a rain barrel
These can be used to collect water at the bottom of a down spout.

200

Algae Blooms
What is cyanobacteria?

200

What are preventative strategies and education.
What is the most effective BMP for aquatic invasive species?

200

What is salt and sand
Although it is necessary to spread this on icy roads during the winter, rain events in the spring can wash what into our rivers & streams?

200

What is erosion
Cutting down trees or removing vegetation on a slope can often cause this event to occur (hint: something with soil movement)

300

What is a rain garden
Installing one of these can absorb sitting or excess water after a rain storm that would otherwise runoff into a storm drain or waterway, plus it adds a touch of color to your yard!

300

Algae blooms are most common in the summer in warm shallow bays.
Where and when are algae blooms most common?

300

Once an invasive species makes its way into the lake it is almost impossible to eradicate. That is why it is important to work to manage and try to control the impact that the species has on the lake.
What can be done once an invasive species makes it way into the lake?

300

What is silt fencing or sod
Erosion can be controlled at construction sites by using these materials

300

What is a floodplain
This area helps to naturally store water in minimize impact during severe weather events.

400

What is phosphorous. Phosphorous is often unnecessarily added to household products such as detergent and soap, and used frequently on private & public yards to increase vegetation growth. During a rain event, phosphorous clings to soil particles and is carried into our waterways in the form of runoff. However Vermont no longer allows phosphorus in many household detergents and cleaners.
This element is found in soaps, detergents, animal waste, fertilizers and naturally in the earth (rocks and soil)- but often makes its way into our waterways in high and damaging levels. Name what this element is, how it gets into our lakes and rivers, and some of the negative impacts it has

400

1. Education of farmers and people living in the watershed, 2. Riparian Buffer Zones along streambanks and shorelines, 3. Vermont has very good soil and often times does not need fertilizer 4. Leave grass clippings on your lawn as this recycles nutrients, 5. Plant rain gardens or utilize rain barrels
Name two BMPs to help reduce phosphorus in the lake.

400

What are educational signs reminding people to clean their boats, and stewards on site to help remind people to clean their boats and motors.
What is one BMP that marinas can use to help prevent aquatic invasive species from getting into the lake?

400

What is pouring it down the drain or storm sewers
This is an improper way to dispose of your household hazardous wastes, such as antifreeze, paint, or oil.

400

What are riparian buffer zones
These can help to stabilize stream banks, minimize erosion, and infiltrate water from runoff.

500

What is a storm water drain
These are common in residential areas and are often where runoff from lawns, sidewalks, and streets ends up

500

An excess amount of phosphorus runs off into the lake causing accelerated growth of plants such as blue-green algae. The algae begins to create a layer on top of the lake which blocks out sunlight from plants on the bottom of the lake and they begin to die. This then causes a decline in dissolved oxygen in the water which can cause fish to die off. At the same time the algae can release toxins into the water which can make living conditions for fish even more difficult. The area soon becomes a dead zone with few living organisms.
Explain the process by which eutrophication occurs.

500

Spiny waterflea, alewife, zebra mussels, eurasian water milfoil, water chestnut, sea lamprey, These species can outcompete native species for food and and space.
Name two aquatic invasive species in found in Lake Champlain today and explain one impact they are having on the ecosystem.

500

What is a green roof. Green roofs can absorb rainwater and minimize runoff, they can work to mitigate the urban heat island effect, and they can also be aesthetically pleasing and provide a green space in the city.
This method of green infrastructure is becoming increasingly popular in cities. Name what it is and explain two ecological benefits.

500

What is: •Honey Suckle •Japanese Knotweed •Glossy Buckthorn •Garlic Mustard •Purple Loosestrife •Japanese Barberry •Emerald Ash Borer •Asian Long-Horned Beetle •Poison Parsnip (wild parsnip) • and many more... The direct threats of invasive species: • preying on native species • out-competing native species for food or other resources • causing or carrying disease • preventing native species from reproducing or killing their young
Name at least one of the most prolific (abundant) invasive species in Vermont forests today and give two ways that invasive species can be harmful to an ecosystem.
