Clear selection

What restoration actions made the biggest difference for the species on the Backyard Team?

1 point

Channels with small gravel to suit their smaller body size.

Clearing barriers for a more swift passage from spawning grounds into the open ocean.

Improving the quality and quantity of stream and riparian habitats.

Clear selection

1 point

True

False

Clear selection

How does the Storm Drain Marking Program help salmon?

1 point

The program helps remove barriers to fish passage.

Drains are cleared regularly to prevent flooding and keep water flows stable in nearby streams.

A yellow painted fish is a simple reminder to people not to pour chemicals down the drain.

Clear selection

What is the another for Steelhead Trout?

1 point

Rainbow

Keta

Chum

Clear selection

Where should you plant a tree to save a salmon?

1 point

In the forest to prevent soil erosion into clean streams.

On the stream bank to shade shallow pools full of vulnerable fry during hot summer months.

Between off-channels to prevent the water from moving back and forth across the alluvial fan.

Clear selection

Erosion, which is harmful to salmon habitat, is a human-caused phenomena.

1 point

True

False

Clear selection

Which type of infrastructure can be made more "fish-friendly" by adding baffles or gravel?

1 point

Box culverts

Weirs

Alaskan steep passes

Clear selection

Why does adding large rocks or trees to streams make for better habitat for the Backyard Team?

1 point

It creates bigger pools for young salmon to rear in.

It creates more hiding places for young salmon.

It offers a place for young salmon to shelter during bad winter floods.

All of the above

Clear selection

This natural feature is stable during a high water event and offers a complex structure for fish to hide in during flooding:

1 point

Clear selection

If little Coho are usually able to get over a beaver dam after a heavy rain, when do beaver become a problem for salmon?

1 point

When they destroy valuable spawning habitat.

When the dam is on a groundwater channel that won't receive any flood water to help push them over.

Newly constructed off-channel habitat.

Natural off-channel habitat.

Clear selection

When is off-channel habitat *critical habitat* for Coho salmon?

1 point

During spawning

During rearing

During winter rearing

Clear selection

In the Coquitlam River, increasing the critical off-channel habitat for Coho salmon by 10% more than doubled the number of wild Coho produced over a period of ten years.
