How do trees help fish? Seems kind of crazy doesn’t it? Well, it may be hard to believe, but there are a lot of benefits that trees have on our local fish population! In this presentation, we go over a few main contributions that trees have on fish. Let’s go over a few!
Shade. This summer was a scorcher! I don’t know about you, but I definitely took cover under the shade of a tree multiple times. why’d I do that? The shade not only protects you from the sun, but it’s also much cooler in the shade! Well the same goes for rivers and salmon! With more trees and other vegetation along streams and rivers the water is much cooler!
Erosion. This is a biggie! Imagine yourself grabbing hand-fulls of dirt. Roots from trees do something very similar. As they grow their root systems need to be more established to hold them down. By doing this, the roots grab onto more and more dirt. This keeps the dirt where it is instead of washing into the river!
Lets go over one more… BUGS! This is a two part explanation. As you know, bugs love to hangout on leaves and branches. So it’s logical that if there are more plants around rivers the more bugs there would be, which is great for salmon! Part two, the leaves that fall from these plants and trees are the basic food source for the smaller critters on the food chain! *Check out our macroinvertebrate page!

Now how-about some pictures!
