Stages of a Dead Tree and the Importance of Snags

"Stages of a Dead Tree"

Click here to see the 2012 video

 

My topic is stages of a dead tree.  First I will teach you about the stages of a dead tree.  The next thing I will teach you how snags are important to animals.  Dead trees are super important to the forest.  They die back, fall over, and decompose to make rich soil.  Before they do that, they are homes for animals.  Usually, when you are walking on a path you pay attention to the living trees.  I am hoping my web page will make you more interested in the dying trees.  There are really cool animals that need them and interesting plants like moss and funky fungi grow on them.

Before we become a snag, I want to teach you about moss and funky fungi.  These plants start to grow on the trees before they are dead.  The make the tree start to decompose.  The moss and fungi use mechanical and chemical activity to break down the wood.  They help the rotting process.  They have chemicals in them that help to break the wood down.  The make the wood easy for carpenter ants and other insects to chew the wood.  This attracts the woodpeckers.

In this paragraph I will teach you about stages of a dead tree.  They are called standing dead or snags.  A snag is a tree that has died and is still standing.  There are three stages of a standing dead tree.  The first stage is the hard snag.  The crown is still intact and there are branches sticking out of the tree.  The bark is still on it.  The heartwood and sapwood in the trunk solid.  Woodpeckers begin to make holes in the trunk as they look for food [worms, insects, and bugs in the trunk].  The second stage is the soft snag.  The crown is gone, there are just a few branches still there and the bark is falling off the trunk.   The trunk is softer and it is easier for animals to make holes and dig into the tree.  Porcupine is really good for digging into the tree.  Nuthatches and chickadees keep try lloking for food and make the holes bigger.  Bats like sleeping under loose bark while they digest insects.  The third stage is the buckskin snag.   There is no crown, branches, or bark on a bucksking.  The trunk is the softest at this stage.  Now the holes are big.  The animals that live there are cavity dwellers.  They don't dig their own holes, they look for holes that have already been used by other animals.  These are the owls, raccoons, and martens. 

 

In this paragraph I want to talk more about how the snag is important to animals to survive.  In my research, I found out that there are 1,200 species that depend on snags for their shelter, nesting, or food.  The cavity homes let animals survive in extreme cold and hot, hot temperatures.  Chipmunks and squirrels store their nuts in holes until winter time.  Goshawks, great grey owls, and eagles build their nests at the top of snags.  A snag has its own ecosystem.  It has its own predators, consumers, and decomposers.      

 

I have taught you all I have learned about the stages of a dead tree returning to soil.  Now I hope you have become interested in looking at the snags as much as the living trees in the forest.  Now you can maybe teach this information to sister or brother.  They will be shocked.  I hope you had good time reading my paragraphs.
