Why do squirrels strip the bark off trees ?

Does it kill the trees, it surely can't do them much good ?Why do squirrels strip the bark off trees ?
They strip bark off certain trees to get to the tender cambium layer, which they eat. The theories about pregnant females and searching for water, are just that, theories. Squirrels will strip bark even during wet, rainy weather. And yes, they have been known to kill trees. Porcupines are even worse, since cambium bark is one of their main sources of food.Why do squirrels strip the bark off trees ?
who cares if they use there teeth the qestion was why ^^lol


Anyways... They strip the bark because of...





1.Gnawing in search of water. This theory looks at bark stripping which occurs during the dry months.


2.Gnawing to cope with pain. The idea behind this theory is that pregnant female squirrels late in their term, don't eat. So the belief is that they gnaw on bark to cope with the pain.


3.Gnawing in search of food. This theory holds that squirrels are gnawing in search of the inner bark that would satisfy a particular nutritional need.
they do it cause they get tired and they're bored, but it's pretty much like going to the beach all day then you come home all sunburnt then you ask your boyfriend to scrape the dead skin off you. it's pretty much that.
they do it to eat the zapp from the tree (underneath the bark)
They use there teeth rite??
