Do trees stress when a human is near them?

Question

i read somewhere that trees stress when a human is within 300 meters and is called "human stress syndrome" the cellwall of the tree begins to brittle and so a falling tree makes a different none cracking sound when humans aren't no where near them, they also make better woods for houses, they say if u built a house with a tree that is not stressed by humans then your house will eventually collapse, is this true because i find it hard to believe, anyone know anything about this?

Answer 1

I'd believe that a tree would only stress when a human has a chainsaw. ha ha.

No, actually, trees don't stress around people. :-)

Answer 2

depends on who comes near them ,if it is a tree hugger ,they may be happy .if it is a guy with a chainsaw ,they probably freak out

some information indicates that plants do have feelings,emotions and maybe even intelligence.

The north American Indians ,dance around a tree singing that they are going to kill it,they then quickly turn around and chop its neighbor down,taking it by surprise.
this suggest that they believe the tree has feelings.

Plants belonging to people with green fingers ,who talk to their plants ,often do better.

There once was a famous experiment,whereby 7 people walked into a room where there was a big plant,that was wired up to a lie detector.
One of the people had a knife and cut some parts of the plant.
then later when the people were brought before the plant again,the lie detector gave a violent leap in its readings ,when the person with the knife was brought before it.
the same experiment was done with trees and in all cases the same result.
so who says who has feelings or souls.

intelligence??????
a eucalyptus tree when it is being attacked by a Caterpillar sends messages via pheromones trough the air which are picked up by similar trees often many miles away.
when the caterpillars reach this tree it is ready for them and kills them with a poison ,that it has developed in the meantime and secretes trough its leaves.

there is more to trees than meets the eye

Answer 3

Trees are living systems. Every living system will do
something when its survival is threatened. Trees are
systems that came from genetic codes. The systems do
have limits. When any agent causes the system to
operate near its limits, then the system becomes
stressed. When the potential survival - threatening
agent continues to exert a force, then the tree system
could go from stress to strain.

Even though plants do not show any changes to the naked
(or lensed) eye, when a human is in their presence
systemic biological changes have been discovered that
have grave effects on plant life when a person is
within 300 meters. This effect is called "human stress
syndrome".

Answer 4

I know Pine trees that fear me. I don't know about stress though. I work in a Lumbermill and i cut Pine for a living. I am pretty sure the trees know what i am doing in that building.
