Elephants are truly incredible animals.August 12 is World Elephant Day which means to help save elephants.What do you know about elephants?Here are some facts you may not know.

We know that elephants are large.But did you know that elephants often avoid eating a type of acacia tree(金合欢树),because it is home to ants?And an elephant doesn’t want to get the ants inside its trunk.Its trunk is full of sensitive nerve endings.

Female elephants live in groups of about 15 animals.The oldest in the group is the leader.She decides not only when and where they move but also when they rest all the year.Male elephants leave the female groups between age 12 and 15.But they aren’t loners.They live in all-male groups.

Asian elephants don’t run.Running requires lifting all four feet at once.But elephants filmed in Thailand always keep at least two on the ground at all times.

Elephants have passed the mirror test.They recognize themselves in a mirror.According to tests,great apes,and dolphins also have this ability.

Elephants can get sunburned so they take care to protect themselves.“Elephants will throw sand on their backs and on their heads to keep them from getting sunburned and to keep bugs off,” said Tony Barthel,working at Smithsonian’s National Zoo.How do elephants protect their young?Adult elephants will put them in sand and then they will stand over the little ones as they sleep.

Some farmers in Kenya protect their fields from elephants by lining the borders with beehives.Not only are their crops saved,but the farmers also get more money from honey.

Would it surprise you to learn that,like animals,trees communicate with each other and pass on their wealth to the next generation?

UBC Professor Simard explains how trees are much more complex than most of us ever imagined.

Although Charles Darwin thought that trees are competing for survival of the fittest,Simard shows just how wrong he was.In fact,the opposite is true:trees survive through their co-operation and support,passing around necessary nutrition “depending on who needs it”.

Nitrogen(氮) and carbon are shared through miles of underground fungi (真菌) networks,making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy.This hidden system works in a very similar way to the networks of neurons (神经元) in our brains,and when one tree is destroyed,it affects all.

Simard talks about “mother trees”,usually the largest and oldest plants on which all other trees depend.She explains how dying trees pass on the wealth to the next generation,transporting important minerals to young trees so they may continue to grow.When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed,we are reducing the chances of survival for the entire forest.

“We didn’t take any notice of it,” Simard says sadly.“Dying trees move nutrition into the young trees before dying,but we never give them chance.” If we could put across the message to the forestry industry,we could make a huge difference in our environmental protection efforts for the future.
