a while. If you find a pair of trees
like this, take a photo or sketch the two crowns. For
comparison, you can draw or photograph two trees
that are not friendly. And because true tree partners
are so
rare,
you can share pictures with your friends
to
see
who has spotted the most.
Old Tree Stump
HOW
CAN YOU RECOGNIZE AN OLO tree stump?
A fresh slump has hard wood in the middle, and
often it is still light-colored. With
an old
stump, the
wood is already dark and rotten, and it breaks up
easily
when you
touch
it.
If
an old
stump
is still
alive,
the bark around the outside edge will be tightly
attached.
If the bark on the outside is falling off, it
means the tree is dead.
These two trees are growing together,
connected by their roots.
If you come from a big family, you probably have lots of other relatives besides
your parents.
You
might have siblings, cousins, aunts and
uncles,
and grand-
parents, too. But how do the trees in the forest know who is related to whom?
WHEN
IT
COMES
TO
TREES,
THAT'S much harder to figure
out
than
it
is
for
humans.
After
all,
we
can ask
questions
and get
answers.
And sometimes family members look
so much alike that we know even without asking that
people are related.
Trees recognize each other differently. They
communicate with each other through their roots
below the ground. Trees can feel more through the
tips of their roots than we can with our
fingers.
They
can even make decisions with them! A root tip Is
almost like
a
small brain.
If
a
tree's roots meet those of
a
neighboring tree,
they can check whether they belong to the same
species, If so, then those trees are probably part of
the same family. Now their roots will grow together.
The
trees
