A Tree's Best Friend
(Note- this story is heavily drawn from my new favorite book The hidden life of Trees by
Peter Wohlleben)
I want to tell
you a story about good friends- the kind of friend who would feed you if you
were sick, and protect you if you were under attack.
The kind of
friend who, if she had baked some cookies, would give you one.
Even though
this sounds like a magical “once upon a time” story, it’s actually an amazing
“you won’t believe what scientists are learning” story.
If a tree had
a best friend of another species, what do you think it might be?
I’m going to
vote for… mycorrhizal
fungus!
Not just any
old fungus,
So far
scientists have identified 75,000 kinds of fungus in the world, and they think
there may be millions more!
some are enemies
of trees- they would eat a tree as soon as look at it.
But the oak
tree has a best friend called the Oak Milkcap

(Any fungus
that symbiotic association
between a fungus and the roots of a vascular host plant is called mycorrhizal )
A tree that
has a fungus partner can gather up to twice the nitrogen and phosphorus as
trees without- and trees need those chemicals to live!
and fungi get
something out of the friendship too- Fungi can’t grow their own food, they get
sugar and other carbohydrates from the trees-
sometimes up
to 1/3 of the total food a tree produces for itself.
SO the fungi
also help absorb heavy metals, which are bad for tree roots, and they help ward
off intruders, like bacteria or one of those enemy fungi.
They really
get to be dependent on one another.
But it doesn’t
have just one best friend, because the milkcap will roam through the forest
floor finding other fungi, and other tree roots.
These fungal
partners help make what is sometimes called “the world wood web”
One tree can
have as many as 100 different fungi connected to its roots.
And the fungi
many connect different species of trees.
And like our
human internet, trees share information through their web.
They warn each
other of an insect attack, so that trees can protect themselves by making
chemicals that are toxic or repellent to the attackers.
They pass on
genetic information so that the next generation can grow up more resilient
against threats their elders faced.
That’s why
when foresters cut down paper birch trees
their douglas
fir neighbors suffered too.
The
mycorrhizal fungi physically connect these two totally different species so
they can share resources and help one another.
A tree that
has a lot of sun can turn that sun into carbon, and then share the carbon
through the roots with another tree who needs it through the web.
This web helps
share nutrients and even water from a place in the forest where they are
abundant to a place where they may be scarce.
Today, after
you all are talking about magical beasts, we are going to stay and offer our
blessings to all the beings,
like Mycorrhizal
fungi, that we admire and love.
So I’m going
to add this photo of the Oak Milkcap to our altar here and say
“I ask for
your blessing for the Oak Milkcap, and all the fungi that partner with trees”
and then you
will say “May the Spirit of Life bless _________”
A Blessing for All Beings
In the
catholic tradition, it is common to celebrate a “blessing of the animals” near
the Feast of St. Francis. For centuries people have brought their dogs or cats
or goats and sheep to be blessed by a priest.
Today we want
to draw that circle even wider. As Unitarian Universalists we know that we are
part of an interdependent web of life that includes every being, from the
smallest soil microbes, to the tallest oldest trees. From the scary shark to
the snugly kitten. We know that even beings who don’t seem to have any
connection to our human lives are part of a profoundly complex system of
inter-relatedness, and are kin to us in ways we may never understand.
And so today
we honor and bless all beings.
What does the
word “blessing” mean to Unitarian Universalists?
First of all,
it’s not something only a minister can do- we are all directly connected to the
spirit of life which flows through us all. SO I am not going to do the blessing
today, we will all do it together.
We who gather
here are theists, and atheists and agnostics, so perhaps a blessing, for us,
means simply to hold in consciousness and compassion. To imagine the light of
life and love holding each of these beings, encouraging each to unfold in
whatever ways life calls to them in the community of beings.
I have some
extra objects here for folks that would like to ask for a blessing and don’t
already have something.
So as you feel
moved please come forward and add an object to our altar and say:
“I ask for
your blessing for ___________”
and then we
will all respond “May the Spirit of Life bless _________”
