One summer day in the year 2008, Coyote was dreaming in a hole, underneath an oak tree on San Bruno Mountain’s Owl Canyon.  Flames came roarin’ up through the cherries.  The fire jumped from oak to manzanita, hopped onto fescue, and snuggled with lotus.  Coyote said, “My prized cave!”

Coyote slid in by some crystals, next to horsetails and ferns, and waited for the fire to pass.

Image

Canyons of dense green leaves turned into black earth.

Image

It all went up in smoke.

Image

After the fire cooled, Coyote followed old trails and ate a few broiled snakes.

Image

The blackened earth went green soon after the first rains of the fall.

Three years passed.  Blue blossom seeds buried deep in the shade made dense thickets.

Image

Cramp ball fungus ate dead oak trees.

Image

Yerba Santa, who hadn’t been seen around these parts in many years,  bathed happily in the sun.

Image

Fat and ancient black heads of fescues sprouted tender thin leaves.

Panther’s amanita bulged under the oak trees.

Coyote smiled at fire’s footprints and remains.  What is Fire?  Fire is mother earth’s gardener.  She rakes clean the leaves.  She prunes the trees and shrubs.  She fertilizes the earth with carbon and phosphorous.  Fire scars dormant seeds and bathes the land with light.  Shady woods open their canopies.  Old trees turn into a fungal feast.  The young burst forth in grasslands rich with diversity.

Tired manzanita branches are burned to the ground.  The new leaves come up from the base.

California bay is not dead, just renewed.

Image

Fire is a chrysalis.  Fire is the light of destruction.  Fire is frightening.  Fire is a being of energy.

Coyote came to an overlook, and saw this strange animal.  Crouched in reverent prayer, or perhaps preying on her gophers?!

What is so funny?!  This is home.

Any chance to play with water I am there!  So washing dishes comes easily to me.  Restaurant, home, or camp site – they are all good places to do some chores.  Luckily there is the magical stuff called soap, otherwise the  greasy film on the pots and pans would drive me nuts!  The plastic forks and tupperware containers, boy they really hold on tight to the oils.

The water molecules gather around the tail of the sodium or potassium part of the soap, and keep the soap molecule suspended in the water.  Meanwhile, the other end of the soap molecule grabs onto oils and dirt.  Soap helps make an emulsion – a mix of two liquids that do not usually blend together.  Then it’s off they go to the sewers, treatment plant, bays and oceans.

Another day I was working in the garden, cutting tree branches.  Saw dust was flying in my eyes, the saw teeth were trying to jump on my arms, and the weight of the branch was starting to pinch.  What is this stuff that is so strong?  When I understood, I drew this picture.  It is all in the structure.  Wood shares some similarities with rebar and concrete, bones and muscles, wood frames and drywall.

There are organisms that like to eat wood and break it down into tasty morsels.  Fungi!  Some are picky eaters, and they only relish the brown lignin cores.  They are called white rotters because they leave a bunch of stringy white fibers after their feasting.  Here is one of them:

Fungi comes in many forms and colors, and can be found everywhere.  Fungi loves moisture.  Nature’s house cleaners take care of the dead, and sometimes parasitize the living.  The dry rot that eats my deck is a brown rotter.  It will slowly eat the cellulose (and hemicellulose) until the deck crumbles into little brown cubes.  Arrgggghhh!  Should have used redwood….

Here is a story about parasites in the Mojave desert.  There are beetle larvae that take up residence in bee nests.  It is a little disturbing, but still suitable for younger audiences.

This was a story for a kindergarten class that was studying the sea and all its creatures.
