The above pool has quite a tadpole
count for its size.  The pool is rapidly
shrinking.   Low seasonal rainfall
has effected the local water tables.  
These pools are breeding habitat for
redlegs, chorus frogs, and boreal
toads.  The pictures on the right
depict the outcome of this
unsuccessful race against  time.
Some of the pools dry up before the
larvae even start to grow legs.
Tadpole predator:
Predacious Diving
Beetle Larva
Complete dessication:
Some of the bottoms looked like
this "Last Stand"; others were
picked completely clean by
shorebirds.
