A marvelous, astonishing sight west of the Rocky
Mountains was a valley that looked like a blue sea with gentle
waves rippling across it. A dense carpet of blue flowers stretched for miles deceiving the eye to the point of looking like a vast lake.
The flowers, unknown to them, were the camas lilies (Camassia quamash) of the
west. They look like small lilies, although they are more closely related to
the agave than to other lilies. Their nutritious bulbs provided an important food to the local peoples. Despite the laborious preparation to eliminate toxic
components the Nez Perce and other tribes resorted to this food through the
winter pounding it into flour and baking it into bread-like cakes. Lewis and
Clark were happy to supplement their dwindling supplies by purchasing camas lilies
cakes from the Nez Perce.

Most of the land of the camas lilies has been taken for
cultivation of crops. We can only imagine the full glory of the blooming fields
of two centuries ago when looking at the scattered small plots which represent
their last remnants.
One of the familiar things the expedition members left
behind was the honey bee or domesticated bee. There were no domestic bees west
of the Mississippi
in those days, only native ones. It would take another fifty years for some enterprising folks to
carry beehives from the eastern United States
to California.
Only one hive survived the ordeal of such a trip. Many years passed before
honey bees became established and significant beekeeping operations got
underway.

Camas lilies were not deprived of pollinators. They had no
need for honey bees; abundant insects made their living from gathering their
pollen and nectar. When the new crops and agricultural methods including
monocultures took over much of the land, the honey bee became the workhorse of
crop pollination.

Where did the native pollinators go after the numbers of
camas lilies shrank to insignificance? Probably we'll never know. We can guess
that some found pollen and nectar elsewhere and survived, although their
numbers, too, must have been reduced. We acknowledge the disappearance of a way
of life and of the seas of blue flowers. The pollinators of centuries ago went
about their job silently and unnoticed. Thus, we cannot appreciate their
absence.

This is great stuff, Beatriz. You have made science accessible to the layperson. I always enjoy reading your articles.
