** I have witnessed several varieties of Vaccinium (myrtillus and
uliginosum) being well visited by wild (as well as domesticated)
honeybees. In 1976 through 1987 I have cultivated/harvested and
wildcrafted vaccinium as well as photographed and recorded the
areas of its occurence in Sonoma. Marin, San Mateo amd Santa Cruz
counties as well as other areas in Northern California and the
Siskiyou Plateau. Since 1986/87 I have seen a general decline in
the number of berries per plant which coincides with a decline in the
number of wild/kept hives in those areas. While it is obvious that
the honeybee is not indigenous and vaccinium is, it still causes me
to reflect on the impact of the loss of the wild hives. In 1993 the
areas that I have grown over the years for the forage of wild hives
as well as my own (bottlebrush, clover, etc) revealed no honeybees
in an eight hour period (June 2nd, bright and warm with no wind).
That area was, in the past one of the busiest for bee traffic I
have ever seen considering it was at least 4 miles from any hives
(commercial). The decimation of wild hives in Northern Sonoma
county is almost complete. A clump of Rosemary that I have used for
over seven years to observe foraging bees which is about thirty feet
by forty feet was completely vacant earlier this year in prime
forage times. Bombus and one other small bee which I have heard
called a "sweat" bee were the only visible working foragers.
