program has been the Menzies or
Humboldt Bay wallflower (Erysi-
mum menziesii
ssp. eurekense). This
is a state- and federally-listed spe-
cies that is found in the fore dunes
surrounding Humboldt Bay. In
1976 the Army Corps of Engineers
planned to deposit the spoils from
harbor dredging onto the sand
dunes on the Samoa Peninsula.
In 1977, through the leadership
of John Sawyer, seeds were collected
and whole plants were moved to
new locations at the Lanphere
Christensen Dunes Preserve. The
Army Corps of Engineers also
agreed to preserve some of the habi-
tat that would initially have been
covered with dredged material. By
1979 relocated plants were doing
well and the protected population
was also thriving. The monitoring
of the plant continued throughout
the 1980s. An annual activity for
chapter members has been to count
individuals in each of the Menzies
wallflower populations.
In 1984 our chapter celebrated
when the wallflower was listed as
endangered by the California De-
partment of Fish and Game, and
again in 1992 when it was desig-
nated as endangered by the US Fish
and Wildlife Service (USFWS).
Presently, conservation issues are
focused on addressing sensitive
plant issues in the timber harvest
review process in Humboldt and
Del Norte counties, and reviewing
county management plans. We also
partner with the USFWS to collect
monitoring data on several of the
rare species in our area.
Part of our efforts to maintain
rare plant populations and native
plant habitat has been to control
exotic plant species. With the
CALTRANS development of the
State Route 101 corridor through-
out the 1960s and 1970s, many ex-
otic species were introduced to sta-
bilize the dunes and roadsides. Al-
though the chapter has focused on
many exotic plant issues, in the early
years the main concern was the in-
vasive plants in the dune communi-
ties at the Nature Conservancy's
Lanphere Christenson Dunes Pre-
serve. Pampas grass (Cortaderia
), English ivy (Hedera helix),
and yellow bush lupine (Lupinus
) are threats to the native
plants of the dunes.
In 1977 the chapter advertised a
"plant destroying trip" to the dunes.
In subsequent years these search-
and-destroy trips with a "Pulaski"
(axe) would be known as "lupine
bashes." In the spring 1998 issue of
Darlingtonia, it was suggested that
the lupine bashes were no longer
needed in some parts of the dunes
because of all the work done in pre-
vious years. Dune restoration con-
tinues today with weed eradication
workdays sponsored mainly by the
Friends of the Dunes, a local dune
conservation organization. In recent
years we have formed partnerships
with the Humboldt County Weed
Management Area in educating the
public about the invasive exotic spe-
cies in their own backyard. We also
have cosponsored California Inva-
sive Weed Awareness Week and a
guide to Humboldt County Weeds.
The success of our chapter
comes from the many hard-work-
ing and dedicated volunteers that
are found here on the north coast.
We have had 21 presidents in the
last 33 years with many serving more
than one term. What started as an
outgrowth of the HSU botany de-
partment has become a part of the
surrounding community with meet-
ings, field trips, and other activities
held throughout Humboldt and Del
Norte counties.
If you are ever in our area, please
come and visit us. Our business
meetings and evening programs are
held the second Wednesday of the
month, and always include a pre-
sentation. You can also check us
out online at
. We currently have 291 mem-
bers, including 21 board members.
Contact information for all of our
board members, including our new
chapter president, Carol Ralph, is
listed within our website.
