NATIVE VEGETATION SYMPOSIUM - UNIVERSITY OF VICTORIA - MARCH 9
Saturday, March 9, 1996 - Native Vegetation Symposium University
of Victoria, Elliot Lecture Wing, 9:00 a.m. to 5:00 p.m.
You are cordially invited to the third annual Native Vegetation
Symposium being held on March 9, 1996, at the University of
Victoria, Victoria, British Columbia. The Native Vegetation
Committee of VIPIRG (Vancouver Island Public Interest Research
Group), which is putting on the event, is dedicated to identify-
ing issues relating to native vegetation. Our main aims include
education and conservation. Funds raised from the symposium will
be used for continued upkeep of the UVic Native Plant Garden
along with other committee activities.
The aim of the symposium is to expand people's knowledge about
native vegetation issues (see below). Other events include tours
of the Native Plant Garden, lunch time theater and art, book and
plant sales, displays by local organizations, and a raffle
offering great prizes.
Admission is $8 for students, seniors and unwaged, $10 for
others. Tickets can be obtained in advance by contacting Brenda
Costanzo at the UVic Herbarium (604) 721-7097. As well, we have
group rates for ten or more people ($5 each). The symposium is
being held in the lecture wing of the Elliott building and will
run from 9am to 5pm. Please bring your own mug for refreshments.
We hope to see you there!
Speakers will include: Hans Roemer (Rare Plants of B.C.),
Neville Winchester (Canopy Research), Willie McGillivray
(Wildlife Habitat Creation), Greg Allen (Garry Oak Pollen of
Heal Lake), Nancy Turner (Ethnobotany), Allison McCutcheon
(Medicinal Native Plants), Penny Kerrigan et al. (First Nations'
Perspective), Jeff Ward & Joel Ussery (CRD Green Spaces
Strategy), Adolf Ceska (Rare Aquatic Plants), B.C. Native Plant
Council Meeting, Brenda Constanzo (Native Plants in Garden), and
Paul Allison (Holistic Approach to Native Plants).

NEW SPECIAL FEATURE PROTECTED AREAS ON VANCOUVER ISLAND
From: Kerry Joy <KJOY at galaxy.gov.bc.ca> and
Hans Roemer <HROEMER at galaxy.gov.bc.ca>
The establishment of 35 new small protected areas on Vancouver
Island brings the protected area, parks and ecological reserves,
total to 13% of the Island's total area. This objective was
established in the June 1994 "Vancouver Island Land Use Plan"
which was designed to protect the Island's natural environments.
The 1994 plan established 23 large and representative protected
areas ranging in size from the 600 ha Davie River area of old
growth forest to the 10,600 ha Nahwitti-Shushartie at Vancouver
Island's northerly tip which protected a portion of the Nahwitti
Lowland.
The new areas range in size from the 2 ha Hudson Rocks, a na-
tionally significant pelagic cormorant breeding colony, to the
3,000 ha Quadra Island Main Lakes chain noted for its scenic,
recreational, and fisheries values. These areas total 11,857 ha
and represent special feature provincial parks and ecological
reserve candidates. Some private lands are included in the 35
areas which will require purchase or land exchange negotiations.
The selection of these areas resulted from wide public and
institutional input including First Nations concerns, naturalist
groups, individuals and key provincial and federal government
staff. This process resulted in some 300 suggestions totaling
35,000 ha and 78 highly valued areas. The 11,770 ha ceiling
caused further study with a final selection of the 35 Crown and
private land areas.
What is in it from the botanist's perspective? Just like the
1994 set of large, representative areas, all these new areas
contain some undisturbed ecological and botanical features of
interest, most of them still to be discovered and described by
botanists. So only some highlights can be mentioned for some
areas where we do know them:
Comox Lake Bluffs - Botrychium simplex, Polystichum imbricans
Klanawa River - BC's only extensive stands of Oxalis oregana
Ladysmith Bog - Utricularia gibba
San Juan Estuary - Only locality of Mimulus dentatus in Canada
Woodley Range - Lotus pinnatus, Aster curtus, Isoetes nuttallii
Somass River Estuary (...if negotiations are successful)
- Sidalcea hendersonii, host of rare mudflat plants
Somenos Garry Oaks (also under negotiations) - Viola praemorsa
Niagara Creek (under negotiations) - old growth Douglas-fir
Botanists familiar with some of these sites may wonder why they
have received park status and why those with important botanical
features have not become ecological reserves. The answer is that
the present action is intended to secure the land base and that
ecological reserve status is still considered as a future option
for several of the sites.
Even botanists can't have everything: Some precious spring
ephemerals at Koksilah River, Canada's only Euonymus occiden-
talis at Tsolum River, and the unique diversity of wetland
plants at Moran Lake go without protection, to name only a few.
CAVE FOSSILS OF PRINCE OF WALES ISLAND, ALASKA ARCHIPELAGO
From: "Timothy H. Heaton" <theaton at sunflowr.usd.edu>
originally on SITKA <sitka at sunflowr.usd.edu>
I just received a 1983 article by Knut Fladmark via ILL where he
states:
North of the Queen Charlotte Islands, the Alexander Ar-
chipelago of Alaska represents a troublesome gap in
Quaternary environmental data. ... it is likely that the
outer headlands and slopes of Chichagof, Baranof, and
Prince of Wales Island remained unglaciated, although
possibly separated by ice lobes reaching the Pacific ...
I'm happy to announce, Knut, that the gap you spoke of is now
being filled and that your claim of coastal refugia appears
vindicated!
My work in SE Alaska began when an old friend of mine (Kevin
Allred of Haines AK), while exploring caves in the extensive
karstlands of Prince of Wales Island, began discovering exten-
sive fossil deposits--primarily ancient bear dens. Two caves
have been fully excavated so far: El Capitan Cave (near a bay in
a glacial valley) and Bumper Cave (subalpine). Both caves con-
tain remains of postglacial brown bears (which were previously
thought never to have reached the southern Alexander
Archipelago), and two other species recovered are caribou and
red fox (which no longer inhabit the archipelago or the adjacent
mainland). Radiocarbon ages range from 12,300 to 7,000 YBP and
show that the glaciers melted earlier than previously thought.
El Capitan Cave and other coastal caves also contain black bear,
otter, and fish (otter scat) remains.
The most exciting cave to date is On Your Knees Cave where
remains of a 17,500 YBP seal, a 35,000 YBP brown bear, and a
42,000 YBP black bear have been found. This cave (on the extreme
northern tip of POWI) seems to have remained ice-free throughout
the glacial peak, and it shows that brown bears have a long
history in the archipelago. At the same time that we discovered
these fossils, Gerald Shields and his student Sandra Talbot in
Fairbanks were doing a DNA study and finding that the living
brown bears of the northern archipelago (ABC Islands) are
genetically distinct from all other populations and are more
closely related to polar bears than to their mainland con-
specifics! Gerald can post the details. The combined evidence
suggests that brown bears have had a long-term coastal refugium
in SE Alaska and are not postglacial immigrants.
On Your Knees Cave will be a primary focus next summer. We will
also be excavating a cave where Joe Cook found a marmot tooth
that is beyond radiocarbon age and and another cave where we
found a bone spear point associated with two 8,600 YBP black
bears. I want to acknowledge my two primary excavation partners,
Fred Grady and Dave Love, two very supportive Forest Service
scientists who live on POWI, Jim Baichtal and Terry Fifield, and
the current leader of the Tongass Caves Project, Steve Lewis,
all of whom are here on the list.
The need for interdisciplinary research has become increasingly
apparent. Lab researchers in radiocarbon dating, stable
isotopes, ichthyology, and palynology have provided crucial
information. Archaeologists such as Jim Dixon who are looking
for glacial-age human remains in the archipelago are very inter-
ested in our findings, and the need for cooperation there is
obvious. More troubling is our lack of knowledge concerning
patterns of glaciation and sea level changes--the very things
that would help us find potential refugia and ancient coastal
caves. As I mentioned earlier, the Canadians working in B.C. are
way ahead of those of us doing research in SE Alaska, so a forum
for discussion will be most beneficial. I'm delighted to see so
many top-notch Canadian Quaternary scientists on the list as
well as landmark researchers of the north Pacific Coast such as
Cal Heusser. The interest among coastal researchers in
Washington and Oregon is also encouraging.
