CALL FOR HELP: LUZULA MULTIFLORA GROUP IN THE PACIFIC NORTHWEST
From: Jan Kirschner @ Adolf Ceska, c/o [aceska at victoria.tc.ca]
We would like to repeat our appeal (cf. BEN # 95, May 16, 1995)
to field botanists in the western North America to help us with
the study of _Luzula_ sect. _Luzula_. In our area, this section
of the genus _Luzula_ is a mixture of introduced species ("_L.
campestris-multiflora_ group") and native species (such as _L.
subsessilis, L. comosa_ and several subspecies of _L. multi-
flora_). Plants of the genus _Luzula_ exhibit chromosome frag-
mentation ("agmatoploidy") and relatively simple cytoxonomic
techniques can answer many essential questions related to the
taxonomy of this group (Kirschner, 1992b). Karyotypes of western
members of _Luzula_ have been studied in only a few collections
(e.g., Nordenskiold 1951) and more examinations are needed to
solve our taxonomical problems. Jan Kirschner and the Botanical
Institute in Pruhonice near Prague (Czech Republic) would like
to help with cytotaxonomical investigations.
The best time to collect _Luzula_ specimens is when plants are
in full bloom. Flowering specimens are easy to identify. The
identification of specimens with ripe fruit is more difficult
and requires some experience. On the other hand, the identifica-
tion of specimens that are out-of-flower and don't have ripe
fruits is very difficult and often almost impossible (Kirschner
1982). When collecting herbarium specimens, collect plants with
underground parts and take notes of possible rhizomes & stolons.
More than one plant from a locality should be sampled; in
southern Europe, for instance, four species and three hybrids
were found at a single locality (Kirschner 1992a).
WE ARE INTERESTED IN GETTING RIPE SEEDS FOR CYTOTAXONOMIC
STUDIES! If you can, visit each locality twice and collect both
flowering and fruiting specimens. When collecting ripe, fruiting
plants, shake out seeds from capsules into small envelopes (each
plant into a separate envelope because several taxa can coexist
at one locality and, rarely, a hybridization may take place).
Without this precaution seeds of different collections can get
mixed up in the herbarium. Specimens should be dried in low heat
(30-40 deg. C). Do not freeze dry specimens!
We would greatly appreciate your co-operation. Please, send the
specimens and seeds to:

LUPINES AND BUTTERFLIES ON VANCOUVER ISLAND [Re: BEN # 243]
From: Cris Guppy [cguppy at quesnelbc.com]
The lupine article was quite interesting. Fender's Blue,
Icaricia icariodes fenderi, does not occur north of Oregon.
However, the Vancouver Island subspecies Icaricia icariodes
blackmorei is present. It has been virtually eliminated from low
elevations, due to the lack of patches of lupines of any size.
The butterfly is still known from a few subalpine habitats, such
as Mt. Brenton near Ladysmith, where increased lupine popula-
tions due to clearing and soil disturbance resulting from log-
ging (especially roads) had resulted in strong butterfly popula-
tions. The butterfly subspecies is provincially "blue-listed"
The herbivory on the herbarium specimens may have been due to
the larvae of the Blue, however it was more likely caused by
beetles that commonly feed on lupine leaves. If anyone knows of
low elevation southern Vancouver Island populations of lupines
of any species greater than (at a guess) 100 plants, it would be
worth looking for Icaricia icariodes blackmorei adults in May
and early June. Silvery Blue (Glaucopsyche lygdamus) adults may
also be present, with a faint possibility of the probably ex-
tinct Vancouver Island subspecies of Greenish Blue (Plebejus
saepiolus insulanus) also being present. The Greenish Blue
probably only fed on native clovers, but low elevation lupines
are a possible alternative.
NON-TIMBER FOREST PRODUCTS WORKSHOP - CRESTON, B.C.
From: Mike Keefer [mkeefer at cyberlink.bc.ca]
Ktunaxa Kinbasket Treaty Council is organizing a workshop on
non-timber forest products, May 23 and 24, 2000 in Creston, B.C.
(Lower Kootenay Band Gymnasium).
British Columbia's interior forests are a rich storehouse of
food, medicinal, industrial, aesthetic and spiritual resources.
Commercial interest in non-timber forest products (NTFP's) is
growing rapidly, but these many of these same products have
always been used by First Nations people. Commercial harvesting
of NTFP's is coming in conflict with traditional First Nations'
use in many parts of British Columbia. By bringing people
together to talk about these issues, future conflicts may be
This informal, interactive Workshop is designed for First Na-
tions people, wildcrafters, industry, consultants and research-
ers in NTFP.
NTFP is an industry in its infancy, so we have a chance to "get
things right," striking a respectful balance between traditional
First Nations use and sustainable commercial exploitation.
Finding that balance is the objective of this Workshop.
As a participant, you will hear dynamic speakers presenting many
points of view, and be able to put forward your own ideas and
questions. Display tables will demonstrate sustainable NTFP
products and projects. The rich cultural and ecological heritage
of the Lower Kootenay Band will provide a fascinating backdrop
for the Workshop. Participants may wish to come early for the
yakan nukiy Pow Wow, at the same location.
Directions to Lower Kootenay Band Gymnasium: from downtown
Creston, head south on Highway 21, following signs to US Border,
for approximately 3km. Turn left at yakan nuqiy Band sign and
proceed 300m to Gymnasium. Accommodations: several motels are
available in Creston. Camping spots near the site may be ar-
ranged by contacting Wilfred Jacobs at (250) 428-2719. For Pow
Wow information contact Lower Kootenay Band Office at (250) 428
Cost: payment received before April 28: $60.00
payment received after April 28: $75.00
For registration questions, contact: Kathy Tompkins, College of
the Rockies-Creston (250) 428-5332

Abstract: The vascular flora of the Arctic was surveyed by
specialists from eight arctic countries to: (1) identify rare
taxa endemic to the region; (2) establish an annotated list of
these taxa; and (3) determine the level of protection currently
afforded these plants. "Arctic" is defined as those lands beyond
latitudinal tree line. Ninety-six rare endemic taxa were iden-
tified. Information was compiled for each included taxonomy,
geographic distribution, habitat preferences, biological charac-
teristics, estimates of endangerment, and citations of support-
ing literature. Gap analysis determined the relation of rare
taxa to areas of protected habitats. Taxa were grouped into
three categories: (1) unprotected (no occurrences are within
protected areas); (2) partially protected (some occurrences are
within protected areas); and (3) protected (all occurrences are
within protected areas). Results indicate that 47% of the rare
endemics are unprotected, 23% partially protected, and 30%
protected. According to IUCN Red List threat categories, 19% of
the taxa are vulnerable, 29% near threatened lower risk, 26%
least concern lower risk, 1% endangered, and 24% data deficient.
The majority of rare endemic taxa, 61%, occur outside IUCN
protected areas (categories I-V); 25% occur within strict
nature/scientific reserves (IUCN category I); 12% in managed
nature reserves/wildlife sanctuaries (IUCN category IV); and
1.6% in national parks (IUCN category II).
