INTRODUCED BOG PLANTS, VANCOUVER, BRITISH COLUMBIA - UPDATE
From: Frank Lomer, Honourary Research Associate, UBC Herbarium,
Vancouver, B.C. c/o <ubc at unixg.ubc.ca>
The following is an update of "Introduced Bog Plants Around
Vancouver", BEN # 104 - July 2, 1995.
Azolla caroliniana Willd. I have now seen this aquatic plant
from numerous places, especially around the extensive cran-
berry fields on the northeast corner of Lulu Island, Rich-
mond. This species can be invasive. One large slough in
Richmond (6m x 0.5km) was completely covered by a mat 1cm
thick. The plants themselves were in turn covered by aphids.
Also collected in a ditch at 10480 59th Ave., Delta. (Lomer #
95-222) I have seen A. caroliniana sold in a few garden
centers and this may be the source of our introductions.
Cyperus erythrorhizos Muhl. - I mentioned that the introduced
population at Richland Farms, 19611 Westminster Highway,
Richmond, may be extirpated, but it is still abundant in
cranberry fields about 1km west of where I found the original
Cyperus retrorsus Chapm. - A single plant, 1 meter tall, was
growing along the edge of a hog fuel track skirting the
perimeter of a large cranberry field. C. retrorsus is native
to the eastern U.S. and perhaps has not been collected in
Canada before. Collected from Richland Farms, Richmond on
September 28, 1995. (Lomer # 95-197)
Juncus canadensis Gay - I have found two new populations of this
species. It grows at Burnaby Lake and along the edge of a
tidal marsh, Pitt River, Port Coquitlam, 1km north of Pitt
River Bridge. (Lomer # 95-201)
Juncus pelocarpus Meyer - Since I wrote the original article, I
have found two new populations of this species. It is abun-
dant and widespread in Burns Bog, Delta and in a gravel pit
at 200th St.and 36th Ave. in Langley.
Muhlenbergia uniflora (Muhl.) Fern. - This distinctive clumped
grass with a diffuse purplish panicle is native to N.E. U.S.
and S.E. Canada. Collected in a weedy plot in a cranberry
field north of the Richmond Freeway about 1km east of No.8
Road, Richland Farms, Lulu Island, Richmond. Despite the
name, the plants I saw mostly had 2 florets. More than 50
clumps were seen in a field with Cyperus erythrorhizos
(abundant), Hypericum boreale, and Lindernia anagallidea
(few). (Lomer # 95-195, 95-241)
Scirpus atrovirens var. georgianus (Harper) Fern. - Collected on
June 23, 1995 on boggy shore of Burnaby Lake, 4km. east of
Vancouver (Lomer # 95-131), growing with Juncus canadensis
and Glyceria canadensis. A few days after I collected this
plant, the area was covered with gravel and this population
seems to be extirpated.
A NATURALIST'S GUIDE TO THE ARCTIC
Pielou, C.E. 1994. A naturalist's guide to the Arctic. Univer-
sity of Chicago Press, Chicago. 327 p. ISBN 0-226-66814-2
[softcover] Price: CND $29.95
When we visited Dr. Chris Pielou in their new home on Denman
Island quite a few years ago, she told us that her book on "The
world of northern evergreens" had just appeared and that she was
writing another book on natural history. She would not reveal
what it was about, but our good mutual friend told us (about two
hours later) that the book was to be on the Holocene history of
North America ("After the Ice Age" - published in 1991).
Chris Pielou was an eminent mathematical ecologist and she has
tried all her life to compress Nature into the bold print of
matrix algebra. In her books such as "Mathematical ecology" (two
editions), "The interpretation of ecological data...", "Popula-
tion and community ecology" - just to name a few, you easily
find sections which you cannot read unless you have a degree in
mathematics. You had to wonder, how the author saw the forest,
ecosystem, ecology, or a dandelion. Has she ever noticed them?
Open the "Naturalist's guide to the Arctic" and you will know
the answer. No bold matrix algebra, but a nice description on
how the Arctic works. You will learn about astronomy, climate,
geology, the ocean, plants and animals and all the interactions
and causal relationships that you have to know in order to
understand this particular biome. Everything is written in the
nice, clear style and all the stories are fascinating. I was
looking for the name of an artist who drew the nice pictures
(ranging from the Arctic landscapes, through plants, birds, and
mammals to the Cariboo Warble Fly) before I noticed that the
book was "illustrated with more than 400 of the author's draw-
ings and maps."
P.S. - Richard, can you tell us what is Chris working on now?
APOTHEOSIS OF BRITISH COLUMBIA
Mackenzie, Ian. 1995. Ancient landscapes of British Columbia.
Lone Pine Publishing, Edmonton. 128 p. ISBN 1-55105-043-9
[softcover] CND $24.95
"British Columbia is a beautiful place," told us the clerk of
the Canadian Embassy in Prague in 1969 after she stamped the
Canadian visa into our Czech passports. We understood what she
meant when we arrived to British Columbia few days later. Ian
Mackenzie's book is an extraordinary document of this extraordi-
nary province. It is the result of a six-year pilgrimage: Ian
Mackenzie has journeyed on foot and horseback, by canoe and
kayak, by air, river and ocean, to the most remote corners of
The photographs (we are told that they were selected from about
30,000 images) are overwhelming. I have not been able to read
the text - whenever I opened the book I had to look at the
photographs and I slipped into daydreaming about those sacred
places. From a short biography we learn that the author has a
Master degree in linguistics and speaks and read eleven
languages. In addition to his gift to communicate through his
The book is a "pictorial geography of British Columbia." The
biogeoclimatic map at the end of the book will give you not only
the distribution of our biogeoclimatic zones, but also refers to
pictures taken in the respective zones. In the text, paragraphs
printed in bold italics summarize the characteristics of each
biogeoclimatic zone. Great idea ! By the way, when Prof.
Vladimir Krajina introduced the term "biogeoclimatic zone" even
many professional people laughed to the seemingly useless tongue
twister he had created. Twenty or thirty years later this term
is a part of a picture book directed to a very wide audience and
nobody worries that the average reader would not understand the
concept of BIOGEOCLIMATIC zones.
The Lone Pine Publishing did an excellent job and produced a
remarkable publication. The Lone Pine Publishing have their

FOOD PLANTS OF COASTAL FIRST PEOPLES
Turner, Nancy J. 1995. Food plants of coastal First Peoples.

This is the second edition of Nancy Turner's 1975 handbook on
ethnobotany of British Columbia. The original edition has been
expanded and updated, with more colour photographs and with the
most recent additional literature references.
LOOKING FOR THE LAWS OF NATURE
For the April 1st issue of BEN I would like to compile a collec-
tion of known and unknown biological laws and postulates.
Klinger's law: Peatbogs always start being formed on the leeward
side of water bodies.
Ferdinand Kokoschka's principle: No excrement can be bigger than
the organism that produced it.
