PROCEEDINGS SAVED (RE: BEN #35)
>From: Susanne Rautio c/o aceska@cue.bc.ca

The Proceedings of the Symposium on the B.C.'s Threatened and
Endangered Species have found a sponsor. They will be published
and distributed by the B.C. Federation of Naturalists, 321-1367
W. Broadway, Vancouver, B.C., V6H 4A9. Many BEN readers were
interested in the Proceedings and some suggested that the
Proceedings should be made available as an electronic file.


GROVE OF BIG WESTERN HEMLOCK TREES
>From: Adolf Ceska and Hans Roemer

A grove of big western hemlock (Tsuga heterophylla) was reported
to us by two employees of the MacMillan Bloedel Company. The
grove is situated in a subalpine bowl at 750 to 950 m elevation
and has near record-size hemlock trees scattered in the
amabilis fir forest. Two biggest trees had DBH 2.52 and
2.38 m and height 38.71 and 52.12 m, respectively. The British
Columbia record tree has DBH 2.59 m and height 54.88 m. The
grove is at the headwaters of the Cous Creek SW of Port Alberni
on Vancouver Island. The MacMillan Bloedel wants to log a part
of the grove in 1993, but we recommended to protect it as
"pocket wilderness."


GEUM CALTHIFOLIUM
>From: Terry Taylor c/o rtaylor@cue.bc.ca

On July 16 I discovered a small population of Geum calthifolium
at the  base of the West Lion, and made a small collection which
I gave to Olivia for the U.B.C. collection.  They had some
previous material collected by Fred Perry and John Davidson in
1914 and 1915, but no later collections from this far south.  


THREATENED STAND OF GARRY OAK IN DUNCAN
>From: Adolf Ceska <aceska@cue.bc.ca>

An interesting Garry oak site in Duncan (Vancouver Island) is
threatened by a near-by subdivision. Although the stand
bears signs of heavy grazing (dominant ground cover is orchard
grass - Dactylis glomerata), it has some interesting native
plants, such as a large population of upland yellow violet
(Viola praemorsa). On the transition between the forest edge and
wetlands we found a large population of tall woolly-heads
(Psilocarphus elatior - the 3rd extant population in B.C. I
know) and a smaller population of needle-leaf navarretia
(Navarretia intertexta - less than 10 populations known in
B.C.).


ANCIENT EVIDENCE SHREDDED
>From: Times-Colonist @ Ring

Last year the Capitol Regional District (CRD) drained Heal Lake
in the Victoria Highlands in order use it as a garbage dump. 
The peaty deposits of the lake bottom offered a long
palaeobotanical and dendrochronological record for the last
12,000 (or so) years. In order to assist Dr. Richard Hebda with
the work on Heal Lake, the CRD gave him a small grant. What they
did not give him, however, was the time needed for collecting
dendrochronological data. One day logs from the lake were
hauled to a heap and few days later were shredded for hog fuel.


TWO RECREATION BRANCH TECHNICAL REPORTS
>From:  Terje Vold, BC Forest Service, Recreation Branch

We've just completed two reports which may be of interest to BEN
viewers:

1. An inventory of undeveloped watersheds in BC (larger than
      5000 ha).
2. Undeveloped watersheds on Vancouver Island larger than 1000
      ha.

If any one would like a copy, give me a call at (604) 387-8482.


AGRIMONIA REQUEST
>From: Naohiro Naruhashi, Toyama, Japan

I would greatly appreciate seeds of Agrimonia striata and of any
other Agrimonia from your area for our cytological studies of
Agrimonia. Dr. Naohiro Naruhashi, Department of Biology, Faculty
of Science, Toyama University, Gofuku, Toyama 930, Japan.


PINK AGOSERIS IN THE ROCKIES (see BEN #24)

Bill van Dieren reported pink Agoseris (A. lackschewitzii) from
Bald Hills above Maligne Lake.  Agrostis lackschewitzii was
described in 1990 by Henderson & Moseley (Henderson, D.M., R.K.
Moseley & A.F. Cholewa. 1990. A new Agoseris (Asteraceae) from
Idaho and Montana. Systematic Botany 15(3): 462-465). 
Agoseris lackschewitzii is related to A. aurantiaca and A.
glauca :

              A. lacksch.  A. aurantiaca   A. glauca 

outer           villous        ciliate       villous
phyllaries      obtuse         acute         acuminate
                eglandular     eglandular    glandular

beak            < body         > body        < body

anther tube     1.2-1.8 mm     1.5-3.0 mm    3.5-6.0 mm

flowers         pink           orange        yellow

Agoseris elata (not in B.C., but south) has a beak longer than
the achene body and glandular trichomes on outer phyllaries.


AGROPYRON & BOUTELOUA PUZZLE
>From: Don Gayton, BC Forest Service, Nelson

As a BC and a BEN neophyte, I don't have a contribution but
rather a question.

As a recent prairie emigre, I am puzzled about the distribution
of two grass species, and wonder if anyone has any hypothetical,
plausible, logical or even factual explanation for the
following: why do the Rockies seem to form an absolute western
boundary for blue grama (Bouteloua gracilis) and an absolute
eastern boundary for bluebunch wheatgrass (Agropyron spicatum),
when theoretically their niches should overlap?
