Gareth Shearman, after a lengthy battle with cancer, died, October 14, 2013. He spent much of his last year working to ensure that Victoria Free-Net could continue in his absence.
Gareth was an educator and community network practitioner with over 40 years experience in local, national and international arenas. For much of his career he worked as an educator in the pubic school system and in educational administration. His early involvement with computing was in research in Computer Assisted Instruction and the development of education networks. He was involved with the founding of a number of educational and community computing organizations in BC. He held a BEd degree from the University of British Columbia and an MSc (Ed) degree from Simon Fraser University.
In 1992, he was instrumental in establishing the Victoria Free-Net Association – Canada's first Free-Net – which fostered a sense of electronic community and introduced people to the internet. Gareth was also founding president of Pacific Community Networks Association, president of Telecommunities Canada since 1998, and active in the British Columbia Community Connectivity Cooperative (BC3), the Global Community Networks Partnership (GCNP), and the Internet Corporation for Assigned Names and Numbers (ICANN). These organizations continue their work as supporters of his deep commitment to all aspects of community development and digital inclusion through the uses of information and communications technologies.
He and Mae were co-recipients of an Industry Canada Information Highway Leadership Recognition Award.
Adolf Ceska: It was in the fall of 1991 when Gary Shearman offered to host BEN on the internet system of the Victoria Free-Net Association, which was then in its early stages. BEN # 13 was the first BEN issue sent out from the system Gary set up for me, and I'm sure that some BEN subscribers still remember it. My posting of BEN # 13 created a mail storm, and some BEN subscribers received it up to 70 times. The last time I met Gary was in front of the Victoria Jubilee Hospital cancer clinic: he was leaving from his checkup and I was going to mine. He and his wife Mae meant a lot to me, and we are grateful for Gary's contribution to BEN and to the internet chain in Victoria. For me, Gary is still living in our virtual world.
Key to the Pyrola picta species complex within the Pacific Northwest Physiographic Province
(Because Pyrola crypta is restricted to the Pacific Northwest, our key is
meant to help workers distinguish among members of the P. picta species
complex exclusively within that region.)
1a. Basal rosette of narrow leaves < 1 cm wide and < 1.5 cm long, lacking
petioles and rarely photosynthetic, often hidden beneath
surrounding leaf litter ................ P. aphylla
1b. Basal rosette of leaves at least 1 cm wide and > 1.5 cm long, petiolate,
photosynthetic, lamina not hidden beneath surrounding litter
................................................. 2
2a. Leaves light green to bluish, lacking white mottling along veins,
glaucous leaf surfaces; leaf shape oblong to oblanceolate to
(less commonly) small and orbicular .... P. dentata
2b. Leaves dark green with white mottling along primary and secondary veins,
not bluish or obviously glaucous on leaf surfaces; leaf shape oblong
to obovate ..................... 3
3a. Sepals > 2 mm, floral bracts typically > 4 mm, leaf petioles 1.7–3.9 cm
long ................................... P. crypta
3b. Sepals = 2mm, floral bracts typically < 4 mm, leaf petioles 1.5–2 cm
long ................................... P. picta
Invasive alien plants cost billions of dollars in Canada each year due to
the damage caused to crops, rangeland, and the environment. The costs can be
reduced through knowledge-based management, but … knowledge of invasive
alien plants is limited and comprehensive review of current information is
lacking for many species. Accurate information is vital in the areas of
identification, classification, ecology and management, and review is needed
as a basis for future research.
The first of this series of 10-page reviews was published in the Canadian
Botanical Association Bulletin in Sept. 2011 and one has been published in
all but one bulletin since. The articles are designed to substantially
improve identification as well as providing information on distribution and
ecology in Canada. Information on both damage and beneficial aspects is
provided as well as information on management. Scientific concepts are
explained and anecdotes are included. Selected references favour those
that are more recent (from which earlier work can be traced). These reviews
are based on recent data from publication, information online and from
specimens in collections. The species featured are selected from a list of
prioritized invasive alien plants of Canada which includes 81 species
(Catling & Mitrow 2005).
The reviews are part of a larger project called Major Invasive Alien Plants
of Natural Habitats in Canada. It involves authoritative identification,
databasing of up to 3000 specimens of a particular invasive in each of 30
plant collections across the country (see Table 1). The maps and other
information for the review series are derived from these specimens. The
databases and images are designed to become available online. The assembly
of specimens facilitates their analysis as part of directed research
projects. Answers to specific questions, such as the likelihood of increased
impact and spread, are then based on as much detailed information as
possible. Additionally the needs of clients can be met in a timely manner
with the capability to easily acquire extensive collection-based
information.
The European Common Reed database was first used to predict its impact and
spread in Canada. Then it was made available online at
http://www.gbif.org/dataset/847620ca-f762-11e1-a439-00145eb45e9a by the
Global Biodiversity Information Facility along with mapping, point query and
predictive capabilities attached to a climate model (Catling 2007). It was
accessed more than 50 times a week and during those visits it answered
71,500 questions from 2007 to 2009. Both the reviews, the associated
research, and the cooperatively produced databases and imagery have been
very well received and very successful in efficiently providing accurate
information. This is a good example of the value of biological collections
in Canada and another example of the value of cooperation between them (see
also Mitrow and Catling 2012).

An error occurred in the Oxypolis occidentalis article of BEN #482. The
name Symphyotrichum spathulatum var. spathulatum was based on a
misidentification. This species, mentioned both in the text and in the
captions to the plates, should have been named Symphyotrichum foliaceum
var. apricum (A. Gray) G.L. Nesom. - Hans Roemer
