In the Pacific Northwest from the Willamette River to Puget Sound to Georgia
Straits, on the city streets and public spaces from Portland, Seattle-Tacoma
to Victoria and Vancouver, there is a treasury of temperate shade, flowering
and ornamental trees that surpass in species, variety and quantity most
if not all other regions of North America. Most people would say it's
our cool wet and gentle climate while others, our cultural inheritance
of the 'English disease' Whatever the reasons, there is now, as we begin
the twenty first century, a rich legacy of trees lining our streets and
enhancing our parks that continue to provide a living heritage. They will
bring to our urban environment seasonal beauty and a healthy atmosphere
well into the twenty first century and beyond.
One of the finest example of this living urban forest of shade and ornamental
trees is the Cambie Heritage Boulevard in the City of Vancouver, a three
km long street extending across the midriff of the city with treed verges
and a 10 m wide median arboretum. Vancouver, on the east shore of Georgia
Strait, is British Columbia's largest city and Canada' s most important
Pacific port, and once lay at the heart of the coastal rainforest. The
city still has vestiges of the man modified Douglas-fir, hemlock, western
red cedar forest bordering parts of the city: There are forests like Point
Grey foreshore and Pacific Spirit Park in the west, Burnaby's Central
Park in the east and the world renowned Stanley Park forest to the north.
However, the reputation as one of the world's most beautiful cities is
gained not from these bits of remnant rain forest but from the strong
garden culture and tradition of the English and their love of ornamental
flowering and foliage trees that have been planted and tended on our streets,
avenues, parks and gardens since Vancouver was founded in 1886. Cambie
Street with its attachment to Queen Elizabeth Park's quarry display garden
and crowning arboretum exemplify an urban tree and landscape heritage
unique to Vancouver. Vancouver has 3,200 km of streets. Sixty-five percent
them are treed with over one quarter of a million trees on 2000 km of
streets. Paul Montpellier the City's chief arboriculturist estimates these
trees have a replacement value of half a billion Canadian dollars, a thousand
fold increase in value that these trees produced over the last 20 years.
The forty five block long Cambie Street with median and verges has just
over a 1000 trees. These that add up to a replacement value of 4 million
dollars Canadian. When you combine this with the 1500 trees in the arboretum
in Queen Elizabeth Park that extends onto the Cambie Boulevard median,
the financial value of this living urban amenity forest easily becomes
10 million dollars. This monetary amount in no way represents the real
value of the urban forest landscape in terms of helping to maintain a
healthy environment and providing the enhancement of form, colour and
texture that each individual tree and grouping brings to the beauty of
this garden landscape.
Cambie street and Queen Elizabeth arboretum have
become unique and special in many ways not the least of which is how they
came to be a part of the fabric of Vancouver. In the early 1920s the developing
city occupied only the north half of the Burrard Peninsula with the municipalities
of South Vancouver occupying the Eastern part of the south half. It extended
to the North Arm of the Fraser River with Point Grey municipality taking
up the southwest part of the peninsula. Point Grey bordered the University
Endowment Lands and the University of British Columbia campus at the end
of the peninsula.
In 1926 the St. Louis, Missouri, consulting firm of Harland Bartholomew
& Associates City Planners, Civil Engineers and Landscape Architects was
engaged to prepare a plan that included the city, South Vancouver and
Point Grey. Amalgamation of the three occurred three years later. The
plan for the city prepared by the Bartholomew firm incorporated many if
not all the principles of the English Garden City combined with those
ideals in the US City Beautiful movement. One element in particular of
these combined concepts was for the major streets to have a wide garden
boulevard or landscaped median and tree lined sidewalks on the outer edges
of the roadways on each side. It combines elements of a greenbelt, a park
and a garden all in one.
The Bartholomew Plan called for a framework of these grand and elegant
streets as part of the North-South and East-West street grid pattern on
the 110 km² peninsula. While a few of these planned streets were not built,
those that were, like the east to west 4.2 km King Edward or 25th Avenue,
the north to south Boundary Road with median of 100 Canadian Maples and
the jewel of them all, Cambie Boulevard that formed a South entry to the
City' centre and would create a ribbon of green across the peninsula.
These gave the city a legacy to be found nowhere else to this extent in
any North America city and continues to provide efficient and pleasant
travel amid a landscape environment of visual beauty and quality throughout
the year.
The ornamental trees that are now 50 to 75 years old and make up the
Cambie Heritage Boulevard with those in Queen Elizabeth Park arboretum
include the VIP and Royals planted trees. They are almost all the vision
and work of one man, W. C. (Bill) Livingston, Superintendent of Parks
for Vancouver. Beginning in 1938, when he first started as Park's Foreman
with Vancouver Parks Board and for the next 36 years William (Bill) Livingston
was responsible for creating, building and managing the physical park
system in the city. He oversaw the development of more than thirty of
Vancouver's Parks, beaches, recreation grounds, playing fields, display
gardens and treed streets and boulevards. He died in 1990 leaving us,
in Vancouver and British Columbia a great legacy of parks and recreation
places. Cambie Heritage Boulevard and Queen Elizabeth garden and arboretum
were his special creations.
In 1989 it came to the attention of those who lived in the residential
areas adjoining the Cambie Boulevard that it was being considered as the
route for an overhead rapid transit sky train to connect the Fraser River
delta two island community, now the city of Richmond, with the Vancouver
International Airport, to the existing Expo skytrain line. This overhead
line was built in 1985 for Expo '86. It linked Downtown Vancouver with
the city of New Westminster over top of a disused interurban tramline
right- of - way connecting the two city's downtown areas though the middle
of the City of Burnaby. While Sky Train is an efficient but very expensive
capital cost transit system, the visual impact of the overhead structure
required to carry the tracks and vehicles completely overwhelms all around
it particularly the residential landscape and especially those of Vancouver's
existing 'garden city' single family homes, townhouse and three and four
story apartment buildings. These neighbourhoods are the essence that makes
Vancouver a beautiful, human scaled and liveable city like no other.
Led by Ethel Karmel, an artist who had lived most of
her life in the Cambie area, a group of Vancouver citizens held a series
of rallies in protest of the idea of an overhead skytrain through and
over top of the treed Cambie median. They reasoned there could be no greater
defacement of this landscape though the very centre of the city could
be imagined than to shade destroy completely, maturing trees, landscape
and skyline. Their rallying cry became 'No Skytrain on Cambie'. The group
gathered signatures of over 6000 citizens in support of Cambie Street
becoming a Heritage Landscape. In 1993 their presentation to Vancouver
City Council and Mayor Gordon Campbell, now Provincial Premier, was successful
and Cambie Street boulevard was proclaimed as the first Heritage Landscape
in the city.
In 1994 the group formed the Cambie Heritage Boulevard
Society and Ethel Karmel was elected President. The Society's express
purpose is to provide stewardship and guardianship of this ' Treasury
of Trees' in order that they will stand as a living monument, a reminder
of our city's heritage and will continue to provide year round beauty,
remain an attractive treed entry to the city and help with maintaining
a healthy balance for the environment to the end of the 21st Century and
well beyond.
The Treasury of Trees that go to create this urban street and park landscape
consist of trees that originate from some of the countries and continents
from which many of Vancouver's residents have emigrated from: China, Japan,
Korea, India, Western Europe, Russia, North Africa, the Middle East and
of course eastern and western North America While in arboricultural and
dendrological terms there are 77 species of trees represented in the arboretum
and along Cambie boulevard as well as many horticultural clones and cultivars
of these tree species.
Perhaps
the most spectacularly floriferous trees are the Japanese flowering cherries.
Prunus serrulata 'Pink Perfection'and P. yedonsis, the Yoshino cherry
are the names for these late flowering wide spreading branched trees.
Repeated groups of these on the median are the theme flowering tree for
the Cambie heritage boulevard along with very horizontal branching double-white
'Shirofugen' and the vase shaped ice-cream pink 'Kwanzan'. A grove of
the equally floriferous, early flowering open vase shaped branching roundheaded
Japanese cherry is called. P. yedonsis 'Akebono' the Daybreak cherry that
edges the north slope of the Queen Elizabeth Park arboretum. In late March
and early April this pink cloud of pink daybreak cherry can be seen directly
in front as you drive southbound up Cambie street between 37th Avenue
and Marine Drive. These cherries are perhaps some of the very best of
Vancouver's 26 varieties of Chinese, Japanese and Korean Oriental cherries
grown along the streets and in parks in the city. The days are cloudy
and the temperature is cool so the cherry blossoms fade little and last
through several weeks Like the people from these Asian countries they
like it and prosper here in Vancouver.
The
magnificence of living plants is represented on the Cambie Heritage by
the 'Giant Redwood' or 'Bigtree', Sequoiadendron giganteum. from the Sierra
Nevada Mountains of California. When they were planted in 1938 it began
the tree legacy for Cambie. This eight block long median combines the
'Bigtrees or Giant Sequoias with the rare golden yellow leaved selection
of the English elm, called. Ulmus procera ' Vanhoutei'. Van Houte was
the Belgian nurseryman who selected this slow growing colourful round
headed tree with the golden leaves some time in the latter part of the
19th century. The bright gold leaves of this elm contrast with the perfect
cones of dark blue green foliage of the 'Bigtrees'. Planted in the 1936
by parks gardener, Robert Guthrie, deceased, these friendly giants are
guardians at the entrance Vancouver's downtown and are now approaching
200 ft (60m) in height, almost matching the height of the new residential
towers being built in the downtown.
In the Cambie median nearby to the Bigtrees is a single specimen of a
tree that is equally magnificent and makes up for a smaller stature by
the graceful sweep, spread and weep of its branches. It is the Deodara
cedar from the India-Nepal Himalayas: Cedrus deodara. The species epithet
translates from Hindi as beautiful tree. which indeed this evergreen is,
and perhaps also ranks as the most graceful of all the conifers. Both
Deodara cedar and the stiffer Blue Atlas Cedar C. altlantica glauca, from
North Africa's Atlas mountains grow and look so well in Vancouver, most
people believe they are natives.
In the adjoining Queen Elizabeth park arboretum, equally magnificent
but more picturesque than graceful, are the native Douglas-firs scattered
around with the other conifers. There is also a large stand of the coastal
variety of this Pacific Northwest timber tree that Archibald Menzies the
Surgeon Botanist with Captain Vancouver found here over 200 years ago.
David Douglas introduced this conifer as an ornamental to the gardens
and parks of England and Scotland thirty years after Menzies used it to
make the 'Spruce beer' that kept Capt Vancouver's ship's crews free of
scurvy throughout their three years in these waters. This home grown grove
of Douglas-fir, Pseudotsuga menziesii in the Queen Elizabeth arboretum
was planted in 1938 to commemorate an organization of boys called Junior
Forest Wardens,.whose role was to learn and practice forest fire protection.
A few years later most of the older boys went off to fight in World War
II and the corps set up protect our coastal forests and who wore red shirts
and green forage caps was disbanded.
Cambie boulevard and the arboretum is unique in using two westcoast
conifers, the Falsecypress' as ornamentals, Chamaecyparis nootkatensis
and many varieties of Lawson's 'cypress. C. lawsoniana . They are scattered
in threes all along the central median and in groves in the arboretum.
Nootka Falsecypress (Yellow Cedar or Alaska Cedar are the forestry names),
on the Cambie Median is as far as is known is the first use of this widely
distributed Pacific Northwest native, with the most distinct ammonia fragrance,
in an urban street setting. Not quite as elegant as Deodara cedar and
slower growing they add with the 'Aurea' form of Western Arborvitae (Western
redcedar is the timber name), Thuya plicata present year round, great
mounds of golden green colour and repetition along the median.
Lawson's 'cypress varieties grace the Cambie median and the well drained
slopes of the arboretum. This conifer is native to a 200 mile long strip
of coastal mountain area in southern Oregon and Northern California. Seed
sent by David Douglas to his friend James Lawson in Scotland quickly found
its way into the Lawson family nursery. Genetically unstable many juvenile
foliage seedlings were introduced as a separate species called Retinospera
. The many forms, colours and shapes were raised by the Lawson nursery
and others in England, there are some 150 named varieties. Most rapidly
outgrew this dwarf conifer size and juvenile foliage, some to grow into
graceful 30 to40 meter high trees. There are several on the Cambie median
that are tall and extremely narrow with golden foliage and others with
glaucus (bluish) foliage. Each tree has a wide spreading petticoat of
juvenile foliage at ground level. They are the variety C. lawsoniana "Stewarti',
and C. lawsoniana 'glauca', the Golden and Blue Lawson's ' cypress. In
the arboretum a grove of C. lawsoniana 'Fletcheri', makes a lovely group
on the grassed slope, viewed from below. We in Vancouver rarely if ever
water our public park and school lawn areas, this includes the Cambie
Street and King Edward medians. To a large extent this lack of summer
watering prevents the demise of these conifers from the phytophera fungus
that kills the tree's cambian. It is triggered when these trees receive
summer watering; the Hinoki Falsecypress C. obtusa varieties are not affected.
This Japanese species' aurea variety is alternated with the dogwoods along
several blocks of Cambie Heritage Boulevard.
Cambie Heritage Boulevard's best kept secret and legacy are these dogwoods.
Most North American authorities recommend against using dogwoods as street
trees especially when grown on standards as these thin barked edge of
the forest trees usually need to have their trunks shaded. This is not
the case along Cambie Heritage boulevard however. There are three species
of Cornus, along with a variegated leaved and two pink flowered forms
as well as a hybrid of two of the dogwood species. They are all planted
in blocks along Cambie street not in the centre median but along the roadsides
between street and sidewalks. Prominent along several blocks is the variegated
leaved Pacific Dogwood, Cornus nuttallii 'Goldspot' . Goldspot dogwood
with splotches of gold on the leaves was found growing in the wild and
introduced by the Pioneer coastal British Columbia nurseryman and rosarian
Henry M. Eddie.
The Pacific Dogwood, Cornus. nuttallii, British Columbia's provincial
flower is also planted along Cambie. Most years they and 'Goldspot' flower
twice:, a big show in spring completely clothing the trees in white, sometimes
before the leaves and with a lesser amount of bloom again in August-September
.The 6 large white bracts surround a 'raspberry' of seeds. that turn red
and decorate the summer green, pink and rust fall leaves. The 'red raspberries'
of seeds and the rich mahogany of autumn leaves and the pointed glistening
white bracts of selected forms of the Korean Dogwood, C. kousa out performs
the native dogwoods, but does not compete in time, as they follow on with
their floral display in April and May along the street. The eastern US.
dogwood C .florida and a selection named Cherokee Princess with pink floral
bracts are also featured on the Cambie street roadsides.
In 1986 to honour the first hundred years of Vancouver as a city, a tree
was selected to officially honour Vancouver's centennial. It is the hybrid
dogwood, bred and introduced by the afore mentioned local nurseryman H
.M. Eddie. It is a cross between the Pacific dogwood and C. florida ,with
the name 'Eddie's White Wonder' ; and indeed it is, and comely too. Since
1990 there have been plantings of 'Eddie's White Wonder' along streets,
on School grounds in the city and in particular on Cambie Heritage Boulevard's
roadsides and median It is more floriferous, consistently covered with
blossom, with larger white floral bracts than the Pacific Dogwood. The
tree has a stronger constitution, with hybrid vigour and a richer more
brilliant fall colour: 'Eddies White Wonder' dogwood is ideally suited
to Vancouver's climate.
At 33rd Avenue, Cambie south bound takes a wide curve to sweep up and
around the edge of the park's arboretum. As one turns off Cambie at the
crest and waits at the gap in the median before crossing to enter into
Queen Elizabeth Park's lower road and arboretum drive, there is on the
rise ahead, a grove of fine needled conifers These are the Dawn Redwood,
Metasequoia glypstostroboides, named first from the fossil of it and before
it was found in 1946, 'alive and well' in a 40 by 100 km area in Northwestern
Hupeh province in Central China.. Seedlings were subsequently introduced
by the University of California Botanical Gardens and the Arnold arboretum
to arboretums, botanical gardens and parks departments around the world.
It became the most widely distributed tree in the twentieth century. Metasequoia
have clean bright- green new needles in spring that turn a rich milk chocolate
brown in late November. This tree is beginning to achieve majestic proportions
in the arboretum and along several streets in the city. Again Vancouver
has led the way in using this tree to enhance an urban street. The Dawn
Redwoods on Kerr street and in the Queen Elizabeth arboretum are now 50
years old.
The Majesty of trees at the South end of Cambie Heritage Boulevard is
taken by a little known, or rarely used ornamentally, of the North American
white oaks, Quercus macrocarpa. Its native range extends into Canada's
southern Manitoba areas of the Red and Assiniboine Rivers and up into
the boreal forest area between lake Winnipeg and lake Winnipegosis.
In David Douglas' 1823 monograph on the 26 North American Oaks, prepared
after his trip to the Eastern US and Upper Canada, for Joseph Sabine,
RHS Secretary, Douglas quotes Pursh: "The clusters of its (Q. macrocarpa)
large acorns with their mossy fringed cups, and the beauty of its deeply
lobed leaves, give this tree a singularly graceful aspect." No one seems
to have commented on it since. Their majestic nature after only 40 years
shows promise of surpassing the largest in the wild, said to grow in the
Allegheny mountains of eastern United States. Another best kept secret
of the arboretum in the grove bordering the Cambie Heritage Boulevard
are the species of oaks planted there. The oaks were the favourite tree
of the late Vancouver Parks Superintendent Bill Livingston who created
the park and arboretum . It is hoped that this grove can be named in his
honour and dedicated to his memory.
The front lawn conifer of the suburban garden in Canada's colder climate
areas has traditionally been selected from the more glaucous forms of
the Colorado Blue Spruce, Picea pungens glauca. Almost always misnamed
as Koster's Blue Spruce, that is a blue needled semi-weeping grafted form
from Europe. Although there are some fine spruce in the Queen Elizabeth
Park arboretum the Colorado blue spruce does not do well in Vancouver's
calm and benign climate that favours a insect feeding on the new needles
to give the tree an unkempt appearance. Several successive annual attacks
will kill the tree. Vancouver is a pesticide free city and while there
is one or two blue Spruce on the median there is another species of spruce
there that is not attacked. This species of spruce now all along the median
is the more graceful of the spruces, the Serbian , Picea omorika.; they
are the newest addition. To accompany this conifer the arborists at the
Vancouver Parks Department have added the pure white floriferous Kobus
Magnolia, Magnolia kobus, the Japanese Snowbell, Styrax japonica and the
Paperback Maple, Acer griseum. These garden scaled comely trees have stepped
into the public realm of the median to give a front garden continuum to
Cambie Heritage Boulevard signing it as the entry to garden city Vancouver.
