Worth Preserving

The history of Canada is staged
against a forest background. In fact, forests have had great
influence on the progress and welfare of mankind in every
land and in all ages. Without wood, history would be a very
different story.
Take Canada today. Of all the wealth created by our basic
sources of production - agriculture, forests, fisheries, trapping
and mining - the forests produce one third, or, to be wholly
accurate, 31 per cent. On these basic industries rests Canada's
trade and commerce.
In countries which border on the sea, forests were the foundation
of shipbuilding industries, maritime expansion and naval prowess.
In our early history the forests on our eastern seaboard played
a significant part. They were so favourably located with reference
to both the sea and rivers that our colonists built a thrifty
trade overseas. Here was the forest primeval of Longfellow's
Evangeline. Nova Scotian ships were known in every
port of the world, and by 1878 Canada was fourth among the
shipowning nations. That era passed away with the coming of
steel ships, but the worth of our maritime slopes for growing
trees has not died. Nearly eighty per cent of the land area
of Nova Scotia is unfit for agriculture, but is well suited
for the production of timber crops.
The job our maritimers have to do is one of conservation,
wise management, and development. Fifteen hundred miles westward
begin the prairies, where the task is entirely different.
It is not a matter of managing a forest or woodlot already
there, but of attempting to establish a grove of trees where
none exists.
The development of prairie farm tree growth has been phenomenal.
The government policy of tree distribution, started in 1901
as an experiment, has grown until by 1946 the output from
nursery stations had totalled 200 million trees.
It is not many years since the western plains farmer derided
the idea of growing trees, but already the benefits of woodlots
and shelter belts are widely acknowledged. Twentyfive
years ago one seldom saw trees around farm buildings, there
were no vegetable patches or flower gardens, and the sight
of a few willows living their precarious life near a gully
or at the bottom of a coulee was a relief to dustfilled
eyes.
Today, trees give shelter to crops, buildings and livestock.
They collect and hold the snow, preventing it from banking
up around buildings, and they release it slowly in spring
so that more of its precious moisture is fed into the earth.
They break the force of hot winds in summer, slowing down
evaporation. They give shelter for gardens, and make living
more pleasant.
Use of Land
This digression was made to indicate that forestry is practicable,
paying and desirable in all parts of Canada, from the natural
home of trees on the Atlantic and Pacific slopes to the grasslands
of the Prairies. But not all land is suitable for trees, or
for the same kind of trees.
Forestry represents one of the three major ways of using
land. The others are cropping and pasture. Generally, woodland,
grass land and desert divide the surface of the earth among
them, and between them there is constant conflict. The grass
lands are forever attempting to encroach upon the woodlands,
often with the assistance of men bent upon extending their
farms. The desert is always trying to encroach upon the grass
land, an attempt in which it has been helped by men: in the
past, unwittingly, but in these days of widespread knowledge
about wind and water erosion, by men with their eyes wide
open.
In Old Ontario, according to the report of the Royal Commission
on Forestry, 1947, forest cover has shrunk to 9.7 per cent.
Groups which have studied the question estimate that up to
8,000 square miles, or 5,120,000 acres, of waste land should
be returned to forests; the Commission itself is convinced
that at least two and a half million acres of Old Ontario
might profitably be reforested.
There is no overall recipe, no rule of thumb, as to where
trees should be planted or not planted. Every scheme needs
to be looked at individually, and the longtime results
as well as the immediate effects should be assessed. The draining
of marshes, for example, may be good or bad. Holland Marsh
in Ontario did not involve water storage and the reclaimed
land is being put to good use; draining of Florida swamp,
on the other hand, has upset the balance of nature as well
as the bank balances of those who did it. Not only expert
advice but common sense is needed.
Different parts of the country demand different trees and
different care. A wellkept forest in British Columbia
will look quite different from one in New Brunswick, yet each
may be perfect for its location. The trees are suited to the
soil and climate, and, so far as may be possible, to the requirements
of the owner.
There are, however, certain qualities they will have in
common. Poor or surplus trees have been thinned out to give
the good ones room. There are no overripe trees, past
their best growing years, no diseased or damaged trees, no
very branchy or badly shaped trees. The forest floor is covered
with needles, leaves, twigs and small branches, so that the
soil absorbs the large amounts of water trees need and prevents
erosion. Grazing animals and fire are kept out. These are
the marks of a good forest anywhere.
Age, Growth and Size
There are two dangers facing the planner of a woodlot or
small forest: that he may expect returns too quickly, and
be disappointed, or that he may decide the time needed for
growth is too long, and the results not worth his best effort.
It is true that trees do not grow to maturity with the speed
of radishes or nasturtiums. With some trees one must think
in terms of half centuries and centuries and it may be said
as an aside that countries with the vision and courage to
do so will benefit because children now at school will live
to see the culmination of such thinking.
If you wish to be remembered, said the English essayist
in Dreamthorp, "better plant a tree than build a city
or strike a medal - it will outlast both." In England there
are oaks whose acorns were forming that June day when King
John signed Magna Charta at Runnymede, and a few years ago
there still existed the Newland, Gloucester, oak mentioned
in the Domesday Book which was compiled in A.D. 1080-1086.
It is claimed that sequoias of California have rings going
back to 1305 B.C. And in Mexico there is a cypress said to
be 3,000 to 5,000 years old.
That is one side of the shield, the exotic side which has
not much material significance for the Canadian farmer intent
upon growing fence posts, firewood or merchantable timber.
He will be immediately interested in the fact that in its
natural home east of the Rockies a spruce forest reaches maturity
in 60 to 100 years and balsam reaches merchantable size in
40 years. These two, which account for 86 per cent of the
wood used by pulp and paper mills, make up by far the largest
part of our softwood forest.
Here is a table based on the average of hundreds of trees
of each kind growing in plantations on the nursery station
at Indian Head, Sask. It shows the age of the trees and the
height attained at that age.

Forests Store Water
Over thousands of square miles of North America watersheds
have been deforested and overgrazed, declares William Vogt
in Road to Survival. Thousands of silted stockponds,
power and drinking water reservoirs, and miles of muddy flooding
rivers show the effect of this devegetation.
Although forests intercept rain and, by promoting evaporation
before the water reaches the ground, reduce the amount of
immediately available water, they more than make up for it
in other ways. Research findings show that the residual water
is almost all usable. Remove the forest, and the runoff
becomes flood flow, usually wasted and always laden with valuable
topsoil.
The trees, their roots, and the humus of the forest floor
act as great sponges. The result is a tendency to equalize
stream flow, to reduce the gap between high and low water
stages, and to lessen the seriousness of floods. This is of
importance not only to adjacent farms, but to distant centres
of industry which depend upon a steady flow of water in the
rivers to supply their electricity.
This water control we have been talking about is managed
mostly by the great forests which mantle the mountain ranges
and the highlands which are the headwaters of our great rivers,
but even the small farm woodlot has its part to play.
One farm woodland has little effect on the whole floodcontrol
problem, but a little patch of woods here, a larger one on
another farm, and so on for thousands and thousands of farms
- why, even today these farm woodlots amount to 34,792 square
miles, and that is important acreage in any country's water
conservation programme.
Erosion Control
One has only to read Mr. Shepard's instructive book Food
or Famine, with its references to the challenge of erosion,
to realize how among some people - and is it so very different
among ourselves? - the destructive process has reached vast
proportions "rooted in ignorance of the ways of nature and
in greed and shortsightedness in using nature's bounty."
Studies show that the principal causes of soil erosion are
the removal of timber, burningover of land, breaking
up the vegetative soil cover, cultivation of crops on steep
slopes, and overgrazing of pasture land. As Zimmerman
puts it: First the axe, then the plough, then the rain, then
erosion, finally the desert.
When the British tanks stormed into Tunis in 1943 they churned
up the dust of Carthage, the great city of a million people
built by the Phoenicians in 850 B.C., the wealthiest city
of antiquity. The people of Carthage in 393 B.C., when their
city had been standing just as long as from Columbus' discovery
of America to this present year, would have mocked anyone
who told them their buildings would be buried in sand, merely
a nuisance to be fought over.
We in Canada need not fear that fate for our farmlands and
cities, because we have the book of milleniums of experience
open before us, and we have a hard practical reminder when
paying taxes to provide relief for countries which are unable
to grow food on their desolate land.
Conservation
Leading authorities say that at least ten to twenty per
cent of any agricultural section of land should be supporting
forest growth or woodland. It is the job of conservation people
to reach that minimum.
We have made progress in many directions, notably in forest
fire protection, in research, and here and there in private
forest management. But the sense of need is not yet widespread.
A recent financial newspaper's special section of 24 pages
dealing with forests and pulp and paper pushed the single
article on conservation to the back page.
At last year's Summer School in Banff the naturalist Dan
McCowan told of Alberta's plan for a band of trees to be set
out and preserved in the foothills from Montana to the northern
limit of the province. The glaciers are melting rapidly, and
the great undertaking to conserve water has farreaching
objectives. A board representing both the Dominion and Alberta
has been set up to obtain and maintain the greatest possible
flow of water in the Saskatchewan River and its tributaries.
We are learning that conservation is not merely prohibition.
It has a broader scope than that. It means wise use, which
benefits us at once, as well as purposeful development, which
makes things secure for the future. It means orderly handling
of woodland and cropland, which profits us today, as well
as sustained regulation, which assures us of supplies of wood
and food and water in years to come.
Public Cooperation
Any conservation plan needs public cooperation. It
is only a waste of time to try to parcel out the blame for
conditions as they are. Science and our people can stop the
waste, replenish the woods, and place our water and timber
supply on a perpetual basis.
We are not crying over spilt milk, but trying to learn a
lesson, when we recall the hive of woodworking industry that
used to be eastern America. The income loss from deforestation
has been tremendous. Some parts of the lumber business literally
sawed off the limb on which they were sitting. They left big
stretches of Canada and the United States a ghastly epitaph
of human effort misapplied.
Overcutting did not merely exhaust timber. It destroyed
the complex balance of vegetation and soil.
Official Protection
Public cooperation will be more effective when it
works with and through officials responsible for jobs which
require expert handling.
Forest wardens are not officers with shotguns keeping people
out of the woods, nor are they "tree doctors" who hasten out
to treat sick acorns. They are trained men who preserve whole
forests from disease and death. The most important principle
in the field of forest protection is that preventing the start
of a destructive agent is far more effective than control
efforts after the damage is under way.
This is why careless people are unwelcome in Canada's forests.
A Nicaraguan proverb says: "One man in one day with one match
can clear a hundred acres."
Forest fires start as the result of what people do or do
not do. Human carelessness, indifference and ignorance are
to blame for all but the very few fires started by lightning
or other natural causes.
Fires, though the most spectacular, are not the only menace
to forests. The peaceful appearance of woodland is deceiving.
The trees forage with their roots for water and food, and
gather sunshine with their leaves. Insects attack them from
their roots to the tips of their twigs, all through their
lifetime. Disease runs through millions of acres with epidemic
speed and destruction.
In a managed forest or woodlot space is given the trees
by thinning. Foresters attempt to control insects by encouraging
their natural enemies such as parasites and predators, or
by using insecticides. Diseases are fought by destroying whatever
is causing the disease, by protecting trees by fungicides,
and by breeding trees that are immune to particular diseases.
More and more the provinces are providing the service of
foresters to help woodlot owners and small forest managers.
Says M. Roch Delisle, Director of the Forestry Extension Bureau,
Quebec: "A competent and active forester who takes the trouble
of going into the woods with the owner will achieve in one
year more silvicultural practice on woodlands than will in
ten years all radio talks, bulletins and press articles."
Widening Markets
It is worthwhile for the man who owns trees to take care
of them and provide for a future yield, because the market
for wood is expanding.
This is realized by the big user of forest trees, the Canadian
pulp and paper industry, which is increasingly concerned with
the future of the forests it operates and of the forests as
a whole. Annually, the industry spends many millions of dollars
in developing improved forest management methods. Some years
ago it adopted, declared and is now implementing a forest
policy of perpetual yield and increasing output from its woodlands.
As a result of careful management, there are forests which
have been cut over from time to time for 100 years and are
still giving fine yields of wood.
Everyone knows that this industry is Canada's most powerful
collector of United States dollars through export of products.
In 1947 the industry took pulpwood valued at $203 million
and converted it into products having a gross value of $706
million, thus increasing the value of the wood it used by
3½ times. It obtained its wood from the following sources:
| From farmers and other small holdings: |
20 |
per |
cent |
| Other purchases, including sawmill waste |
10 |
" |
" |
| Cut from owned or leased limits |
70 |
" |
" |
There are, of course, many other manufactures which include
wood as their chief raw material, and it would surprise any
of us to follow a tree from the forest to its final product
and to see the work that is supplied in its harvest and fabrication.
The forest provides employment regularly for many people.
One third of all the wood cut in Canada each year comes
from farm woodlots, according to Mr. E. S. Richards in his
booklet Farm Woodlots in Eastern Canada. The average
value is low, however, because most of the wood from farms
is sold or used as fuel, while most of that from other sources
commands higher prices as sawlogs or pulpwood.
Local woodmanufacturing industries could be successful
if they were assured of a continuous supply of good quality
wood such as could be raised if wellkept woodlots were
operated on a sustained yield basis. The furniture industry,
which grew up in Ontario because of the hardwood forests originally
growing there, now depends to a large extent on imports, while
hickory and white ash for the handle industry come from the
United States. The trees which were the foundation of these
and other industries grew and can be grown again close to
the factories.
Forest Education
It is necessary that we should learn forest facts, not forest
fancies. The poet who wrote: "Woodman, spare that tree! Touch
not a single bough! In youth it sheltered me, And I'll protect
it now," was being merely sentimental, but his opening words
are often quoted in serious society today. The "Woodman, spare
that tree" approach to conservation is wrong, provided the
tree is mature and can be put to effective use.
Educational programmes, both in public and high schools
and in adult courses, should tell convincingly about the advantages
of good forest management. One does not need to be a Johnny
Appleseed, planting apple pips all over the place, in order
to be a good forest conservationist. In fact, a man who carries
a pocketful of acorns to plant along the road when he goes
for a walk is likely setting out groves of trouble for future
generations. There are places to plant, and not to plant,
trees, and we need the right trees in the right places.
Teachers might benefit by more intensive training in normal
schools, not in the techniques of forestry and in tree recognition,
but in the practical and necessary points about preservation
of what forests we have and the need for more trees.
Through the 4H clubs, a whole generation in Quebec
is approaching maturity with sound training in forestry and
small woodlot management.
Out in British Columbia a little while ago Judith Robins
and Jimmy Jones were the first to receive seedling trees and
a certificate when the Western Branch of the Canadian Pulp
and Paper Association supplied thousands of seedlings to school
children. The certificate is an elementary lesson in forest
conservation for all of us: "These Trees are Like Little People.
Be Kind to Little Trees. A little tree has been given to you
to plant carefully where it will grow in your own garden.
Protect it, water it, and guard it from fire so that it will
grow tall and strong. It should inspire you through all the
years of your life."
And, Finally:
Being in the lumber or firewood business is not the only
reason for growing and protecting trees. They are much more
than columns of wood; they are living creatures of a great
creation. They breathe, eat, drink, grow, reproduce, work
and rest.
In some parts of Sumatra the natives believe that certain
trees are the residences of spirits of the woods. It is not
hard to understand that a thing so stately as a tree which
grows so much bigger and becomes so much older than men should
win the reverence of early mankind. We do not have to go that
far, but a little of it would be a good thing, economically,
aesthetically, and for our preservation.
Willa Cather, who remembered the lone peach tree in the
church garden atop Acoma, near the Enchanted Mesa in the New
Mexico desert, and came home to write Death Comes for the
Archbishop around it, said this: "I like trees because
they seem more resigned to the way they have to live than
other things do." That appears to throw the burden of their
protection squarely on our shoulders. These prisoners, chained
down by their roots, powerless to run from storms and fire,
have only men to stave off disaster. In return, they form
the basic structure in men's lives. As the Old Testament prophet
said: "The tree of the field is man's life."
There is another virtue about trees, not yet mentioned.
Some, as we have seen, carry our thoughts back to olden times
- to the stately Bluenose ships which sailed out of our harbours
for ports in all the world; to Maisonneuve, setting up his
cross on Mount Royal; to the timber stockade of Fort Garry,
and to the sea of trees that stretched between Alexander Mackenzie
and the Pacific when he first glimpsed the western shore of
Canada.
But in addition trees project us into the future. When we
plant them and protect them we know we are performing acts
the issues of which will long outlast us. Our maples and pines
and elms and balsam are just seedlings today, but the oak
seedlings which were tender plants when Cartier first strode
through a Canadian forest - what have they not seen of Canada's
emergence from wilderness to metropolis, of her development
from the home of aborigines to a leader in civilization? What
may not our seedlings see?
