“No two forests are alike. They are like art galleries: they all have pictures, but they don’t have the same pictures….So the first question is Why?” We would expect each region to contain plants that are adapted to it – for if they were not, then they would soon be ousted by those that are. But why does each region have its own characteristic suite of native species?” ~Tudge, Colin. Page 278
“There’s another kind of puzzle, too. …The farther you travel from the equator, the more the variety falls off.” ~Tudge, Colin. Page 279
Saskatchewan has a native ecosystem called the Aspen parkland. Why the Aspen? Fire, especially grassland fires have been known by the first nations, and the pioneer homesteaders. Grassland fires can be carried by the wind, and the range of the fire can spread out in front of the wind for hundreds of miles and miles.
Well, according to Colin Tudge, :The Aspen has long lateral roots, which, at intervals, send up suckers that grow into entire new trees. …if it [fire] occurs in spring or summer it will kill the aspens along with everything else, because it burns the organic matter within the ground, including the aspen’s trailing roots. But if fire strikes in winter when the ground is frozen, or in spring when it is still wet, the roots survive. Then the suckers rapidly grow up to form new trees-rapidly because they already have a fast, established root system to draw on. “~Tudge, Colin. Page 309

“St. Barbe’s unique capacity to pass on his enthusiasm to others. . . Many foresters all over the world found their vocations as a result of hearing ‘The Man of the Trees’ speak. I certainly did, but his impact has been much wider than that. Through his global lecture tours, St. Barbe has made millions of people aware of the importance of trees and forests to our planet.” Allan Grainger
“The science of forestry arose from the recognition of a universal need. It embodies the spirit of service to mankind in attempting to provide a means of supplying forever a necessity of life and, in addition, ministering to man’s aesthetic tastes and recreational interests. Besides, the spiritual side of human nature needs the refreshing inspiration which comes from trees and woodlands. If a nation saves its trees, the trees will save the nation. And nations as well as tribes may be brought together in this great movement, based on the ideal of beautifying the world by the cultivation of one of God’s loveliest creatures – the tree.” ~ Richard St. Barbe Baker.
“I believe in the Oneness of Mankind and all living things and the interdependence of each and all.”Richard St. Barbe Baker
“I believed that God has lent us the Earth. It belongs as much to those who come after us as to us, and it ill behooves us by anything we do or neglect, to deprive them of benefits which are in our power to bequeath.” Richard St. Barbe Baker
Trembling Aspen grove [in 2016] Richard St. Barbe Baker Afforestation Area Saskatoon, Saskatchewan, CA
It was the summer of 2017, did you see it?
The Populus tremuloides (Trembling Aspen or Quaking Aspen) groves were struggling, and suffering tremendously. The defoliation caused by the Tent Caterpillar Malacosoma disstria was so severe, that combined with the severe drought, the vigour and vitality of the Aspen Trees was greatly reduced. 2017 saw the fourth year of the Tent Caterpillar infestation in Saskatoon. When healthy trees that are completely stripped of their leaves are able to refoliate their leaves after the caterpillars have feasted, however the second growth is smaller and, indeed, may be inadequate to compensate for the damage caused. The attack of the caterpillars may even kill the top of the tree, side branches and even the whole tree may expire with multi-years of excessive defoliation.

James J. Worrall et al, explains that drought, tent caterpillars and other factors contribute to the decline of Trembling Aspens. Severe drought precipitates the most drastic decline, followed by foliage stripped by tent caterpillars year after year. Aspen stands cannot recover from such shocks to the system on a multiyear basis, without relief.

“It’s almost as if nature has forgotten how to rain in parts of Saskatchewan,[9]” said David Phillips, senior Climatologist with Environment Canada, who goes on to explain that, “It really does show you the kind of climate you have: a desert — dry, semi-arid, almost like Pheonix, Ariz. — where the days can be very hot, and in this case bone dry and not a cloud in the sky. All that heat from the day radiates into space … It left the nights relatively cool.[2]” Saskatoon received only 243.6 millimetres [9.6 inches] of precipitation, bringing 2017 into the top five driest years for the city.
Not only was 2017 setting records for the driest years in history books, the problem for the Trembling Aspen was compounded as being the worst for the Tent Caterpillar plague. “We’re in a boom period for the tent caterpillar,” [10] ” said Tyler Wist, Field crop entomologist for Agriculture and AgriFood Canada. The tent caterpillar has a natural predator in birds, as well as the eggs of the sarcophagid fly.
Effects on overall health of aspen. Repeated defoliation by forest tent caterpillar may not allow trees to recover to a normal state of health, which can lead to decline. ~ Natural Resources Canada“

Following two or more years of severe feeding there is a general decline in tree health, including twig and branch dieback. After three or four consecutive years of being stripped of their leaves trees can be weakened and may be more susceptible to insects, such as wood borers, and stem disease. Following forest tent caterpillar infestations the incidence of hypoxylon canker, a fungal stem disease, may increase and cause extensive damage in aspen forests. “~ Forestry Branch
Late spring frosts kill buds leading to early, mass larval stravation. Alberta Government.
“When populations are low, the egg masses on small plants can be removed by hand and destroyed between July and the following spring. Hand picking can inflict significant larval mortality.
Destruction of occupied tents by hand or with a brush leads to colony collapse. Pruning to remove egg masses, tents, or groups of larvae must be done sparingly to avoid injuring the plant. Using fire to accomplish this is not recommended as it damages the plant more than the defoliation.”~Forest Health Protection
The trembling aspen is known to grow as a clonal colony in which the stems [trunks] arise from one huge conjoined root system. Whereas the tree stems of the Trembling Aspen may be determined by its tree rings, the roots may be much older than that of the tree trunks. In the semi-arid regions of the west, Trembling Aspen are more likely to establish new trees via suckering from an established root system rather than from seed. It is intriguing to learn that the Aspen Tree is really only a small fraction of a much larger organism. Malcolm F. Squires reports that clones of Aspens may have sprouted following the Pleistocene era after the retreat of the great ice age, creating the oldest organisms in the world. One can tell one Aspen clone growth from another, as leaves will emerge in the spring and turn to yellow in the fall in the same clone, and a neighbouring clone will exhibit a different time scale.
If a clone of Aspen trees from the same root is even aged, and has thrived in near to full sunlight, is severely attacked and stripped of its leaves by tent caterpillars causing some of the Aspen trees to die back. The Aspen roots, in some cases, if the soil is healthy, be able to regenerate from suckers. Young saplings will rise from the roots in the openings, or these young trees may take advantage of thin crowns. The Aspen stand will show this uneven age structure, until the remaining tree trunks die off, and all the tree stems become even aged.
“Jack Schultz, a Pennsylvania State University entomologist… discovered that aspens react chemically to insect attack. Soon after the caterpillar start chewing, the trees’ remaining leaves produce bitter-tasting phenol compounds to discourage further eating” [5]
In 2017, it was seen that the Trembling Aspen stands lost their leaves, and a second smaller growth was seen coming late in the summer season. Watch if and how the Aspen stand recovers in 2018. It will be also interesting to note if 2018 again succumbs to a double whammy of drought and tent caterpillar. Saskatchewan is a province of cyclical weather alternating between drought and years with a high water table [perhaps even flooding]. The tent caterpillars well, their cycle lasts between three to seven years, and they normally re-occur in 15-20 year intervals.
The round leaves turning golden in the autumn months, quivering, and catching the light as the breeze tosses the golden discs this way and that, give the Trembling Aspen the appearance of being a “Money Tree” as its branches dance in gold.
Silviculture is the practice of controlling the establishment, growth, composition, health, and quality of forests to meet diverse needs and values. The name comes from the Latin silvi- (forest) + culture (as in growing). Richard St. Barbe Baker attended Cambridge University, graduating as a silviculturist.

“This generation may either be the last to exist in any semblance of a civilised world or that it will be the first to have the vision, the bearing and the greatness to say, ‘I will have nothing to do with this destruction of life, I will play no part in this devastation of the land, I am determined to live and work for peaceful construction for I am morally responsible for the world of today and the generations of tomorrow.'”
