Some will choose to embark on walks making every day some new acquaintance with Nature. Come walk in nature with a sense of greater space and freedom. This suggests besides, that the universe is not rough-hewn, but perfect in its details. Nature will bear the closest inspection; she invites us to lay our eye level with the smallest leaf, and take an insect view of its plain. Come walk in the woods, become reminded of that a wise purveyor has been there before. Perhaps the most delicate experience is typified there. Become awe struck with the pleasing friendships and unanimities of nature, as when the lichen on the trees takes the form of their leaves. In the most stupendous scenes see the delicate and fragile features, as slight wreaths of vapor, dewlines, feathery sprays, which suggest a high refinement, a noble blood and breeding, as it were. It is not hard to account for elves and fairies; they represent this light grace, this ethereal gentility. Bring a spray from the wood, or a crystal from the brook, and place it on the mantel, and all store boughten household ornaments will seem plebeian beside its nobler fashion and bearing. It will wave superior there, as if used to a more refined and polished circle. It has a salute and a response to all nature’s enthusiasm and heroism.

National Forest Week brings attention to our forests and trees from coast to coast across Canada. Our forests and trees provide habitats for wildlife, insects, polllinator species, birds and so much more! What is the ‘triple environmental emergency we are facing?
1. Loss of biodiversity 2. Climate change 3. Out of control pollution.
Out of control pollution. Our native biodiversity needs wild spaces, food and homes such as trees and forests provide in which to thrive. Forests, tree planting, and forest conservation initiatives are nature-based solutions towards climate action. Pollution, pesticides, herbicides are escalating the extinction events. Creating safe, organic forest spaces is a large step to halt and slow down the silent sixth mass extinction event of invertebrates, the planet’s bird food on wings. Ornithologists and botanists have noticed that the songbird, and raptor populations have declined by a staggering 48%. The monitored wildlife populations are reduced by a catastrophic 68%. A loss of forests and habitats have caused over 2/3 of our animal populations to totally disappear.
Richard St. Barbe Baker said it this way, “If a person loses one third of his or her skin, the person will die; if a tree loses a third of its bark, the tree will die, and if the world loses a third of its trees, the world will die. We live less that five minutes without air and the trees give us air we breathe. We live less than five days without water, and trees are absolutely essential in the water cycle. We live less than five weeks without food, and without the trees we could not grow food.” (Filson, Bruce K. October 7, 1982, Western People, p. 5)
Curriculum resources found online which help learning in the afforestation areas which are mixed woodlands resembling a boreal forest ecosystem on the prairies.
“Trees exhale for us so that we can inhale them to stay alive. Can we ever forget that? Let us love trees with every breath we take until we perish.”
Munia Khan
Many towns, cities and communities are taking part in Arbor Week celebrations to appreciate trees and their many benefits.
It is not so much for its beauty that the forest makes a claim upon men’s hearts, as for that subtle something, that quality of air that emanation from old trees, that so wonderfully changes and renews a weary spirit.
In a forest of a hundred thousand trees, no two leaves are alike. And no two journeys along the same path are alike.
Paulo Coelho
“Celebrate by taking a walk in the park, head out to a local forest or just notice the trees in your community and even on the street that you live on,” Saskatchewan Minister of the Environment Vicki Gauthier said. “Just have some appreciation for all the hard work that they are doing for us.”

Today there is a new word for you! In the Richard St. Barbe Baker Afforestation Area, it may be a better autumnal word. However, today, this marvellous winter day, this word is shared especially for you.
Have you ever heard of psithurism before? Well perhaps not the word, but, and however, you probably did enjoy sitting in a forest listening and marvelling at the wind rustling through the leaves. And it is a glorious feeling to hear the wind moving through the branches of the trees. That experience is psithurism.
So next time you marvel at the shimmer of the trembling aspen leaves when the slightest breeze rustles those amazing leafy “coins” of the “money tree,” think of psithurism. As you walk through the forest in the winter and a silverberry or snowberry bush still remains with leaves, remember psithurism and rejoice.
So today, the challenge is passive and quiet. The challenge is to set yourself still and quiet in the forest, and experience psithurism. So please do Take It Outside, and celebrate this WinterCity YXE opportunity to have a Winter Staycation in Saskatoon.
“To be standing together in a frosty field, looking up into the sky, marvelling at birds and revelling in the natural world around us, was a simple miracle. And I wondered why we were so rarely able to appreciate it.”
Lynn Thomson
“Creative expression, whether that means writing, dancing, bird-watching, or cooking, can give a person almost everything that he or she has been searching for: enlivenment, peace, meaning, and the incalculable wealth of time spent quietly in beauty.” -Anne Lamott
How can we determine which of the roses are which in the Richard St. Barbe Baker Afforestation Area and George Genereux Urban Regional Park forest communities?
Prickly Rose (Rosa Acicularlis Lindl.) the Prairie Rose (Rosa arkansana) and Wood’s Rose, or Wild Rose (Rosa woodsii) are perhaps easiest to identify in mid-June when the pink blooms appear. These blooms last perhaps two weeks, giving way to the fruit or the red or reddish-orange rose hips, which again make this bush easy to identify. Whereas, all rose bushes have thorns, the Prickly Rose is abundant with weak thorns.
Rose in the Richard St Barbe Baker Afforestation Area
Native Rose Bush blooming in June
Prickly Rose (Rosa Acicularlis Lindl.) the Prairie Rose (Rosa arkansana) and Wood’s Rose, or Wild Rose (Rosa woodsii) all grow well across Saskatchewan, in the quaking aspen parkland, and also the grasslands as well as the northern boreal forests. This bush is often found where the soil has been made acidic due to the contributions of spruce or pine, and will grow in forests comprised of quaking aspen (Populus tremuloides), and cottonwood (Populous spp.) all of these trees making up both the afforestation areas – Richard St. Barbe Baker Afforestation Area and George Genereux Urban Regional Park forest communities.
The rose bush, will make its appearance in places where rodents or other animals disturb the soil, loosening up the soil which then receives the rose seed (achene) in an area conducive to growth. Or, in fact, these animals may also be disturbing the rhizomatous roots which are laying below the soil. Adventitious buds form on roots near the ground surface, on damaged stems (as on the stumps of cut rose shrubs), or on old roots. These roots develop into above-ground stems and leaves. A form of budding called suckering is the reproduction or regeneration of a plant by shoots that arise from an existing root system. The rose bushes do not tolerate a closed forest canopy as they are only moderately shade tolerant.
What is the difference between scientists?
A botanist is an expert in or student of the scientific study of plants, based on the Greek root botanikos, from botanē meaning plant, and -logy from French -logie or from Greek / medieval Latin -logia meaning the study or interest in a subject. A biologist is a scientist who focuses on living organisms, including plants and animals from Greek bios ‘life’ + -logy. A naturalist, on the other hand, is a person who studies or is an expert in natural history, especially a zoologist or botanist. Historically, if one lived back in the late 14th century, the Middle English word for a “natural philosopher or scientist” was naturien instead of naturalist.
A citizen scientist is anyone who aids in the collection and analysis of data relating to the natural world, and reports them to a collaborative project with professional scientists. Some wonderful ways to report data from the Richard St. Barbe Baker Afforestation Area and George Genereux Urban Regional Park forest ecosystems, would be for citizen scientists to make observations and send them off on their computers or by using phone apps. iNaturalist, ebird, Bird Studies Canada, EcoSpark, eButterfly, FrogWatch, PlantWatch, Project Noah, Project BudBurst, Nature’s Notebook, LeafSnap. The Native Plant Society of Saskatchewan has a Saskatchewan Master Naturalists program. The Saskatoon Nature Society conducts regular field trips to connect people and nature. Jane’s Walks and The Wild About Saskatoon Walks in the spring month of May introduce the visitor to both the afforestation areas – Richard St. Barbe Baker Afforestation Area and George Genereux Urban Regional Park forest communities.
PlantWatch The PlantWatch program enables citizen scientists to get involved by recording flowering times for selected plant species and reporting these dates to researchers, who work to identify ecological changes that may be affecting our environment. By reporting on the PlantWatch species found in your community, you can help researchers discover how common plants are responding to climate change and track where changes are taking place in Canada, and at what rate.
Project BudBurst Project BudBurst is an app to receive data on the timing of leafing and flowering of trees and flowers Project BudBurst also offers climate change and phenology materials and tools
LeafSnap The user of the LeafSnap App needs to extract the leaf and place it in a white background and then take a picture through the app to get the leaf identified automatically.
Reporting your findings on facebook, or social media, and using the hashtags #ScienceAroundMe., #RichardStBarbeBakerAfforestationArea, #GeorgeGenereuxUrbanRegionalPark, #Saskatoon, #YXEGreenStrategy are some excellent ways to track the eco-system out at the afforestation areas.
What is taxonomy?
Botanists refer to a taxonomic key produced by a taxonomist when speaking in reports, publications or at conferences about plants.
Taxonomic Ranks, and Binomial Name Genus and Species
“Nature produces individuals, and nothing more. She produces them in such countless numbers that we are compelled to sort them into kinds in order that we may be able to carry them in our minds. This sorting is classification—taxonomy.” ~C.E. Bessey Though Aristotle (384-322 B.C.) may be regarded as the first ever naturalist, Theophrastus (371–287 B.C.), his pupil, is recognised as the father of Botany. However, the starting point for modern botanical nomenclature is Linnaeus’ Species Plantarum of 1753 which featured a key event as Linnaeus adopted the system of using binomial names for plant species. Binomial nomenclature is a two-naming system featuring the first part of the name – the generic name– identifying the genus to which the plant or organism belongs, while the second part – the specific name or specific epithet – continues on to identify the species. The classification of something, living things or organisms is the science called taxonomy. Ataxonomist groups organisms into categories. A plant taxonomist may study the origins, and the relationships between different types of roses. Taxonomists may come up with their own system of plant taxonomy or “taxonomic system
Taxonomic Chart Blank
Figure 1 Complete the Taxonomic Ranks for the Saskatchewan Wild Rose Method 1 Use the given relationships below used by botanists Method 2 Create your own Taxonomy Chart, Taxonomic Section titles, and plant names.
In Saskatchewan roses have the same taxonomy through to the genus “Rosa.” Of all the taxonomic classifications, the clade ‘Rosids’ is the most challenging taxonomic category to describe.
Kingdom: Plantae. Plantae means plants, featuring multi-cellular living things with predominantly photosynthetic cells.
Rosales Classification taxonomy key according to the USDA
Clade: Angiosperms. Angiosperms are plants with fruit. Angiosperms are land plants which produce seeds within an enclosure such as a fruiting body. Angiosperms is derived from the Greek words angeion (“case” or “casing”) and sperma (“seed”).
Clade: Eudicot. Eudicots have two seed leaves which provide nutrients to the embroyo from the Greek words eu, well or good, dio two, and kotylidon seedlobe. Eudicot as a reference first proposed that there is a pair of leaves, or cotyledons, in the embryo of the seed. Currently the classification refers to angiosperms which are not monocots.
Order: Rosales. Those rosids which are nitrogen fixing or those plants which belong to the nitrogen fixing order are given the name Rosales.
Family: Rosaceae. The subfamily of rosaceae is Rosoideae, those plants with rose hips. Rosoideae which are those genera bearing aggregate fruits that are made up of small achenes or drupelets, and often the fleshy part of the fruit is the receptacle or the stalk bearing the carpels (female reproductive organ of a flower, consisting of an ovary, a stigma, and usually a style). In taxonomy, that which separates the family Rosaceae from the order Rosales is that the plant ovaries and achenes (seeds) are hidden inside the round hypanthium.
Genus: Rosa. Two of the ways that the rosaceae family can be narrowed down to the genus Rosa are; if the plant features many pistils and prickly stems. chapter: genus Rosa (Part 3).
Species:R. Acicularlis Lindl., R. arkansana, R. woodsii
Biological Classification Chart
Figure 2 From the information above fill out the Biological classification Chart. What happened? Have there been changes in the Linnaean system? Why? For extra points, how many different kingdoms are there?
In the USDA classification
Kingdom Plantae refers to plants.
Sub-Kingdom Tracheobionta are vascular plants with lignified plant tissues (called vessels or trachea) for moving water and minerals around the plant.
Super-division Spermatophyta are seed plants. Seed plants are divided into two groups Gymnosperms and Angiosperms.
Division Magnoliophyta are flowering plants. Plants in Magnoliophyta were formerly classified as angiosperms.
Order Rosales feature nitrogen fixing flowers with four or five petals and the blossoms are flat or cup-shaped. They also have fleshy fruit.
Activities and questions
Design, construct and evaluate the effectiveness of a taxonomic classification technique that demonstrates the scientific principles underlying the identification of plants and how to differentiate one plant from another.
Evaluate, compare (find the similarities) and contrast (find the differences) to weigh the effectiveness of more than one of the previously devised botanical classifications. Debate the issue with supporting arguments pro and con.

“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.
“In the stillness of the mighty woods, man is made aware of the divine”

A ramet is an individual plant belonging to a clone. The botanical term for a sucker is ramet. The clone originates from one ortet. An ortet is the original or mother plant. A clonal colony is also referred to as a genet. A genet is the group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor. In plants, an individual in such a population is referred to as a ramet. All plants (ramets) reproduced asexually from a common ancestor (ortet) and have identical genotypes which means it is an exact clone or perfect copy of the original ortet. A genotype is the genetic constitution of an individual organism.
The Trembling Aspen May 25, 2019
Tomáš Herben of the Department of Botany, Faculty of Science, Charles University and at the Institute of Botany, Czech Academy of Science relates rhizomes to clonal growth. Rhizome is from both Latin and Greek root rhizoma meaning “mass of tree roots”, and from the root rhizoun meaning “cause to strike root, root into the ground” and from the Green rhiz meaning “root” and -ome. In botany, rhizome is a horizontal, underground plant stem which is able to produce the shoot and root systems of a new plant. Duana A. Pelzer, also states that “Aspen (Populus tremuloides) dominates the southern treeline in western Canada, has long‐lived below ground connections between mother and daughter ramets, and reproduces vegetatively via resprouting rhizomes.” The Trembling Aspen clone can be called rhizomatous.

Scientists, foresters or gardeners can practice vegetative propagation using rooted cuttings, grafting, or tissue culture. In the case of the Trembling Aspen, the original plant is also called the ortet.
The Trembling Aspen root suckers are produced from meristems featured in the cork cambium of the root systems. The Cambium is a layer of tissue between the wood and the bark from the Latin cambium meaning “exchange” and Latin cambiare “change. The cork cambrium, also called a phellogen, produces an outer protective barrier or corky tissue, and an inner phelloderm- a thin, food conducting vascular tissue.
The Trembling Aspen tree bark May 25, 2019
The roots twist, coil and undulate underground. Growing sideways, laterally, they do not reach lower than 40 cm (16 inches) below the surface of the soil and most often stay within 2 to 10 cm (1 to 4 in) from the soil surface.
A meristem is a collection of cells forming plant tissue in the zones where plant growth can take place. These undifferentiated cells (meristematic cells) have the capability for cell division, promoting growth and change. Meristem comes from the Greek root “merizein” which means “to divide” which is the main function of the merismatic cells, to change and divide thus providing new growth for the tree. Differentiated plant cells cannot produce new growth, as they cannot change.
The shoots develop following apical dominance. Apical dominance occurs when the shoot apex inhibits the growth of lateral buds so that the plant may grow vertically upwards towards the light. These shoots however, lie in wait, remaining dormant due to hormones called “Auxin” expressed by the main Trembling Aspen clone. High soil temperature, depletion of carbohydrate food sources, or excess soil moisture may inhibit the formation of suckers. If the Aspen Grove is disturbed, the hormonal balance is upset within the Trembling Aspen grove. There is a decrease in Auxin allowing meristem to develop into buds, then into shoots above ground, finally developing fully producing ramets which can be visibly seen above ground as part of the Trembling Aspen grove. Suckers originate after disturbances such as clearcutting, girdling, tree defoliation or fire.
The Trembling Aspen Dioecious Catkin or Ament May 25, 2019
When the suckers start to form, the parent root changes. The suckering rhizomatous root system has four parts:
The root collar, stump or root cap
The distal parent root
The proximal parent root
The adventitious roots
The root collar is the underground area of the Trembling Aspen sucker where it adjoins the stem. This root collar is the protective layer, so that apical meristem (upward changing new growth) is not affected by rocks, dirt or pathogens (germs.) The sucker roots and the parent roots cannot be distinguished from each other at the root collar, root cap or stump.
The distal parent root grows quite large to accommodate the new sucker formation. The distal parent root fills with juicy sap, and is quite succulent and tender. Distal means situated on the outside edge away from the point of attachment to the parent.
The proximal root which is on the close side of the root collar, or stump formation. Proximal means to be on the nearest to the point of attachment.
The adventitious roots of the newly initiated root suckers reveal growth downwards on the distal end of the roots reaching down to the root cambium of the Trembling Aspen clone or grove. Adventitious means formed accidentally or in an unusual anatomical position. These sucker roots will rely on the parent root for water and nutrients for the first few years. In some cases the suckers rely on the parent roots for more than 20 years. This interplay between parent root and ramet gives the sucker a distinct advantage over Aspen seedlings and other species arising on the forest floor.
Whereas shoots arising inside the meristem are one way to give rise to shoots as above, there are also shoots which arise from the exterior surface of Aspen roots from pre-existing primordia. It is believed that these primordia arise from injury or disturbance to the root system, perhaps by a grazing animal. Primordia comes from the Latin root prīmōrdiālis which is the earliest stage of development of the organism.
Root sprouting is the most commonly seen means of reproduction for the Trembling Aspen. This is referred to as vegetative asexual reproduction.
The Trembling Aspen is also referred to as the Quaking Aspen (Populus tremuloides Michx) Leafy branchlet, Female Ament or catkin, Young Male Ament or catkin, Fruit, Floral Bract.
A Trembling Aspen grove or stand of trees is connected underground by this common root system originating from the ortet. Each Aspen Clone is dioecious. One Aspen stand of trees may be composed of a mosaic of clones with their roots interspersed with each other. Dioecious means that there are distinct male and female organisms, or boy and girl clones. A stamen is the pollen producing male organ of the flower. Pistils arise on the flowers of the female Trembling Aspen stands, and feature a base ovary, a style or pillar which extends from the ovary to the stigma. The stigma is sticky enabling it to capture the pollen from the male Trembling Aspen clone.
The Trembling Aspen Dioecious Catkin or Ament
A Trembling Aspen feature aments, also referred to as catkins. Each catkin bears many tiny dense flowers. The name catkin comes from the German root “kätzchen,” or in Dutch “katteken” meaning kitten. The aments look like the furry tail of a kitten. The catkins can be anywhere from 1 to 8 cm in length (1-1/2” – 3”) The flowers with red stigmas are female flowers. The flowers bearing black, dark anthers are male flowers. The seeds will spread in the wind across distances of 500 meters (1,600 feet) up to several kilometers in heavy winds. The seeds are plumose, which means having many fine filaments or branches which give a feathery appearance. Seedlings have barriers to establishment because early spring rainfall in the semi-arid prairie regions may be followed by a dry period ~ killing newly germinated seedlings.
The Trembling Aspen Dioecious Catkin or Ament
Trembling Aspen will hybridize, or cross with other species of poplar trees (Populus)
The extent of a single Trembling Aspen clone of trees can be determined by several features; morphology, and phenology. These two methods bring in the observation of the leaf size and shape, the character and colour of the bark, and the changes in the season. Morphological analysis is the study of the form and structure of organisms and their specific structural features such as the outward appearance of the shape, structure, colour, pattern and size of the visible aspects. Morphology has as its roots the Greek word, morphé “form” and logos “the study of.” The study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation) is the science referred to as phenology. Phenology means the study of the influence of climate on recurring natural phenomena, and is derived from phainō, which is Greek for “to show, to bring to light, make to appear” and logos.
Taking the observations one step further would be to employ a procedure called digital morphometrics. This digital approach utilizing scanned leaf images carefully tracking the location and statistics of each leaf, and comparing the digital scans of each leaf recording the analysis and observation of the morphology of each digital leaf scan. Specific and unique clone signatures appear under the observation of discernible patterns.
Aspens feature leaf dimorphism which arise from two types of leaflets, featuring short fixed shoot (stem) growth, and long free shoot growth. Short shoots can only produce embroynic early leaves, and are the very first set of leaves which appear in the spring from the winter bud. Embroyo is from the Greek embryon, “a young one”, or “one that grows at an early stage of development.” This is referred to as the spring flush. The first late leaves are also present in the winter bud, but they are arrested primordia or stopped at the beginning. Primordia comes from primus meaning ”first” and ordior “to begin”.
The Trembling Aspen Autumn foliage
Lateral long shoots may produce “early” or “late” leaves. The fact that the long shoots can produce two types of leaves means that they are called heterophyllous stems or shoots. Heterophyllous meaning having two different kinds of leaves on the same stem comes from the Greek root heteros meaning “other”, and phyllon, “leaf”. Late leaves have more variety in their shape than the early leaves. Gland-tipped teeth are featured around the leaf margins on late leaves only.
A Trembling Aspen Clone leaf flush will occur at the same time because clones share the same genotype. Likewise, since the Trembling Aspen genet is all one clone, the entire genet will change colour all at once in the autumn.
Scientists have studied how to differentiate one clone of Trembling Aspens from another, and there is much discussion and preferences stated on the criteria and methods used. Hana Jelı´nkova et al have determined that finding the unique signature morphological traits to be superior to the use of spring phenology for successful analysis.
Spring phenology is more accurate than autumn phenological changes according to Michael Grant, and J.M.I. McGrath et al wrote that the phenology during spring flush showed a variety in morphology depending upon climate change variations. Both first and second leaf flushes, and their characteristics (morphology) were studied by Samuel B. St. Clair’s team. Defoliation of the leaves by insects, may require the trees to flush out a second time, as would drought and temperature extremes such as a late spring frost causing damage and defoliation of the first flush. Defoliation is to destroy or cause widespread loss of leaves.
The Trembling Aspen Leaflets and Dioecious Catkin or Ament May 25, 2019
The size and shape of leaves showed a variety between Trembling Aspen groves depending upon if the trees were in an area of elevated oxygen or Carbon Dioxide. In an interesting data collection, Reimo Lutter et al studied spring and autumn phenology on the Aspen tree from one year to the next, and found that the growing season has been lengthening.
“The timing of bud break and bud set represents events in survival and growth, discernment of these mechanisms and their interactions with climatic variables is a key to understand the consequences of the projected climate change for Populus forests”(Sivadasan, 2017). Leaf phenology has been shifting in response to earlier leaf flushing due to warm winters in relation to climate change state Yongshuo et al. Now then, Joyce G. Greene suggested that it would be wise to look at six different features to seperate Aspen clones;
“Sex
Time of leafing, and of leaf fall
Spring and Autumn leaf colour
Shape and Size of leaves,
Leave serration
Pubescence of dormant buds.”(DeByle, 1985)
Burton V. Barnes developed another set of criteria for distinguishing clones, by season and in order of usefulness.

“Children’s experience with the natural world seems to be overlooked to a large extent in research on child development, but it would be interesting to examine children’s early experiences with nature and follow how those experiences in nature and follow how those experiences influence the child’s long-term comfort with and respect for the natural world ~ comfort and respect…Given the power of nature to calm and soothe us in our hurried lives, it also would be interesting to study how a family’s connection to nature influences the general quality of family relationships. Speaking from my own personal experience, my own family’s relationships have been nourished over years through shared experiences in nature ~ from sharing our toddler’s wonder upon turning over a rock and discovering a magnificent bug the size of a mouse, to paddling our old canoe down a nearby creek during the children’s school years, to hiking the mountains.” ~ Martha Farrell Erickson
“Healing the broken bond between children and nature may seem to be an overwhelming, even impossible task. But we must hold the conviction that the direction of this trend can be changed, or at least slowed. The alternative to holding and acting on that belief is unthinkable for human health and for the natural environment. The environmental attachment theory is a good guiding principle: attachment to land is good for child and land.” ~ Richard Louv

“They recognize that while knowledge about nature is vital; passion is the long-distance fuel for the struggle to save what is left of our natural heritage and ~ through an emerging green urbanism ~ to reconstitute lost land and water. Passion does not arrive on videotape or on a CD; passion is personal. Passion is lifted from the earth itself by the muddy hands of the young; it travels along grass-stained sleeves to the heart. If we are going to save environmentalism and the environment, we must also save an endangered indicator species: the child in nature.”~ Richard Louv.

The Elm Bark Beetles,Hylurgopinus rufipes (Eichhoff), shows an attack as red sawdust appears on the bark of the elm tree indicating the presence of small round holes where the beetles enter. Another sign of Dutch Elm disease occurs in July, “Flagging” manifests as yellow, curling leaves and wilting foliage, and defoliation in the crown of the tree. These little insects may carry the Dutch elm disease from a diseased tree to a healthy one. “Staining “will show evidence of red streaks through the sapwood in infected twigs. These little beetles can overwinter in the outer bark of the living elm, or survives as larvae inside the bark of a dead elm. “Dutch elm disease is a fungal disease that blocks trees’ water systems, killing them within one to two years.” Star Phoenix
Elm bark beetles are attracted to weak, and sickly trees. “Dying branches on an elm increase the chances that a beetle, possibly carrying the DED fungus, will make its way to your tree.” Fact Sheet # 3 Give your elm trees a healthy foundation with watering and retaining leaves for fertilizer at the base of the tree.
“The most effective management strategy for the elm bark beetle is to deprive it of its breeding habitat. This involves keeping elm trees healthy and removing dead and dying branches. It is necessary to dispose of any branches or wood from a fallen elm tree and either remove the stump or render it uninhabitable. Under no circumstances should elm wood be left lying around or stored for firewood or other purposes.” City of Saskatoon
“If someone brought in infected wood that had the beetle in the wood, that beetle would fly over top of a healthy tree and start to go into that healthy tree spreading the disease.” Michelle Chartier, Superintendent of Urban Forestry and Pest Management. CBC News
Tree banding is a preventative measure (so that the species which travels down the trunk of the tree to overwinter under the bark at the base of a live elm cannot make its downward journey. For this method to be effective, the band must be placed on the Elm tree by late September, and should stay on the tree until spring), similar to the practice applied for cankerworms.
American elmUlmus americana is the primary host tree for the native elm bark beetle Hylurgopinus rufipes. Siberian elm Ulmus laciniata is the native host tree species for the Smaller European elm bark beetle Scolytus multistriatus in the United States.
“After the beetle feeds in a tree infected with Dutch Elm Disease, the fungus spores attach to the back of the beetle, causing it to infect the next healthy trees.
An elm tree in Regina had to be removed last year due to DED and the city has had to remove 94 trees since the disease was first detected in 1981.”
“Saskatoon recorded its first case of DED in July 2015.“Global News
In the afforestation area, and across Saskatchewan, an Elm tree pruning ban is in effect between April 1 to August 31. The elm beetles are the most active during these months, and pruning the Elm tree during this time frame will increase the chance of infection. The newly created cut attracts the elm beetles.
Do not store, transport or use Elm Wood as in firewood or for other purposes. Report any Elm trees with signs of elm beetle distress to 306-975-2890. Only dispose of elm wood at the City of Saskatoon Landfill and never ever at a compost site.
“SOS Elms Coalition is concerned about the health of Saskatchewan’s community tree populations, in particular the threat of Dutch Elm Disease.”

“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.

“The fate of an individual or a nation will always be determined by the degree of his or its harmony with the forces and laws of Nature and the universe. Man is not alone in the universe but is surrounded by sources of power, harmony and knowledge. The fullness of life depends upon man’s harmony with the totality of the natural cosmic laws. Our individual evolution is a job that has to be carried on day by day by each individual himself. It is a livelong task” Richard St. Barbe Baker
The Poplar his branches richly green
Broad to the winds did wildly fling;—
The first in beauty and in power,
All bowed before the forest-king.
But ere its brilliant leaves were sere,
Or scattered by the Autumn wind,
The voice merged into the buzz of autumn noises, and footsteps and other conversation
the wild geese went and came unchecked
Geese are Weed Destroyers they are close grazers
Very valuable in ridding grasslands or fields of troublesome weeds.
As the blear autumnal light burst forth
The Saskatchewan woodpecker drums
this musical rapping may be heard.
“He alternates his tapping with his stridulous call,
and the effect on a cool, autumn-like morning is very pleasing.”
“In that vast evergreen forest Nature works in perfect rhythm; roots digging deep or exploring nearer the surface for food and moisture. Imperceptibly Nature builds those mighty pillars with aisle innumerable, arches multiplex, in the cathedral of the forest.” Richard St. Barbe Baker

“I love to see, when leaves depart,
The clear anatomy arrive,
Winter, the paragon of art,
That kills all forms of life and feeling.
Save what is pure and will survive.”
Roy Campbell
And yet, now the leaves are coming back. The leaf roller and the tent caterpillar have gorged, the feast has ended with the last leaf. It is now the era for the trees to once again send out their leaves and green again.
It has been a better year for some insects. Still the bees are not hovering as much as yore. The butterflies have made a small comeback. Will the abundance of tent caterpillar and leaf roller be a sign of times to come, and hope that all insects may thrive again?
What a piece of work is a man,
how noble in reason,
how infinite in faculties,
in form and moving how express and admirable,
in action how like an angel,
in apprehension how like a god!
the beauty of the world,
the paragon of animals. ~William Shakespeare
And would you agree with Hamlet, is man the paragon of animals? The ornithologist may pass his life in one place, but he can never say “I have finished” and though they have traveled nought, they know the morrow may bring some new bird or new fact. The astute observation, ahd attention to detail this association with the birds adds to the joy of life! How is spring set apart from autumn, what new meanings comings and goings of the waterfowl, the songbirds, raptors and all give to the changing seasons; the very air is made eloquent by their calls and songs. Why should we not all be gladdened and “come at these enchantments”?” It is impossible for us not to love whatever is lovely, and of all living things birds were made most beautiful ~ says the bird watcher.
And yet~ recent researches and news stories have emphasized the practical importance to human society of entomological study, and insects will always be a source of delight to the lover of nature. Among the manifold operations of the myriad of living creatures few have more strongly impressed the casual observer or more deeply interested the thoughtful entymologist than the transformations of insects. Everyone is familiar with and can ramble on at length the main facts of such a life-story as that of a moth or butterfly.
And now~ have ever when out in nature, have you become aware of another, one who is taking time to behold mankind. When you are out truly there is a pace, and nearer to wildlife, they do not let others draw across that distance, yet, although their curiosity about humans was great. Have you been out, and seen that from the way they go circling round, stretching their necks to get a good view, and one might only feel and perhaps come to the conclusion that mankind perchance was of a different species of animal from those with which they were familiar.
The seasons come and go. Summer turns to fall. “What a piece of work is a ____________, the paragon of animals.” Is it truly that man is the paragon of animals? What do you say? Is it truly in the eyes of the beholder? Or is it what they focus upon? Or what they can see?
Will the entymolgist spy the metamorphic rock of the geologist? Can the ornithologist spy the butterfly cocoon of the entymologist? Will the artist behold the scene with the same eyes as the surveyor? The seasons come and go. Winter turns to spring. Does the paragon of animals ever change? “What a piece of work is a ____________, the paragon of animals.”
Nature’s beauty is a gift that cultivates appreciation and gratitude. Louie Schwartzberg Mwanner

See how nature – trees, flowers, grass – grows in silence; see the stars, the moon and the sun, how they move in silence . . . We need silence to be able to touch souls. ~Mother Teresa
“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
Stand firm. Grip hard. Thrust upward to the skies. Bend to the winds of heaven. And learn tranquility. ~Richard St. Barbe Baker
We feel that our greatest victory remains to be won when man will realize his oneness with the trees, the creatures and with all living things, not ours to destroy, but to be handed on for the enjoyment of future generations. – Richard St. Barbe Baker.
