1. Forestry

2. What do we use forests for?

3. An Older View of Canadian Forestry https://www.youtube.com/watch?v=upsZZ2s3xv8

4. Forest Facts Forests cover 42% of Canada’s total area Only Russia and Brazil have more forest

5. Forest Facts One of every sixteen jobs in Canada depend on the forest industry The forestry industry produces products that are worth over $80 billion each year Over half of these products are exported to other countries

6. Forest Facts Canada is the world’s second largest producer of Pulp and Paper Canada exports more pulp and paper than any other country Pulp

7. Types of Forests Coniferous Deciduous Mixed Forests

8. Coniferous cone bearing trees that keep their leaves all year round. Examples include Spruce and Pine. Coniferous trees account for 63% of forests. These are called “Softwood”.

9. Deciduous trees that lose their leaves every fall/winter. Deciduous trees account for 22% of forests. These are called “Hardwood”.

10. Mixed Forests Are a mixture of conifers and deciduous trees. These make up 15% of Canada’s forests

11. Commercial vs. Non–Commercial forests Commercial forests – those that have trees that can be harvested (cut down for $) Non-Commercial Forests – those that are unlikely to be cut down for industrial use

12. Commercial Forests they exist in warm/wet areas of Canada where the trees grow faster (southern areas) Close to road, railways and waterways – good for transportation Non-commercial Forests Cooler/dryer climates make the trees grow slower (northern area) Far from markets – expensive transportation What determines whether a forest is commercial or non-commercial?

13. Look at the map of Canada’s forest regions on page 300 On your map of Canada, please describe what types of forestry are occurring in each province Commercial vs. non commercial Sawmills vs Pulp and paper

14. Pulp and Paper Industry The pulp and paper industry contains huge factories that break down trees into individual fibers and turns them into paper products. Lumber Industry Sawmills are a much smaller operation than a pulp and paper mill. These plants cut trees into smaller pieces in order to make timber, plywood, or cedar shingles.

15. Pulp and paper Mills Majority are located in Ontario and Quebec. Pulp and paper requires the trees to be completely broken down. ◦ This requires a great deal of energy. Less energy will be used if the trees being broken down are a smaller size. ◦ Trees in Ontario and Quebec are smaller because of the shorter growing season and low levels of precipitation.

16. Sawmills The majority of sawmills are located in BC. Sawmills like to use large trees. The larger the tree, the more lumber it can produce. The largest trees in the country are found in BC due to the narrow temperature range and heavy precipitation.

17. Types of Logging Observe the pictures on the following slides and describe what you see.

18. Describe what you see

20. Selective Cutting Harvesting only mature trees of the desired size, type and quality Much less disruptive to the forest environment Costly process – costs more $$ and takes more time to collect enough trees. No replanting needed

21. Shelter Wood Logging Involves clear cutting only parts of an old growth forest ◦ No replanting is necessary. Not as efficient, don’t get as many trees. The forest will only be partially uniform.

22. Clear Cutting Loggers remove all trees The majority of logging companies use this method. The area is replanted The new forest grows up uniformly (same species, size and age of trees) – makes for easy logging next time Fastest and cheapest method

23. Pests and Diseases The amount of forest damaged every year by pests and diseases is greater than the amount harvested by companies. Some of the more common pests are tent caterpillars, pine beetles and gypsy moth. Pests can get inside the bark and eat away at the tree.

24. Forest Fires Forest fires are not always a bad thing. New trees are able to regenerate quickly in a burned forest. The cones from some pine trees are better able to open with some heat. The fire allows them to do this and this will cause the seeds to fall out of the cones.
