  1. KINGDOM PLANTAE - TAXONOMY Dicots Monocots Angiosperms – Enclosed Seeded Gymnosperms – Naked Seeded Subphylum Spermopsida – Seed Plants Subphylum – Pteridophyta- Ferns Tracheophyta – Vascular Plants Bryophyta - Mosses Chlorophyta – Green Algae Phaeophyta– Brown Algae ALGAL Phyla Rhodophyta– Red Algae

  2. GINKOS – 1 species remains CYCADS – 100 Species • GYMNOSPERMS • Phylum Tracheophyta • Subphylum Spermopsida – “Sperm” = “Seed” CONIFERS

  3. GYMNOSPERMS- “Naked Seeded”Most Common Class – The Conifers • Typical coniferous forest primarily spruce, fir and pine. • Not all coniferous forests have the same appearance, some conifers are better suited for a warmer wetter climate.

  4. This is an old-growth coniferous forest consisting of Giant Sequoia trees

  5. CAUTION WATCH FOR FALLING LUMBER

  6. Did you ever go back and study your family TREE?

  7. CAPILANO SUSPENSION BRIDGE – North Vancouver

  8. Here is a coniferous forest located in a temperate rainforest. In a temperate rainforest there is year-round precipitation through four seasons; typically warm summers and cool winters

  9. CHARACTERISTICS COMMON TO CONIFERS • “Conifer” – Means “Cone Bearer”. • Leaves are adapted to take needle shape, a thick cuticle and reduced surface area allows conifers to grow in dry cold climates without losing too much water. • Almost all conifers are evergreens : They do NOT shed their needles seasonally.

  10. Conifer wood has growth rings of XYLEM The meristematic tissue called VASCULAR CAMBIUM produces XYLEM to the inside and PHLOEM to the outside.

  11. AGING A TREE A Forestry Technician uses a tree borer to take out a tree core sample

  12. There are two types of Xylem rings. Spring Wood (Xylem) is a lighter colour. - Rapid cell division gives rise to very large cells Summer Wood (Xylem) is darker. - Tissue grows slower and cells are more compact

  13. THE CONE BEARERS Mature female (ovulate) cone

  14. Several female cones on a Ponderosa Pine Clusters of female cones on a Spruce Tree

  15. This is a European Larch a close relative to a Tamarack. Its still a conifer (cone-bearer) but its not a true “EVERGREEN” What’s Wrong With This Picture? Male Cone Female Cone

  16. Conifers can be classified by the following: Characteristics of the bark Needle shape, length and texture Cone size, shape and scale patterns

  17. A Renewable Resource Properties: LIGHT but very STRONG These properties make it a perfect building material http://www.youtube.com/watch?v=q3554jk38qU

  18. We need trees but need to be careful in logging practices and reforestation. Clear Cut Logging Erosion of Soil
