COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Describe the basic function and composition of a tree's vascular system.

2.  Identify the most common structural, biological, and cultural defects associated with urban

    trees.

3.  Compare and contrast various procedures and techniques used in tree pruning and tree care.

 

Objectives:

At the conclusion of this course, the student should be able to:

1.   Define the practice of arboriculture.

2.   Explain the structure and function of the buds, leaves, wood, and roots of trees.

3.   Explain the concept of Compartmentalization Of Decay In Trees (CODIT).

4.   Explain how plant characteristics such as growth habit, texture, and color can be used in tree

      identification.

5.   Explain the principles of water uptake, transpiration, and the movement of water in the soil.

6.   Explain the significance of urban soils as they apply to nutrition, irrigation, tree health, and

      tree establishment.

7.   Describe the essential nutrients that trees require, how these nutrients are absorbed and the

      advantages and disadvantages of different methods of fertilizer application.

8.   Summarize how a tree species' growth form and site characteristics inform the selection of

      the "right tree for the right place."

9.   Outline what to look for in selecting healthy, vigorous planting stock.

10. Illustrate proper techniques and procedures to plant and transplant trees, and explain how

      using proper techniques can improve survival chances and accelerate establishment.

11. Determine when a tree might be helped by the installation of cables, guys, bracing rods, or

      props.

12. Identify and describe the procedures, techniques and terminology used in various types of

      pruning.

13. Describe the various physiological disorders and injuries that can affect trees, and explain

      what treatments are appropriate.

14. Explain the philosophy of Plant Health Care (PHC) and describe its relationship with

      Integrated Pest Management (IPM).

15. Describe the methods and technology used to assess tree hazard potential.

16. Outline appropriate methods of managing trees during construction, including tree protection

      and preservation.

17. Discuss urban forestry and the environmental, economic, aesthetic, and social benefits and

      costs of trees.

18. Explain how to conduct a tree inventory and describe what information would typically be

      collected in a tree inventory.

19. Identify appropriate safety standards for tree care operations: describe tools, knots, and

      safety equipment used for climbing and working with trees.
