1. Forests and Mountain Ranges of Oregon

        - Name and place the 5 mountain ranges

        - Describe the types of trees in each (may be more than one for each mountain range)

        - Why? limiting factors, influence of climate and elevation

        - connect to dendrochronology

        - connection to fire

2. Succession and Fire

        - Fire triangle - what 3 elements are needed for fire

        - climate and weather pattern (fire season)

        - Fire history using dendrochronology and written records

- Fire dependent species in Oregon and how does that shape fire policy

- describe the 4 stages

- Describe the 2 types

3. Measuring Trees

        A. Tree Ring Studies - dendrochronology (website)

                - what is a tree ring?

                - What do narrow and wide rings indicate (limiting factors)

                - Define cross-dating

                - primary uses for creating a chronology using tree rings

        B. Size of trees

                - Calculate Height

                - Calculate Basal Area

                - Calculate volume

- Describe methods for collecting this data including the materials

- What can you learn about a forest and its health from this information?

4. Nutrient Cycling and Niches

        - Carbon cycle

                - Describe the processes involved (photosynthesis in detail)

- Types of organisms involved in transferring carbon through the food chain (niche)

- What does the carbon cycle accomplish?  

- Nitrogen cycle

- Describe the role of nitrogen in living things

- How does it get from the atmosphere to the food web?

- Once in living things, how can it be returned to the soil?

- What organisms fix nitrogen (taking it out of the atmosphere)  in Oregon forests        

- Major impacts on water
